Mixing AMSOIL With Other Lubes

Mixing AMSOIL Synthetic Lubricants with Other brand oils shortens lube life and reduces performance benefits
AMSOIL motor oils are compatible with other conventional and synthetic motor oils, so there should be no concern over engine problems due to the mixing of our products with other brands. Mixing AMSOIL synthetic lubricants with other oils, however, will shorten the life expectancy of the lubes and WILL reduce the performance benefits.

AMSOIL does not support extended drain intervals where oils have been mixed, and the AMSOIL warranty is only valid if AMSOIL is being used as the exclusive lubricant and is not being routinely mixed with other brand oils.

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