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.

[@Callm3]

We’ve gotten two new cars this year, and although the manufacturer has said nothing about a break-in procedure, I’ve changed the oil on both at 1000 miles just for peace of mind 👌🏼

[@jahmanborneo1343]

Break in should be in the owners manual. In the manual for my 2023 Camry it's one paragraph. Easy to miss in the sea of information.

[@anvilsvs]

Best to leave the factory "break in oil" in place.

[@mplslawnguy3389]

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.

[@matsudakodo]

@@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.

[@matsudakodo]

New oil is always the best oil.

[@stevelesleyp5141]

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

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

[@johneverett3947]

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. 😊😊

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 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.

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.

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.

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.

[@jansehnal177]

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.

[@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.

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.

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 did my break-in oil change at 899 miles. I poured some of the midstream oil (not at the beginning and not at the end) into a black collection pan. It was like the oil was golden pearlescent paint. Full of micro-sized pieces of metal. I also smelled the oil and there was no gasoline odor with it, a good sign that the rings were properly seated on the pistons. My new 4Runner is happy. I hope someone tests the quality of dealership/oil change place bulk oil vs Kirkland, Mobil 1, etc. That might be a myth to address.

[@nigelgreer5400]

Totally agree on the rad weld stuff. Many moons ago, my old man had a leaky rad so chucked rad weld in, That didn't work so chucked another in which did stop the leak. Year or so after that, cam belt snapped. After taking the head off, there was massive build up in all water canals on main block just under the head gasket.

I like the comment about additives that fix leaks. If you think about it, an engine or radiator is mechanical not an organ/organism that is capable of repairing itself. Hence any additive that claims to fix the leaks is doing so by clogging the leaking part PLUS other functioning parts. Common sense you'd think but I see so many people buying these additives.

The leak quickly stopped, and in all honesty I forgot about the problem and traded the car a few years later.

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.

[@worldsails2000]

I believe the lifetime fluid is a result of two things: 1. The government is pressuring car manufacturers to reduce fluid consumption. 2. The auto manufacturers want to lower the maintenance cost so the salesmen can tell you that the car only has $x.xx yearly maintenance cost over the life of the car. Well it is artificially lower because they have increased the oil change interval and changed the transmission fluids to the lifetime fluid.

[@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?

[@OOTurok]

Yes it does. The turbo over heats, because it is no longer being cooled when it's shut down, resulting in the lubricating oil becoming carbonized which can lead to catastrophic failure of the turbo.

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.

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.

One I heard is never let the fuel get below a quarter full. If you go below that the in tank fuel pump will overheat and fail prematurely. True or flase?

[@OOTurok]

True... but not if you run below a 1/4 tank. The fuel is the lubricant for the fuel pump... & will fail prematurely if you consistently run the tank near empty. The reason they say to never go below a 1/4 tank... is because the pump will never be in danger of running unlubricated if you never drop below that level.

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.

I did use a fix for a supposed head gasket leak (cooling fluid consumption and oil getting overflowing) and it worked fine for more than 5K km. It was for a car that was worth less than what a mechanic quoted me for a repair and it gave me ample time to buy something else. As a side note, that liquid doesn't "add debris", it is filled with glass particles that will melt at the leak point because it's hot and fill it. To me it's a perfectly valid short term solution for cheap cars.

Here’s my take on warming up your car in the winter. For me I say yes but you only need 5 minutes not even. The reason I personally let my car warm up when it’s sub zero outside is because I want the fluids to circulate especially the automatic transmission needs a few minutes to warm up. You can also speed this process of warming up by plugging your block heater in that way your engine will be warm and your just warming up the transmission and the cabin. So you don’t need to warm up any longer then 5 minutes.

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.
