How do you change the oil on a C280?

First of all you have to warm the engine.Then let the oil drain to the bottom of the oil pan, at list 20 or 30 minutes. Put the car in a flat surface and unscrew the big and only bolt located in the oil pan. Then let the oil goes out. Don¨t forget to put something for the "old"oil. Be careful with the oil temperature. Then make the reverse action with the bolt and tight it well to evoid some leak, it could be dangerous for the life of your engine. At the top and front of the engine , there's a black cap where you have to put the "new " oil. Sometimes it's hard to remove because it has a bayonet system. The 6Lengine takes 7 lts. of oil. You have to chek it out with the oil dipstick located at the right of the engine. Do not overfill .
