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.

Done properly, this supposedly results in an engine that produces more power and lasts longer.
