I have 960 miles on my MY 2005 WRX. I've heard many philosophies on oil chanes. Some of these include (I've eliminated those not physically possible at this point, such as semi-synth at 300 miles)
Semi-synth from 1000/1500 - 3000, full-synth 3000 and on every 3000-5000 miles.
Full-synth at 1000 (may end up being 1500 or so for me), another change at 3K and then-on.
Full-synth at 3000 (keep factory in for a full 3K), then every 3K from then on.
I've searched many threads and I just can't come up with a clear, definitive answer. Knowing my luck there isn't one, but I want the safest bet. I'm pretty sure I know the parts I need, I'll check that later, I'd just like to know the consensus on this issue.
I e-mailed SOA just now. The service manual speaks only of a 3K first oil change, but I've heard differing opinions on this. The dealer, of course, told me 3K as well. I think I may just wait until 3K to complete the break-in process per factory instructions but maybe that's just my laziness talking.
