2006 Kymco Bet & Win 150 motor scooter
1qt Shell Rotella T6 5W-40 Syn
No Oil Filter (the scooter is not equipped with one)
Previous fill: Mobil 1 Racing 4T motorcycle oil.
As this is a belt-driven CVT, the scooter doesn't share oil with the transmission and so doesn't need motorcycle-specific oil meant for shared sumps. The Rotella seems to be pretty stout stuff based on VOA/UOAs, so I'm confident it'll hold up well. After that, I have a quart of Mobil Clean 5000 10W-40 I might throw in there. After that...who knows?
