Years ago I bought a 1991 Nissan Pathfinder 4x4 and changed the rear differential fluid. I had metal noise chatter. Found out I needed a slip lock fluid Added Amsoil and within 1 day of driving around town a couple of times, problem fixed. I change the rear differential fluid every 50k miles and always add the Amsoil Slip Lock.
Bottom Line
Yes, I would recommend this to a friend.

No More Grinding Gears!

My '92 Alfa Romeo Spider had the typical grind with 1st to 2nd upshifts, all upshift needed to be slow, and all downshifts were nearly impossible without a terrible grinding. I knew the lube specifications for the Alfa transmission are important and expected the last transmission service was not done with the right gear lube. I added a 4 oz tube of slip lock to the tranny and now the synchros work like a charm. No grind on any upshift and even quick downshifts are smooth, thanks to Slip Lock.
Used this in rear differential change along with the severe gear 75-90 and its amazing at much difference its made swapping to amsoil! Will never again use any other brand in my ss camaro.
used this a number of times.nothing else on the market comes close
Bottom Line
Yes, I would recommend this to a friend.

Used this product for a 12 bolt Eaton posi differential in a 69 Camaro with carbon clutch discs for added insurance with the severe gear 75w-90 weight.
Everything is nice and quiet no chatter at all.
I have full confidence in this additive.
I have to use this with the severe gear synthetic gear lube SAE 75w-90. In my 2016 Power Wagon. I have always used this product in my truck I now have over 120k miles and have never had any issues with my forward or aft differential. Hopefully I'll get another 120k out of her.
