1999 Deville
I just test drove a 99 deville today and was very impressed by that car. I was told that you need to run synthetic oil in it, do I have to, or is it just a good idea to do so? Does that car need premium fuel all the time? I know those Northstars had head gasket problems, was that year one in which the head gaskets were faulty, if so, when was a good year for a cadillac that didn't have engine problems?
