Just so you know, the "break-in period" for your motor is done well under 1000 miles, and some even argue right off the showrrom floor when you pick up the vehicle and are test driving it, its all ready broken in. This is not 1960. Tolerances are tighter, the cylinders and ringlands, pistons and valtrain are much better than the motors of the past. Your motor is already broken in. Sorry to break the news to you. Now go and beat on your car, or dont. But driving your car like an 80 year old for the first 10k miles is also not good for the motor either. some argue that yo do more harm than good. Why do you think most serious tuners drive there cars directly to a dyno to break in there cars right on the rollers? Its not uncommon.
