Since the new cars should start arriving soon, I thought I would ask the question that will be on many people's minds. What is the best way to "break in" the new engine. I've heard different opinions ranging from drive it like a granny for 1000 miles to drive it like you stole it. Which is correct? Does it really matter?

I've been using this method for a my last few vehicles and I'm a believer!

I always went buy the rule of beat the crap out of it just dont do any standing wots for the first couple hundred and give time for cooling off in between. That and change out all fluids in the vehicle at about 1k.

Now that people are starting to receive their V's, what is the consensus about the break in period? I was mild with my V1 for the first 1000 miles and have had no problems, but I'm curious about other people's previous experience and plans with their new V's.

Personal Opinion - Keep it relatively tame for the first 500 miles, then slightly more aggressive up to the next 500 beginning to spread it's legs. Then have the oil changed about 1K and it's your baby to play with after that. :)

The engine doesn't need breaking in. The reason for the recommended slow break in is for the drive-train gearing.

we had a saab 9-7x get an engine replaced at 4000 miles because the owner bought it in california and drove it back home to NC directly after purchasing it... as far as i know from talking to our techs about that one its not a good idea to run the engine so long. Hard for a short period might be good, but all day long for two or three days is a really bad way to break in and engine and will probably just break it.

My father bought a new '03 Cobra in Ohio and then preceded to drive it to D.C. and then back to NH within 2 weeks. Car is still running strong with even with more boost!
