I've never changed my own oil on my 300SL and I'm somewhat confused. I'm looking at a small canister with a plastic screw top. When I unscrew the top, the top of the canister comes off and I'm looking at what appears to be the oil filter. There is a screw with a small nut a couple of inches down, but nothing that looks like a filter. Can someone help me with instructions on changing the oil filter on the 300SL?
