Break in period

[canuck fan]

I have had my Z06 for 1 week after giving up my '01 C5. It is suggested that the car be driven 500 miles at a maximum speed of 55mph. Is this really necessary before I can open it up? Thanks

I just got mine.

I've got 750km now (like 500mi), I'm going 130km (100mi/hr) now.

I think you have to be easier on the brakes in the beginning and vary your speed. No constant driving at a certain speed is important. (not sure why!?)

Take it easy.. and enjoy it! I expect to put a 1000mi miles on the car before I start driving it harder.

damm mine hit 490 miles and i couldnt wait any longer.. I drove her hard a few times. Today i was at 550 miles.. and did one blast all the way to 160! Was fun. She seems drive just fine though. Very smooth. The motors come broken in, they just want you to take it easy for 500 miles so everything meshes well together .. clutch/tranny.motor etc...

When I got mine in September, it had 5 miles on the clock.
I took it out for a test drive with my salesman, and got it up to 90mph.

For the first 500 miles, I never let the RPM's go over 4500.
I would drive for 100 miles, varying my speed in 3rd, 4th, and 5th gears. I wanted the engine parts to mesh good.

At 500 miles I had the oil changed. My engine now has 1000 miles, and runs better than it did at 500.
I'm hoping when it has 5000, it will be even better!
The Z06's are truly awesome, I get a smile every time I punch it!


Bottom line, its not how fast you go, its how hard you push the engine and drivetrain, IMHO.

Good luck with yours.

even to the redline ..i cant help it .

I wouldn't redline the engine right off the bat, but you don't have to baby it either. The most important thing is to vary your speed and rpm as much as possible. While the engine may be ready to run, the drivetrain still consists of a bunch of brand new gears whose mating surfaces have not yet 'worn in'. If you use all the gears, for both acceleration and deceleration, and vary your speed, the gears wear in more uniformly and you get a quieter drivetrain. Spend too much time in one gear and speed and you can end up with a car that whines if it's not at that speed.
