Break In Period?

Automatic or 5 speed, the break in period is to not exceed 4000 rpm within the first 1000 miles of ownership. After that, cane it like a vandal! See page 8-2 in the owner's manual.
I'm 373 miles in after today ( Bought on Saturday ).

My dealer told me 500 miles for the break in period. Everyone says 1000 miles which is what im going with to be safe. A lot of dealers just don't know what they are talking about or want to make a sale so they will tell you what you want to hear.

I'm up to 960 miles on a 2004 WRX. I didn't fully follow the break in recommendation. I've gotten it up to 5 or 6k about 20 times or so (mostly after 600 miles). Drive the car like you plan on doing, unless you drive fast and in a furious manner.
I'm going to change the oil this weekend, staying with natural oil. After that I'll switch to Mobil 1 and a new filter at 4000 miles. Why am I changing the oil after 1000 miles??? Because the first 1000 miles will have the most junk in the oil.
Modern cars don't need a break in as much as ones from the past.

When I get my WRX I'm not taking chances and am going to wait at least a 1000 miles untill I whip the baby. I think it's fun anyways to have to wait because then it builds your anticipation to a breaking point.

Hey JMRQ. I read an article about waiting to switch to synthetic. It basically said that the minerals and whatever else are in the dino oil are crucial to your engine in its' early life and that you shouldn't switch until around 7 or 8k miles. I don't know how much truth there is to the article, but it seemed logical. Just thought I would pass that along.

Modern engines do indeed have a break-in period, see this page. You don't haev to worry about your tolerances like older cars, but the rings do need to b seated in the cylinder walls and the crosshatching scrubbed off of them. This means SHORT periods of high rpm use are ideal, but do NOT le your engine get very hot, or thermal expansion will cause your car to break itself in too fast and become old before it's time.
