It meets SAE 80W/90, API GL-1 gear oil requirements and is recommended for transmissions on both 4- and 2-stroke motorcycles. AMSOIL MCF is recommended for Honda®, Kawasaki®, Yamaha®, Suzuki®, BMW®, Husqvarna®, Victory® and other motorcycles where 10W-40 or 20W-40 engine oils or SAE 80W/90, GL-1 gear oils are used.

MIXING AMSOIL
AMSOIL Synthetic 10W-40 Motorcycle Oil is compatible with conventional and synthetic motor oils;
however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL motorcycle oil.
SERVICE LIFE
For “on-road” use in engines and transmissions, change AMSOIL MCF and AMSOIL engine oil filter at twice the motorcycle manufacturer change interval or one year, whichever comes first. Change other brand oil filters at standard intervals.
For “off-road” use in engines and transmissions, change AMSOIL MCF at the standard motorcycle manufacturer change interval.
For racing or in engines modified from the original factory design, no change interval recommendation is made. Oil changes are at the owner’s discretion.
