AMSOIL Synthetic
Lubricants are fully
compatible with petroleum and other synthetic lubricants.
Mixing AMSOIL with any
other oil, however, will shorten the oil's life expectancy and
reduce its performance benefits. Aftermarket oil additives,
other than those specified by AMSOIL, are
not
recommended for use with AMSOIL products.
AMSOIL does not support extended drain intervals where oils have
been mixed.
