Question for you guys I recived a call from a shop the next city over from were I am. They have a 300SL GullWing Benz in the shop (Owners car or owners friends car..whatever it don't matter) Anyway...They drain the oil form the engine sump..but can't figure out how to drain it from the oil tank. I said I would try and find out for them. I have only ever worked on one..and that was to change a tire and fix a few electrical grimlins. Never anything mechanical. My question to you guys..Do any of you know how to drain the oil tank on this car? Do you have to remove one of the lines to drain it? Also during the start up..I assume like anyother drysump car the oil will get drawen into the engine upon start up.
