Which brand of oil do you use

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.

always do synthetic on the turbo cars . The oil heats up and will cause black deposits which clog the turbo oil passages if you use regular oil

mobil 1 0-40 or 5-40 is mb recommended and cheap at Walmart

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
