Hi there, I just purchased a 1999 olds 88 with 63000 mile’s, can anyone give some pointers on this car, for example: fuel octane, oil amount (I think it takes 5 qt’s) is syntactic oil better? And other things that would be helpful.


Thank you

Welcome to AF, follow the owner's manual, if none, 10/30 oil your choice, 4.5 qts with a filter, 87 octane will do it. Without knowing the service history tough to recommend anything else. Keep your eye on the coolant level, these engines were problematic regarding upper intakes failing and to some degree lower intake gaskets.
