So now that i'm the official owner i've already had to replace the front left turn signal which im glad was actually fairly easy, and a bolt on the inno fairing. Next up on the list is an impending oil change. I've done my google searching but am curious to know what people in our local climate are into. I'm approaching 6K km on this current oil, and my friend told me it is currently motul 5w-40.
I know the manual calls for 10K OCI's but of course i don't mind doing it sooner. Some of the oil i have been a fan of in the past using, Pennzoil Platinum in the s2000, and german castrol 0W-30 has always been good too. I see that pennzoil Ultra is on sale right now for $31, and theres actually $10 online rebates to be had...great price for that oil, but it only can come in 5W-30. I tried to lookup some UOA's for it and only finding some older stuff and on WRX's. Anybody here running PU 5W-30 and for how long, would it be an acceptable oil or should i stick with a 40 weight? Also...are STi's picky about filter? I've read about getting the RX8 filter, i don't mind doing that, or just going with an M1 filter, or OEM etc.
