Whats up, Im pretty new at this, Im actually an audi guy and i just switched over to the benz world. I am paranoid about alot of things and im pretty paranoid about this.... i have a 2007 e350 (no 4matic) and is the oil you put in 8.5 quarts? thats what it says in the owners manual and on his computer...thats a loot of oil. But anyways i got the mobil1 0w40 and im not sure if my mechanic put all 9 quarts or 8.5, is it alright if he put in 8.6- 9.0 (up to .5 more)? thanks any info would be great i dont want my engine to crumble.. hopefully it will be alright? thanks!
