So I took the truck out today for a shake down run before we head Friday to Dallas for the C10's in the park. Before I left I topped off the tank to get an accurate miles per gallon reading Here were the stats: Drove 35.26 miles, and then filled the tank with 3.466 gallons, which equated to 10.17 miles per gallon. Better than I thought it was going to do... Most of the time I was doing 75 mph. So for an old big block that is not too bad, was expecting 8 miles per gallon, but was happy to get this result.
