My dad’s last logging truck was a 1968 IH with the biggest, most powerful V8 on the road back then. The only thing it couldn’t pass on the road was a gas station or the 1000 gallon gas tank and pump we had at our home.
Good one. Reminds me of my dad’s old Ford with a 390 engine which burned a quart of oil every 20 miles. But it ran good, and so as this was the 70’s, and my dad was thrifty, he bought a barrel of oil at 0.20 a quart. My job was to put 2 qts in every day after he came home from the 40 mile round trip to the shipyard and back.
