Thanks for the info, Just trying to change the oil has been more of a problem than I expected. Dose mercedes make a special tool to get the cap off, where the oil filter goes?
Looks as though I'm already going to have to replace that. I must've cracked it when trying to get it off, which I finially gave up on and just decided that new oil would have to be good enough until I could figure out how I was going to get it off.
