I fill with pump 91/93 Octane, and add Lucas Octane BoosterWith all of the new gas pumps when you want 91 octane fuel and the guy before you pumped regular you are going to get about a gallon? of regular before the premium hits your tank. Topping off a couple gallons here and there and you are pretty much running regular gas? Any ideas? What do you guys do to keep the octane up there?
