Hi there, I have a BMW 316i, with 106,000 on the clock. I need to top up the engine oil, although it only had oil put in during its last service in February, it appears to have run out - long running problem. What is the best oil to use? I do think I have a leak of some sort because it seems to run out of oil, but I cant see any on the floor once the cars moved- if anyone has any suggestions they'd be gratefully recieved! Many thanks Jennifer
