Yes — Bell Scooter can be used only in the final gear section, but not in the engine oil (combustion system).
■ Engine oil (2-stroke lubrication)
Do not add Bell Scooter to the 2-stroke oil tank or mix it with fuel.
Most 2-stroke scooters like the Honda Julio use a separate oil injection system, and mixing Bell Scooter with 2-stroke oil can cause phase separation, poor lubrication, or seizure.
Even with premix systems, it may increase carbon buildup and lead to performance issues.
■ Final gear (CVT drive system)
The Julio’s final gear unit is independent from the combustion system, so Bell Scooter can safely be added to the gear oil.
It forms a durable lubricating film on metal surfaces, reducing gear wear, noise, and friction loss.
■ Recommended amount
Add 5–10% of the total gear oil volume.
Example: for 150 ml of gear oil → add about 7–15 ml.
■ Note
Always confirm the gear oil specification and capacity in the owner’s manual or with a service shop before adding.
