How do you break in a new car?

Answer 1

The first 1000 miles should be driven with ease to break in the car.

This is UNTRUE!

The honing process on the cylinder walls create peaks which are quickly worn down to create a seal with the piston rings. The spring pressure from the rings is nowhere near what is needed for proper sealage. The combustion process is what expands the rings to conform to the cylinder walls. Good acceleration and deceleration is a must to create a good seal. So, go ahead and accelerate a good amount to wear in that engine properly, just watch the RPM's. The window of opportunity is very small [less than 60 miles for the first 75% of the break in process]
