My original 1969 1750 owners manual specifies 20W-50, and the reprint of a 73 owners manual specifies "SAE 20W/50 API MS as the "classification" but do mention as "Commercial equivalents" 10W - 20W - 40 from Shell and Esso but 20 W/50 from AGIP. I know I've been using Castrol GTX 20W-50 since forever (probably 69) and always have been happy with it.
