Hey scotty, great video, I sit in my car at lunchtime in work and listen to the radio, about two months ago the battery died and the car wouldn't start (without a push). I've been running the car ever since while I've been sitting in it and haven't had a problem. How should I test the battery to see if it needs changing? I have a multimeter if that's any good. Car is a euro 1.8 valvematic gasoline Toyota avensis.
Scotty Kilmer pls compare headlamps halogen vs led vs hid
Do a video of What happens when you Putting Gasoline In A Diesel Car or vice versa
Brian Galvin Hay Mr. Brian I'm not a car expert but i always hear Scotty and all people like him advice others to go to batteries shops and there they will check it for you for free .
Scotty Kilmer what if it's cold? Could u start it and let it idle for eh 20 or 30 minutes then shut it off?
i love how Scotty dances with his arms as he talks... he actually looks like he's conducting an invisible orchestra -
Trev yep
Frank. T he is Germanic.
Watch at double speed.
Ha ha 😂🤣🤣 good one!!👍
hes like one of those dramatic cartoon characters that i used to like
How many people came here on a hot day.
May 25th 2024 palm bay Florida, its 90° and sunny as hell.
113° here in Lucknow, India.😂
🙋🏾♂️😂

113 degrees f northern California
Last night I had a nightmare my engine blew up just sitting in the driveway idling... then this was in recommended videos. TH-cam algorithm is creepy accurate sometimes.
No way.
A horrific nightmare.
May the engine with oil be with you
That celica went from 240,000 miles to 250,000 in less than two videos
Juan Moreno so 1 videos then
Does it really matter? Its thereabouts
Juan Moreno went from being illegal alien to an asylum refugee y lest than two videos?
@@Tahara-Aichi "lest" 👌
I know right. I don't think he drives that car anymore.
Scotty taking 1M people to school again today
I hadn't noticed he gained that many subs until seeing your comment
Right. It's like a free education.
How original.
Looks like 900,800 people didnt show up to school today.

Thanks for your advice especially about the catalytic converter. As a retired fire fighter went to many car fires because the red hot converter was parked over dry leaves, you know from trees well many a car was burned beyond recognition because of the driver leaving the car run while they ran into a store or whatever. Live and learn Scotty, thanks.
Agreed. I put an OBD gague on my dash that shows various things including cat temp.
I've seen it go between 900 and 1500⁰F.
That is _serious_ heat.
Far and above the ~200° your car engine is kept at.
@@davecrupel2817. That’s how catalytic converters work, they need to be far hotter.
@@robertt9342 yeah I never knew that until I installed that gauge and saw it for myself.
When I've had a stressful day I watch Scotty for an hour and I feel better.
Don't lift your hood as my buddy Scotty said to do. You will forget at some point then "WHAM," your hood flies open before you get to 50 MPH.
Actually your hood won't fly open. I sometimes pop my hood to check the oil on my 98 ram for the next morning. One day I forgot it was slightly open and I was going down the highway and I noticed it was kinda shaking and I remembered I didn't shut it all the way so I pulled over and closed it. No big deal. I noticed it at first because I have a grill guard on my truck and I noticed I couldn't see it so that was a suspicion. Another thing your hood won't fly up because its still latched and you have to pull the handle under the hood before it will go up.
@Fox-E Exactly. Every car or truck I've ever owned has a hood latch that you have to depress, slide or lift in order to open the hood. I've never heard of any person's hood flying off if it is engaged in the safety catch but isn't closed completely.
Fox-E (Bonzai) well it kind of is, I was with a friend in his 67 Mustang and the hood wasn’t closed all the way, the safety release eventually gave up and it shattered the entire windshield and bent the hood in half
open it all the way so you wont forget to close it
@@ffhjvbuydb78eb Oh it will though. Maybe not on newer cars but happened to my Mom in her '93 Plymouth Acclaim. Thankfully she was taking back road home and not the interstate like she usually would. A very scary day. It just isn't a good idea. It was the first thing I thought of when he said that. Otherwise, long live Scotty and thanks for all of the tips and entertainment, don't really watch much on TH-cam anymore except for Scotty and old Dead shows lol.
Scotty is going down as a legend.
Scotty is a Legend
He has legended
I wish i could meet a mechanic like Scotty. Scotty is like a second father for us that we have cars and we want to keep our cars for decades .
I revved up my 94 Celica engine and wrote a clean, non-offensive comment.
This is a hanging question in my mind. I idled for 2 hours waiting for a barge. You gave me a sigh of relief knowing that putting an AT in neutral is ok. Thanks scotty.
yeah neutral or park both are good for it drive for long periods is bad for it if you do it a lot scotty is saving people tyranny's by telling them to put it in neutral or park for sitting while the engines running for long periods of time
easily one of the best car channels on TH-cam.
thank you for the quality content!
You have some great videos! I was wondering this myself because when I go to pick my daughter up from school, I let my car idle but it idles in park. Thanks for another great video! I've learned a lot from you and because of that, I'm able to fix certain things on my car now without having to take it to a mechanic for every little thing. Keep up the great work!
Scotty I have several friends that are Master mechanics they are completely sick and tired of me asking them questions I love cars and pickup trucks I like cars from the 1990s up until about 2002 you are the best every time I open a video of yours I get an answer thanks and keep making them
Scotty is the bigest teacher with 1 million students
Some people never look at their car's instrument panel. The only gauge they seem to be familiar with is the fuel gauge.
I know people not even the fuel Gage..lol
CastleBravo That’s not true. I look at the Tachometer occasionally
Because it takes along time for new cars gauges to start actually telling them things though most old cars gauges are very accurate because it’s been literally used lol
I wish my car had oil pressure and temperature gauges. My previous vehicle did and I tried to keep an eye on both.
Lol
Scotty owns the best voice of reason I have ever seen on a TH-cam channel . Bro you rock
Thank you for posting this video Scotty! I have been trying to figure out why it is that I was having soo much trouble out of my truck due to my cats being bright pink/ red , and my thermostat housing compartment decomposing, and my exaugst smelling of antfreeze. I 've also had to change out my radiator and my thermostat as well. It's been a big drag knowing that there's soo many things wrong; that I really didn't know where to start.
lol i love how as soon as something goes wrong in a car Scotty suggests buying a Toyota i think Toyota should sponsor all of your vids
Toyota, Mazda, Ford.. Lots of the spare parts are interchangeable, so getting a part for the right price is easier too. If you find the model independent SKU number for your spare part, you'll notice 20-50 different cars using that part. Then suddendly, finding something at 1/5 the price for a 10 year old VW to put in your BMW makes you feel very smug.
Of all the cars Scotty could own, he chooses an old reliable, durable, inexpensive fuss free machine. He really does know his cars.
Tore Lund I’m not talking how reliable or finding parts is I’m saying that I love how Scotty gives up on any car and says Toyota Toyota thousands time yeah it’s reliable but what is the fun of driving a Toyota except supra ofc and also note finding parts in Europe for Toyota is a bitch like VW is more reliable then Toyota in some countries
Toyota makes sense to me. I have 6 cars in my household between my wife and I and the kids. They include newer models of Infiniti, BMW, Mitsubishi, Acura, and Volvo. However, my daily driver is a 98 Corolla I bought for my daughter to learn to drive on. I bought it used. It was cheap, great on gas, dependable, retains its value, and needs very little maintenance. When I need parts, I can find aftermarket parts on Ebay very cheaply. My next car will be a Lexus.
Sorry this was just a stray thought on my part too, but this is the internet and varying opinions are always promoted to life and death arguments ;).
A friend of mine idled her car 8+ hours a day! In a few months the electric fan cycling burned out a fuse. Which cycled the AC compressor a huge amount due to heat and AC pressure switches. Which burned out the compressor clutch, which seized. The belt went bad, ruined the tensioner, over-headed the Head. Half hour idled ok, 10 hours a day, better be a police car!
Your are the most informative and valuable producer here, thank you
Sounds like your friend had more issues before hand. Any modern vehicle can idle in definitely so long as the cooling system etc as explained in the video is in good condition. As long as you have enough gas you can idle forever. Take care of your vehicle and you won't have to worry about it blowing up because you let it idle lmao.
Went throughout the entire tank of gas in 1 day?
you rock sir. the only mild disappointment is about when you recommended the computer update, based on $1500+ interface hardware (and, yes, software engineer here). keep up the great work! thanks
Thanks for the tip about idling in "drive"! I've had so-called "mechanics" tell me it makes no difference, but anyone with good common sense knows better.
Currently watching this while sitting in my car with the engine on
Same! Lol
Same.
I’m sitting in the car but the car is off lol
@@erinfink6056 hahahahaha
This is why I looked the video up while eating my sandwich lmao
Speaking of rising temperatures, I had that happen in my 1994 Camry for a few weeks. Going even a mile to home, I would see the temp gauge start rising upward. I had never seen that gauge move past the middle for the first five years I'd owned the car. I never did figure out what was causing it, but it eventually stopped tending to overheat as suddenly as it began. It hasn't done that again in the ten years since. Love that car.
I really like your new graphics, Scotty! Don't start changing too much on us now! We like you just the way you are.
Scotty, love the information as always! Cars with automated manual transmissions (or Dual Clutch transmissions) such as the VW DSG or Audi S-Tronic tend to disengage their first gear when you come to a standstill and you see the RPM needle drop very steadily. You'll feel the vehicle sitting as if in Neutral.
My 2016 VW GLI will keep the gear engaged, however, if you light-foot the pedal even on a stop. If you don't push your foot on the brake about 60% in at least, it will keep the gear engaged and add wear to that clutch (you also hear it). Idling with the foot on the brake is about 810RPM with this vehicle and about 900RPM with the AC or heater on.
A dual clutch stationary in drive with your foot on the brake will have first gear selected, but the clutch fully disengaged. In a manual sitting with your foot on the clutch isn't good, because it keeps the throw out bearing loaded. But dual clutch transmissions actually only load the bearing when the clutches engage, which happens when you release the brakes.
So sitting in gear doesn't cause any real wear, but if it's a wet clutch it will use a little extra fuel and shorten the life of the oil slightly as it gets sheared between the clutch plates.
I agree...I always put in neutral and use parking brake instead of holding brakes.
My cousin had a diesel VW Rabbit. He would plug it in at the hospital when he was on ambulance duty. It kept blowing the breaker in the hospital so he was told to stop. SO, in the middle of a good Iowa winter, he would report to work and just leave it running. 12 hours later his coworkers had cold cars (if they could get them started) and he just hopped in the VW and motored home. His record was 8 straight days of never turning it off.
that’s wild, thank you for sharing🙏
Thank you for giving peace of mind for most of us here LOL, I've been doing this once a week just to circulate and charge my battery, because most of Dr. Google's suggestions is "DO NOT" "NOT RECOMMEDED" " IT WILL TEAR WEAR ENGINE" . now I am relief. Thanks Scotty!
I have a 07 police interceptor as a weekend warrior to play around in. It's nice and it has all heavy duty parts including a heavy duty oil cooler.. It runs below the middle between hot and cold.. I love it..
This video value is diamond!
I always wanted to know this. Thanks Mr. Kilmer
I like your channel and thanks for so much info. Idling your engine is hard on the timing belt, your engine most likely won't be at optimum temp so your oil could get contaminated with gas and in diesel's over time your cylinder walls will glaze causing premature blow by so idling long periods over time will shorting any engine life.
I think it is a good idea to rev the engine a little every so often to make sure oil is getting to every corner of the engine.
I gotta do that in a gmc envoy just to keep the air conditioner working effectively
He hit a million!! CONGRATS!! 💓
Thanks for the support 👍
@@scottykilmer lmao almost 2 now!
Carbon build up in Diesel engine?
@@davidgriffiths7696 huh
live and let live combustion temperature lower at idle, cylinders glaze over extended periods and more smoke clogs Egr and exhaust, is a commonly held opinion I have come across. Sitting there idling for long periods in a diesel is said to cause accelerated engine wear.
1 MILLIONS SUBSCRIBERS !!!!! CONGRATS 🎉🎉🎉
thanks for the support!
I just bought a 2001 Celica about a month ago and your consistent references to Celicas makes me feel like I made a pretty good choice.
Now if I can just clear these dang p0171 and p0420 codes to get it smogged.
Very useful i needed heat as im a overnight security guard and it got COLD. All i had was a light jacket. So now im using my modern car as warmth for like 4 hours thanks!
I lived in my 2014 camry for a while. I went from summer to winter so I had to leave it running at night so I didn't die.
Same. My Corolla didn't get hurt by having the engine on idling for hours.
I live out of my 1999 Toyota Avalon, 289,721 miles and counting. I delivered pizzas with it and use it to get me to and from school. I put 100-200 miles on it practically daily. Blessed to be able to have a reliable source of transportation, plus being a Avalon it’s quite roomy sleeping in lol. I have let my car idle for 6+ hours daily. When I use to work security I would let my car sit at idle for 8-14 hours daily. And the car still runs like a champ, paid $2000 for it with 275k miles when I first got it. Original engine and transmission. I have had it for about 9 months now and put about 15k miles on it since I have owned it and countless hours of idling. But I just change the oil religiously and the car just keeps going. After owning this car, it’s definitely Toyota 'til the death of me lol. I wouldn’t consider buying anything else but a Toyota!
@@dannyracker6283 if you ever experience the thrill of a muscle car you’ll forget you even had a Toyota. I used to feel the same way about my Chrysler 200
My old car doesn't reverse anymore, so I use it to just drink or smoke inside of it with the music playing. I don't move the car but only turn it on for the ac/heater and to play music and chill. Its like running a small generator in a small house with ac/heater and a great music system.
@@allisonacton7268 why not just get speakers in your house? 😂
Thanks, great advice. I like to idle with the the A/C on, especially in the summer.
I learned that on a vehicle with a engine driven fan the ac will be slightly inneffective at cooling at idle because the fan isnt yanking enough air through and because of the low rpms on the ac compressor pulley so you gotta rev the engine up a little i say to at least 1,000 rpms
I seem to have picked up the habbit of pushing my shifter into neutral when coasting to a stop in my 2012 Tundra. Any concerns on doing that? I guess it's because I was mainly driving a 5 speed. Great info. I'm glad I found you. Thx.
2:00 in the video. That shifter is for an AU falcon. Nice to see it included In this guys video as they do not have falcons
I like to take my work breaks inside my car, I really need to find a new spot to chill AWAY from my coworkers
Start/Stop systems wear out the engine, transmission, starter etc. Can you make a video on this please.
good idea, thanks
I bet those idiotic Start&Stop systems wear out battery and starter faster as well..!
Just to add to the discussion: I don't own a Stop N' Go car, but I've tested killing the engine every time rolling to a red light in city driving and it saves 10-15% gas compared to idling during the course of a tankful. Typical my trip computer logs 4 hours idling per fill-up so that is around 2.5 liters saved. So the extra wear on the starter and transmission is more than offset by the cost of saved fuel.
Tore Lund it depends on the car too, especially on the fuel it uses,the size of the engine, how long you are at the lights etc. As Scotty said if you own a diesel car then the savings are negligible. If you live in America where the traffic lights are much longer then it would save you more fuel than in a European country.
RestlessJack 00 they do make the car use more electricity as the starter has to work every time it turns on the car but the battery is in use anyway as it is powering the radio, gauge cluster etc.
You are a genius and a good heart 4 sharing!

Honda Odyssey 2019, ac not turning on once the car has not been turned on for hours = cold engine. Just got the car and dealer giving me the run around.
Scotty, love how you provide information in your, sometimes silly, theatrical ways. Truly enjoy your videos even if Im not in need of answers!
Great content. Always learn something from every vid I watch. I admire you for sharing your knowledge and enthusiasm with so many individuals needing helpful tips. Keep up the good work. Also, great editing. I can tell you don't just throw a raw video out. You take the time to keep peoples attention and truly make it understandable to everyone. Keep up the amazing work on cars and in the studio. You deserve every advert dollar you get. As an Uber/Lyft driver this is one questions I always had. you have saved me a lot of headache/ time/ and dough. My hat's off to you sir. Everyone, you need to rev up your engines and listen up to this fine gentleman. You will learn something.
Owner of 07 Toyota prius with 220,000 miles and Scotty's help. Still getting over 50mpg and runs like the day I purchased it. And trust me... Uber takes it's toll on a vehicle. Race to get the passenger, then stop and go in my market. Tons of idle time.
Congrats on the 1mil subscribers
Thank you. This answered a question for me. I have a 2004 Mazda MPV minivan. 65,000 miles and in perfect condition. I baby it. I have in the past slept in it. I have run the engine for AC and heating. I had no problems. Of course it uses fuel but I would sooner pay for gas than a hotel. It was about $20 a night. A hotel $50 at best.
I never thought about popping the hood open to let it vent before, thanks for the tip!
In hot days not bad idea
fully agree with opening the hood slightly to let hot air escapes. in some places, the scorching summer heat is there all year long. even better if you could park under a shade let say a tree.
Thank you, Scotty! I needed this... I have a habit of sitting in my car with it idling for a long time and just wondered yesterday if I was possibly damaging the car. I waste a lot of gas. Lol. I live with a big family and sometimes I will go outside and just sit in my car or drive around for no reason just to be alone.
SPIRITUAL ISRAEL Ay if you have the money for gas go for it 😂 nothing is more relaxing than driving around by yourself
you should worry about the environment not your motor
@@bitcoochie4093 Yeah, while big industrial plants literally pollute the air and water everyday, you want to tell me that an idling car is destroying the environment. 😂
@@bitcoochie4093
La Palma volcano has been erupting for 71 days now and put out billions of tons of carbon emissions, more than a couple years worth of an entire countrys c02. That is just one small volcano, now multiply that by the 31 volcanos currently erupting and you will see how this change in climate is a natural cycle. If humans never polluted it would be the same
@@Michael-ys5cn I've always been confused by the climate change debate I'm getting the impression that some people are arguing that climate change is not occurring at all and then you have people who argue that it's people who are creating the climate change. I think that the argument about climate change has been come really kind of convoluted
You're the funniest "car guy" on youtube Scotty! and I really mean it. ;p Excellent info, delivered in a light-hearted style that no one else can. And of course the trademark sun glasses. Nice touch!!
Scotty you are the best. I don't even have a car and I still watch your channel
Awesome video! Keep them coming!
Question: What cases more wear-and-tear on your transmission: At a red light, keeping your car in "Drive" or shifting to "Neutral" then back to "Drive" when the light is green? Thanks
Shifting it to neutral then to drive of course
Thank you for your wisdom, Scotty.
You’re our HERO!
when I drive for 400 km, I am idling with air conditioner on while having a short nap when feel sleepy at a gas station , and it’s hot weather here in Saudi Arabia. So, I laugh my heart out, when You mention keeping an eye of the engine coolant temperature, because once I walk up from my nap I check two things Time, and The Engine Temperature.
I feel like I just switched to a random channel on the dimensional tv from Rick and morty
I love the short intro
Scotty, great videos. Truly learnt a lot from you. Can you make a video on how often one should change the coolant in a car? Or did you make one vid of this thing that I missed?
Thank you Uncle. All doubts cleared. I drive a diesel sedan. Im happy.
Thanks again Scotty your the Best ...
5.7 l Chrysler/Ram engines have lifter roller failure that destroys the camshaft if the engine is idled extensively such as in Police use.
Great video scotty! just a future idea: you should do in depth installation videos like chrisfix. Thanks!
Good tip on the transmission at idle!
Rev it up Scotty!
If you going to pop the hood, I would recommend just lifting it all the way. That way you avoid forgetting that it is unlatched and driving off. If the safety latch malfunctions you will end up with a really bad day.
hi Scotty good video, I have that '86 Toyota Corolla with 551,000 miles on it and I'm glad I've been doing most of this just out of common sense. I have my idle speed just a bit above normal so it starts fast in the winter but it will also heat up a little faster than normal;even at a long light I'll pop it into neutral and I've never really had to shut it off but that would be my next step, say like a 10 min train or something. By the way the car runs very cool, the temp gauge rarely goes over 1/4, unless I have to idle a lot! Its still running great, its just amazing...original engine and trans still too!
Thanks for the information. I have been wondering about this, now I know. 👍🏼
A Toyota with 250,000 miles, that's not high millage, that's run in 😀
Break in!
Semi new car.
Casey Stoner stop lying to yourself💯
I have a Toyota RAV4 with 275k miles. The engine runs like a top. The only problems are with accessories, and that's normal with any car. The engine is even slightly neglected, but still runs very well. I'd prefer a Honda for ease of repairs. The Toyota is way too overly-complicated and has a compact engine bay.
305K 2011 Tundra and only basic maintenance done to it.
Diesels were built to be started up in the morning and worked all day long, not started and stopped like so many people do...and they weren't built do drive a couple miles and shut off, then repeated several times throughout the day. Gasoline cars aren't so bad, but starting and stopping any engine isn't exactly that good on its longevity as that is where most wear comes from. Course people today don't care about wearing anything out because they don't keep the same car more than a couple years anyhow because heaven forbid they get caught by their friends driving a 3 year old car.
I agree
Thats funny because you get cylinder washing from idling a diesel too long, and it wears the motor out like crazy
@@Taydrum yes ..........you are one of the few people that know this. Also MOST diesels do not get up to full operating temps at idle which is not good. You need to have whats called a idle kick up kit. The big rigs that idle for hours are made a little different that a pickup diesel engine.
@@mlaugh3 It kills me to see people start up their diesels in freezing weather, only to go inside and eat breakfast make coffee etc, all while the engine is idling.... Fast idle or driving (engine under load) are the only ways to warm up a diesel. I always shut mine off even its a 1 minute break. not to mention its a colossal waste of fuel.
@@Taydrum yeah pretty much. when I was working in the truck market selling these diesels engines it was noted in the owner's manual to not idle for extended periods of time. It is best to put the vehicle under load to employ a full break in. That way the vehicle will get up to operating temperature. With new engines it was also noted that towing Under full load is good for breaking the engine in.
Great video Scotty!!!! Thank you. Awesome channel. 👌🏾😉
I’m working in the Dead Sea.. very warm in here so I was always wondering if that’s bad if I left the ac on in the car.
Much thanks for the info
I've seen girls at university sit in their brand new kia or nissans for hours with the engine and AC on in the parking lot. 😂
Or homework/ assignments to do?
Ask the girls to invite you
Major Tom for hours?? Lol
Major Tom
He must have a girls at university sitting for hours idling there kia or nissan in the parking lot with the ac on fetish
Why are the girls there for hours...?
I used to leave my car running 8+ hours a day when I was a courier, then I would go deliver pizza when I got off. I'd get a oil change every 2 weeks (3000 miles + long idle time). If your CC or EM is glowing red you need new spark plugs on its possibly restricted
Your the funnest video ive ever googled for how-tos and stuff like that, i think ill sub to you!
I like your energy Scotty! And those glasses 😎 so cool! Subscribed!
He also forgot the number one ambulance engine failure, cracked exhaust manifolds. Thats why large diesel engines have segmented manifolds to control heat distortion, whereas most gas engines don't and extended idling doesn't provide good cooling. Installing headers eliminates the problem for the most part.
Which is why most traverse engines for front wheel drive have the exhaust manifold on the engine front - right where the fan air can hit it.
Great vid. Piston rings get oiled by sling out oil from the crankshaft con rod big end onto the cylinder walls. That requires some RPM to do, maybe more than base idle rpm. you can lose your rings early in a boat diesel I know for sure with lots of idle time, so bump the idle to at least 750-800 and blip it to 1200 once in awhile just to put oil all through it for sure. Bring it to a dead idle before shifting into a gear. Cars? The great one just said it.
Great advice bro. Will be checking out yer other vids.
Love the picture of the Alaska Railroad consist!
Great vid again.. You crack me up..
Mitch Grooms I agree I I really like his videos.
Several years ago, I returned home from work, pulled my 06 Montero into my driveway. Just then, the mailman pulled up to the front of the house. I put the car in Park and went to get the mail and a package he had for me, forgetting to shut off the car. The next morning, I come out of the house and see the engine was running. The car had been idling for 14 hrs. Remarkably it did not overheat or leak any fluids. Today's vehicles are much tougher than the old days.
Sunil Thomas Indeed I was completing a 13 hour drive in a Chrysler Sebring. Got to a rest stop and fell asleep before turning it off. 9 1/2 hours later the gas gauge had only dropped by a quarter.
Yeah, cars are made to run and its not harmfull to the engine, its actually small amount of load and cars tend to have mixtures with lots of air at ide so it doesnt wash off cylinders like some say, at least for fuel injected vehicles
If your car is properly maintained idling in neutral or park will not cause it to overheat regardless of temperatures. You just burn a bit more fuel. Starting and stopping and city driving are worse on your car than idling or just driving on the highway or freeway.
Evert Guzman Don't warm your car up in the snow without first making sure your tailpipe is clear of snow. Families have died of CO poisoning trying to warm up in an idling car that has an obstructed tailpipe.
Sunil Thomas, I did something similar when I got my new Mazda 6 which had a push button start-stop. For decades I was used to driving with ignition key, park, pull the key out and walk away. Old habits die hard. Returned from work in the evening, parked my new Mazda 6, got distracted by some random thoughts, stepped out of the car with home keys and walked away forgetting to push the start-stop button. Next morning at 8 am found the car still running and low fuel light had come up. It was continuously running 14 hours and I thought that must have damaged the engine or something. Its been 5 years since and put 50K miles, the car still runs like new. Scotty is right one cannot damage these new cars even if you leave them to idle for extended period of time.
I always tell people to open the hood.
As soon as they do the ac runs cooler and temp goes down.
I watch U all the time.
Hi scotty.... I have a question for you.
I have a toyota corolla 1993 4af
In my country is carburated engine and it has automatic transmission the problem I have is.... When the car is in idle speed is 1000 when I shift to drive the idle speed fall to 400 and of course begin to tremble and if I'm trying to park moving the steering wheel is even worst and lights on even worst.
What can be the problem
very informative Sir. keep it up. Watching from the Philippines
Thanks for the support 👍
Nope, but we ride a jeepney most of the time. most jeepney drivers here are reckless drivers. you should watch our bad drivers of the Philippines series,hehe
I am a subscriber from the Philippines too. Hello Scotty!
Sitting in traffic in Manila would be very common .
0011clem raptor hehe you got that right.
Don't forget about modern diesel engines with a DPF. Sitting and idling for long periods of time and not driving and allowing the system to "regen" will plug up the DPF and EGR coolers with unburned soot. The newer Cummins will increase the idle speed when idling for long periods of time to try and compensate for this, but it can only do so much, it needs to be driven to regenerate properly.
RedneckManWV99 this is not a problem as long as you remember to drive the car hard sometimes and make sure to let the DPF regen properly. At least not in european BMW:s, we've had 6 BMW:s with no issues with DPF, they were taxis and run idle constantly even during winter. Only one had a slightly clogged up DPF, which was cleaned without issue and did not need replacement, this was after 200 000 kilometers driven (mostly in the city), i don't even want to know how many hours it had ran idling (i can tell a lot). 7th one going strong at 89000 kilometers, except for Adblue pissing into the SCR catalytic converter too much and the dealer/factory having to replace the whole exhaust system + the adblue injector... Adblue is bullshit. Still waiting for those replacements, warranty will cover, but it takes time to get the parts.
Whenever possible, i drove the cars hard, when the engine was warm and the speedlimit wasn't too low. Driving a modern diesel hard occasionally keeps it healthy as long as you remember to let the DPF regenerate completely before turning the engine off.
I have an older truck 2005 with no DPF but the guys I know with newer trucks replace the exhaust system from turbo back and tune out the DPF and EGR. They get better fuel economy afterwards and it sounds like a Cummins again.
Best thing to do IMO. As long as your state doesn't check emissions! Luckily mine doesn't.
RedneckManWV99 I unplugged the EGR on my pre-DPF old diesel truck. No codes show up and oil stays cleaner. NC is the same way, diesel exempt from emissions test but gas motors are subject to it.
on our peterbilts at work we have the dpf filters cleaned once a year when the truck goes in for inspection.
Love the australian ford falcon gear shifter snuck into this clip 👍
Wow, I these videos are really well made. Thank you for the information good sir!
I have a 2000 dodge. Idles forever and has 455,000 miles. Runs great. Use Lucas and change engine oil when needed or sooner.
Lucas for gas or oil?
@@zoezzzarko1117 oil
@@johnricciojr.5324 ah ok thanks! I used to use the lucas for gas all the time and my car loved it. I didn't really know what the oil product does....
I could never do a cold start and go, I always let it idle till it smooths out, usually around 800 RPM
Same, my 04 mustang and 02 camaro are nice enough to let you know when they’re good to go after starting
You're right, the car will calm down within a min of idle time then its ready to go. Good rule of thumb
lol mine idles at around 500
Kronx 6.0 too huh? Lol
I just go. Never had a problem. I mean unless you own a mclaren or something I can understand but just a Toyota or Honda never saw the point.
I have an 02' Chevy Blazer and it has a HUGE fan attached to it that goes to the pump directly and doesn't stop, it keeps the engine plenty cool!
I liked the video before it started and wasn’t disappointed by the end of it
Thanks for the very useful information scotty!! :)
thanks for the support!
Thanks for this. I take a nap for 30 minutes in my car, at lunch when I'm at work. I run the engine and AC.
Pelt Down Posse same bro same !!
here is Kanada.. we are having the worst stupid winter ever.. it's between freeze your butt off or it's raining .. the roads are attrocious..it's dangerous.. even the ski resorts have no idea what is happening..
but when it darn cold..i let my car run 3-4 minutes before i take off.. my honda doesn't sound right when i leave and it's cold as ice..
and besides..i have to let the ice unstick from the windows in order to break it off..otherwise, i snap my wiper blades..
after 215 k's .. still running well .. 2006 element
Glad to see the man reference the auto-stop system
