The Oldsmobile Diesel 350 was know for having cylinder head bolts stretch and eventually break in the 1978-1980 versions, the 1981-1985 version of the 350 diesel was supposed to be much better, but the bad early years and cheap regular gas killed the diesel V8's and V6's that Olds had developed. This could either be a low milliage 1978 that was well cared for, I have read that you can keep an early Olds diesel alive for a long time but you have to treat it really really really nice, or it, since Olds and GM decided to give diesel 350 owners an extended warranty as an act of sympathy, many diesel owners hung on to their cars long enough to get the better 1981-1985 diesel engine as a warranty replacement for the bad 1978-1980 350's.

This car is a 1978 Oldsmobile Delta 88 Royale.
