I know, you're the single one which are doing this, make something about Dacia Logan or Romanian cars please, I enjoy you a lot, hope you will be reaching 1.000.000.000 first
Honestly most of the things listed in the video ive really never heard of people believing The oil change mostly but everything else im just sure only a small amout of people believe
AC gobbles up 5-10hp, turn off the AC on a hot day climbing up a hill and you will notice a big bump in torque requiring less throttle input. I use the AC even when cold out to help with hold back descending hills in a lower gear...it drags that much.
@@jordanbanko5347 2011 Silverado Crew with a 4.8L. I live in a very hilly city like San Francisco. Even with a Diablo tune in the truck on a long hill I have to adjust my throttle to maintain speed when the AC kicks in and out.
Number 7 avoid first year of a car's production used to be true in the past but now due to Federal Regulations every subsequent year has to suck just as bad as that initial year
Only under 55 mph, you should add that in. Having the windows down at 55 makes the car much less aerodynamic resulting in the engine working harder to keep the car at 55 than if the A/C was on.
Exactly. Mythbusters tested this years ago. I believe in their tests AC was more fuel efficient from 30 mph. I guess it depends on the aerodynamics of a particular car.
Alex Murphy well increasing your airflow can/will increase your power output, though it depends on the car and the exhaust just how much of a difference it makes, and often bigger aftermarket exhausts are louder. However they don't necessarily make a car powerful you are right.
Louder exhaust CAN mean better fuel economy and engine performance due to lack of exhaust flow resistance. The difference only occurs with a properly installed performance exhaust system, though.
no it dont, clutches, gears, steering wheels all have a deadplay where they do nothing. as long as you dont go over that deadplay you can keep your feet on the clutch or your hand on the gearstick... just an other urban legend
press f to doubt. you wear out the shift forks because there is only a certain amount of clearnace and no designed deadplay into a manual trans shifter.
There is a reason nuetral can be engaged on a auto whilst the car moves, only saves fuel when coming down a mountain but it does save alot and only engage drive when car stationary or at low speeds
It's not like he's doing it intentionally. You see how he's moving his hands, then automatically resting his hand on the shifter? Chances are, that guy drives stick, but he was driving a friend's car or something like that in this video. As for doing it on stick, I do it because it feels good, and also because, once I have a good performance car, I'm going to be working on one handed steering in terms of racing, where it is actually useful, although not easy to do when it comes to high speed cornering
Pedro Rocha I hate hybrids , I hate hybrids , I hate hybrids , I hate hybrids , I hate hybrids , I HATE HYBRIDS!!!!!! Did I mention that I hate hybrids? And the pretentious Yuppie wannabes who drive them!
Brake issue on the 2009/10 fiesta what was a first year production model. And Ford state there was nothing wrong with the brakes on the cars and that it is a "soft touch brake system"... What having brakes feeling like they have air in them and feel like they won't stop your car will give you confidence in said car?? Changing the master cylinder makes the brakes feel sharp what says Fords didn't wanna do a mass recall... Truth is, first year owners help companies like Ford to find and fix issues with their new cars.
At my job we use vans, and when the new vw crafter came out, we got like ten of them. Until this, crafters have been known to be quite bulletproof, but out of these, nearly all went back to dealer with failed injectors, ECU's un DPF filters, within 20-30k km. First year car rule still applies.
No, jet fuel has more in common with kerosene. Some people also substitute AVGAS for race gas on high compression engines. But whatever. We mechanics are just trying to scam you and don't know what we're talking about.
It isn't. F1 uses conventional gasoline with 5.75% ethanol content. As the guy you're replying to just said: Jet Fuel is basically kerosene, a heavy oil. The only engines which can potentially burn jet fuel are diesel and jet engines.
I attended fueling school in the military and I can give you some advice on when not to fuel up at the station. If the fuel petrol truck just finished unloading than I suggest you get to another fuel station. The reason for this is when the new fuel comes into contact with the old fuel, it all mixes together and the water and dirt particles that separated from the fuel at the bottom of the tank are now mixed back in. If you're super anal about the fuel than I suggest you learn when the fuel truck makes its rounds. Have a few parts per million is not that bad. Either way, I hope this helped.
Not true at all. Modern fuel pump dispensers have a filtration system to reduce if not eliminate particulate matter. Dirt and sediment is almost non existent since storage devices are cleaned regularly.
Because we all know that every gas station changes those filters every 8,000 gallons.....sorry, worked at one, and not only was "water seepage" a norm, but so was changing the filter 90,000 gallons after its effective filtration life. gas stations are NOT the military Oscar!
The Mythbusters showed that the you get the best gas mileage with the windows closed and A/C off, middling gas mileage with the windows open, and appalling gas mileage with the A/C on
Speed also is a factor. At lower speeds around town, windows down and A/C off is better. At motorway speeds (80 kph or over) windows up and A/C on is better.
Just a couple of the many reasons why the only new car I'll even consider buying is the RX-9, whenever that comes out. Still not going to be buying that right out the gate, though, under any circumstances
@@ОлегОсипов-б9п Honestly, almost every company has turned shitty these days. I'm an old Nissan guy. I love cars like the 240sx and its Japanese cousins, I'm saving up to buy an R32, but I would never buy a modern Nissan, except for maybe a Juke R because that thing is fucking ridiculous
You have to consider How severe is your driving. Heavy traffic, dusty roads are considered as severe conditions. Highway Miles are not. So, If you drive only on the city and your car's manual says 10k , change the oil at 5k.
ahahahha my mom thought that if you turn off the a/c the engine will overheat 😂😂😂 i try to convince her that radiator is responsible for that task but she still stick with her thought😂😂😂
There is a Heat exchanger that is coupled to the normal a/c (So hot/cold not temperature and stuff) if your radiator is clogged and your engine is overheating putting the AC on full heat and full blow will cool it off.
Sean Allen You know as well as I do that NO ONE these days can leave their phone for one minute! ....or so it seems. But you're right. Most people dont use their phone while refueling but there are still plenty that do. Just remember to keep away from the ones refueling while using a cell phone with an antenna!😁
Sean Allen, As an ex-servo attendant I can tell you that there are a LOT of people who keep using their phone while filling the tank. Boy do they get upset when I follow company policy and don't turn the pump on till they put it away. PSA useless additional info. Most fuelling browser fires are caused by women. Now before you all come round to my place and string me up by the short and curlies, there is a reason why this is. Two actually. 1) Women are more likely to be wearing synthetic fibre clothing. (results in more static) 2) Women tend to use the auto fill more and so do not remain grounded to the nozzle while filling the car. (once again resulting in more static) Thus they have a greater chance to have a static discharge occur.
As for the first year thing its still true. There is known to have many issues that dont come to light until the car is been in use. So i would 100% never buy a first model year.
True, the AC motor draws power off the engine. Not only does it increase fuel consumption but it uses horsepower. I know this through doing gas mileage checks. I still think it is worth the extra fuel to stay cool though.
depends on the car. Just comparing similar era cars: I had a 1994 Toyota Corolla. Using the AC didn't seem to affect the power or MPG much. MY 1993 Subaru Impreza is another story. Turning on the ac dropped MPG by 5 and it was noticeably more sluggish while accelerating.
BlitzkriegRap that's a fuck load mate. 5-10% more fuel just from A/C is absolutely massive. BTW it's not like that at all. A/C affects low capacity, low torque engines more than bigger engines. The more capacity you have the less the a/c will leech your power, and the less you'll have to put your foot down and burn more fuel. A/c alone does not burn any more fuel. Your right foot does when your little Honda civic can't get up a hill with the a/c on.
Myth busters tested this, it's all about average speeds. When you average ~>40mph having your windows down makes a bigger aerodynamic drag on the car than having the A/C on.
actually. Mythbusters PROVED the last one. Driving with the windows down does have an effect on mpg because cars due to the extra drag. The effect is more significant in newer cars rather than older ones. A/C also has an impact on mpg. Which one of the two is worse depended on the speed you are going, the faster you are driving the worse windows down is.
I am not an expert, but going faster means less air can go inside due to aerodynamics, I think. So the faster you go, the less it should affect. (I'm half an engineer, but haven't gone this deep into physics)
im not sure of the exact reason, but if I had to guess its because the faster you are going the more air you have to push through. I have taken some physics courses but none are deep enough to be able to answer it scientifically. A more general way of explaining it though is if you do drive with the windows down, at high speeds you can feel more air hitting you while you are riding inside the car.
@@iandms1160 yea, I found the answer below, it does increase drag. Now I am curious if those wind deflectors found on some cars are actually reducing drag with open window, but I don't think anyone ever tested it.
I think from my experience, that meybe if u put vent on 1 and only slightly open back window (2 cm aprox.) u let air flow thru the car interior free and dont get drag from air entering thru vent intakte and building pressure in airfilter and car interior But, opened windows and increased fuel consumption depends on how big engine u have and how fast u go. On 3 Liter Diesel under 100 km/h u dont See diference, but whith 1 Liter petrol engine speeding 130 km/h whith opened Windows wil increase consumption meybe even 30 percent
Another few questions! 1. Do you play any games? 2. Do you have any modifications on your car? 3. What is your favorite car? 4. What car do you really want to own? 5. What types of cars do you like? Hope you reply to this! PS: Keep up the good videos!
+MTheCarspotter It's nice game, but i still think the steering could be better. Because for little corrections/turn-in it does feel a bit slow to turn and then straigthen out again. Still far better than the last one. With a bit better steering and a little bit more detail to performance-tuning i think it'd be almost perfect.
that one about not buying 1st year production is rather wise. i had two brand new audi A6s in 2014 both the new model neither worked and both eventually went back to audi. i then had a VW passat in 2015 brand new shape again and same problem. then got a CLS shooting break all worked amazingly and now on an E-class estate again working well
i lease my cars therefor after 2-4 years i get to change. normally i settle for three years with a car and then make up my mind about whether to get the same again or go different. in the case of the CLS id happily go for another one however i got such a good deal on the first one that i couldn't afford the lease on a new one two years later
isnt leasing hell a lot more expenisve then buying the car? u literally pay like.. X-K dollars up front, then pay like.. X dollars each month (for example if u got a 3 yr leasing agreement) until u have payed off the "total" X-K dollars. But then u gotta give the car back to the leasing company after u have paid off the car in split payments for 3 years? if u own the car u can sell it again atleast and get some money back.
Pennzoil 10w30 (not synthetic or high mileage), federated oil filters (upholds new car warranties), 3-5kmi oil changes and boom: 322,000 miles on a still factory sealed motor... And its a dodge magnum 3.9l v6/auto in a 4100lb dodge dakota.
Ford could do something cool with their old Thunderbird name. Make it a large, but sporty electric car that can hit 60 mph in under 4 seconds and sell it for around 50K. It'd probably sell quite well if they can market it like a cheaper, but better handling Tesla.
Point 2: Colder fuel is in fact more dense, so more mass per volume means, that you get more energy for your money. But you're right about the tanks, they do not vary a lot in temperature. In Austria gas stations are only allowed to increase the price of the fuel at noon, so filling up in the morning will probably be cheaper in the morning then in the same days afternoon.
It adds up, it's not like you will be using double the normal amount of fuel but you notice how people will avoid certain places because the fuel is a few cents more expensive? Same thing, if you have it on all the time you may be paying a few dollars extra every time you go for fuel.
say you're averaging 25 MPG. (That's what I average in my corolla) if you run the a/c it's going to bring you down to 22. Over the course of a year that will likely translate to 200+ dollars of extra fuel, assuming you drive 15k a year or so.
Thats what i like about the toyota hybrids, the AC is all electric and supplied through the inverter, the electric compressor doesnt affect consumption or power as much as in normal cars. Whats funny with the toyota hybrids is that if u dont use AC at warm days, it can/will have a negative impact on the hybrid system, consumption and power. Since the hybrid battery needs to be cooled.
But it's not a myth. What is a myth is the need to buy it. You can use piss instead. The enzymes in urine are aggregated by the electrical wiring in bulb like housings (they're not actually bulbs but they retain they're name since they look like bulbs,)causing them to light up and shine. With newer cars you'll need a fleshlight adaptor because the led bulbs need different enzymes for the white shine. You can get away with piss but the lights will flicker. Or just buy the expensive blinker fluid.
Sorry but what cars don't get faster when in overdrive? Have you ever tried that? Which ones? Can you name one honestly? And i certainly hope you grasp how an AC compressor works and that driving down the road with a parachute is less efficient than doing so without a parachute.
+Colton Bartels Yeah seriously. He probably thinks driving with high pressure tires doesn't save any fuel. He probably thinks driving with more toe-in than factory specifications doesn't wear tires any more than at factory specs. He probably thinks pulling up on an e brake without pressing the button ruins it. I've never seen anything like it.
A car only goes as fast as your right foot allows it to. Your mph is your mph regardless of what gear you are in. What matters with overdrive is that more power is needed for acceleration than for holding a steady speed. That's why when you accelerate you downshift rather than upshift. While going higher in gear allows the tires to rotate faster at a given rpm, it also reduces the power available to handle an increasing load. A car in overdrive eventually reaches a point where despite having some rpm to go, the engine simply cannot exert the force needed to increase rotational speed. Due to this limitation, the video is actually correct. Overdrive is to use less power to maintain a steady speed. Just look up what torque multiplication happens with lower gearing ( underdrive), and expect the opposite with overdrive.
Believe me i understand how gears work. I learned in a manual, i only drive manual, and i rebuild transmissions. My mom's minivan reaches 98mph in 1:1 gear. Shift to 4th gear and it'll go 110 before wind resistance limits it there. Please tell me you can grasp that.
Why is there still debate on A.C and fuel consumption? A.C uses power to operate and in a car the power comes from fuel. If you use A.C it affects your fuel consumption, that's is! Basic physics!
Some cars take a noticeable hit on performance when AC is on, so maybe the loss of performance or retarding of engine timing negates the extra fuel consumption. Just a theory that some car manufacturers might be doing that.
Ben Not to be rude but that has to be the most ridiculous explanation I have heard. The internal combustion engine drives electrical generator directly through it's mechanical power provided by the fuel. As the AC-unit draws more power when it's under load, either the engine has to rev up to provide more power to the AC which consumes more fuel, or when the engine is already under heavy load some of it's mechanical power used to drive the car forward is converted to electrical energy to supply the AC thus making it feels like the car is losing its power. But in reality the engine always produce the same amount of power regardless of whither or not the AC is on. Only acceleration of the car is affected when some of the mechanical energy is divided into moving the car and supplementing the AC, making it less efficient at driving the car forward, in turn higher fuel consumption because you need to provide more fuel to the engine to get the same amount of forward momentum.
Ben to make it simple to understand, you can think of the generator as a second smaller engine. If both are to be powered at 100% they will require more fuel. If a pre-defined amount of fuel is used, then the two engines will have to share fuel, thus the bigger one which drives the car forward will get less than the total amount of fuel given. Making it less powerful, in turn if only viewing from the moving car forward point of view, less efficient.
An oil and filter change is easy money though not making much, working at a garage myself though 3000 mile changes are worth doing on performance engines with Forged internals with high spec power. Power oil filters should be changed every 7000 on a normal car due to them crumbling and could clog the oil feeds and cause lots of problems, but if people research these simple not costly things it could save them lots of money in the future.
I'm a mechanic, have been for 5 years and currently Forged my VXR... changing of engine oil DOES benefit your engine greatly every 3000 miles, as specially if the car has a paper oil filter as they have a tendency to bend and could break causing it to get sucked round blocking the pick up etc in bad cases. Long life servicing (20k) is pushing the engine to its limit as stated by dealers themselves, more frequent the better.
The point he was making is still correct: Follow the manufacturer's suggested maintenance schedule, not the recommendations of your local lube technician. If the MFR says you should be changing every 5,000 miles, then do that. That is, of course, if you use the recommended oil. Most manufacturers have two different schedules now: One for "normal" driving conditions and another for "hard" driving conditions. Each of these schedules will have different service intervals.
turning A/C on definitely effects fuel consumption, the engine has to turn the condenser which takes away HP so unless you drive considerably slower then you would with the A/C off you are going to use more fuel.
No. 1 - ALL MOBILE PHONES HAVE ANTENNAS. SMH. No mobile phone has ever generated sparks from its antenna. The reason that there were fires at bowsers is because people would re-enter their car to grab their phone whilst refuelling and build up a static charge in the process. No. 2 - Some components of petrol are more volatile than others. The volatiles have the potential to evaporate out first. That's why old fuel is bad. Yes, tanks at petrol stations tend to maintain a constant temp, but during a heatwave, the fuel will eventually experience a temperature increase. Petrol has a fixed energy content per unit of volume. More fuel = more energy content. No. 3 - Overdrive barely makes a difference to efficiency. Engines consume fuel in accordance with the load that's present. If it takes 11hp to do 60MPH then gearing is irrelevant. X amount of fuel will have to be burnt to deliver that 11HP. You get marginally less friction/heat losses at lower engine speeds, but the difference could be measured in cents per tank. If it has the power available, overdrive does make a car faster. No. 4 - Big difference between synthetic and non-synthetic oils. Yes, synthetics do last longer. If I were running dino oil, I'd be changing every 3000 miles as well.
Petrol has a fixed (chemical) energy content per unit of mass, not volume. If the fuel is heated from around 15°C to 30°C when it is put in the car on a hot summer day it will expand but still provide the same energy to the engine. Overdrive was implemented to go easy on the engine. It is designed for cruising when there are only few load changes. The maximum speed will generally decrease but fuel consumption, noise and wear on the engine, too. Modern cars mostly don't need an extra overdrive because they have at least one gear with a higher transmission rate. Fuel consumption and effective horsepower applied to the movement to the car are not linear by far. Not only due to friction and heat losses. So the potential fuel saving due to different transmissions are huge.
Myth #9 - The Chevy Nova had to be given a different name in Spanish speaking countries because "No va" means "No go", and implies the car doesn't run or go. While yes, the Nova was called the "Chevrolet Chevy" in Central and South American markets, there was really no greater meaning behind it, just as many other cars have different names in different markets (Nissan 350Z is Nissan Fairlady in Japan, Toyota Tacoma is Toyota Hilux in Europe). It's actually ridiculous if you think about it. For a Spanish speaking person to think a car called "Nova" doesn't run because "No va" means no go, would be like an English speaking person thinking a dining room set with the brand name "Notable" doesn't come with a table (as in "no table").

Number 7 is wrong. Still to this day, you have (atleast) one company " FCA " that has a major history of screwing up first year production models. Jeep, Dodge, Chrysler, all three have this problem. You haven't the slightest idea how bad it is until you do your research or happen to own multiple first year model productions...
Now I agree with most of these but theirs two that I don't agree with and one that is just false. For the one I don't agree with is the first generation rule. It is true that modern cars are getting better with their first generation vehicles but when a vehicle goes to a new generation or is a brand new production vehicle their will always be quirks that will be fixed in a year or two it's just a fact that people will discover things that need to be addressed and the company will fix the problems to try and sell more vehicles. As for the one that's false is the oil change rule. I'm a mechanic and I went to school to become a mechanic. It's just basic knoledge that as you drive more you very slowly start to break down the molecules inside the oil and the viscosity of the oil begins to get worse as well as tiny micro fragments of metal from the block gets into the oil and will start to create micro and hair line scaring on the engine. Now while you don't necessarily need to change the oil every 3000 miles it will most definitely help and be better than waiting a little longer say 5-10k miles to change the oil.
Bro every oil has a viscosity type as you can see... These numbers are not fun anyway. As for the scratches, WTF? If you use half or full synthetic there will be no be any scratches. As the myth to use a engine cleaner that was destroyed cause the synthetic ----> 5W30 5W40 10W40 10W30 oils are like cleaner. If you dont clean your hands after a oil change the skin will be damaged by the acid oil structure. As for the change of oil. No need a school for that. If you look closer and use the number from the oil box you can find some info. My car runs on 5W-40 Castrol Full Synthetic. So my next oil change is 10000-15000 km. But every time you should check your oil situation in your engine. Thats it. I dont know where is told to change oil after 3000 miles but i do think this can be only in America. I dont think bad about it but i have no idea what cars are driving in USA but the are all runnning on 0W-30 oil.
The first year rule can backfire very badly. Some cars actually got worse with facelifts and changes, in fact quite a few of them. It's pretty common to lower the quality of a car throughout it's production in order to reduce it's price
Not only does the dyno oil and syntho oil break down, don't forget the rest of it. The engines create carbon, condensation, and other particles from combustion that gets past the rings. All of this stuff gets in the oil and it scratches the cylinder walls and damages the pistons and rings and wears down your bearings as well. Only way to get rid of it is to change your oil and filter every 3000 miles. You can't get around it, it has to be changed regularly. And unless you are racing or towing heavy loads in a truck, syntho oil is just a waste of money. It only resist heat and break down slightly more than dyno oil.
So the oil myth is sort of true. Older oils were not as good as today's oils in terms of breakdown. Also, engines internal parts these days are also coated with some type of PTFE or teflon coating to aid in lubricity at cold engine starts and in high RPM situations. Also, since engines have become more sophisticated with that of variable cam timing, VTEC, etc, there are much smaller oil galleys and passage ways that require a bit better oil and thinner oil to boot. I guess you could say that one myth is that thicker oil is better than thinner oil, which is 100% not true. This all again depends on the application. Oil is so good these days that even at the 3000 mark it may just look to be bad. But analysis test show the oil to be barely used. And at the 8000 mile mark, the oil was starting to show some wear and a bit more ppm of certain metals like copper and zinc. Most cars can go easily 5000 to 10000 mile oil change intervals. Just use a decent base 3 or base 4 oil and don't forget to check the oil level unless you have a dummy light for that. Cheers!
And here's how internet shit starts, by people like Kris posting completely wrong information. Engines are NOT coated with PTFE or any other coatings. Oil galleys have nothing to do with viscosity; engines are engineered to used lighter oil because lighter oil decreases parasitic losses - i.e. better fuel economy and less pollution.
I’m not a mechanic Not a science man either, But I’ve seen cars with, 5-8 k oil changes And I’ve seen cars with 10-20k oil changes (manufactures specified service times) Can you guess what engine looks cleaner?
No, dealerships and garages recommend that so they can make more money of it, most modern cars with modern oil need it every 30.000km or 18000 miles or every year if you don't drive that on a year
My 2012 Ford F150 is every 10,000 miles, and that was set at the factory when the truck had synthetic blend. I use full synthetic, so I probably could go further. Actually, I heard that the oil can go for over 10,000 miles (conventional oil) if you can change only the oil filter. Not sure if that's true, though.
It's NOT a myth to change the oil every 3,000... not if ( and a lot of people do this ) , you drive nothing but in town driving, with tons of cold starts, and improper ( too short ) warm ups, and zillions of short trips where the car never gets fully warmed up.... all conspire to ruin the oil prematurely. Changing every 3,000 only is wrong if you drive nothing but freeway/highway miles all the time, which is easy on the vehicle. So , replace the 3,000 myth with the 'cold' air intake myth, and you still have 8 myths, Mr. Viral Videos.
Changed the oil on my 2002 Dodge Neon every 5k using synthetic and it lasted me 353k miles before I got rid of it, still running. 3k is a myth by oil companies and garages.
Regarding windows and MPG, the Mythbusters actually did something on it, and they determined that the effect is minor (just like with air conditioning) and that if you really are willing to obsess over those few ounces you're saving/wasting, it depends on your speed. Below 55mph, turning off the AC and opening the windows will save you just a tiny bit of gas, while it's just slightly better to close the windows and turn on the AC when at or above 55mph. They also busted the myth that driving a truck with the tailgate down saves gas. It actually _hurts_ your fuel economy slightly. When the tailgate is up and at highway speeds, an eddy current forms in the bed that streamlines the truck. This eddy current can't form when the tailgate is down, and as a result air rushes directly into the truck bed.
@@JonnyD3ath Sure he meant that. Maybe. But if you don't say what you mean, you come across as though you don't know what you're saying. That's what happened here.
Here's another Myth: "Removing the Spare Tire Boosts MPGs". I busted that myth myself with my 2001 Acura MDX. It came with a doughnut spare hung from a cable under the rear of the vehicle. With it there, I got 24 MPG (I'm on the highway most of the time). I removed the doughnut, and my MPGs didn't get any higher. I went to a junkyard and bought a matching full size spare and put it where the doughnut used to be, and my MPG STILL didn't change! My gas mileage increased when I changed the air cabin filter, cleaned the mass airflow censor and throttle cable, and I then put Goodyear Assurance Fuel-Max tires on the car, boosting my MPGs to 28 MPG!
Here in Brazil, you do have to change your oil every 5000 km (around 3000 miles) due to warmer temperatures and lower quality oil. In 5000 km my father's car evaporated (not burned) 2 liters of it's 5 liters of synthetic oil, and the low oil pressure light came on while cornering.
Actually changing engine oil every 3000 miles will prolong your engine life and maintains performance especially on turbo engines,on a NA engines just use cooking oil
If you have a manual shift, "hanging your hand on" the shifter while waiting really does cause wear on the "throw-out bearing" of the clutch. Many people ignore this. (Sorry, this is not a myth, but a fact I'd like to toss in....)
You mixed it up a bit, throwout bearing suffers if you rest your foot on the clutch. Shifting forks gets damaged if you rest your hand on the shifter. Holding a finger or just holding the shifter before shifting doesnt count, but using it as an armrest (physically pushing it) does.
You're totally right! Sorry about that! I meant that hanging your hand on the shift lever wears the SYNCHRONIZER, not the throw-out bearing. So embarrassed. We had a 1946 cab-over Chevrolet truck (inline-6, updraft carb, pedal-start, vacuum-op wipers, etc) that you had to "double clutch" it to shift, in order to manage the shaft speed. You had to do the clutch and then let off the gas and then pop the clutch out again to slow down the shaft to smoothly enter the next gear. This was because the first and second gear synchronizers were worn out and wouldn't adjust the shaft speed to shift. (My Dad said that the lowest gear wasn't "first" gear, but "creeper" gear. Interesting, and WOW I miss that thing!)
Ray Chang No worries, that truck sounds fun, yeah, first gears are also called crawler gears, for easier starts uphill when loaded or offroad. Sold the truck?
That one is true. When you first start your engine the oil is thick and as it heats up it thins out and can do a better job of traveling through all the little venturis in the engine. Also OBD2 cars do have a close loop and open loop cycle i dont remember which is which but when you first start a car from dead cold it will run the engine off a base tune and after it reaches operating temp it will switch to a adjustable tune based on sensor inputs to improve economy and emissions by leaning out fuel if its running to rich adjusting for altitude etc
Engines work best at operating temperature (around 80C). When cold everything is wrong in the engine (thick oil, larger gaps between metal parts etc.) You will notice engines idle higher when cold to make up for all the differences. You should take it easy on a cold engine to avoid premature wear
The petrol station story about the petrol expanding during hot times made me laugh. i heard of it a while back and i thought thats impossible straight away because the machine still counts the same amount of petrol reguardless how much is in the storage vessel.
You missed the whole point of the myth. The idea is that the fuel is denser at lower temperatures, so you fuel up in the morning believing that the tank temp fluctuates throughout the day. If there was say a 10 degree temp difference between day and night then after the fuel has heated up it would expand. The pump measures volume not density.
mechanics sell 3k oil changes to make more money lol what a load. your mechanic doesn't make much money on oil changes and likely does it as a convenience service for you, the real money is made in repair and other service work like timing belt jobs. all the modern tech in the world doesn't change oil contamination from combustion byproducts, the manufacturer lists a service interval that is meant to get you through warranty. also a/c is a PTO device, in other words it requires energy to operate. how much energy depends on the system size and load (how hot and humid it is that day).
They still charge for an oil change service, and oil as a product, so they still make a profit there. But then they add more on top of that, of course.
I agree that you should avoid first year vehicles. I know that Volkswagen's Atlas first year release has up to 8 recalls already. I know some if not most first year model vehicles regardless of brand are okay, but it cannot be called a myth because the evidence is still there. Just my opinion. Great video! Keep up the good work.
Myth 2- you are getting it wrong, the fuel will be denser in morning because it is colder, which means more mass is packed per volume. That is just basic physics, matter usually gets denser as it cools down.
No you are wrong Arun. First, since you can't understand English, I'll repeat what the video says: Gas is stored underground, and due to the insulating effect of the ground and the large mass of the fuel, it stays at a fairly consistent temperature. Also, modern gas pumps are temperature compensated and pump the same volume regardless of the temperature of the fuel.
It is pretty dumb. But I was once at a gas station, checking a voice mail when an elderly man who refuelled his car next to me said: "Do you want us all to blow up?" In another occasion , it was the shop assistant. It is a myth stuck deep in the heads of people.
Viral Vehicles the sign is simply there to tell you not to use the phone and just have your attention on what your doing while filling up your vehicle after all it makes sense cause you are dealing with some pretty flameable/dangerous stuff right? But yeah there is still people that thinks its because of the blowing everyting up story which has absolutly no valid 👎 There is an mythbusters episode where they are testing exactly this myth and there is nothing to it at all 😉
You are. The ac uses engine power. Cars on average will get about 1-2 mpg less with the ac on, and on average above 55 you're mpg will start to suffer with your windows down
The MythBusters actually tested the open windows vs AC. They found that at speeds below roughly 50 miles per hour the open windows were more fuel efficient, but at speeds higher than that the AC was more fuel efficient. Objectively though, in either case the air conditioning is better at cooling you off.

Turning off AC adds more power to the engine. TRUE
AC gobbles up 5-10hp, turn off the AC on a hot day climbing up a hill and you will notice a big bump in torque requiring less throttle input. I use the AC even when cold out to help with hold back descending hills in a lower gear...it drags that much.

Number 7 avoid first year of a car's production used to be true in the past but now due to Federal Regulations every subsequent year has to suck just as bad as that initial year
He mentioned it already
The A/C does rob some fuel mileage due to the extra load it puts on the motor to spin the compressor....
Only under 55 mph, you should add that in. Having the windows down at 55 makes the car much less aerodynamic resulting in the engine working harder to keep the car at 55 than if the A/C was on.
Exactly. Mythbusters tested this years ago. I believe in their tests AC was more fuel efficient from 30 mph. I guess it depends on the aerodynamics of a particular car.
I have a funny myth that some idiots believe: A loud exhaust means a powerful car
Alex Murphy well increasing your airflow can/will increase your power output, though it depends on the car and the exhaust just how much of a difference it makes, and often bigger aftermarket exhausts are louder. However they don't necessarily make a car powerful you are right.
LoneW0lf11 I'm taking about Ricers who do that to their honda econoboxes
Alex Murphy tue
Alex Murphy When a car sounds "good" not loud but good its already faster 😁
Louder exhaust CAN mean better fuel economy and engine performance due to lack of exhaust flow resistance.
The difference only occurs with a properly installed performance exhaust system, though.
3:43 - If you drive an auto, DON'T hold the gear shifter. You look like a fool.
Actually, don't do it in a manual either. It wears out the gears.
no it dont, clutches, gears, steering wheels all have a deadplay where they do nothing. as long as you dont go over that deadplay you can keep your feet on the clutch or your hand on the gearstick... just an other urban legend
press f to doubt. you wear out the shift forks because there is only a certain amount of clearnace and no designed deadplay into a manual trans shifter.
There is a reason nuetral can be engaged on a auto whilst the car moves, only saves fuel when coming down a mountain but it does save alot and only engage drive when car stationary or at low speeds

That myth came from a Family Guy episode.
way way before Family Guy was even thought about.
I attended fueling school in the military and I can give you some advice on when not to fuel up at the station. If the fuel petrol truck just finished unloading than I suggest you get to another fuel station. The reason for this is when the new fuel comes into contact with the old fuel, it all mixes together and the water and dirt particles that separated from the fuel at the bottom of the tank are now mixed back in. If you're super anal about the fuel than I suggest you learn when the fuel truck makes its rounds. Have a few parts per million is not that bad. Either way, I hope this helped.
Huels is right. Even the petrol staff would recommend letting at least 2 hours pass before refuelling every after the delivery.
Not true at all. Modern fuel pump dispensers have a filtration system to reduce if not eliminate particulate matter. Dirt and sediment is almost non existent since storage devices are cleaned regularly.
Sorry to revive an old thread but just like in the military the gas stations have filters too.
Because we all know that every gas station changes those filters every 8,000 gallons.....sorry, worked at one, and not only was "water seepage" a norm, but so was changing the filter 90,000 gallons after its effective filtration life. gas stations are NOT the military Oscar!
You can never trust gas stations, so this one is certainly true. But a "fueling school"? Whoever heard of such a thing?
The Mythbusters showed that the you get the best gas mileage with the windows closed and A/C off, middling gas mileage with the windows open, and appalling gas mileage with the A/C on
Speed also is a factor. At lower speeds around town, windows down and A/C off is better. At motorway speeds (80 kph or over) windows up and A/C on is better.

You have to consider How severe is your driving. Heavy traffic, dusty roads are considered as severe conditions. Highway Miles are not. So, If you drive only on the city and your car's manual says 10k , change the oil at 5k.
I actually change my oil at 7k km, dont know how much miles that translates to
@@buxadonoff my manual says it should be done at 30.000 km (~18.500 miles), which is ludicrous. I change the oil every 10.000 km.

There is a Heat exchanger that is coupled to the normal a/c (So hot/cold not temperature and stuff) if your radiator is clogged and your engine is overheating putting the AC on full heat and full blow will cool it off.

PSA useless additional info. Most fuelling browser fires are caused by women.
Now before you all come round to my place and string me up by the short and curlies, there is a reason why this is. Two actually.
1) Women are more likely to be wearing synthetic fibre clothing. (results in more static)
2) Women tend to use the auto fill more and so do not remain grounded to the nozzle while filling the car. (once again resulting in more static)
Thus they have a greater chance to have a static discharge occur.
4:47 Quirks and features.
As for the first year thing its still true. There is known to have many issues that dont come to light until the car is been in use. So i would 100% never buy a first model year.
Your right I haul loads in to these manufacturers and seen it first hand
AC definitely increases fuel consumption...not by a lot ofc. I would say about 5% to even 10%.
True, the AC motor draws power off the engine. Not only does it increase fuel consumption but it uses horsepower. I know this through doing gas mileage checks. I still think it is worth the extra fuel to stay cool though.
It all really depends on the engine. A 500 hp V8 is really not going to notice the
depends on the car. Just comparing similar era cars: I had a 1994 Toyota Corolla. Using the AC didn't seem to affect the power or MPG much. MY 1993 Subaru Impreza is another story. Turning on the ac dropped MPG by 5 and it was noticeably more sluggish while accelerating.
BlitzkriegRap that's a fuck load mate. 5-10% more fuel just from A/C is absolutely massive. BTW it's not like that at all. A/C affects low capacity, low torque engines more than bigger engines. The more capacity you have the less the a/c will leech your power, and the less you'll have to put your foot down and burn more fuel. A/c alone does not burn any more fuel. Your right foot does when your little Honda civic can't get up a hill with the a/c on.
Myth busters tested this, it's all about average speeds. When you average ~>40mph having your windows down makes a bigger aerodynamic drag on the car than having the A/C on.
actually. Mythbusters PROVED the last one. Driving with the windows down does have an effect on mpg because cars due to the extra drag. The effect is more significant in newer cars rather than older ones. A/C also has an impact on mpg.
Which one of the two is worse depended on the speed you are going, the faster you are driving the worse windows down is.
I am not an expert, but going faster means less air can go inside due to aerodynamics, I think. So the faster you go, the less it should affect. (I'm half an engineer, but haven't gone this deep into physics)
im not sure of the exact reason, but if I had to guess its because the faster you are going the more air you have to push through. I have taken some physics courses but none are deep enough to be able to answer it scientifically.
A more general way of explaining it though is if you do drive with the windows down, at high speeds you can feel more air hitting you while you are riding inside the car.
@@iandms1160 yea, I found the answer below, it does increase drag. Now I am curious if those wind deflectors found on some cars are actually reducing drag with open window, but I don't think anyone ever tested it.
I think from my experience, that meybe if u put vent on 1 and only slightly open back window (2 cm aprox.) u let air flow thru the car interior free and dont get drag from air entering thru vent intakte and building pressure in airfilter and car interior
But, opened windows and increased fuel consumption depends on how big engine u have and how fast u go. On 3 Liter Diesel under 100 km/h u dont See diference, but whith 1 Liter petrol engine speeding 130 km/h whith opened Windows wil increase consumption meybe even 30 percent

Hmm. VW group stuff being unreliable?
Nathan Guthrie why do you even change your car so often?
i lease my cars therefor after 2-4 years i get to change. normally i settle for three years with a car and then make up my mind about whether to get the same again or go different. in the case of the CLS id happily go for another one however i got such a good deal on the first one that i couldn't afford the lease on a new one two years later
isnt leasing hell a lot more expenisve then buying the car? u literally pay like.. X-K dollars up front, then pay like.. X dollars each month (for example if u got a 3 yr leasing agreement) until u have payed off the "total" X-K dollars. But then u gotta give the car back to the leasing company after u have paid off the car in split payments for 3 years? if u own the car u can sell it again atleast and get some money back.
basically by leasing you only pay for the depreciation of the car so you can get more car for the same money

Point 2: Colder fuel is in fact more dense, so more mass per volume means, that you get more energy for your money. But you're right about the tanks, they do not vary a lot in temperature.
In Austria gas stations are only allowed to increase the price of the fuel at noon, so filling up in the morning will probably be cheaper in the morning then in the same days afternoon.

AC doesn't affect fuel consumption?? My whole life has been a god damn lie.
ac does affect ur fuel consumption, but having your windows open affects it a lot less
it does affect fuel consumption, and quite significantly in my opinion. about 10% i my 12 corolla
It adds up, it's not like you will be using double the normal amount of fuel but you notice how people will avoid certain places because the fuel is a few cents more expensive? Same thing, if you have it on all the time you may be paying a few dollars extra every time you go for fuel.
say you're averaging 25 MPG. (That's what I average in my corolla) if you run the a/c it's going to bring you down to 22. Over the course of a year that will likely translate to 200+ dollars of extra fuel, assuming you drive 15k a year or so.
Thats what i like about the toyota hybrids, the AC is all electric and supplied through the inverter, the electric compressor doesnt affect consumption or power as much as in normal cars. Whats funny with the toyota hybrids is that if u dont use AC at warm days, it can/will have a negative impact on the hybrid system, consumption and power. Since the hybrid battery needs to be cooled.
The thumbnail out of context is comedy gold, it has the same energy of "Please do not the cat"
I believe that the fuel economy leaving the windows down doesn't change that much but at higher speed where aerodynamics are more effective

this guy calls minor factors "myths" lol
+Colton Bartels Yeah seriously. He probably thinks driving with high pressure tires doesn't save any fuel. He probably thinks driving with more toe-in than factory specifications doesn't wear tires any more than at factory specs. He probably thinks pulling up on an e brake without pressing the button ruins it. I've never seen anything like it.
A car only goes as fast as your right foot allows it to. Your mph is your mph regardless of what gear you are in. What matters with overdrive is that more power is needed for acceleration than for holding a steady speed. That's why when you accelerate you downshift rather than upshift. While going higher in gear allows the tires to rotate faster at a given rpm, it also reduces the power available to handle an increasing load. A car in overdrive eventually reaches a point where despite having some rpm to go, the engine simply cannot exert the force needed to increase rotational speed. Due to this limitation, the video is actually correct. Overdrive is to use less power to maintain a steady speed. Just look up what torque multiplication happens with lower gearing ( underdrive), and expect the opposite with overdrive.
Believe me i understand how gears work. I learned in a manual, i only drive manual, and i rebuild transmissions.
My mom's minivan reaches 98mph in 1:1 gear. Shift to 4th gear and it'll go 110 before wind resistance limits it there.
Please tell me you can grasp that.
a manual car with under 100hp will usually go faster in the lowest positive ratio gear than in overdrive
Doug demuro following me everywhere!
Why is there still debate on A.C and fuel consumption? A.C uses power to operate and in a car the power comes from fuel. If you use A.C it affects your fuel consumption, that's is! Basic physics!
Some cars take a noticeable hit on performance when AC is on, so maybe the loss of performance or retarding of engine timing negates the extra fuel consumption. Just a theory that some car manufacturers might be doing that.
Ben Not to be rude but that has to be the most ridiculous explanation I have heard. The internal combustion engine drives electrical generator directly through it's mechanical power provided by the fuel. As the AC-unit draws more power when it's under load, either the engine has to rev up to provide more power to the AC which consumes more fuel, or when the engine is already under heavy load some of it's mechanical power used to drive the car forward is converted to electrical energy to supply the AC thus making it feels like the car is losing its power. But in reality the engine always produce the same amount of power regardless of whither or not the AC is on. Only acceleration of the car is affected when some of the mechanical energy is divided into moving the car and supplementing the AC, making it less efficient at driving the car forward, in turn higher fuel consumption because you need to provide more fuel to the engine to get the same amount of forward momentum.
Ben to make it simple to understand, you can think of the generator as a second smaller engine. If both are to be powered at 100% they will require more fuel. If a pre-defined amount of fuel is used, then the two engines will have to share fuel, thus the bigger one which drives the car forward will get less than the total amount of fuel given. Making it less powerful, in turn if only viewing from the moving car forward point of view, less efficient.
Carliz the faster you go the less it effects the fuel consumption.
Carliz is right. AC usage will definitely lessen the car's MPG
An oil change alone isn't worth a mechanics time. I doubt they made that rumour up to make money.
Nyxteros very lucrative lie
I was thinking the same thing. The average person lazily buys oil at the gas station and does it himself. Not sure how the mechanic benefits.
many people dont do their own oil change for various reasons, and its for those oil change places
An oil and filter change is easy money though not making much, working at a garage myself though 3000 mile changes are worth doing on performance engines with Forged internals with high spec power. Power oil filters should be changed every 7000 on a normal car due to them crumbling and could clog the oil feeds and cause lots of problems, but if people research these simple not costly things it could save them lots of money in the future.
To the mechanics oil changes might not be worth it, but the lube shop owners and oil suppliers sure push the 3000 mile rule.
I'm a mechanic, have been for 5 years and currently Forged my VXR... changing of engine oil DOES benefit your engine greatly every 3000 miles, as specially if the car has a paper oil filter as they have a tendency to bend and could break causing it to get sucked round blocking the pick up etc in bad cases. Long life servicing (20k) is pushing the engine to its limit as stated by dealers themselves, more frequent the better.
The point he was making is still correct: Follow the manufacturer's suggested maintenance schedule, not the recommendations of your local lube technician. If the MFR says you should be changing every 5,000 miles, then do that. That is, of course, if you use the recommended oil.
Most manufacturers have two different schedules now: One for "normal" driving conditions and another for "hard" driving conditions. Each of these schedules will have different service intervals.
4:48 it's DEMURO!
Jeruelle Apigo i watch demuro also man, i enjoy them all(Doug Demuro, Viral Vehicles, Car throttle, Chris Fix, and others
I'm a huge fan of his
Marian Voinea yeah
Marian Voinea Car throttle aka. Alex Kersten is an annoying petrol-head. Petrol-heads never respects their cars or other peoples cars
Thorbjørn Madsen WHAT?
i was told cars eat people if you dont drive them properly, I believed it until i was 6.
Haha :O
turning A/C on definitely effects fuel consumption, the engine has to turn the condenser which takes away HP so unless you drive considerably slower then you would with the A/C off you are going to use more fuel.
4:47 I like that you added Doug Demuro there! XD
No. 1 - ALL MOBILE PHONES HAVE ANTENNAS. SMH. No mobile phone has ever generated sparks from its antenna. The reason that there were fires at bowsers is because people would re-enter their car to grab their phone whilst refuelling and build up a static charge in the process.
No. 2 - Some components of petrol are more volatile than others. The volatiles have the potential to evaporate out first. That's why old fuel is bad. Yes, tanks at petrol stations tend to maintain a constant temp, but during a heatwave, the fuel will eventually experience a temperature increase. Petrol has a fixed energy content per unit of volume. More fuel = more energy content.
No. 3 - Overdrive barely makes a difference to efficiency. Engines consume fuel in accordance with the load that's present. If it takes 11hp to do 60MPH then gearing is irrelevant. X amount of fuel will have to be burnt to deliver that 11HP. You get marginally less friction/heat losses at lower engine speeds, but the difference could be measured in cents per tank. If it has the power available, overdrive does make a car faster.
No. 4 - Big difference between synthetic and non-synthetic oils. Yes, synthetics do last longer. If I were running dino oil, I'd be changing every 3000 miles as well.
i laughed so hard when he talked about sparks coming from the antenna xD
Petrol has a fixed (chemical) energy content per unit of mass, not volume. If the fuel is heated from around 15°C to 30°C when it is put in the car on a hot summer day it will expand but still provide the same energy to the engine.
Overdrive was implemented to go easy on the engine. It is designed for cruising when there are only few load changes. The maximum speed will generally decrease but fuel consumption, noise and wear on the engine, too. Modern cars mostly don't need an extra overdrive because they have at least one gear with a higher transmission rate.
Fuel consumption and effective horsepower applied to the movement to the car are not linear by far. Not only due to friction and heat losses. So the potential fuel saving due to different transmissions are huge.
I’m in Australia and I change my oil every 5000 (3125 miles) and it’s just fine
5000 kms that is
I am in Germany, depending on the car oil is changed around 15,000-40,000 km. So how is 5000 km "just fine". for most engines 20,000 is just fine.
Myth #9 - The Chevy Nova had to be given a different name in Spanish speaking countries because "No va" means "No go", and implies the car doesn't run or go.
While yes, the Nova was called the "Chevrolet Chevy" in Central and South American markets, there was really no greater meaning behind it, just as many other cars have different names in different markets (Nissan 350Z is Nissan Fairlady in Japan, Toyota Tacoma is Toyota Hilux in Europe). It's actually ridiculous if you think about it. For a Spanish speaking person to think a car called "Nova" doesn't run because "No va" means no go, would be like an English speaking person thinking a dining room set with the brand name "Notable" doesn't come with a table (as in "no table").

Gotta love Mr. Quirks and Features
Number 7 is wrong. Still to this day, you have (atleast) one company " FCA " that has a major history of screwing up first year production models. Jeep, Dodge, Chrysler, all three have this problem. You haven't the slightest idea how bad it is until you do your research or happen to own multiple first year model productions...
Nevoexpo fun fact: they also screw up second year production and third and fourth and fifth...
I agree, ALOT of first year production models have issues that end up being corrected later on.
Thanks for your video. How often do you opload?
As much as I can humanly produce videos lol
I’ve seen many people in SUVs pushing for 90 and 100 miles an hour because I’m only going 80 miles an hour
Now I agree with most of these but theirs two that I don't agree with and one that is just false. For the one I don't agree with is the first generation rule. It is true that modern cars are getting better with their first generation vehicles but when a vehicle goes to a new generation or is a brand new production vehicle their will always be quirks that will be fixed in a year or two it's just a fact that people will discover things that need to be addressed and the company will fix the problems to try and sell more vehicles. As for the one that's false is the oil change rule. I'm a mechanic and I went to school to become a mechanic. It's just basic knoledge that as you drive more you very slowly start to break down the molecules inside the oil and the viscosity of the oil begins to get worse as well as tiny micro fragments of metal from the block gets into the oil and will start to create micro and hair line scaring on the engine. Now while you don't necessarily need to change the oil every 3000 miles it will most definitely help and be better than waiting a little longer say 5-10k miles to change the oil.
Bro every oil has a viscosity type as you can see... These numbers are not fun anyway. As for the scratches, WTF? If you use half or full synthetic there will be no be any scratches. As the myth to use a engine cleaner that was destroyed cause the synthetic ----> 5W30 5W40 10W40 10W30 oils are like cleaner. If you dont clean your hands after a oil change the skin will be damaged by the acid oil structure. As for the change of oil. No need a school for that. If you look closer and use the number from the oil box you can find some info. My car runs on 5W-40 Castrol Full Synthetic. So my next oil change is 10000-15000 km. But every time you should check your oil situation in your engine. Thats it. I dont know where is told to change oil after 3000 miles but i do think this can be only in America. I dont think bad about it but i have no idea what cars are driving in USA but the are all runnning on 0W-30 oil.
The first year rule can backfire very badly. Some cars actually got worse with facelifts and changes, in fact quite a few of them. It's pretty common to lower the quality of a car throughout it's production in order to reduce it's price
Not only does the dyno oil and syntho oil break down, don't forget the rest of it. The engines create carbon, condensation, and other particles from combustion that gets past the rings. All of this stuff gets in the oil and it scratches the cylinder walls and damages the pistons and rings and wears down your bearings as well. Only way to get rid of it is to change your oil and filter every 3000 miles. You can't get around it, it has to be changed regularly. And unless you are racing or towing heavy loads in a truck, syntho oil is just a waste of money. It only resist heat and break down slightly more than dyno oil.
First year focus RS had been proven to be unreliable as hell. Lol
Northumberland Post Right. But wrong about synthetic oil. th-cam.com/video/tYkg0oDUXs8/w-d-xo.html
So the oil myth is sort of true. Older oils were not as good as today's oils in terms of breakdown. Also, engines internal parts these days are also coated with some type of PTFE or teflon coating to aid in lubricity at cold engine starts and in high RPM situations. Also, since engines have become more sophisticated with that of variable cam timing, VTEC, etc, there are much smaller oil galleys and passage ways that require a bit better oil and thinner oil to boot.
I guess you could say that one myth is that thicker oil is better than thinner oil, which is 100% not true. This all again depends on the application. Oil is so good these days that even at the 3000 mark it may just look to be bad. But analysis test show the oil to be barely used. And at the 8000 mile mark, the oil was starting to show some wear and a bit more ppm of certain metals like copper and zinc.
Most cars can go easily 5000 to 10000 mile oil change intervals. Just use a decent base 3 or base 4 oil and don't forget to check the oil level unless you have a dummy light for that. Cheers!
Wait Teflon..u say... Heres an idea why not just use Teflon as oil
And here's how internet shit starts, by people like Kris posting completely wrong information. Engines are NOT coated with PTFE or any other coatings. Oil galleys have nothing to do with viscosity; engines are engineered to used lighter oil because lighter oil decreases parasitic losses - i.e. better fuel economy and less pollution.
@@orcajames463 wouldnt a teflon coated internals be a good idea? Or would it wear down to quick?
I’m not a mechanic
Not a science man either,
But I’ve seen cars with,
5-8 k oil changes
And I’ve seen cars with 10-20k oil changes (manufactures specified service times)
Can you guess what engine looks cleaner?
I know because I'm one of those 5k oil change idiots and the inside of my motor is cleaner than the outside

Daddy Doug is everywhere!
Yet Daddy Doug is the the type of guy that makes a video about the quirks of all the quirks he has found over the years.
Actually most manufacturers recommend changing the oil every 3000-5000 miles.
No, dealerships and garages recommend that so they can make more money of it, most modern cars with modern oil need it every 30.000km or 18000 miles or every year if you don't drive that on a year
GM has 30.000 km and Volvo 20.000 km service..
My 2012 Ford F150 is every 10,000 miles, and that was set at the factory when the truck had synthetic blend. I use full synthetic, so I probably could go further.
Actually, I heard that the oil can go for over 10,000 miles (conventional oil) if you can change only the oil filter. Not sure if that's true, though.
[TECHNOLOGIC] go ahead and change your oil ever 18000 miles i dare you
It's NOT a myth to change the oil every 3,000... not if ( and a lot of people do this ) ,
you drive nothing but in town driving, with tons of cold starts, and improper ( too short ) warm ups, and zillions of short trips where the car never gets fully warmed up.... all conspire to ruin the oil prematurely. Changing every 3,000 only is wrong if you drive nothing but freeway/highway miles all the time, which is easy on the vehicle. So , replace the 3,000 myth with the 'cold' air intake myth, and you still have 8 myths, Mr. Viral Videos.
0:27 when you're a little too ready to get in there
3k oil change is not a myth. It sounds like some of these lists are put together by people who have never worked in cars.
icenine135 it isn’t. Some manuals say as long as 15k
you change the oil when its dirty, just drink it and find out
Changed the oil on my 2002 Dodge Neon every 5k using synthetic and it lasted me 353k miles before I got rid of it, still running. 3k is a myth by oil companies and garages.
That Doug reference tho hahaha...also known as quirks in the Doug language
Regarding windows and MPG, the Mythbusters actually did something on it, and they determined that the effect is minor (just like with air conditioning) and that if you really are willing to obsess over those few ounces you're saving/wasting, it depends on your speed. Below 55mph, turning off the AC and opening the windows will save you just a tiny bit of gas, while it's just slightly better to close the windows and turn on the AC when at or above 55mph.
They also busted the myth that driving a truck with the tailgate down saves gas. It actually _hurts_ your fuel economy slightly. When the tailgate is up and at highway speeds, an eddy current forms in the bed that streamlines the truck. This eddy current can't form when the tailgate is down, and as a result air rushes directly into the truck bed.
Mr. Viral, I know you're a BMW owner, so *what* BMW do you own? I have a 2011 128i, great little whip!
I have a 2008 130i lol. Very nice!
I have a Nissan gtr , I want a bmw too :/
Modern mobile phones have antennas too. That’s how they get reception.
He must have meant external antenna
He was talking about old school antennas
We have antenna bands which wrap around the phone. Which is lightyears different.
@@JonnyD3ath Sure he meant that. Maybe. But if you don't say what you mean, you come across as though you don't know what you're saying. That's what happened here.
Here's another Myth: "Removing the Spare Tire Boosts MPGs". I busted that myth myself with my 2001 Acura MDX. It came with a doughnut spare hung from a cable under the rear of the vehicle. With it there, I got 24 MPG (I'm on the highway most of the time). I removed the doughnut, and my MPGs didn't get any higher. I went to a junkyard and bought a matching full size spare and put it where the doughnut used to be, and my MPG STILL didn't change!
My gas mileage increased when I changed the air cabin filter, cleaned the mass airflow censor and throttle cable, and I then put Goodyear Assurance Fuel-Max tires on the car, boosting my MPGs to 28 MPG!
AHAHAHA THAT DOUG DEMURO REFERENCE
change the oil every 3000 miles?
on rx8 and s2000 should
pepe the frog on a rx8 you need to put oil in it every 1000
RX8 is different yeah. lol
Here in Brazil, you do have to change your oil every 5000 km (around 3000 miles) due to warmer temperatures and lower quality oil.
In 5000 km my father's car evaporated (not burned) 2 liters of it's 5 liters of synthetic oil, and the low oil pressure light came on while cornering.
Don't forget the STI LOL
And the Chevy equinox
Wasn't expecting that "Fail lol" to appear on the screen... yeah.. i burst out laughing!

Actually changing engine oil every 3000 miles will prolong your engine life and maintains performance especially on turbo engines,on a NA engines just use cooking oil
😃
If you have a manual shift, "hanging your hand on" the shifter while waiting really does cause wear on the "throw-out bearing" of the clutch. Many people ignore this. (Sorry, this is not a myth, but a fact I'd like to toss in....)
Really? I have done that a few times in traffic
Ray Chang you mean foot on cluch causes wear on bearing
You mixed it up a bit, throwout bearing suffers if you rest your foot on the clutch. Shifting forks gets damaged if you rest your hand on the shifter. Holding a finger or just holding the shifter before shifting doesnt count, but using it as an armrest (physically pushing it) does.
You're totally right! Sorry about that! I meant that hanging your hand on the shift lever wears the SYNCHRONIZER, not the throw-out bearing. So embarrassed.
We had a 1946 cab-over Chevrolet truck (inline-6, updraft carb, pedal-start, vacuum-op wipers, etc) that you had to "double clutch" it to shift, in order to manage the shaft speed. You had to do the clutch and then let off the gas and then pop the clutch out again to slow down the shaft to smoothly enter the next gear. This was because the first and second gear synchronizers were worn out and wouldn't adjust the shaft speed to shift. (My Dad said that the lowest gear wasn't "first" gear, but "creeper" gear. Interesting, and WOW I miss that thing!)
Ray Chang No worries, that truck sounds fun, yeah, first gears are also called crawler gears, for easier starts uphill when loaded or offroad. Sold the truck?

One car myth I herd was hot engines would make the car run better. I never believed it though
That one is true. When you first start your engine the oil is thick and as it heats up it thins out and can do a better job of traveling through all the little venturis in the engine. Also OBD2 cars do have a close loop and open loop cycle i dont remember which is which but when you first start a car from dead cold it will run the engine off a base tune and after it reaches operating temp it will switch to a adjustable tune based on sensor inputs to improve economy and emissions by leaning out fuel if its running to rich adjusting for altitude etc
100% true
Engines work best at operating temperature (around 80C). When cold everything is wrong in the engine (thick oil, larger gaps between metal parts etc.) You will notice engines idle higher when cold to make up for all the differences. You should take it easy on a cold engine to avoid premature wear
Shoulda beleived it. Car engines run best at operating temperature
Not only engine, the whole car starts working better after some time of driving
The petrol station story about the petrol expanding during hot times made me laugh. i heard of it a while back and i thought thats impossible straight away because the machine still counts the same amount of petrol reguardless how much is in the storage vessel.
You missed the whole point of the myth. The idea is that the fuel is denser at lower temperatures, so you fuel up in the morning believing that the tank temp fluctuates throughout the day. If there was say a 10 degree temp difference between day and night then after the fuel has heated up it would expand. The pump measures volume not density.
Lot of bollocks in this video. And misleading.
mechanics sell 3k oil changes to make more money lol what a load. your mechanic doesn't make much money on oil changes and likely does it as a convenience service for you, the real money is made in repair and other service work like timing belt jobs. all the modern tech in the world doesn't change oil contamination from combustion byproducts, the manufacturer lists a service interval that is meant to get you through warranty.
also a/c is a PTO device, in other words it requires energy to operate. how much energy depends on the system size and load (how hot and humid it is that day).
They still charge for an oil change service, and oil as a product, so they still make a profit there. But then they add more on top of that, of course.
I agree that you should avoid first year vehicles. I know that Volkswagen's Atlas first year release has up to 8 recalls already. I know some if not most first year model vehicles regardless of brand are okay, but it cannot be called a myth because the evidence is still there. Just my opinion. Great video! Keep up the good work.
Nobody:
Literally nobody:
12 y.o kid: oMG tHaT CAr iS ON GtA V loL OMg
Bollocks. Overdrive is simply when the gearing makes wheel rpm => engine rpm.
Myth 2- you are getting it wrong, the fuel will be denser in morning because it is colder, which means more mass is packed per volume.
That is just basic physics, matter usually gets denser as it cools down.
No you are wrong Arun. First, since you can't understand English, I'll repeat what the video says: Gas is stored underground, and due to the insulating effect of the ground and the large mass of the fuel, it stays at a fairly consistent temperature. Also, modern gas pumps are temperature compensated and pump the same volume regardless of the temperature of the fuel.
Great video bro🤙🤙
But that first one sounds super dumb😂😂😂
Keep up the awesome content
Lol. There are signs on my local petrol station that say no phones lol
It is pretty dumb. But I was once at a gas station, checking a voice mail when an elderly man who refuelled his car next to me said: "Do you want us all to blow up?"
In another occasion , it was the shop assistant. It is a myth stuck deep in the heads of people.
Viral Vehicles the sign is simply there to tell you not to use the phone and just have your attention on what your doing while filling up your vehicle after all it makes sense cause you are dealing with some pretty flameable/dangerous stuff right?
But yeah there is still people that thinks its because of the blowing everyting up story which has absolutly no valid 👎
There is an mythbusters episode where they are testing exactly this myth and there is nothing to it at all 😉
I also smoke while fueling. It's no problem, because it's just Diesel.
All this time I’ve been sweating in the car thinking I’m saving gas!! 😩
lol
You are. The ac uses engine power. Cars on average will get about 1-2 mpg less with the ac on, and on average above 55 you're mpg will start to suffer with your windows down
Mike Zerker you are
The MythBusters actually tested the open windows vs AC. They found that at speeds below roughly 50 miles per hour the open windows were more fuel efficient, but at speeds higher than that the AC was more fuel efficient. Objectively though, in either case the air conditioning is better at cooling you off.
