Short answer: 75W-90 of any stripe or 80W-140. That info specs synthetic, so on an older truck you might want to stick with dino oil in similar weights.

Any gear oil for hypoid gears will work, you don't need anything fancy.

How much? Not sure on the quantity, but it should run out the fill hole. 2 to 4 gallons is a wag.

75w90 and 80w140 are both synthetics. 80w90 is conventional oil.
