I've heard people said that you should let your brand new car (engine) run overnight (like 6-8 hrs), so that every engine component can get all the parts running smoothly. also after like 500-1000 miles, get an oil change so that all it can get rid of all the dirty stuff from the engine.

What you guys think of this idea?

Idling is the worst thing you can do to a new engine. I would never let an engine run as you described. It's a sure recipe for high oil consumption and poor performance.

I won't do that.

There was another thread about breaking in. The idea is, run the engine as HARD as possible for the firt 20 miles, then break in the other 980 miles normally. It has something to do with the rings being sealed better this way. Go find it, it's somewhere in this forum.

Yeah do oil change after you break in. My salesman (and the manual) tell me to give him a call after 1,000 miles for a check up. It's complimentary.

Also, you can break in the breaks, too. The idea is, go up to 80 mph when you are breaking in your car. Then slam the break as hard as possible. THis way you break in the breaks and they'll be more efficient. Do it only once or twice I think. But the hard part is, finding a place where you go up to 80mph then come to a complete stop like that.

I wouldn't do that to bed in the brakes. There are any number of good websites that describe how to break-in your brakes. Try Stoptech's site, they've got a pretty good explanation of how and why, and they do nothing but brakes, they are one of the true experts.

Well, I read it in Road and Track, but don't remember the actual details. If you know how to do it, I don't mind you actually sharing that info.

From Lo bux's link:

"We typically recommend a set of ten partial braking events, from 60mph down to 10mph, followed immediately by three or four partial braking events, from 80mph down to 10mph. Alternately, a set of eleven stops, from 80mph to 40mph, or a set of seven stops, from 100mph to 50mph, would be approximately the same. As with street pads, each of the partial braking events should achieve moderate-to-high deceleration (about 80% of the deceleration required to lock up the brakes and/or to engage the ABS), and they should be made one after the other, without allowing the brakes to cool in between. "




I think I'll pass .

I definitly would not leave my car idle after bringing home from dealer.

HOWEVER... this one time at bandcamp I got smashed at a bar and was in no condition to drive home. So I pulled into a local residential neighborhood and crawled into the back and passed out till the morning. Woke up and WTF??? car was still running w/ the AC on.

Moral of the story: don't drink and drive!

That's some interesting information. I wouldn't know the correct answer cause the tC is the first car I've 'broken'in' myself.
Yah, for the same reason I am taking it safe and just drive and break in the way it was prescribed from the manual booklet.


A friend completely unrelated to this site told me the same thing about the piston rings and he seen photos of how clean cylinders were when they were broken in by driving hard the first 20 miles.

I've taken apart engines broken in Motoman's way, and they are always better. That's why I do it pretty much his way and have been for a very long time.

Leaving your tc running over night will only get it stolen
