About Formula 4-Stroke Scooter Oil

Formula 4-Stroke Scooter Oil is made for air- and water-cooled four-stroke scooters, protecting the engine and shared gearbox against wear and heat.

Before you choose

Confirm your scooter uses a four-stroke engine and allows 10W-40; two-stroke scooters need two-stroke oil.

Can I use car oil in my scooter?

Many scooters share oil with a wet clutch, and some automotive oils contain friction modifiers that can cause slipping. Use an oil listed for your scooter. Ask Jeff for help gathering the right product information.
