Allow me to rephrase: F250 driven empty = 13 mpg. F250 pulling triple axle trailer and 14,000 lb John Deere tractor = 13 mpg. Tank-to-tank calcs. Could be fill errors. Pre-gas logging era. But very minute mpg variation just the same.
P.S. Truck totalled about 15 years ago. Cannot retest. Sorry.
Thank you for your valuable time.
