Hi!
I just got my Crossfire only a week ago, so I have a gasoline question for all you knowledgeable owners out there.

I know the gas cap says "Premium Only". Gas station has 3 choices. Unleaded, Unleaded PLUS, and Premium Unleaded. Can I get away with using the Unleaded PLUS or do I truly need to stick with Premium Unleaded? Question of economics, ya know.

Thanks in advance.
