hi all. i may have posted this before, anyway ,,
get the new and thinner synthetic oils for each section of your running gear. its well worthwile for mpg and service life.
-runs cooler, less friction, lasts longer -the oil and components. rear axle, trans, engine.
double check ujoints, and synthetic grease those when apart. (the HD joints dont have grease fitting, can use drilled replacement).
-there is now a retro-fit to oil lubed hubs for trailers, could be mabe to fit front hubs if one travels the miles, -at least check that frt bearings have been greased+inspected recently -these rigs can sit for years undriven-
make sure all tires aired up properly, esp with cold weather.
double check that front calipers dont drag excessively. -gets worse with heat of driving. -the older chassis would be drum brake, +rolls easiser.
drive at reasonable speeds, if you have an overdrive, we are jealous.
-the deal with control cables is partly friction down the tube, and part sticky flaps/valves. (the newer trucks went to vacuum pots, which can leak, the older trucks had push/pull cables that are stouter and simpler, an idea.-
my 85 is doing steady 9.5mpg now. ok thanks and blessings to all.
