First look/read in owner's manual. I don't think Kymco fussy on their oil requirements. I use WalMart house brand 10-40 engine oil in my 2019 XTown 300I----works fine for me and has for last 500,000 two wheel miles----rear drive, use Walmart hypoid oil....works
My Kymco book says engine oil (engine) Hypoid gear oil in rear end. Funny as some Honda scooters say use engine oil in rear end,too.
