    Come on fuzzy you're too intelligent and helpful to treat a 50yr old man that way on his first post, point him in the right direction.

Classic!! 15.5 in mine, won't put anything less than 89 with a bottle of octane boost...I've ran 87 before, and well..let's just say I'll never do it again..93 or better if you can..periodically I'll throw a few gallons of 110 just to make it purrr better..lol

    Fyi most octane boosters are 1 point each... meaning, 89.0 to 89.1

    I understand when 91+ isn't available, but otherwise...

    Re: Poor Gas Mileage! Help!!!

    About seven years ago, I accidentally put about 10 gal of 92 in my tank. I'm still haunted by it.

    Getting back to the main point, our gas gauges are about the most non-linear ones I've ever seen. OP, fill up your tank, and you won't use so much.
