Stick with what Mercedes recommends... Mobil 1. We are required to use ONLY Mobil 1 when we do oil services on all of the newer Mercedes. You may end up with oil consumption problems, and fewer MPG if you switch. I'd stick with what they recommend. See your owners manual for more specifics regarding oil use.<br> <br> Tim
Actually if you check your 'Approved Use' manual, there are quite a few oils that are approved. Mobil1, Castrol Syntech, etc. I still stand behind Mobil1.
