I used gear oil on mine with its first crank-up. -- It did take longer (it smoked for a couple weeks longer than expected at first crank every day) for the rings to fully seat due to the gear-lube, but otherwise, I noticed no other ill-effects. - Mine took about 80,000 miles to fully gain back its previous fuel mileage of 9+ mpg. i am thinking the gear lube may have slowed the break-in process down? because of less overall wear? -- Speculation at best though.

after 300k miles after my inframe though,.. all I can say is daaaamm!,.. it runs smooth.
Still using all the original IFSM components though... likely on borrowed time with the electric lift pump, gear-pump, and fuel system valves, solenoids, actuators, etc. lol - then again, i have always used a 10 micron fuel filter + added big bottle of diesel-kleen once a month to it since truck was new.
