regular oil or synthetic
 

can anyone out there explain the difference between synthetic and regular oil. I have heard taht the synthetic is much more expensive but better. y?

cash.. If you do a search there is plenty of information regarding synthetic vs. mineral oil usage in the 8.

To answer the basic question, synthetic is supposed to be a cleaner better lubricating oil than mineral, thus the higher cost (R&D, marketing, etc).

Is a good thread on Synthetic in the 8 (The similar threads when you are looking at a thread is NICE!)
