engine oil
In reading other threads it looks like the correct oil is Mobil 1 0W-40 synthetic. Is it OK to leave the 5W-30 in there or should I change it to 0W-40?
Check http://bevo.mercedes-benz.com if you want to confirm but I looked under 229.5 but I'm sure it's in 229.3, 229.51 and 229.52 as well.
