REO 331 oil

[CHM]

I looked in the manuals section and only saw stuff on the multi fuel and not really the REO 331. Looking to see what the oil capacity is on her so I can buy the oil and change it. Just bought the truck and got her home. Feels like a miss in one cylinder but going to give her a complete tune up and carb rebuild. Starting with oil change if I can figure out how much she takes.
Any assistance would be appreciated for both oil or possible stuff to
check on the miss. She was converted to civilian plugs and wires so they do not look or make the greatest connections. Going back to military issue plugs and wires when I get the funds.

I’d have to check the book to make sure but I believe it’s 9 quarts. It should be listed on a data plate on the right side of your dash.

You need the 1964 TM. It covers both engines. There is also a TM from 1951 that is a single book which is basically an all in one for the Gasser trucks.

Thanks. Is it up there in the TM section. It did say it in the dash data plates.

LO 9-2320-209-12 states 9 quarts, but this doesn't include the oil filter.
