85W90 gear oil.
There is no way to check the gear oil other than draining it and putting new oil in. Quadracers don't have a dipstick, just a oil cap.
i kno how 2 check your oil ;D
The Isuzu NPR uses 85W140 gear oil in the differential and you can use chevron starplex 2 grease when greasing the chassis.

5w-30 is the only thing you can use in an Isuzu manual transmission. The way it is designed, if you use 80-90w gear oil, it will burn up the top half of the tranny and the same for the transfer case :)
Check your gearbox level you have an oil leak in your oil injection system or your gear box. The injection oil is lighter than the the gear box.
There are usually no lights or meter for gear oil. In old automatic gear boxes you have a dip stick to check the oil levels. New automatic gear boxes can be a sealed unit, and manual gear boxes you have to open the drain plug, and replace the oil.
The dipstick with the yellow top is the standard for oil, red is trans fluid.
could be burning either gear oil, or motor oil. check for leaks and replace gear oil
Its gear oil
