I really want to buy a used Cadillac 1993-2000 the only problem is the Northstar enginge. It says that they have to take premium gas but that is expensive. Do I have to use premium gas or is that just what northstar says I have to do.
Please be thourough in you answer. Dont say "it says you have to take premium but you really don't" I need facts to back it up. Thank you for all your help.
