I been searchingr from forums to another forums and Ive noticed that every c32 owner is not sure if they have the right amount of oil in their cars. The only way to find out is through the instrument panel. However on the invoices you get from the dealer after each service you will find different amount of oils being put in. I think the best way to check this is to get a dip stick. Now the question is which dipstick to get, from which car? I would assume SLK32, is this right? SLk32 came with a dip stick part number 112 010 03 72 (is this the right part number?).
