5W-30, castrol non-synth. no probs.
just out of curiosity for the synthetic guys, how often do you change the oil? Do you get those extended milage oils (10,000-15,000 miles)? and how long have you been using them? srry if this is a bit of a thread jackin...

I use Royal Purple and I still change oil between 3000-4000 miles. No sense taking that chance for a few dollars saved.
after hearing about this i switched to royal purpal from Mobil 1 and change it every 3000K.

Mobil1, Castrol, Redline and Royal Purple ALWAYS get the best UOA's (not that I care a ton about UOA's, they just back up what I've always thought and done) If you really follow the UOA stuff, the German Castrol oil (it looks kinda green) is actually the "best"
For me, it's Mobil1 every 5000 miles... (10W-30)
The only difference between standard oil and extended performance is the amount of detergents in the oil itself... Personally, I use extended performance, and still change it every 5000 miles (or prior, depends on my mood)... In my wifes car, I use Castrol Syntec 10W-30 and do the same, 5000 mile intervals...
