I don’t know how much oil the motor uses because I really only use the scooter once a year at Portland. 🙂 LOL But it doesn’t seem to use an excessive amount. It does smoke and I see that as a good thing rather than if it didn’t smoke, which would mean it isn’t getting any oil. I did think about installing a shut off valve, but what if I forgot to turn it on? Yeah I think I’ll just deal with the trouble of draining the oil reservoir.
