I was wondering what brand of engine oil some of you folks use? Also do you use synthetic or regular oil? I was thinking about switching to synthetic on my 03 CL600 but I think it is over kill. Also since I do interim oil changes between schedules.

Liquid Moly 5W-40 on my W211.

It's more of what spec than manufacturer , and it will contain some severely hydrocracked mineral oil

your car should have always had full synthetic oil...if youve put in conventional oil then it might be wise to clean out your crankcase/etc with something like seafoam/marvel mystery oil as I've heard its not good to have conventional oil in an engine designed for synthetic. using full synthetic is absolutely not overkill on a $100k msrp car

i personally always use mobil 1 full synthetic 0-40
