I think multi viscosity oil was fairly new when this bike was made but with an air cooled engine that is screaming at 40 MPH quality synthetic would seem like the best choice. No pressure lubrication on the 50cc engine.
The wife passed me on the way home. Told me the tail light was bright but the headlight was pitiful. I think it's a 20 watt bulb. No night riding on this bike.

I think you will be fine with 40 synthetic, but I would probably run a 30. Rotella T5 10W-30 is an inexpensive and durable synthetic-blend that you should be able to find at an auto parts store like Napa, Advance, etc.
