I can tell you out right they get 24 without batting an eye. my ol' buddy Bob had a `85 4x4 burb that got 24 all day long. drove it every day to work. I have worked on so may its hard to remember, but I know the mileage for a fact. after he died I wanted to buy the truck but his widow wouldn't sell it.
