Nice truck. Nothing special on the fluids. Jack the wheels off the ground and grease those king pins. Looking and your trip MPG wise I calculate it at 6mpg.
A friends father now deceased was in to brass era cars, drove em all over the USA and Canada. Real old school gear head.
He ran an add in Hemings for years selling all sorts of early oil, grease and gear lube. He had cans and bottles, many different grade stickers but only 3 drums of lube. Gear, oil and grease.
Don’t forget the elimination of Sperm Whale oil from industrial lubricants came in 1972. That was a game changer.
