IMO, almost any oil today is better than the best oil available at the time your car was built. The only question you might ask is do you want to run multi grade or straight weight oil? There are others with strong opinions on the best oil to use. Using alcohol added fuel / E-10 which is gas with 10% alcohol should have no impact on the oil you use. BUT>.........it can/ will affect the rubber components, fuel lines, fuel pump diaphragms, carb parts, and the list goes on.
