I just bought a 1993 300SD..... it is unbelievably comfortable. AC will freeze you out, leather seats are fantastic..... engine runs good BUT it does have what sounds to me like a pre-ignition clatter at idle. It also seems to use some oil although I've only driven it 600 miles since I bought it and haven't changed oil & filter yet since purchase. I found with my old 1984 300D, it would sometimes use oil, sometimes leave more than I care to admit on the driveway and other times it would run for all 3,000 or so miles between oil changes with no need to put more oil in it....

I would like to compare notes with some other current 140 300SD owners. Any of you out there???

I cannot find a technical manual on the engine so I don't know how or if I can adjust the injector pump to get the pre-ignition to go away?

Any thoughts, comments, ideas from the other diesel lovers out there?

Thanks,
JMH
