Need your professional experience on this topic on the proper way to break-in a new vehicle.
The methods:
1. The standard break-in is using the owner's manual recommendation.
2. Then there are the altenatives that some mechanics a racers employ.
Lets talk about item #2.
Most agree that gears and transmissions require light load conditions for say 500 miles to properly mate the gear sets.
Engine Break-in:
Engine builders say you need to run the motor somewhat hard or the rings will not seat properly.
There is this idea that you should "drive the car like it was stolen." The objective is to seat the rings in the first 500 miles then dump the oil. The recommendation is to run the engine up to 4-5k RPM range (no redline). Then heat cycle, drive the car for say 30 minutes and cool down then drive again. No crusing on the freeway. Here is an interesting link: http://mototuneusa.com/break_in_secrets.htm
I realize that much of this applies to the "old days." Is not the LS1 broken-in at the factory on a test stand?
Please post your experiences and findings. Thanks for you time!
