It depends what kind of truck it is. Some of them will use 80-90 gear oil while others will use more traditional 75-90 weight oil. Consult the manual that comes with your car.
Just use a regular 80-90 weight
PW 80 is a 2 stroke. It does not have oil in the crank case. I think you mean transmission oil. I use 10w40 engine oil in mine and it works great.
About 0.63 quarts or 600 ml of gear oil. I would use SAE 80 W gear oil.
