    I put it in a 2014 Maxsym 400i. The first impression was indifferent!! After two or three days of use, the sound became fuller and the engine gave the feeling of more power when opening the throttle. I can't do a chemical analysis....I judge by feel and it definitely deserves 5 stars from what I feel from the engine.

    I changed the oil in my four-stroke Kymco scooter and used AMS FORMULA 4-STROKE SYNTHETIC SCOOTER OIL. Previously, I had Motul synthetic 10w-40 and I noticed a huge difference. The engine runs smoother, especially the idle in the morning, the temperature of the engine has decreased, and the most surprising thing is that the scooter gained an extra 5 kilometers per hour in top speed (50cc). Interestingly, a friend with the same scooter also noticed the exact same improvements after using Amsoil. Ultimately, I have decided to use only Amsoil lubricants in all of my vehicles. They are unique with incredible properties, and I regret not knowing about them for so long.

Description & Specifications

AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is specifically designed to meet the unique needs of modern high-tech air-cooled and water-cooled scooters with four-stroke engines, offering exceptional wear protection and friction reduction for longer equipment life and cooling operation at high temperatures.

Its excellent shear stability provides consistent viscosity protection and additional protection for gearboxes and gears, while its friction modifier-free formulation ensures compatibility with wet clutches and smooth operation. A special package of anti-corrosion additives provides long-term protection during periods of inactivity and storage.

Shear Stability

The high engine speeds common in scooter applications increase shear, causing conventional lubricants to lose viscosity and reducing their ability to control wear, resulting in shorter engine life.

The synthetic formulation of Formula 4-Stroke 10W-40 Synthetic Scooter Oil effectively resists shear, providing consistent viscosity protection for exceptional wear protection and extended equipment life.

Thermal Stability

The operating temperatures of scooter engines vary significantly, especially in air-cooled engines. Formula 4-Stroke 10W-40 Synthetic Scooter Oil resists breakdown at high temperatures, maintaining its protective viscosity for maximum wear control.

Gearbox and Gear Compatibility

In many scooters, the engine and the gearbox share the same oil reservoir. Formula 4-Stroke 10W-40 Synthetic Scooter Oil is shear-stable and resists thinning from mechanical activity, providing superior protection for gearboxes and gears.

Compatibility with Wet Clutch

Some scooters use a friction clutch to engage the engine with the drive system. In many cases, this clutch is immersed in the same oil used in the engine and gearbox. The Formula 4-Stroke 10W-40 Synthetic Scooter Oil is compatible with the wet clutch. It does not contain friction modifiers, offering smooth operation and increased lifespan.

Rust and Corrosion Protection

Scooters often undergo extended periods of inactivity and storage, exposing the equipment to internal rust and corrosion. The Formula 4-Stroke 10W-40 Synthetic Scooter Oil is formulated with a special package of anti-corrosion additives, designed to provide long-term protection during periods of inactivity and storage.

Applications and Recommendations

Use the SAE 10W-40 engine lubricant in air-cooled and water-cooled scooter engines, gearboxes, and differentials recommended for any of the following specifications, including Honda, Kawasaki, Suzuki, Yamaha, Vespa, Aprilia, Piaggio, Benelli, Vento, Kymco, Tank, and TGB.

Specifications

  • API SG, SL / CF
  • JASO MA / MA2 (motorcycle wet clutch)
  • ISO-L-EMA2

Lifespan & Compatibility

Follow the manufacturer's recommended drain intervals.

AMSOIL Formula 4-Stroke Synthetic Scooter Oil is compatible with other synthetic and conventional engine lubricants. However, mixing AMSOIL engine oil with other lubricants will reduce the lubricant's life expectancy and performance benefits. AMSOIL Formula 4-Stroke Synthetic Scooter Oil does not support extended drain intervals where lubricants have been mixed.
