Engine Breakin Period

Page 132 ofthe manual:

QUOTE

Your vehicle does not need an elaborate break-in. But following a few simple tips for the first 1600 km (1000 miles) can add to the future economy and long life of your vehicle:

- Avoid full throttle acceleration when starting and driving.
- Avoid racing the engine.
- Try to avoid hard stops during the first 300 km (200 miles).
- Do not drive slowly with the manual transmission in a high gear.
- Do not drive for a long time at any single speed, either fast or slow.[/b]

You could have found this by searching the forums. Its there, I found it.

There is no break in period.
When cars come in new to the dealership and people have to go test drive them do you think they really care if they ride the piss out of it, and they end up just fine.

My car was never test driven by anybody. After being driven off of the truck the only person to drive my car was my dealer when he gassed it up and washed it.

That is completely false. My car had 3 miles on it when I bought it and was never test-driven by anyone but me. The car DOES have a break-in period, and it is people who can't follow simple directions like "go easy for 1,000 miles" that make buying used cars suck balls.

Word...nobody else drove mine either. I just took it easy for the first 1000 and got my oil changed at 5000. Nothing special.

Someone test drove your car while you were signing papers.....f!cK that.... I would have made them order me a new one.

At that time the wait was unbelievable. I don't think he wanted to wait another 6 weeks or so to get his car.

There's always a break-in period. It's just a matter of how you choose to do it. I have my own methods and preferences.

The biggest thing that I still think is imperative about a break in period is to not just run your first 1000 miles at a constant speed, like 900 miles at 65 mph, and 100 varying. Keep it varied with the rpms and i imagine it will just break in just fine...Also don't be stupid...i know thats hard for some people, but still

my dealer drove mine to get it gassed up and washed as well, dunno if he floored it all the way...

I got to drive my dealer to the gas station. That felt good. I got to see the odo at 1 mile. What a great feeling! I do think that with any new car, you should always ease it in. I think the first 1k miles can really determine how your car will last. Just think, if you drive your new car pretty hard then all those new parts could easily start to break at an ealier time or even cause them to have problems in the future because of what you did in the beginning. It's like anything really... take it slow and then you shall be rewarded!

That has not been my experience over more than 25 years of building street and competition engines. I agree with Motoman, not Toyota.

I do not have the experience that lo bux has, but i happen to agree with Motoman too. The key with all of that is allowing the engine to slow itself down in gear, this is just as important as the acceleration. There is a lot that goes into it. Bottom line though still is, do what you are comfortable with.

i'm very confused

. this is my first brand new car, so i dont know what to do. I've read motoman's tips on breaking in, but i'm afraid that i will mess up the routine. I will probably going to take it easy for about 2000 miles. and make oil changes at 500 miles and 1000 miles.

yeah turbocharged, you're doing it correctly. I've broken in many many engines along the way and doing it like you want to will be fine. I kind of laugh at this "drive it like you stole it" posts i've seen around the net. That's hilarious to do that to a new engine. But this also seems to be a hot issue with people, maybe it's some macho thing, i don't know.. but the key to a good engine break in is being gently and making sure that there is a variety of rpms that the engine sees. Not just one rpm for a sustained amount of time (like cruise control on).. just speeding up slowly and coasting down again is how i always break in the engine, and no slamming on the gas racing..

sounds like you'll be fine doing it the way you mentioned..

I haven't "read it around the 'net." I've been doing it for about 17 years or so. Soft and easy makes an engine that blows oil past the rings indefinitely. Seen it many times. Rings want pressure to seat. Valves want pressure to seat. Pistons want thermal load to resolve the casting or forging stresses.

It's not hilarious. It works. It isn't Internet mumbo jumbo, I've done it MANY times, and I've had friends do the same. The engines ALWAYS make more power and burn less oil. What could be better?

I have to agree with lo bux, I mean you cant say that motoman doesnt have the infomation and stats to prove it. quick question, is it just me or what does you tC idle at..my rpms seem a little low
