Engine: 40 oz of SAE 5W 20 or SAE 30, API classification SE, SF, SE, or SE/CC
Transmission: 20 oz of 80W-90 API class GL-3, 80W-90 AGMA Class 5EP
Rear end: 22 oz same oil as tranny.

I had the bed off of my Carryall 1 to put in the trans & rear end oil. There is a drain plug and a fill plug on each. Take out both plugs, drain, replace drain plug then just put oil in the fill hole till it runs over and replace that plug. I used a piece of tubing to slip on the little oil bottle nipple. Still made a mess. A better way would be to buy one of those big syringes that looks like a grease gun. It comes with tubing.

Mine pulls some pretty steep hills no problem. A buddy has a 91 Carryall II with the flathead. We drove it around at a Red Power Roundup (antique IH tractors etc). At one point we had three grown men, two 16 year-olds and their mother on this thing and it chugged right along.
