Customers often ask if they should use a friction-modifier additive with AMSOIL synthetic gear lube. AMSOIL synthetic gear lubes are limited-slip capable and do not typically require an additional friction-modifier additive. However, depending on the differential’s friction material and degree of clutch wear, chatter can still sometimes occur. The addition of AMSOIL Slip Lock® will eliminate chatter in mechanically sound differentials.
See the October AMSOIL Magazine for more information.
