Amsoil Severe Gear 75-90
No luck searching re: a C7 standard differential (non eLSD). Has anyone that has switched to Amsoil Severe Gear 75-90 determined if the Slip-Lock additive is required to prevent chatter? Found information on C5 and C6 but not C7. Thanks in advance. Rick

Amsoil's 75W-90 already comes with friction modifier. Use the Amsoil additive only if you have noise coming from the differential (which I don't think would happen). Using more friction modifier than enough will not hurt your differential, but would 'open up' your differential, making it less of an LSD : )
