    breaking in the engine

    Just curious, does everyone here wait until after 1000 miles to go a bit harder on the engine. Im not saying I want to beat on it but im just curious about what to do.

    I did. I read the manual cover to cover in the meantime. Just me.

    There are competing schools of thought on this. The standard line is to follow the recommended guidelines and play it safe. Hard to argue with that approach, and in the end 1000 miles ain't that bad.

    The second major one is that a hard break-in will actually better prepare the motor for aggressive use, whereas the recommended guidelines are about longevity. I've seen "research" that supports and defies this approach.

    Me ... I took it to redline a couple of times, but mostly ran it under 3k like the manual states. I figure I was preparing it for a long life with some exciting moments.

    Drive it like you stole it. Or don't. There's different opinions and nobody has ever been able to prove either of them wrong, on these cars or any others.

    I tried to follow the 4,000 RPM rule before 1000 miles. That's all I am going to say just in case SOA is lurking on the forum looking for warranties to void.

    I followed the 4k for 1000 miles except for one or two slipups.

    I'm still alive, and I didn't sell the car out of frustration.

    4k for 1000 miles. I did the same break in procedure indicated in the manual for 2 of our cars.

    I was pretty tame but probably hit 6 for a sec once a trip.

    Now that I'm broken in I don't go below 4.

    I drove mine like I stole it and it runs like a champ. this is a highly debatable topic. The manual says not to tho. I just recently had a compression test and it 140, 143, 145, 142. I cram 20 psi down its throat daily. just my .02
