Break in period

Just saw this, new video from Engineering Explained.
Good video for the noobs on here.

I always thought these were "myths"

 

Excellent video. Over 40 years ago I was told breaking in a new or rebuilt engine, transmission, differential or brakes was about heat cycles and stress relief of critical parts and components. Varying throttle during the first 500 miles is critical as well. Pushing any component too far during break in will dramatically shorten the life of that component. In my experience, this advice has been proven true many times.

In the drag racing community the break in cycle is short for obvious reasons. Different parts preparation and assembly techniques are used and in many instances tougher, i.e. more expensive, components are used. The old sayings "run it hard during break in" or "break it in like you'll drive it" apply to drag racing engines and driveline components, but not OEM engines or driveline components. Friends and associates who lived by those sayings have spent a lot of extra time and money on their cars and motorcycles compared to those I know who followed proper break in procedures on cars and motorcycles targeted for day to day use, not racing.

The video merits watching by those who are breaking in a new vehicle.

 

With the 3rd gens 6 speed auto It's easy not to exceed 4000 RPM, so I guess most of got a good engine break in.

 

It's equally important to not lug the engine during break in.

 

I've got 100km on my truck now following a gentle break in procedure. I've been wondering how many of the guys with diff issues followed any break in guidelines. https://www.marlincrawler.com/tech/differential-break-and-care-information or https://www.youtube.com/watch?v=Imoujpk4neg

 

Toyota doesn't offer 500 mile gear oil changes.... sooooooooooooooooooooooooooooooooooo

 

Very true. I was very light footed on my truck for the first 1,500 miles and I have no diff noise at all "Yet". Knock on wood. I read here complains about the diff issues and jump in my truck every day expecting to hear and feel vibrations and nothing.

 

Only thing i've come close to is flooring it up some very steep roads. Rest aren't an issue.

 

My truck is smooth and quiet, no reason to go above 3000 rpm for me anyway.

 

I took it easy and my tranny learned that i was a grandpa

 

Didn't bother to watch the video, because that engineering explained guy is a moron. I've seen him blabber on before about topics he has zero real world knowledge on.

 

ok, watched it.

Only 2 failures I've ever seen on a new car due to lack of "break in". Guy took a Corvette Grand Sport to a road course and fried the pads and rotors. Not sure doing any break in would have helped that. Second guy took a CTS-V out and beat the snot out of it, messed up the rear diff.

But the video focuses on engines. I've pulled engines apart with 100K+ on them. No measureable wear to the cylinder or to the pistons. No excessive blowby or oil consumption.

 

I have a 2017 with the 6 speed auto, and I was being sarcastic.

 

Good video. With normal driving, you shouldn't have to worry about a "break even" period. I've always been told not to worry about breaking in a car, just avoid towing and high RPM's. I would be curious what they would say about changing the oil after the break even period, since I've never seen a manufacturer recommend changing the oil after break in.

■Breaking in your new Toyota

To extend the life of the vehicle, observing the following precautions is recommended:

●For the first 200 miles (300 km):

Avoid sudden stops.

●For the first 500 miles (800 km):

Do not tow a trailer.

●For the first 1000 miles (1600 km):

• Do not drive at extremely high speeds.

• Avoid sudden acceleration.

• Do not drive continuously in low gears.

• Do not drive at a constant speed for extended periods.

 

That guy is like the opposite of a "bro". He is the guy all the bros picked on in high school. He probably runs Firestone's

 

So I can beat the snot out of it? Drive it like I stole it? How many engines did not make it to the 100K because of abuse?

 

I broke mine in according to the manual. Did it help I don't know but why take the risk.

 

Break-in periods are non sense....it's been proven over and over and over again.

 

Can you explain further?
