Gas use 91 octane.

No specific brand, but buy a dedicated motorcycle TWO stroke aka Two cycle motor oil. It needs to be manually mixed in your gas at 50:1/ 2%. Don't buy outboard motor oil for an air cooled motor vehicle!!

The gearbox/clutch oil you need Non Detergent 30 weight. Can find it at the hardware store or at some auto parts store.

I'd you're struggling, order some from scooterwest.com

SAE 30 gearbox, 2% 2 stroke oil in fuel. Simples. You can use semi synthetic 2 stroke, fully synthetic, mineral, horses for courses. Id probably run semi synthetic on an older scoot based on the condition of your engine, age, whether seals replaced etc. I run semi synthetic on a 1987 small frame with no worries at all.
