    I'm new to the board, but from what I've read, you should possibly go 2 oil changes before going to synth for proper seating of the machined parts (?) I changed to synth at 2600 miles, and after reading numerous posts on the subject, I would have waited until my 6000 mile service to change to synth. Just my .02

    P.S. See "coming up on 3k miles, got some oil ?'s" about 3 posts down from yours in this forum...

    When restoring my first "ride", a 71 Ford Torino, I used cut up beer cans as backer for bondo. Theory was, aluminum wouldn't rust, so why not?

    opinions vary vastly on this issue. some say change right after the B/I to remove any unwanted filings from the cycle, some say use traditional oil for the first 2 changes then go to syn.

    there is no right answer. subaru is REALLY expensive for an oil change (at least around here)

    run some searches to get everyone's opinion.

    The general consensus is: wait until the 7500 mile oil change before the conversion.

    This may be irrelevant, but I had a Aprilia Falco motorcycle. Aprilia put in synthetic oil right from the factory. The bike ran great, but despite my careful breakin, it was an oil burner. This is a common trait, per the Falco boards. I really suspect that the oil burning was a direct result of this practice. Conversely, I waited until later in the game to convert my SV650 from dino to synthetic and the bike never needed a drop between oil changes.

    hey scoobysteve

    would it help my case if, on my next oil change (@5500 miles), I went back to conventional oil for 3000 miles and THEN resumed using synth, or should I just stick with synth?

    Thanks,

    Steve

    I would stay with the synthetic at this point.

    stick with your oil, whatever and whenever you pick it

    Everyone disagrees with when to change to synthetic. My personal thought is to change it right after break-in (which I did). I've had synthetic in my old 2nd gen 1995 Eclipse GSX, and it didn't eat a drop of oil for the lifetime of the car (synthetic oil from 1000 miles on). I changed my oil every 3000, and I never needed to add any oil b/w changes.

    The dealer that I got my car from recommended changing to synthetic ASAP after the break-in period and keeping it synthetic for the life of the car. He's a car guy, and he has a ton of cars, all with synthetic oil right after the break in period. He has noticed no increase in consumption of oil for any of his ten or so cars. He has three or four Subies I believe... one of them a 2002 WRX.

    The one thing that almost everyone agrees with is that if you go synthetic, don't go back to conventional oil. That's when things start getting screwed up...
