Hi there!From what I can find it looks like 2.5 quarts.Make sure you check the level.Here is the information I have.Thanks
When changing the oil in Type 1, 2/1600, and 3 vehicles, first unscrew the drain plug in the crankcase (1970-72 models) or strainer cover cap nuts (1973-80 models); and allow dirty oil to drain. The oil strainer should also be cleaned. This wire mesh strainer is held in place by six cap nuts, and should be cleaned thoroughly with solvent. The strainer plate should also be cleaned. The lower part of the crankcase collects a great deal of sludge in the course of 3,000 miles. Replace the assembly using a new paper gasket and copper washers. Refill the crankcase with 2.5 quarts of oil. Tighten the cap nuts to no more than 5 ft lbs. The drain plug (1970-72 models) is tightened to 9 ft. lbs.
