Several reasons. Two that come to mind right away are: 1. Blown head gasket
2. Cracked head/block That could be your extreme case. As in my 1991 fleetwood the radiator holds 3 fluids. Coolant/antifreeze, trans fluid, and oil. It is possible that the thin layer of plastic the seperates the compartments has cracked allowing the two fluids to interchange/mix with each other. I had a 96 cavalier that had same issue but it was trans fluid mixing with coolant and not oil, just a suggestion maybe your radiator is At Fault here? worth looking into

The main difference between the Cadillac Fleetwood and Cadillac is size. The Cadillac Fleetwood is usually bigger than the deville but it all depends on the year to determine the difference. In some of the older years like 1984 and before, it was only an inch or two difference in length and slighty different appearance but in the eighties and ninties the fleetwoods were usually significantly longer and a little wider when comparing the two, basically two completely different models.Like in like 1985 as well as in 1995 when the two were very different models especially in size. So the general rule for comparing the two is the Fleetwood is usually bigger specifically in length.
