As a retired mechanic I was glad to hear you recommend a oil change after the break in period. I have always done one after the break in period but was shocked by how many metal particles came out when I just changed the engine oil and filter on my new 2023 4runner. I was really surprised and happy that I had done a oil change. With all the modern machining and exacting tolerances you would think everything would be pristine, especially since the 4runner is built in Japans factory that is known for being one of the best.

[@user-tb7rn1il3q]

New engines, even well made ones will produce a lot of medal during break in. Since the rings aren’t fully seated you will also get a lot of gasoline and carbon in the oil as well. This is why you dump the oil at 3-4K miles for the first oil change. Many do it after 500 miles.

[@AnalogWolf]

The way I see it is this: the piston rings have to have a slight interference fit to ensure proper compression and lack of oil consumption, etc. By definition that means you'll get some wear early on as the rings seat against the cylinder walls. I also believe that is why the break-in period wants you to avoid high speeds, long periods of driving at constant speeds, etc. Flush out those shavings caused by the seating early on and you should be good.

I bought my first Honda Odyssey back around 10 yrs ago, one day I was attempting to change the driving compartment filter. When I removed the glove box, I discovered that the steel bar that is installed as part of the assembly procedure when the dashboard is installed at the factory, was still in place! I’d purchased this as a used vehicle from the same dealership that the original owner had, and I had every service item noted in the included manual that had been performed over the years. Twice! Two times the owner had brought their car (my odyssey) in for something, and 2X it was listed as having been part of the service claimed to have been paid for. The filter, was packed tight with dried leaves, bugs etc. I had to use a vacuum and my air compressor to get all the accumulated sh/t out of the system before I installed the new air filter. Now when I go for either a new (used) car or gave my car serviced I inspect the work immediately afterwards. Don’t blindly trust the mechanics anywhere. Find someone who is good and has the highest level of experience as well as integrity and stick with that person

I don't think that's a bad idea for any new vehicle. You never know if something was overlooked and there is debris in there. I know the filter takes care of that but I've always done it just for piece of mind as well. It's not going to hurt anything, so why not.

[@ericfranke1637]

@@anvilsvs these days there is no such thing; the factory oil is the intended oil for the car. It's just that you will accumulate more wear metals and get more fuel dilution in the early stages that is best to get out. It's also good to get the silicone out though that is less harmful.

Very good videos! As a retired travelling salesman, I have a suggestion for anyone who has a breakdown when travelling away from home. When you need to find an honest, capable repair shop call a local auto parts store (locally owned is best), ask the manager for his recommendation, where he takes his own vehicle. Shops are his customers, he knows which are honest.

[@curtismmichaels]

I appreciate these videos. I hope you continue addressing potential myths. It's a great way to get an education about my car in bite-sized pieces. As to marketers making maintenance policy. I place that beside lawyers writing medical policy. I get the need for the guidelines in both cases, but I want them made by the professionals who actually know what they're setting policy about. Engineers and Doctors, not marketers and lawyers.

[@The_Noticer.]

About the start-stop, how about the scenario in Europe with very small displacement turbo engines (1.0liter 3cylinder), high boost (>120bhp per liter) that has start stop. So you are in city traffic, rev up the turbo and then the start-stop shuts it off again. Doesn't that hot turbo eventually build up more carbon and wear because it cooks the oil?

[@jamescaron6465]

When I lived in the Northeast, I always let my vehicle sit for a minute or two before I drove off when it was really cold out. Mostly I did it because I wanted a toasty warm vehicle but mostly I just wanted the fluids to circulate and warm up a bit before I got it going. I’ve always followed the breaking procedures and yes, I always short cycle the very first oil change at about 10 to 1500 miles I figure it may not need it but oil is cheap and engines are not.

I'm and Engineer and a car maintenance fanatic, and here's my very short story: I couldn't convince or stop my father from doing and/or adding all kinds of things to his vehicles. Examples: "fuse kept blowing so I wrapped in tin foil" (true story); "Just add some STP to it. It'll stop rattling" (true story, and he was really ticked off when the emissions roadblock people wrote him a fix-it ticket because his old Chevy wouldn't pass); "Just pour a can of trans fluid in the tank. It'll clean up those valves" (yep - saw him do it a 100 times); "Got a radiator leak on the way back from xyz. Stopped on the way home and dumped a can of ground pepper in it. No more leak." (yep - at least he didn't use the old farmers fix this time: an egg). And the good news is he never set a vehicle on fire or did any damage that wasn't correctable, perhaps at a little more cost though. He grew up during a time period when few people even had cars where he lived, no one he knew had electricity, the outhouse was out back and Sunday was bath day.

Another great informational video. Information is key. I’m retired now but was an ASE tech and shop owner with three employees for 42 years. I don’t know how many times I stressed to my customers “Read your manual and don’t listen to the salesman who sold you the car “ . A car is a very large investment for most people and they need to know what they should be doing. These 10,000 and 15,000 service intervals and “ Lifetime fluids “ are basically under laboratory conditions, no stop and go, no extended idling, no short trips, no hot, no cold, no mountainous driving etc. Which is basically normal use. Even if you somehow achieved that optimal condition there are still Maintenance items that you’re supposed to be doing within that extended interval. Even down to monthly checks, tire wear and condition, fluid levels ( even on expensive cars not all fluids are electronically checked), lights, wipers etc. A looked after car is a happy car and a happy car makes a happy customer. Keep up your good work and informing the people. 😊😊

FAO Amd - great channel, great ethics. I have some things I was taught in UK for your next Myths or Facts: I was always taught, ideally, to get the car moving a little before turning the steering wheel to avoid unnecessary wear on tyres/suspension/steering components. On a hill, always select neutral, apply handbrake, release footbrake to allow handbrake to take the weight of the car, then select 1st gear/park and shut off engine . . . so no strain on transmission. After a long motorway/highway driving, allow the engine to idle a few minutes before turning off to allow fluids to cool/circulate turbos/engines etc. Never rev engine past 3,000rpm until about 10mins of driving done. If your car fails to start 1st time, let 30 secs go by before trying again (reduce damage to starter motor which might otherwise not have stopped spinning) Switch off all lights/wipers/air con/heated rear window etc. and allow the car 30 secs to recharge the battery before shutting the engine down for the night. Especially in winter. When going downhill, select the appropriate gear and have the engine doing most of the braking for you to maintain the posted speed limit. For example, 3rd gear, engine sat at 3,500rpm going downhill and moderate use on/off of the brakes so the brakes do not overheat/fade when you REALLY need them in an emergency. See what you make of these, mister. Cheers Mike

On the radiator fluid leak stop. We had a radiator leak in my son's old pickup. We used the leak stop. This in turn caused the raiayor to clog up and the engine would often overheat. We eventually just replaced the radiator. We were told by the machanic that the leak could have been fixed but the radiator was ruined by the leak stop stuff. Basically, like you said it would do, the leak stop clogged up the radiator.

[@thechuckster6838]

Excellent video! I'm old school in the sense that I properly break in any new car that I buy. In addition to what you have explained, the brakes need to break in as well. I've seen folks start the car and immediately put it in gear and take off abruptly in the middle of winter. I push the auto start button on my remote 5 minutes before I leave so that I'll have a little heat in the cabin so I don't freeze my nuts off. Thanks for letting the general public know the importance of break in periods.

Another great video. Especially liked how you bought up the "lifetime fluid" myth. The lifetime of the warranty period I'd suggest. For example in my Country at least, Nissan does not specify a CVT fluid change in any of it's scheduled services. They have a 5 year warranty. Mitsubishi on the other hand does specify a CVT fluid change, and they come with a 10 year warranty. The same Jatco transmission, two different company philosophies. Moreover it's rare here to find a Mitsubishi with a sick CVT but common with Nissan. Hope to see you do more of these myth busting style videos.

[@Drmcclung]

As a seasoned mechanic myself, I REALLY appreciate another fellow seasoned pro brining up engine break-in, so thank you for that! Sometimes talking this topic over with customers is like herding cats! I might be able to help with my own 2 cents on the engine break-in period; I do notice a lot of confusion and conflation coming from mewbie/amateur mechanics, mostly from the 'old car' clan, who hear about the flat tappet cam thing (this is 100% true, and you really shouldn't be using new flat tappet cam setups for daily street driven muscle cars today anyway, leave those at the drag strip. Spend the money on a hydraulic roller cam).. and the same guys will state (incorrectly) that anything with hydraulic roller lifters doesn't need breaking in at all (that part's true; for the valve train, but not the rest of the modern new engine or even a freshly machined old one). But they don't account for or sometimes even understand that pistons, bores and piston rings in any piston engine from any era, that's still gonna need several hundred miles to for their lifelong marriages to form, so to speak. So yes, break-ins are still 100% relevant across the board, just not for the same reasons across the board. However, what we could sit and split hairs on all day is for how long, the "proper" procedure, and the actual processes happening inside the engine.. That one can definitely go on ad infinitum lol

[@mplslawnguy3389]

With the Hemi, after a short conservative break-in period, you're actually supposed to go full throttle while cruising intermittently for a few hundred miles. I would assume that this is to set the piston rings. I wouldn't call myself a mechanic, but I've always taken it easy with new cars, but my Ram with a Hemi was the first one I've seen that actually tells you to floor it for a period of time.

I have one comment on the use of the start/stop system. There is one thing that was not mentioned in the video. Turbocharged engines. If the engine is very hot and has been heavily loaded the start/stop system can damage the turbo. This is a very unlikely scenario, but the start/stop will prevent the turbo from being cooled by engine oil by immediately shutting the engine off when the vehicle is stopped. For example, when driving long and fast on the highway and stopping at a gas station.

[@floggyWM1]

if you stop at a gas station, you have to turn your car off anyway. If you want to idle your car after you stopped after long periods of time, you just put it in Park and let the car idle.

In some rare cases, engine oil stop leak might help. I had an awful 1987 Hyundai Excel with 130k and a bad oil leak (these cars rarely got 100k miles back then). Mechanic said it would be too expensive to repair. I was broke, unemployed and needed a car just to get to job interviews. I used engine oil stop leak and it stopped the leak for about another 8k miles. Just enough to get to job interviews. Finally got a job about an hour away, and about a month into it, driving home at 70 mph on the interstate, the engine blew up. I don't think I would have gotten those crucial 8k more miles without it. Since I had a job, I was able to qualify for credit to get a better beater car. I don't miss that car at all! Awesome video as always, AMD.

Great advice from a mechanic who cares about his customers cars. I have always broken in my new cars and changed the oil at 1000 miles. This used to be a warranty requirement, but today along with the crazy lifetime fluids is not in your cars best interest. Re Stop/Start, i hate it and refuse to buy a car where you can't disable it, this rules out a number of modern cars for me, but i just refuse to accept that it saves anything, and it wears out the starter motor far too quickly, infact stop/start driving also wears out your car more quickly.

I had a partially blown head gasket, added the additive, and it stabilised the temps

Warming up for the transmission’s sake is so true. Even on my manual car I could tell the difference in shifts between cold and warmed up. It is more apparent on automatic transmissions because you can tell it doesn’t shift as well. So, yes warm up the engines before you drive.

[@mj8495]

And just drive gently, especially in winter, for the first 10-15 minutes...😊

No mention on whether or not, or when to use High Mileage oil... I enjoy every video. Keep it up. If our 2009 RAV4 ever developes a cold start rattle I'll be looking to bring it to you. Looking for your review of the new Toyota Grand Highlander.

I have added power steering stop leak in my 1990 Volvo 240 because there was fluid in the tie rod boot when I did the replacement. Let me tell you that immediately my steering was acting up. Turning lock to lock it would bind and stick. I have flushed the the steering once again with fresh fluid to make sure that product is out of there. It took few days to return to normal. I will never use any stop leak anymore and rather repair the issue.

[@redneckdave1968]

I've been in the automotive business for 38 years and I now work for a large chain auto parts store. I know all about what you address in your videos part 1 and part 2. I try to educate my customers to help them learn how to maintain their vehicle. I'm in the business of selling but I won't try to sell someone something that they don't need just to make a sale. I take my Highlander to the dealership every 5,000 miles for routine maintenance. I know you don't have to do that if you know a reputable shop that will treat you right. I trust the dealership because they haven't tried to sell me something that I don't need just to make a sale and my dad works there so I get a discount for my service. Thank you for making these videos so people can learn more about their vehicle and not get suckered into paying for something that they might not need. Keep up the good work 💯👍

[@voterdown]

👍 a lot of common sense but good to hear an expert mechanic clarify things. Like care of any other machine, a car needs proper maintenance in all areas you speak about. Changing oil on a new car after first 1,000 miles just makes logical sense, as well as going easy on the driving for first couple thousand miles. It’s a machine, take care of it and it will give good long lasting service.👍

Hi, I just learned how to remove a sealed electrical terminal for my Toyota fuel pump. Nice to be able to add this to my abilities. Now crimping and installation is obvious. ☺

[@williamthompson9508]

So glad you brought up lifetime fluids. That is the biggest pet peve of mine with modern cars

[@RealWorldGarage]

On warming up you just don’t want to do extended warm ups no more than say 5min max. I live in the south where the heat is extreme and don’t personally use the start stop technology. I was hoping you’d do the life time fluid question, no such thing. Break in is just take it easy like you said the first 500-1000 miles. And change that oil at the end of that break in. On these additives to stop leaks it’s a Hail Mary pass on a 20yr old hooptie that’s at the end of its life cycle, if this is a car you’re wife/kids/family is relying on, FIX IT CORRECTLY. BTW these comments I did as you went through the video!!! Good stuff as always, stay blessed my friend!!

[@perryallan3524]

I have had several mechanics tell me that the "stop leak" products must only be used as a temporary fix until a proper repair can be done - and he fluid should be changed and the system flushed within 1 month (max) of adding the "stop leak" product. Essentially, they told me that its a way to keep the car driveable until they can slot it into their shop for work - and then I will need a system flush as well as any competent replacements.

@TheCarCareNut. Hi, AMD. Here is a debated issue, please consider it for a future video. Does it hurt an automatic transmission to shift from reverse to drive while still moving? That is to say, must a driver come to a complete stop before shifting directions? Thank you kindly. 🚙

Start/stop is the most useless thing on a car.

[@S_Paoli]

useless I don't mind.... I would describe it as annoying, aggravating and DANGEROUS! I have a brand new BMW. When I'm stopped at an intersection waiting to turn, sometimes I floor the gas pedal and the engine takes half a second to fire up. Half a second may not sound like much, but at a busy intersection, it's scary when the car isn't moving because the stupid engine auto stop/start lags. (turns out that all of the owners on the BMW forum are reporting the exact same experience... and guess what? BMW says it's "normal"... and there is no way to disable it permanently. You have to remember to disable this "feature" whenever you start the engine.

[@williamtoney2599]

Amen! But you can buy a small short harness that plugs right in that bypasses the start/stop feature. Money well spent…..😊

Thank you AMD for your videos. They are very informative. I have a myth question I’d like to ask you. I own a 2023 Tacoma V6 and was thinking of installing an oil catch can. Most people I talk to say they really don’t do anything to prevent oil/carbon build up on the valves. What do you think? Thanks and keep up the videos. I love them!

[@layzbaguette8340]

the purpose of a catch can will always be beneficial unless you are concerned about a vehicles warranty or the price you’d have to pay to get one installed unless you do it yourself.

[@metzmatu8409]

Most modern cars do have baffle call separator that stripped oil from vapour that pass through the PCV. Catch is not really needed.

I used to have a Camry Hybrid which had a lot of Start-Stop. After driving for 530,000km, the Starter was perfectly working fine even though it is probably the most overload part. Of course, the engine was still running fine too.

[@notsureyou]

From memory the starter motor type system on a Camry Hybrid, Is different to the starter motor set up on a non-hybrid.

[@shiftfocus1]

Toyota hybrids do not have starters. They use one of the motor-generators in the transaxle to start the ICE.

Not only that, but they use the hybrid battery to start the engine. The 12 volt accessory battery just turns on the computer modules. @@shiftfocus1

Buy the road hazard accidentally run over a nail on the sidewall at whatever mileage you care to find out then take back to salesman to claim your road hazard and see how many tires he replaces on your car and you will have your answer.

[@michaelbassett5105]

@@JohnnyUtah9173 yes that’s correct if all four tires need to be replaced you should replace all 4 tires. It doesn’t always happen that way sometimes you only need one. The salesman will tell you to replace two at a time. Because they sell tires and selling two makes them more money than selling one. If it was a safety issue they would replace two at a time under road hazard but it’s not they only replace one so they can sell you another one.

I am victim of the "lifetime fluid" myth. I am getting ready to change the transmission fluid in my Toyota FJ cruiser at 58,000 miles. My local mechanic did not want to mess with it (he did not want to be on the hook for a transmission if something went wrong). Local Toyota dealership refused to do it. Luckily, I know it is BS, but it pisses me off that Toyota dealership refuses to acknowledge it.

[@mygolfballsannoy]

Yup

[@njsongwriter]

Show the dealer the part about changing the fluid being required under certain circumstances.

[@bradnail99]

I had a similar thing on my last car, also at 58,000 miles. My independent mechanic refused to perform a fluid and filter change on my transmission. So I did it in my driveway. It made a difference and I drained and added fluid two more times over the next few thousand miles to gradually (and that word “gradually” is important!) clean out the crud from the many fine passages. This was a CVT by Nissan, which are known to have issues. It required patience, but the result was a return to full performance. Had I known earlier I would have done the service at 30,000 miles and every 30,000 miles thereafter.

@@njsongwriter even my mechanic said no.. just bought a used 40,000 mile car.. changing all the fluids.. and he said cars are better now.. not necessary 😱 just wow.. On my 88 ford escort..

Yes, either that or just "True" or "False" regarding a particular statement!

[@flagmichael]

Historically, "myths" have been popular stories that may or may not be true. After all, a lot of what we know to be true or false now may be found to be the other sometime in the future. There is a surprising number of myths people still believe to be false, notably the existence of narwhals. In the early 1800s if you believed in gorillas you were a fool; in the late 1800s if you believed gorillas _didn't_ exist you were a fool.

I call BS on the "Start/Stop can't cause additional wear/tear or damage". There's sooo many people that had problems with their cars that had the feature. That's why it's such a common thing to get these systems deactivated by a machanic or dealer, if they don't have that option on board.

[@handle-this-cock-youtube]

Recently got a new car and overheard a lot of comment that the break-in period isn't really a thing anymore. Despite this, it was my first /brand new/ car and I treat it like a baby. 1,500 miles came around and I changed the oil. Didn't see any metal particles and the oil looked clean, but I'd say it was worth doing. Now that car is stuck at a body shop because someone ran into me in a parking lot. So much for being careful
