So, you just bought a car, something showroom fresh with fewer miles on the odometer than a new pair of shoes.


Naturally, you’ll want to do everything you can to protect this investment. Properly breaking the engine in will do its part to help ensure a long and trouble-free life.

But opinions differ on how this should be accomplished. Some experts advocate performing a hard break-in. This includes a certain amount of heavy acceleration during the vehicle’s first few miles. The goal of this is to force piston rings against cylinder walls so these metal parts can seat before the bores’ honing marks are worn away. Done properly, this supposedly results in an engine that produces more power and lasts longer.
