Product Highlights View Full Description

Meets the needs of today's high-tech air- and water-cooled four-stroke motorized scooters. Unsurpassed wear protection and friction reduction for longer equipment life. Protects transmissions and gear boxes. Wet-clutch compatible to insure smooth clutch operation. Provides long-term protection during storage.

AMSOIL Formula 4-Stroke 10W-40 Synthetic Scooter Oil is formulated specifically to meet the special needs of today’s high-tech air- and water-cooled four-stroke motorized scooters, offering outstanding wear protection and friction reduction for longer equipment life and cooler operating temperatures. Its exceptional shear stability provides consistent viscosity protection and additional protection for transmissions and gearboxes, while its friction-modifier-free formulation ensures wet-clutch compatibility and smooth clutch operation. A special anti-corrosion additive package provides long-term protection during periods of inactivity and storage.

Shear Stability
High engine rpm common to scooter applications increases shear, causing conventional lubricants to lose viscosity and reduce their ability to control wear, resulting in shorter engine life. The synthetic formulation of Formula 4-Stroke Synthetic Scooter Oil effectively resists shear, delivering consistent viscosity protection for outstanding wear protection and extended equipment life.

Thermal Stability
Scooter engine operating temperatures fluctuate greatly, especially in air-cooled engines. Formula 4-Stroke Synthetic Scooter Oil resists breakdown at elevated temperatures, maintaining its protective viscosity for maximum wear control.

Transmission and Gear Box Compatibility
In many scooter applications, the engine and transmission and gearbox share the same oil reservoir. Formula 4-Stroke Synthetic Scooter Oil is shear stable and resists thinning from mechanical activity, providing superior protection for transmissions and gearboxes.

Wet Clutch Compatibility
Some scooters employ a frictional clutch to engage and disengage the engine from the drivetrain. In many cases, this clutch is immersed in the same oil used in the engine and transmission. Formula 4-Stroke Synthetic Scooter Oil is wet-clutch compatible. It contains no friction modifiers, offering smooth clutch operation and increased clutch life.

Rust and Corrosion Protection
Scooters are often subjected to extended periods of inactivity and storage, exposing the equipment to internal rust and corrosion. Formula 4-Stroke Synthetic Scooter Oil is formulated with a special anti-corrosion additive package designed to provide long-term protection during periods of inactivity and storage.

Applications and Recommendations
AMSOIL Formula 4-Stroke Synthetic Scooter Oil is recommended for use wherever SAE 10W-40 motor oil is specified in air- and water-cooled four-stroke motorized scooter engines, transmissions and gearboxes that require the following:

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

Engine manufacturers include, but are not limited to, Honda, Kawasaki, Suzuki, Yamaha, Vespa, Aprilia, Piaggio, Benelli, Vento, Kymco, Tank and TGB.

Service Life
Follow the equipment manufacturer's recommended drain intervals.

Compatibility
AMSOIL Formula 4-Stroke Synthetic Scooter Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil's life expectancy and reduce its performance benefits.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS). An MSDS is available via the Internet at www.amsoil.com or upon request at (715) 392-7101. Keep Out of Reach of Children. Don’t pollute. Return used oil to collection centers.

The only oil for my mower!

By 

from Kansas

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I bought a new riding mower and wanted the best oil I could find for it. I found the Formula 4 Stroke small engine oil and liked the fact that it was specifically designed for small engines. This year has been very hot and the grass has grown like crazy so the Amsoil has been put to the test and passed with flying colors. This is the only oil I will put in my mowers from now on.

Best warm weather oil for outdoor power equipment

By 

from Marion IL

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

We use Formula 4-Stroke in our commercial lawn mowing business...45 deg F to 100 deg F. It is proving a great oil, no consumption, engines still running like new, and the oil still looks fresh at the OCI. At the 10w rating, it will be fine for cool weather mowing. I'd use the 0w40 formula for severe winter OPE use.

Great small engine oil

By 

from Somers, CT

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I use this oil in my 36 inch walk behind mower, the snow blower and a permanent outdoor standby generator. These small engines are still full on the dipstick at their annual oil changes and the oil looks clean. All of this power equipment is now 10 years old and they are still going strong. Thanks for making such a great product for small engines.

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I use this oil in my walk behind mower & lawn tractor. One change through the season with about 50 hours on the work horse lawn tractor & the oil is still still clean, I almost feel wasteful when I change it.
However, I know better. I've used Amsoil for the last 12 years & have not been disappointed.
