Just wondering 10cents more per gallon more for premium from 89 Octane. About 20 galllaons per fill up. That about $2 more per fill-up. About 3 fillups per month thats about $72 more per year.

This "investment" does it deserve the best, or is there such a thing as best thing to do in terms of gasoline.

Lear31a, - so regular gas meaning 87 Octane or 89 octane. Would you put any of those cleaners from Valoline etc that clean all your intakes, manifolds etc. How would you keep the internals clean.
