use synthetics. you want the oil to withstand hot spots in the motor. most conventional oils dont have the HT/HS needed to withstand use in turbo applications. synthetics also have high flashpoints, which is desired.
Amsoil 0w30,5w30,10w30, 5w40
Redline 5w30, 10w30
German Castrol Syntec 0w30<--says "made in Germany" on the back of the bottle. this oil is almost a 0w40 with a high HT/HS. good oil
over on the oil forums, the (GC)german castrol is highly recommended for turbo applications. it always shows great used oil analysis reports. It is farely cheap also. Autozone is running a special on it for 5 quarts and a Mobil1 filter for $25.99, limit 2 per customer per day. I have already bought up 20 quarts and 4 filters and plan to get another 10 quarts and 2 filters today. normal price is $6.39 a quart and $10.99 per filter
