AMSOIL Overhauls Motorcycle Oil Line-up

AMSOIL 100% Synthetic 10W-40 Motorcycle Oil

AMSOIL has performed a significant formulation upgrade and name change to their Metric Motorcycle Oil Series. This line is now called “AMSOIL 100% Synthetic Motorcycle Oil”.

This new line is available in the following grades:

  • 10W-30
  • 10W-40
  • 5W-40 (USA only)
  • 10W-50 (USA only)
  • 15W-50


Why Did AMSOIL Change The Metric Motorcycle Formula?

AMSOIL redesigned the entire line to meet the API SP and JASO MA2 specifications. These specs make this new lineup compatible with the most modern 4-stroke motorcycle engines/transmissions and backward compatible with older models. The JASO MA2 spec signifies that these oils are wet-clutch compatible as well as suitable for models equipped with catalytic converters.

What Types Of Motorcycles Are Compatible With This New AMSOIL Motor Oil?

This new line of motorcycle oils are compatible with all model years and all brands of street, touring, adventure and racing motorcycles. Simply pick the correct viscosity for your model’s engine and/or transmission.

What Kind Of Performance Can I Expect From AMSOIL 100% Synthetic Motorcycle Oil?

First and foremost, expect smoother operation and cooler operating temps. AMSOIL’s synthetic oils are legendary for their ability to reduce friction to improve performance and the riding experience. Also expect smoother gear shifting and a greater ease to select neutral. This product line is likely the most cost-effective upgrade you can make to your motorcycle.

Will AMSOIL 100% Synthetic Motorcycle Oil Reduce Wear?

This new synthetic motorcycle oil series has the ability to reduce friction, lower operating temperatures and maintain viscosity in the face of high heat. This all goes a long way toward protecting your investment. Engine internals and transmission components stay newer longer.

Can This New Oil Be Used In Dirt Bikes Or ATV’s?

Yes, these products would thrive in four-stroke dirt bikes or ATV’s. It could also be used in 2-stroke transmissions. However, in the case of dirt bikes and motocross bikes, we do have the specialized AMSOIL Dirt Bike Oil Series. The Dirt Bike Oils tend to be better choice as the frictional properties are tailored for quick clutch engagement. This is a benefit for explosive starts and quick hook-up out of tight turns. The new 100% Synthetic Motorcycle Oil Series is designed for smoother clutch engagement on the street.

AMSOIL also offers a rugged ATV/UTV Oil Series that is tailored for the rigors of ATV and side-by-side operation.

What Is The Service Life Of This New Synthetic Motorcycle Oil?

The new AMSOIL 100% Synthetic Motorcycle Oil formula is overbuilt for long service life. When used in conjunction with an AMSOIL Synthetic Motorcycle Oil Filter, the oil change interval is twice the OEM drain interval or once per year (whichever comes first).
