Re:Synthetic Oil...Bad?
i don't like synthetic in a turbo car, although it may not 'cook' and sludge up in your turbo, oil temps are usually a lot hotter with synthetic. i would rather replace my turbo than my engine. advanced auto parts 10w40 3.98 a gallon and purolator every 2k. go ahead and waste your money or syn, i'm sure it's doing a lot.

Re:Synthetic Oil...Bad?
be warned, there have been a couple of NEW (03-04) BMW's that have been coming back for sludging of synthetic oil. reason being is if your car doesnt meet a cetain heat it will sludge up in your motor, its nasty and looks like syrup. we have to do a 6 step flush to clear it out.
10w30 synthetic is what i use on my 91. no problems and i dont change it for 7500 miles as honda suggests
unless im raping my car alot.
and for filters go -> i would never use anything BUT an OEM Factory filter. you should cut apart a k&n or pennzoil filer and cut open an oem one, the differences are AMAZING. aftermarket filters have very little filtration.

When I first got my car, I checked the air filter, it looked fine, but I decided to buy new OEM ones anyways, and when I replaced them, what a difference, the oem onw was twice as thick as the ones in there, in my case I would say it was worth the 80+ for the filters.
