Oldsub,,, your statement..joker I wasn't doubting Don's word, but responding to the later post saying thekid1950 should be getting 20 with his pickup.
I never meant to say you were, maybe it was me...lol
you gotta make sure your tank is full when you figure the mileage and full when you feel it up at the end..20 miles to a gal in any old truck is a lot...........regardless of gearing..
but it is his story so I am sure he is sticking to it..lol
my rod will get a good 20 on the hi-way driving at 70 plus, but it also has 2:73 gears..
