sure as heck doesn't hurt, generally why people say to change it after the first 1000 is because your engine since it is brand new will let go of various pieces of metal and what not and changing it early just gets rid of that sooner. but i haven't seen any proof that it is better to change it earlier

When I bought my WRX, the salesman told me NOT to do the first oil change before 3k, because the car comes with some kind of special break-in oil. I don't know if the salesman knew what he was talking about, but I played it safe and followed his (and the manual's) instructions.

The special break-in oil is a myth- it's just standrad 10W30 dino- but even if it were, his car is already broken in. Changing it never hurst, but to be honest, you'd probably be fine with another 5k or so. I change mine every 2500 or so, but it takes me more than 3 months to rack up that many miles. I also use full synth, which is god for 7-10k miles anyway in a modern engine like ours.

Oil change
I had the dealer change my oil at 1550 miles. Just had it changed again at 4K. Cost me $22 at the dealership. To corraborate last reply, there is no special, steel hardening break in oil. Suby mechanic said they come with 10w-30w. He also told me that he had to rebuild " a brand new engine, that had switched to synthetics too soon. {1K}". He told me to switch at 10K, independent Suby shop told me to till 15K. When the time comes, I'll probably go with Redline.[check their website, it's pretty convincing]. Anyway, untill then, I'll change the oil every 2-3K or so. Cheap insurance! Sincerely, Collins

synthetic myth?... Why do cars come from the factory with synthetic oil if you cant use it early? whats the difference..It used to be only Corvettes and high end cars that came with factory synthetic, But now even V6 Accords come from the factory with synthetic. Why cant you change it early if other cars have it from mile 1? curious

Definitely a synthetic myth. The Owner's Manual of my new 2004 WRX says that the use of synthetic is fine as long as it's the same grade and certification as the dino oil specifications.

go ahead
It is typiclly a good idea to change the oil after the 1000 mile break in. There are a few reasons for this, but the most important is that, as any engine builder will tell you, the first 1000 miles are the most important to piston ring sealing. This is because for the first hundred miles the piston rings are at their roughest, and the crosshatching is at its most agressive. While there is hardly going to be a cm thick layer of metical particles in you're oilpan or anything, the oil will contain more abrasives after the first 1000 miles than probably any other time in its lifetime. So usually its a good idea to change it out after the first 1000, change at 3000 or so for the first few intervals, and then if you feel like it you can start stretching it out to 5000 etc.
Also, im not sure exactly what goes on at a mass engine production facility, but when you put an engine together youreself, theres one very important step, lots and lots of assembly lube. Im not sure if they even use assembly lube, or whether they run it and flush it (i assume the test run the motors), but if for whatever reason they didnt change the oil used after first startup, you would definetly want too. Since assembly lube is typically a graphite paste used as the only barrier between you're engine and a few seconds of bone dry operation, it's pretty thick stuff, so after the first run you flush it out.
