I looked up mitsubishi today and it says #6 in reliability brands. So can we get a new honest opinion because Im curious if this myth is true. Because mitsubishi was bad but they're beautiful japanese cars
Just found you Scotty and I’m loving the content. I lost my dad in a car wreck when I was 8 and you are filling the gap of all the knowledge on cars I missed out on. I owe you a few beers. Thanks so much!
He's spot on about super unleaded gas. I have a 2014 Honda Accord 2.4L my kids have named "Dad's Taxi." I switched to regular unleaded from super because of the rising gas prices. I was averaging around 26 mpg (suburban driving) on super and now I'm averaging about 28 mpg on regular and it actually seems to have more pep. 2 mpg may not seem like much, but that's 20 more miles on 10 gallons of gas. That's an extra day of school runs for me.
I never would've thought that would make a difference like that. Figured it would make no difference at all for an engine tuned for 87 like that. Great car too, the final Accord model I liked.
you know in the owners manual it actually tells you what level of octane gas you should be using as thats the gas that was meant for your build of engine
Same for the reverse. I’m supposed to use the high octane gas in mine, but yeah pricey. I’ve lost some horsepower, but my car still has 320 even with that. I’m not driving a bajillion miles an hour. I’m good w the savings.
I once was asked to see if I could figure out why a motorcycle kept having carburetor problems. I ran it until it was out of gas and then the owner told me, "I always put premium in it." I checked what octane it specified and it was low octane. After about a quarter mile of having the correct fuel in it, I had it fixed for her. She was really happy.
Most likely water or somthing else contaminating it or old gas... You can run 100 octane fuel on a motorcycle meant for 92 octane and it will just run like normal. Only the other way around using to low octane causes trouble.
@@a64738 What you just said: "No you're wrong, your experience is invalid because I think I know better than you." He just said he tried to put lower octane in it and it worked better. Not all motorcycles are built equal. :)
In E10 gasoline the ethanol and gasoline can form two different layers therefore cauaing problems in engines with carburetors. The problem is avoided if new gasoline is used or E10 is avoided, also direct injection engines are not affected.
@@Loanshark753 You are quite correct. Ethanol contains Oxygen. As EFI engines have an O2 sensor. The ECU will adjust the mixture automaticity. This is something that an engine with a carb can't do.
I replaced my spark plugs on my Toyota Tacoma recently at 120K miles. They still looked like new! I remember back in the day when we used to have to replace spark plugs every 10K miles because they were shot. The thing about car myths is that many of them were true AT ONE TIME, but not true anymore. People just refuse to believe that things have changed when it comes to doing maintenance on your car.
"I replaced my spark plugs on my Toyota Tacoma recently at 120K miles. They still looked like new!" That does it. Finally I'm convinced not to replace (actually, to have a mechanic replace, because on a V6 engine the back bank is a bear to get at) my 2011 Toyota Venza's sparkplugs. It has 95,000 miles but as little as I drive, 3K miles a year at most, the engine will outlast me. Thanks for the input, BD.
My cousin & I switched my used 2005 P74 Ford Crown Vic V8 4.6L spark plugs, 8x. Bosch double platinum. I expect my plugs to run 30000mi or so. 220000mi.
Imagine sitting in stop-and-go traffic on a hot summer day, with hot-running cars all around, and you've got your windows down instead of using the A/C to try to save a little money. In my early driving days, I didn't have A/C and sitting in traffic on a hot summer day was brutal.
The remote key range doesn't depend on its position relative to your body but rather its orientation. Depending on how the antenna is oriented within the key you simply get a better range holding it upright or in a 90° angle towards the car. With most keys I found holding them upright slightly above your head will already give you maximum range. In a parking lot with all the parked cars of course they're gonna absorb the signal if you "shoot from the hip".
@@CraigGrant-sh3in Of course it also depends on how strong your keys signal is to begin with. Some work across the whole lot, other will require you to have it in sightline.
True. Changing or modifying an antenna cannot give you more power in all directions. It can give you more power in specific directions, but only by causing less power to go in other directions.
As always, Scotty is right on in this video ! But just one thing to remember if you change your oil every 10,000 miles make sure you put a high mileage filter on . If you use a regular filter and you go 10,000 miles the paper starts to break down so make sure you use the correct filter for the higher mileage.
My oil would be sludge by 10000 miles unless my life was solely on the interstate. In fact I have bad luck with 5000 intervals. Like everything else, there's some bad parts floating around and you really gotta be observant. $15 oil filter is not something I'd buy when a $1-3 one lasts a year and 2000 miles.
I am so happy that I found this guy. I have corrected the mistakes that I have made in the past, plus I have more knowledge on how to take care of my car. Thank You and I enjoy your animated style of teaching.
I didn't know about the key fob trick After doing some quick research, it looks like the water is acting as a reflecting surface. In this case, I maybe a paraboloid reflector could be used to really concentrate the key fob's signal in a particular direction.
It works but I get better range if I touch it to the bottom of my jaw bone instead of the throat. It's the curse of owning one of the smallest cars in the parking lot.
Thank for the video 2020 F-150 2.7 liter, I seen on the forums people saying higher octane gas give you better gas mileage so I tried mid grade and found that to be false, I got better mileage with 87 octane, 89 was 60+ cents more per gallon.

Important tip: Just because your spark plugs "still look new" that does not mean they are not worn. They can "look new" AKA "Clean" but still have a worn down electrode. Meaning the Gap between it and the contact is wider then it should be. Change spark plugs according their specs (time, milage, ect) and not so much the car's manufacturer's specs.
Myth Busters also did the same experiment. They tested a modern car with AC & drove it with the AC on, then repeated the test with AC off, & windows down. Driving with windows down increased fuel consumption compared to windows up & AC on.
And there are still some specialist that say "windows open is better". I get it for low city speeds. For me was the best having a roof window tilted, rarely needed the ac, but in combo with ac that was great...warm air under the roof just was pulled out while pushing in cold air in the bottom, and it got cooler.
@@mammutMK2 I don't listen to the so called specialists. They tell you windows open is better, yet actual tests prove otherwise. A properly working a/c system in a car draws bugger all power, especially the rotary compressor types built in the last 30 years. Even my 1976 Mercedes has a rotary a/c compressor from factory, not only this, I'm a retired auto engineer, so I do know what I'm talking about, unlike these "specialists" who just want your extra money for fuel.
I prefer window open to AC. Especially in Tuscan AZ during the day. Had the window open & the AC on. Was burning my left arm & face with the window up.
@@Elizabeth-rq1viwindow open and AC on??? it's one or the other. you leave the AC running while window is open, you are only overloading the AC system.
@@marrionberry8848 with the window up my left arm was getting burned! I don’t live in Tuscan so that was quite the experience! Usually I don’t have the AC on, I’m a window open person unless the car is SO hot! Also to help cool the stifling hot car down we open the windows to let the heat out for a boy 5mins & then close them.
Scotty you educated us on this topic a few years ago. I immediately showed this to my young son then and now shot a video of this on my phone as a helpful reminder and sent it to him. He has learned lots from you (at only 18 yrs old) because I have learned a lot from you. Love your channel and a happy subscriber. However, never trust a mechanic who lives in his trunk......🤣😂
Back in the day all we basically had to do was keep the carburetor clean, occasionally flush out the cooling system, and change the engine oil and transmission fluid. Those old push rod engines were pretty easy to take care of.
Except when it comes to oil change frequency. Just do it every 5k and disregard the computer oil change interval. By the time the damage is done, it's out of warranty and NOT their problem!
Wrong. Accountants rule the bottom line for companies not engineers. They talk about lifetime diff, trans and transaxle fluid (BMW etc) this is false. Their definition of lifetime is different from yours. Oil, I would say do every 5k miles using synthetic, if you do city and highway driving. It's such cheap insurance, you'd be insane not to. My car has 275,000 on it, oil changes every 5k miles with a filter change (Napa/Wix/Fram TG or Ultra)
I find that since I do a lot of highway miles at 70 mph and I use full synthetic, my 150,000 mile 2010 Toyota Yaris runs great! I can take a (supposedly) 10,000 mile filter and change it out around 4 to 5 K, which gets new oil introduced into the filter to replace what was taken out, and run another 3-4k before changing it out completely. Having the filter changed often is cheaper than changing the oil outright since much of the work of the filter is to keep the engine clean and oil free to do it's job. On occasion, I will run some MMO in the engine just before a full oil change. We are about to take a trip to Chattanooga from St. Louis in June, as we have made several trips to Atlanta in the past three years with the car.
I used to get oil changes: 4000 5000mi with my used 2002 Jeep Liberty 4x4: 2013 to 2018. Towards the end, now(used Ford P74 Crown Victoria V8, 2005) I get synthetic oil changes. Every 6000mi or so.
Scotty you make amazing videos for people like me who didnt have a parental figure who was any good with cars, or at the very least willing to teach what they know.
Scotty is so right about the EVAP system getting raw gas in it if you overfill your fuel tank. I use to have a habit of doing that years ago when I owned a Chevy Venture van. The last time I filled it up I went home and a few hours later went outside to leave and smelled a very strong odor of gas coming from underneath. Upon inspection I could tell it was in the EVAP system so I took it in and they replaced it and they told me not to overfill the tank but to stop when the automatic shut-off stops pumping gas into the automobile. I've never had any trouble with any other vehicle again by taking that advice.
I bought a used 2014 Navigator and found that when the gas tank is full and the pump shuts off, my gas gauge reads just 3/4 full. The computer shows the full range to be O.K. When the gauge reaches 1/2 full, it then becomes accurate to the computer and it reads fine all the way down to empty. A mechanic told me that the gauge accuracy was probably affected by the previous owner topping off the tank after the pump shuts off. There's no other issues, so I'm not planning to replace the EVAP system to fix it.
Not to mention that just about every gas pump in America says on it "DO NOT TOP OFF". There's a good reason for that, folks! Thanks, Scotty, for putting out there what that reason is!
I just ran a fuel injector cleaner and replaced the coils and spark plugs in my wife’s 2008 matrix. The parts were all original, and you could feel a little rough idle when the car was cold. It couldn’t of been any easier. The car runs as smooth as silk now.
I was worried back when I was about to buy my next car and it would be our first fuel injected one, because what would I do if it needed a tune up? No carburetor. I should not have been concerned. Today’s cars are so much better without carbs!
I have never had to replace a coil. Fuel injector gas additive every 4-6 months and spark plugs per the maintenance schedule keeps my three cars running fine.
I had my Ford P74 2005 V8 Crown Victoria LX spark plugs swap out. I'd agree, replace the ignition coils too. I later had 2 coils replaced: $$$ 😌. Engine parts-components function smoother, better when new. Better MPG ⛽️ too.
About oil change interval. in 2008, I bought a 2004 Ford Focus in California with 58,000 miles on it. With the 2.3L DOHC engine. I changed the oil and filter every 5000 miles, with full synthetic of the recommended viscosity. In 2021 I gave the car away to a friend, with 149,000 miles on it and it still uses no oil between changes. The only engine work, besides the 100,000 mile maintenance was it needed the intake manifold replaced as it had cracked. I got one from a car recycling yard. In 2023 my friend is still driving it. My point is that I concur with your oil change recommendation.
I had an older Dodge Dakota that would not run on 87 octane fuel. It would lose power and knock and ping. I had to use the, at the time, 89 octane fuel and it ran great.
Thanks for the video! 3:22 - hey I have an 2004 Porsche Cayenne v8, it says it needs the high 93 in it. So are you saying it would be find with the regular 87, just that the HP will be lower? 3:34 - what is considered a modern vehicle? 2000 model year+?
I’ve been in the car service business for 30 years and our fuel additive folks took premium, mid grade, and regular fuel and poured 1 tbsp each in a white saucer and lit them. When they burned off, the premium had the most black soot. It burnt dirtier
my 19 F150 with 5.0 would knock and ping like mad if I didn't run 91 octane. It was like getting a raise when I got rid of the POS at 46K miles due to transmission issues. My new truck runs 87 without issue saving about $35 a fill up.
Virtually every used car I’ve ever bought I’ve improved the fuel consumption, acceleration and top speed by just giving it a good old Italian tune up. Most people drive too slow and the engine gets clogged up with carbon etc - use the performance of the car and you will clear all that crap out and the car will run better. Plus check tyre pressures regularly when cold and use top quality oil and filters.
Scotty, average mileage per year here in the UK is 10-12000 miles. I always get my car serviced according to manufacturers instructions... which always includes an oil and filter change every 10-12000 miles.....so what do you think of that? It's a Maza CX-5 2.2 litre diesel, by the way.
Back in 1986 I bought a new Chevy sprint. It has a 1 liter 3 cylinder Suzuki motor. Some people had complained that the motor would shake. Come to find out they had put in premium gas. Chevy put out a bulletin to not use premium gas.
When I first bought my 2015 Silverado 5.3l I tested the different octane to see which one I get better mileage. Each octane test was 300 miles with the AC on. 89 octane got 1 more mile per gallon than 87, and 91.
I did a study on my car to test different grades and gas stations for fuel mileage. Premium didn't make a difference, but brand did. Chevron gave me the best mileage, Arco gave me the worst (i didn't test any brands that weren't on the official top tier list)
Regarding fuel, any thoughts on the running your tank dry vs keeping at least a quarter full. I was always told, and read in the manuals, that you should aim to nit let your tank drop below about a quarter full else all the waxes and impurities in the fuel that normally float near the top of the tank will get sucked through and mess up your engine. My sister refuses to fill her tank more than a quarter full because she says she can’t afford to spend that much on fuel (ignoring that this means she has to get fuel about every 3-4 days, and often has to go to more expensive garages because she doesn’t have enough fuel to get her to a cheaper one, plus in the past when I’ve filled her tank she’s just run it down to below quarter full and will not fill it over about quarter full). And she wonders why she’s getting through a fuel filter every year, has to clean her plugs twice a year and has to replace various sensors every year or two.
Every mechanic I've talked to has said to never let your fuel get below a 1/4 of a tank if you can avoid it. She should instead fill it to half a tank and then refill to only a half tank(once she gets to 1/4) and she would be paying the exact same amount.
In my 2017 Hyundai Elantra, I get about 3 MPG more with the windows down than I do with the A/C on (not even blasting at full power). It has been consistent over 6+ years, all working at the same location and living in the same house (so no adjustments for different driving conditions). My commute is half freeway and half surface streets, a total of 13 miles each way.
Scotty needs to apply to the Royal Academy of Dramatic Art, as he'll definitely get in , due to the incredible arm waving during a very mundane conversation.
I've gone to stations and they were out of regular grade gas, and we're offering high grade for the same price, so I filled up. On both my 2000 and 2014 Civic it actually tripped my Check Engine light. It didnt affect the way it ran, but did turn the light on. On the next fill up of regular, iit went away both times.
I love Scotty’s references to Houston, TX. Everything he says is absolutely true. So funny! Love all the information he so generously provides. I wish he still lived in Houston! ♥️
I've heard about NOT adding any more gaoline once the pump cuts off cause you COULD mess up the gas canitors up I learned that from the late Pat Goss from Moterweek
The one thing you can do to get the maximum mileage over the lifetime is change your oil and filter every 3000 miles with no exceptions. I don't care what your manual says when they tell you every three months either mileage not months. Yes I was a professional mechanic and I drove a 1987 GMC Full Sized Jimmy 315,000 miles until it was wrecked by doing just that with Mobile One synthetic. I pulled the engine and disassembled it to find no appreciable wear anywhere.
To be quite honest we change oil at the prescribed intervals, which are 15 000 kilometers (about 9300 miles) for many Toyota models. For some Skoda models the interval at least used to be 30 000 kilometers (about 19 000 miles). We have never had any problems because of this. Some people actually say that it is even safe to only refill oil, and just change the oil filter about every second year.
Modern engine oils are incredible for long life. 10,000 miles minimum, 16,000 miles comfortably. Designed to last as an environmental friendly thing- avoiding unnecessary legal disposal and illegal dumping via DIY's using household rubbish bins
I drive a Honda CR-V and it tells me when to change my oil! It’s usually around 6 months and around 15,000 miles!!!In years passed we always changed at 3,000 miles! My csr runs perfectly and have never had a single problem. Oh, and my fob needs to be pretty close to my car to work which is fine with me as I really don’t want to unlock it when I’m not even close walking from a store!
@@sandybruce9092 Good for you. Nonetheless, we actually change oil at the recommended intervals, which is about every 9300 miles for a Toyota Yaris. Thus, the question is not if the car runs well, if one changes the oil every 3000 miles. The question is whether it runs just as well when one triples the change interval to about 9000 miles.
@@jonebjrheim3148 Yes, my car runs perfectly - my husband knows cars and he wouldn’t “allow” (I’m using that word euphemistically) me to do this if I was going to make a mess of the engine! At about $100 a pop for an oil change it just isn’t viable for us! And I NEVER go to a dealer! I can work with the salespeople when purchasing - and I’ve been purchasing our cars for over 30 years - but I won’t deal with service people who always want to sell me something just because they think I’m just a stupid female!
One car myth was about pickup trucks with the tailgate up or down. You still see some tailgates with openings in them for air flow. I remember reading about it and with the gate up it actually made the truck more aerodynamic because it created a rolling cell of air in the bed area. Don't know about modern trucks, maybe the difference between 16.5 mpg and 16.8 mpg is not enough to notice.
My 2015 Prius really never required a tune up at all. The manual said to change the spark plugs after 100,000 mi. I didn't because the dealership wanted almost $300 to do it (lots of plastic covers and windshield wiper junk and metal bits to remove just to get to them). I didn't want to take the time to do it myself, because I figured I would take four or five hours to figure out how to do it, even with TH-cam videos. I let the spark plugs go and finally decided to have them replaced by the dealer at 240,000 mi. The dealer price had dropped to about $220 by that time, so I told the dealer to go ahead and do it. The original spark plugs were a nice very light tan color and the gap did not look horrendously wide although I didn't measure it. The car got about 2 MPG better gas mileage after the spark plug change.
Tires are important... wonder why mechanics and body shops never have the same tire to match the others. And end up going back for balance reasons and tire wear down. I always make sure I have the exact same tires.
2:10 I can’t believe Mustang eco-boost loses over 40 hp going from premium to regular fuel. My naturally aspirated GDI Hyundai Genesis V6 would go from 348 hp down to 340 hp according to the owners manual.
0:46 for the remote under the chin trick to work, it's not enough to put it under your chin. It's placed there so that you could make a buzzing sound with your mouth and help amplify the remote's signal(s). Supposedly, anyway.
A local station charges 45 cents more per gallon for 91 octane non-ethanol versus regular 87 with 10%. I get enough better mileage on a full tank of 91 to come out slightly ahead versus using 87, but only at the current price point.
Non ethanol is definitely the way to go however where I am at the only non ethanol is 91 octane with a significant increase in price. I only get about 2 extra mpg which isn't worth the difference. If I had more money to blow then yeah, 91 ethanol free > 87 10% ethanol.
Well basically, if your car loses (horse) power because of no premium fuel, what it essentially needs, it's NOT good and running perfectly fine tho. It runs perfectly fine when it doesn't lose power because of other fuel then recommended. It's not recommended by the manufacturer for fun, they don't get a cent from BP or Shell.
With my newer car, I only "overfill" to the next 25 cents. With my older car, I could easily fill up another dollar in there. It does seem that the modern cars are more "full" when they shut off.
I really mistreated my 2015 Prius that I used almost exclusively for Lyft driving. My oil changes sometimes were 20,000 or 25,000 miles apart. The car has 310,000 miles on it and is still working fine, although my fuel economy has dropped from about 53 MPG when it was new to about 46 MPG. Imagine how long this car would go if I changed the oil every 5 or 10,000 mi.
@@SmokeDogNY420 Yeah, pretty nonsensical. Those Prii do soldier on, though. And all that time, I never had to top up the oil. Every time I checked it was at least half way between FILL and FULL.
@@ichbindarren No. There appears to be no need to do that. That car has nickel metal hydride battery cells in its pack (it's not the plug-in hybrid model, which in later model years are lithium ion). I think the degradation of the NiMH cell is more related to age and temperature cycles than it is to miles driven. In my car, the time it takes to charge the battery enough so that the gas engine turns off is still not much more than when I got the car new.
@@bobbabai change the car battery after the warranty is done. I changed to an AFM in my Toyota Camry Hybrid. The large hybrid battery is for life of the car.
Can you talk about car companies charging to turn On heated seats, which are installed, for a fee? Or they charge for increasing the vehicle’s high speed performance remotely, for a fee.
Really, Charging for getting your seats working when yiu e already spent at least $40,000 on the vehicle (or more now!). I have a Honda CR-V with heated seats at it didn’t cost me a penny when I bought it! I definitely wouldn’t buy any car if I was charged a fee for having my heated seats working!
Here we go again if your car requires premium fuel, put premium fuel in your car because you put the cheaper gas in there and you step on the gas pedal you’ll hear valve shatter that’s because they’re low octane gasoline. The manufacture knows what grade of gasoline they designed the car for not Scotty.
Just found the channel and these myths are good to know. With the hand/arms gestures, the manner of speaking, and the screaming at the camera, Scotty can be the next Senator from Vermont.
Haha the remote extension trick is an old mechanics trick, learned that one when I was a 1st year apprentice out of laziness when U wanted to open a car for someone from a distance 🤣 I was just telling a work mate about that trick yesterday 👌
I've got a 2000 Audi A4 1.8T, engine code ANB, and it definitely runs better on high-octane fuel, although it says 91 will be fine on the inside of the fuel lid. Maybe in those days, engines weren't as finely tuned as today.
For the record I held off on my spark plugs until 100K miles, even though the manual called for them at 75K. (Modern Mazda engine, iridium plugs) I arguably wasted money. The old plugs I pulled out barely showed any age and the gap was still spot on at 0.044”. I still did the job but I’m definitely getting up into the 200s before I even glance at the things again
My Fiat 500 states it needs an octane level that’s between mid-grade and premium. If I put anything less than premium in, it runs noticeably worse, including losing a little power on hills. My tank is small and I don’t drive everyday, so it’s not a big deal to get the premium.
I learned the remote to the head thing from Mythbusters and I use it all the time, people think i'm stupid until I show them the mythbuster's video. Used to use it when I worked as a lot attendant and a car salesman because it made finding certain cars on the lot a lot easier.
The other side on the A/C issue is that cars are much more aerodynamic than they used to be. Back when cars had all kinds of weird styling that caught the wind like crazy, then opening the window probably didn't make that much of a difference on the drag. But nowadays, every crossover looks like an identical blob because that's basically the optimal shape for a vehicle of that size, and anything you do to change that shape (like opening the windows) will noticeably hurt the gas mileage much more than running any electrical component inside the car.
That's true and also the old AC units sucked up lots of power. The new ones are more efficient but on small engines might only drop the temp 20 degrees. The old ones, working properly could freeze you out in the Sahara. With modern cars the break point is about where you don't want wind blowing in.
A 3,000 mile oil change was unheard of until Jiffylube came on the scene. Back in the day it was recommended between 5,000-7,000 miles and it still is for most manufacturers now. Car engines are supposedly better as is the oil especially the synthetics.
Many Toyota Camry Hybrids and Prius Hybrids run 10,000 miles between oil changes in TAXI, UBER and LYFT service. They last 300,000+ miles and keep going. Most is city driving and short trips too with alot of idling. Full synthetic 0W20 Oil used.

I looked up mitsubishi today and it says #6 in reliability brands. So can we get a new honest opinion because Im curious if this myth is true. Because mitsubishi was bad but they're beautiful japanese cars
Scotty, that's RIDICULOUS!!! Everyone knows the key fob thing won't work if you've got too much air in your head!
Scotty your talking with your hands again
What’s your take on the new Tacoma with a turbo 4 banger vs. the now 3 year old 3.8 frontier powertrain?
There's a myth that says if someone is out in their driveway yelling and waving their hands around and no one is around, they are probably crazy.
Either that or they own a GMC.😂
Stick a camera in front of them and they're all right!
Does seem kinda sketchy.

It looks like he's had enough beers already.
He's spot on about super unleaded gas. I have a 2014 Honda Accord 2.4L my kids have named "Dad's Taxi." I switched to regular unleaded from super because of the rising gas prices. I was averaging around 26 mpg (suburban driving) on super and now I'm averaging about 28 mpg on regular and it actually seems to have more pep. 2 mpg may not seem like much, but that's 20 more miles on 10 gallons of gas. That's an extra day of school runs for me.
I never would've thought that would make a difference like that. Figured it would make no difference at all for an engine tuned for 87 like that.
Great car too, the final Accord model I liked.
Also there's the huge savings. Depending on your locale
you know in the owners manual it actually tells you what level of octane gas you should be using as thats the gas that was meant for your build of engine
Same for the reverse. I’m supposed to use the high octane gas in mine, but yeah pricey. I’ve lost some horsepower, but my car still has 320 even with that. I’m not driving a bajillion miles an hour. I’m good w the savings.
My car's owners manual recommends premium gasoline.
I remember the Mythbusters testing the air conditioner vs rolled down windows thing. They came to the same conclusion.
Rolled down windows thing?

I once was asked to see if I could figure out why a motorcycle kept having carburetor problems. I ran it until it was out of gas and then the owner told me, "I always put premium in it." I checked what octane it specified and it was low octane. After about a quarter mile of having the correct fuel in it, I had it fixed for her. She was really happy.
Most likely water or somthing else contaminating it or old gas... You can run 100 octane fuel on a motorcycle meant for 92 octane and it will just run like normal. Only the other way around using to low octane causes trouble.
@@a64738 No; it needed the proper octane rated gasoline.
@@a64738 What you just said: "No you're wrong, your experience is invalid because I think I know better than you." He just said he tried to put lower octane in it and it worked better. Not all motorcycles are built equal. :)
In E10 gasoline the ethanol and gasoline can form two different layers therefore cauaing problems in engines with carburetors. The problem is avoided if new gasoline is used or E10 is avoided, also direct injection engines are not affected.
@@Loanshark753 You are quite correct. Ethanol contains Oxygen. As EFI engines have an O2 sensor. The ECU will adjust the mixture automaticity. This is something that an engine with a carb can't do.
I replaced my spark plugs on my Toyota Tacoma recently at 120K miles. They still looked like new!
I remember back in the day when we used to have to replace spark plugs every 10K miles because they were shot.
The thing about car myths is that many of them were true AT ONE TIME, but not true anymore. People just refuse to believe that things have changed when it comes to doing maintenance on your car.
"I replaced my spark plugs on my Toyota Tacoma recently at 120K miles. They still looked like new!" That does it. Finally I'm convinced not to replace (actually, to have a mechanic replace, because on a V6 engine the back bank is a bear to get at) my 2011 Toyota Venza's sparkplugs. It has 95,000 miles but as little as I drive, 3K miles a year at most, the engine will outlast me. Thanks for the input, BD.
My cousin & I switched my used 2005 P74 Ford Crown Vic V8 4.6L spark plugs, 8x. Bosch double platinum. I expect my plugs to run 30000mi or so. 220000mi.
Imagine sitting in stop-and-go traffic on a hot summer day, with hot-running cars all around, and you've got your windows down instead of using the A/C to try to save a little money. In my early driving days, I didn't have A/C and sitting in traffic on a hot summer day was brutal.
The remote key range doesn't depend on its position relative to your body but rather its orientation. Depending on how the antenna is oriented within the key you simply get a better range holding it upright or in a 90° angle towards the car. With most keys I found holding them upright slightly above your head will already give you maximum range. In a parking lot with all the parked cars of course they're gonna absorb the signal if you "shoot from the hip".
I reach in my pocket and press the button and the car unlocks from 30 feet away.
@@CraigGrant-sh3in Of course it also depends on how strong your keys signal is to begin with. Some work across the whole lot, other will require you to have it in sightline.
or you could press it multiple times and it can reach. I do try it and have luck sometimes. maybe the orientation has to be the reason
True. Changing or modifying an antenna cannot give you more power in all directions.
It can give you more power in specific directions, but only by causing less power to go in other directions.
As always, Scotty is right on in this video ! But just one thing to remember if you change your oil every 10,000 miles make sure you put a high mileage filter on . If you use a regular filter and you go 10,000 miles the paper starts to break down so make sure you use the correct filter for the higher mileage.
My oil would be sludge by 10000 miles unless my life was solely on the interstate. In fact I have bad luck with 5000 intervals. Like everything else, there's some bad parts floating around and you really gotta be observant. $15 oil filter is not something I'd buy when a $1-3 one lasts a year and 2000 miles.
I agre
It’s good to see Scotty and The Car Care Nut agreeing on stuff. Don’t overfill your gas once it stops.
I've been doing that for the last 4 years. Now I'm worry.

I didn't know about the key fob trick After doing some quick research, it looks like the water is acting as a reflecting surface.
In this case, I maybe a paraboloid reflector could be used to really concentrate the key fob's signal in a particular direction.
It works but I get better range if I touch it to the bottom of my jaw bone instead of the throat. It's the curse of owning one of the smallest cars in the parking lot.
Paraboloid? Nice, had to look up that word.
Some say use an open mouth instead as a reflector of sorts.....seems to also work.
As the rays go thru your head and give you cancer, the range is extended twice as far! Yipee! (Hehe, just kidding)

Thank for the video 2020 F-150 2.7 liter, I seen on the forums people saying higher octane gas give you better gas mileage so I tried mid grade and found that to be false, I got better mileage with 87 octane, 89 was 60+ cents more per gallon.
Totally agree Scottie - as a retired Shell fuels engineer, all you need to worry about is only buying Tier One fuel and your car will run perfectly.

Important tip: Just because your spark plugs "still look new" that does not mean they are not worn.
They can "look new" AKA "Clean" but still have a worn down electrode.
Meaning the Gap between it and the contact is wider then it should be.
Change spark plugs according their specs (time, milage, ect) and not so much the car's manufacturer's specs.
I've seen plugs crack the porcelain and arc at times causing a misfire. It's why if it misfires intermittent it's probably plugs or wires.
Myth Busters also did the same experiment. They tested a modern car with AC & drove it with the AC on, then repeated the test with AC off, & windows down. Driving with windows down increased fuel consumption compared to windows up & AC on.
And there are still some specialist that say "windows open is better".
I get it for low city speeds.
For me was the best having a roof window tilted, rarely needed the ac, but in combo with ac that was great...warm air under the roof just was pulled out while pushing in cold air in the bottom, and it got cooler.
@@mammutMK2 I don't listen to the so called specialists. They tell you windows open is better, yet actual tests prove otherwise. A properly working a/c system in a car draws bugger all power, especially the rotary compressor types built in the last 30 years. Even my 1976 Mercedes has a rotary a/c compressor from factory, not only this, I'm a retired auto engineer, so I do know what I'm talking about, unlike these "specialists" who just want your extra money for fuel.
I prefer window open to AC. Especially in Tuscan AZ during the day. Had the window open & the AC on. Was burning my left arm & face with the window up.
@@Elizabeth-rq1viwindow open and AC on??? it's one or the other. you leave the AC running while window is open, you are only overloading the AC system.
@@marrionberry8848 with the window up my left arm was getting burned! I don’t live in Tuscan so that was quite the experience!

After buying cheap tires for 10 years I bought a good pair and I had no idea how important it was.

HAHA, are you serious? the hangook tires and the like only last half the time and are garbage quality for performance, they are cheaper for a reason.
Scotty you educated us on this topic a few years ago. I immediately showed this to my young son then and now shot a video of this on my phone as a helpful reminder and sent it to him. He has learned lots from you (at only 18 yrs old) because I have learned a lot from you. Love your channel and a happy subscriber.
However, never trust a mechanic who lives in his trunk......🤣😂
Back in the day all we basically had to do was keep the carburetor clean, occasionally flush out the cooling system, and change the engine oil and transmission fluid. Those old push rod engines were pretty easy to take care of.
So you had a pushrod engine with no air filter, fuel filter, distributor cap, distributor rotor, wires, spark plugs, water pump, or belts?
@@luisdetomaso867 He never had to worry about that. He only put 300 miles on his car annually.
And they didn't last for very long, it sounds like in your case they probably lasted you like 3 years?
@@scarfacefan1100 Over 30.
Totally disagree, cars in the '50's, 60's and '70's rarely lasted more than 100,000 miles. Also, carburators sucked.
My golden rule is to follow what the manual says and disregard everything else. The people who designed the car know exactly what it needs.
Except when it comes to oil change frequency. Just do it every 5k and disregard the computer oil change interval. By the time the damage is done, it's out of warranty and NOT their problem!
Wrong.
Accountants rule the bottom line for companies not engineers.
They talk about lifetime diff, trans and transaxle fluid (BMW etc) this is false. Their definition of lifetime is different from yours. Oil, I would say do every 5k miles using synthetic, if you do city and highway driving. It's such cheap insurance, you'd be insane not to. My car has 275,000 on it, oil changes every 5k miles with a filter change (Napa/Wix/Fram TG or Ultra)
totally wrong
You honestly believe transmission fluid never needs to be changed?
Wrong most are oil conditions are severe, therefore intervals are half...
I used to listen to Car Talk on NPR - Scotty might be my replacement car info show.
“Arm
Leg
Firstborn” on the gas pump! That was hilarious! 😂😂😂
I find that since I do a lot of highway miles at 70 mph and I use full synthetic, my 150,000 mile 2010 Toyota Yaris runs great! I can take a (supposedly) 10,000 mile filter and change it out around 4 to 5 K, which gets new oil introduced into the filter to replace what was taken out, and run another 3-4k before changing it out completely. Having the filter changed often is cheaper than changing the oil outright since much of the work of the filter is to keep the engine clean and oil free to do it's job. On occasion, I will run some MMO in the engine just before a full oil change. We are about to take a trip to Chattanooga from St. Louis in June, as we have made several trips to Atlanta in the past three years with the car.
It's not for sale is it?
Oil interval is right on the money. I use Mobil 1 on my daily and change it every 5k miles.
I used to get oil changes: 4000 5000mi with my used 2002 Jeep Liberty 4x4: 2013 to 2018. Towards the end, now(used Ford P74 Crown Victoria V8, 2005) I get synthetic oil changes. Every 6000mi or so.
Scotty you make amazing videos for people like me who didnt have a parental figure who was any good with cars, or at the very least willing to teach what they know.
Scotty is so right about the EVAP system getting raw gas in it if you overfill your fuel tank. I use to have a habit of doing that years ago when I owned a Chevy Venture van. The last time I filled it up I went home and a few hours later went outside to leave and smelled a very strong odor of gas coming from underneath. Upon inspection I could tell it was in the EVAP system so I took it in and they replaced it and they told me not to overfill the tank but to stop when the automatic shut-off stops pumping gas into the automobile. I've never had any trouble with any other vehicle again by taking that advice.
I bought a used 2014 Navigator and found that when the gas tank is full and the pump shuts off, my gas gauge reads just 3/4 full. The computer shows the full range to be O.K. When the gauge reaches 1/2 full, it then becomes accurate to the computer and it reads fine all the way down to empty. A mechanic told me that the gauge accuracy was probably affected by the previous owner topping off the tank after the pump shuts off. There's no other issues, so I'm not planning to replace the EVAP system to fix it.
Not to mention that just about every gas pump in America says on it "DO NOT TOP OFF". There's a good reason for that, folks! Thanks, Scotty, for putting out there what that reason is!

@@rhiannablumberg4803 Hello Rhianna. Welcome to TA. (Top-Off's Annonymous).
I just ran a fuel injector cleaner and replaced the coils and spark plugs in my wife’s 2008 matrix. The parts were all original, and you could feel a little rough idle when the car was cold. It couldn’t of been any easier. The car runs as smooth as silk now.
I was worried back when I was about to buy my next car and it would be our first fuel injected one, because what would I do if it needed a tune up? No carburetor. I should not have been concerned. Today’s cars are so much better without carbs!
I have never had to replace a coil. Fuel injector gas additive every 4-6 months and spark plugs per the maintenance schedule keeps my three cars running fine.
RedLine additive is by far the best!
I had my Ford P74 2005 V8 Crown Victoria LX spark plugs swap out. I'd agree, replace the ignition coils too. I later had 2 coils replaced: $$$ 😌. Engine parts-components function smoother, better when new. Better MPG ⛽️ too.

About oil change interval. in 2008, I bought a 2004 Ford Focus in California with 58,000 miles on it. With the 2.3L DOHC engine. I changed the oil and filter every 5000 miles, with full synthetic of the recommended viscosity. In 2021 I gave the car away to a friend, with 149,000 miles on it and it still uses no oil between changes. The only engine work, besides the 100,000 mile maintenance was it needed the intake manifold replaced as it had cracked. I got one from a car recycling yard. In 2023 my friend is still driving it.
My point is that I concur with your oil change recommendation.
I had an older Dodge Dakota that would not run on 87 octane fuel. It would lose power and knock and ping. I had to use the, at the time, 89 octane fuel and it ran great.
yes, older cars REQUIRED higher octane gas. Otherwise, they would "knock" on low ocatane, damaging the piston chambers.
Thanks for the video!
3:22 - hey I have an 2004 Porsche Cayenne v8, it says it needs the high 93 in it. So are you saying it would be find with the regular 87, just that the HP will be lower?
3:34 - what is considered a modern vehicle? 2000 model year+?
I’ve been in the car service business for 30 years and our fuel additive folks took premium, mid grade, and regular fuel and poured 1 tbsp each in a white saucer and lit them. When they burned off, the premium had the most black soot. It burnt dirtier
my 19 F150 with 5.0 would knock and ping like mad if I didn't run 91 octane. It was like getting a raise when I got rid of the POS at 46K miles due to transmission issues. My new truck runs 87 without issue saving about $35 a fill up.
8:36 You forgot to mention summer air vs. winter air. Very important.
Virtually every used car I’ve ever bought I’ve improved the fuel consumption, acceleration and top speed by just giving it a good old Italian tune up. Most people drive too slow and the engine gets clogged up with carbon etc - use the performance of the car and you will clear all that crap out and the car will run better. Plus check tyre pressures regularly when cold and use top quality oil and filters.
Scotty 2006 Cadillac can I stop using premium gas? I and many people love your site. Thanks Walt
Scotty, average mileage per year here in the UK is 10-12000 miles. I always get my car serviced according to manufacturers instructions... which always includes an oil and filter change every 10-12000 miles.....so what do you think of that? It's a Maza CX-5 2.2 litre diesel, by the way.
Regular gas in UK has 10% ethanol.
Super gas from Esso in the UK is ZERO ethanol.
The extra cost of super is offset by the extra mpg I get.
Listening to this Scotty. brings back all the memories of my time being a Spanner Man. in the 60s 70s always adjusting something to keep them running
Back in 1986 I bought a new Chevy sprint. It has a 1 liter 3 cylinder Suzuki motor. Some people had complained that the motor would shake. Come to find out they had put in premium gas. Chevy put out a bulletin to not use premium gas.

When I first bought my 2015 Silverado 5.3l I tested the different octane to see which one I get better mileage. Each octane test was 300 miles with the AC on. 89 octane got 1 more mile per gallon than 87, and 91.
You know Scotty is old school when he talks about gasoline and calls 93 “high test” I’m 53 and remember when they called it that.

I did a study on my car to test different grades and gas stations for fuel mileage.
Premium didn't make a difference, but brand did. Chevron gave me the best mileage, Arco gave me the worst (i didn't test any brands that weren't on the official top tier list)
Christ, if I was changing my oil every 3000 miles I'd have to change it every month 🤣
my 87 VW vanagon uses premium. I still have it. Still runs great. read your owners manual to see what it recommends, and follow it.
Regarding fuel, any thoughts on the running your tank dry vs keeping at least a quarter full. I was always told, and read in the manuals, that you should aim to nit let your tank drop below about a quarter full else all the waxes and impurities in the fuel that normally float near the top of the tank will get sucked through and mess up your engine. My sister refuses to fill her tank more than a quarter full because she says she can’t afford to spend that much on fuel (ignoring that this means she has to get fuel about every 3-4 days, and often has to go to more expensive garages because she doesn’t have enough fuel to get her to a cheaper one, plus in the past when I’ve filled her tank she’s just run it down to below quarter full and will not fill it over about quarter full). And she wonders why she’s getting through a fuel filter every year, has to clean her plugs twice a year and has to replace various sensors every year or two.
Every mechanic I've talked to has said to never let your fuel get below a 1/4 of a tank if you can avoid it. She should instead fill it to half a tank and then refill to only a half tank(once she gets to 1/4) and she would be paying the exact same amount.
The fuel cools your fuel pump. Running it too low significantly decreases the life of your fuel pump
In my 2017 Hyundai Elantra, I get about 3 MPG more with the windows down than I do with the A/C on (not even blasting at full power). It has been consistent over 6+ years, all working at the same location and living in the same house (so no adjustments for different driving conditions). My commute is half freeway and half surface streets, a total of 13 miles each way.

I've gone to stations and they were out of regular grade gas, and we're offering high grade for the same price, so I filled up. On both my 2000 and 2014 Civic it actually tripped my Check Engine light. It didnt affect the way it ran, but did turn the light on. On the next fill up of regular, iit went away both times.

The one thing you can do to get the maximum mileage over the lifetime is change your oil and filter every 3000 miles with no exceptions. I don't care what your manual says when they tell you every three months either mileage not months. Yes I was a professional mechanic and I drove a 1987 GMC Full Sized Jimmy 315,000 miles until it was wrecked by doing just that with Mobile One synthetic. I pulled the engine and disassembled it to find no appreciable wear anywhere.
To be quite honest we change oil at the prescribed intervals, which are 15 000 kilometers (about 9300 miles) for many Toyota models. For some Skoda models the interval at least used to be 30 000 kilometers (about 19 000 miles). We have never had any problems because of this. Some people actually say that it is even safe to only refill oil, and just change the oil filter about every second year.
Some people would be wrong.
Modern engine oils are incredible for long life. 10,000 miles minimum, 16,000 miles comfortably.

I drive a Honda CR-V and it tells me when to change my oil! It’s usually around 6 months and around 15,000 miles!!!In years passed we always changed at 3,000 miles! My csr runs perfectly and have never had a single problem. Oh, and my fob needs to be pretty close to my car to work which is fine with me as I really don’t want to unlock it when I’m not even close walking from a store!
@@sandybruce9092 Good for you. Nonetheless, we actually change oil at the recommended intervals, which is about every 9300 miles for a Toyota Yaris. Thus, the question is not if the car runs well, if one changes the oil every 3000 miles. The question is whether it runs just as well when one triples the change interval to about 9000 miles.
@@jonebjrheim3148 Yes, my car runs perfectly - my husband knows cars and he wouldn’t “allow” (I’m using that word euphemistically) me to do this if I was going to make a mess of the engine! At about $100 a pop for an oil change it just isn’t viable for us! And I NEVER go to a dealer! I can work with the salespeople when purchasing - and I’ve been purchasing our cars for over 30 years - but I won’t deal with service people who always want to sell me something just because they think I’m just a stupid female!
One car myth was about pickup trucks with the tailgate up or down. You still see some tailgates with openings in them for air flow. I remember reading about it and with the gate up it actually made the truck more aerodynamic because it created a rolling cell of air in the bed area. Don't know about modern trucks, maybe the difference between 16.5 mpg and 16.8 mpg is not enough to notice.
Many years back, a show called Mythbusters tested that and found the myth was wrong, and figured the same thing you are saying that.
“Usually your head is attached to your body” 🤣🤣🤣
Correct pressure for the TIRE. For instance, a dura-trac E range tire takes 80 psi.
Been using the under the chin thing for years.... And yes, people think I am nuts. But, it works.
My 2015 Prius really never required a tune up at all. The manual said to change the spark plugs after 100,000 mi. I didn't because the dealership wanted almost $300 to do it (lots of plastic covers and windshield wiper junk and metal bits to remove just to get to them). I didn't want to take the time to do it myself, because I figured I would take four or five hours to figure out how to do it, even with TH-cam videos. I let the spark plugs go and finally decided to have them replaced by the dealer at 240,000 mi. The dealer price had dropped to about $220 by that time, so I told the dealer to go ahead and do it.
The original spark plugs were a nice very light tan color and the gap did not look horrendously wide although I didn't measure it. The car got about 2 MPG better gas mileage after the spark plug change.
I noticed in my 06 camry the fuel vent where you fill up the car is located at the top of the fuel tube, so gas can't get into the vent.
Tires are important... wonder why mechanics and body shops never have the same tire to match the others. And end up going back for balance reasons and tire wear down. I always make sure I have the exact same tires.
Thanks Scotty for sharing the knowledge with us.

Good myth busters . Can you also bust the myth of using a better synthetic oil to improve nvh level or whether it makes the car run more smoother ?
0:46 for the remote under the chin trick to work, it's not enough to put it under your chin. It's placed there so that you could make a buzzing sound with your mouth and help amplify the remote's signal(s). Supposedly, anyway.
A local station charges 45 cents more per gallon for 91 octane non-ethanol versus regular 87 with 10%. I get enough better mileage on a full tank of 91 to come out slightly ahead versus using 87, but only at the current price point.
I actually do the same and I can notice a difference in power with the extra chemical energy too. I get weird looks filling up with rec gas though.
Non ethanol is definitely the way to go however where I am at the only non ethanol is 91 octane with a significant increase in price. I only get about 2 extra mpg which isn't worth the difference. If I had more money to blow then yeah, 91 ethanol free > 87 10% ethanol.
Well basically, if your car loses (horse) power because of no premium fuel, what it essentially needs, it's NOT good and running perfectly fine tho. It runs perfectly fine when it doesn't lose power because of other fuel then recommended. It's not recommended by the manufacturer for fun, they don't get a cent from BP or Shell.
8:13 I saw a guy with truck tires on his crownvic, I asked him why. He stated that truck tires last longer than regular car tires.......🙃✌️

We had a Nissan rouge in the shop with bfg k02’s…… cause they kept killing tires on potholes 🤣🤣🤣🤣
Amazing about the key under the chin. Never heard of this!
This is why I'm so glad I still ride a horse to work.
If you place your key remote against your temple, it does the same thing.
I’ve been doing the remote to the head trick for years 😆🤣🤣🤣🤣
there’s a few in government peeps that could use the battery to the head
@@HotRod-wv4vm no few but all
With my newer car, I only "overfill" to the next 25 cents. With my older car, I could easily fill up another dollar in there. It does seem that the modern cars are more "full" when they shut off.
I really mistreated my 2015 Prius that I used almost exclusively for Lyft driving. My oil changes sometimes were 20,000 or 25,000 miles apart. The car has 310,000 miles on it and is still working fine, although my fuel economy has dropped from about 53 MPG when it was new to about 46 MPG. Imagine how long this car would go if I changed the oil every 5 or 10,000 mi.
thats crazy and hilarious
@@SmokeDogNY420 Yeah, pretty nonsensical. Those Prii do soldier on, though. And all that time, I never had to top up the oil. Every time I checked it was at least half way between FILL and FULL.
Have you replaced the battery?
@@ichbindarren No. There appears to be no need to do that. That car has nickel metal hydride battery cells in its pack (it's not the plug-in hybrid model, which in later model years are lithium ion). I think the degradation of the NiMH cell is more related to age and temperature cycles than it is to miles driven. In my car, the time it takes to charge the battery enough so that the gas engine turns off is still not much more than when I got the car new.
@@bobbabai change the car battery after the warranty is done. I changed to an AFM in my Toyota Camry Hybrid. The large hybrid battery is for life of the car.
DAMM Scott I never get tired of listening to you talk about cars I know a lot about old cars but not the new stuff I’m learning stiff from you thanks.
Can you talk about car companies charging to turn On heated seats, which are installed, for a fee? Or they charge for increasing the vehicle’s high speed performance remotely, for a fee.
Really, Charging for getting your seats working when yiu e already spent at least $40,000 on the vehicle (or more now!). I have a Honda CR-V with heated seats at it didn’t cost me a penny when I bought it! I definitely wouldn’t buy any car if I was charged a fee for having my heated seats working!
When I was in Houston, I was in the left lane going 100mph and would still have people pass me 💀💀💀💀.
The 11 myth is saying "I do." Happily ever after? Yeah right.
100% correct
Lol
I remember the video you did about the guy driving with the air conditioning off and then the windows down on the way back lol
Here we go again if your car requires premium fuel, put premium fuel in your car because you put the cheaper gas in there and you step on the gas pedal you’ll hear valve shatter that’s because they’re low octane gasoline. The manufacture knows what grade of gasoline they designed the car for not Scotty.
Just found the channel and these myths are good to know. With the hand/arms gestures, the manner of speaking, and the screaming at the camera, Scotty can be the next Senator from Vermont.
Haha the remote extension trick is an old mechanics trick, learned that one when I was a 1st year apprentice out of laziness when U wanted to open a car for someone from a distance 🤣
I was just telling a work mate about that trick yesterday 👌
I've got a 2000 Audi A4 1.8T, engine code ANB, and it definitely runs better on high-octane fuel, although it says 91 will be fine on the inside of the fuel lid. Maybe in those days, engines weren't as finely tuned as today.
It took me way longer than it should have to realize he wasn't swatting flies away from his face
The manual that came with my 2019Ram Rebel with the 5.7l Hemi says ONLY use mid-grade gasoline and by God, that’s what I use. No deviation.
For the record I held off on my spark plugs until 100K miles, even though the manual called for them at 75K. (Modern Mazda engine, iridium plugs)
I arguably wasted money. The old plugs I pulled out barely showed any age and the gap was still spot on at 0.044”. I still did the job but I’m definitely getting up into the 200s before I even glance at the things again
My Fiat 500 states it needs an octane level that’s between mid-grade and premium. If I put anything less than premium in, it runs noticeably worse, including losing a little power on hills. My tank is small and I don’t drive everyday, so it’s not a big deal to get the premium.
I LOVE this guy!
Scotty, when I fill up my EV, should I use regular electricity or premium?
Regular, of course. Dealership should of briefed that.

I learned the remote to the head thing from Mythbusters and I use it all the time, people think i'm stupid until I show them the mythbuster's video. Used to use it when I worked as a lot attendant and a car salesman because it made finding certain cars on the lot a lot easier.
The other side on the A/C issue is that cars are much more aerodynamic than they used to be. Back when cars had all kinds of weird styling that caught the wind like crazy, then opening the window probably didn't make that much of a difference on the drag. But nowadays, every crossover looks like an identical blob because that's basically the optimal shape for a vehicle of that size, and anything you do to change that shape (like opening the windows) will noticeably hurt the gas mileage much more than running any electrical component inside the car.
That's true and also the old AC units sucked up lots of power. The new ones are more efficient but on small engines might only drop the temp 20 degrees. The old ones, working properly could freeze you out in the Sahara. With modern cars the break point is about where you don't want wind blowing in.
Old and boxy equals comfortable and easy to see out of. Also cheaper to insure. Also slow as a turtle. 😂
A 3,000 mile oil change was unheard of until Jiffylube came on the scene. Back in the day it was recommended between 5,000-7,000 miles and it still is for most manufacturers now. Car engines are supposedly better as is the oil especially the synthetics.
Many Toyota Camry Hybrids and Prius Hybrids run 10,000 miles between oil changes in TAXI, UBER and LYFT service. They last 300,000+ miles and keep going. Most is city driving and short trips too with alot of idling. Full synthetic 0W20 Oil used.
Back when I started working on cars in the 70s people used to change oil about every 3000 miles gotta remember oil wasn’t as good as it is today
