Synthetic oil or not?
nov0798, don't appreciate the arrogant answer, if it was in the manual I wouldn't have to ask. The manual states: use approved fluid's.
If you want lots of opinions on motor oil and oil change intervals (OCI), go to the oil forums at www.bobistheoilguy.com That is where the motor oil fanatics are located.

I'm not saying that you are going to do the above, but I just figured it needed to be said.
In our family cars, I personally run Mobil 1 10/30 (129 SL600 and SL500) In the 420SEL I cheap out slightly and use regular Penzoil 10/40. But my dad's Diesel 300TD, he runs 20/50 castrol synthetic, but the oil in that car gets changed on average every 3 years. :p
