The specialty shop that rebuilt my ford f-150's rear end said to use it if I didn't want to see him again. I have not been back and its been 4 years of hard towing of a camp trailer. I can say it stays clean like no other oil I have used.
Hard to know exactly how this will perform long-term, but since I have 100Ks of miles using all manner of AMSOIL products in cars, motorcycles, ATVs, tractors, and small equipment, I also have no doubt this is a top notch oil and I'll likely never have to replace this oil in my Outback again. The peace of mind I get with AMSOIL products and the ability to have extended drain intervals is second to none.
Bottom Line
Yes, I would recommend this to a friend.

Officially my go to diff lube, way better than factory fluid.. changed out diff fluid at 40k and again now, this fluid looked good still, I believe it could've lasted a good while longer.. used on Fj cruiser off reading and towing.. thanks amsoil for such great products

I have replaced all my OEM fluids with amsoil and my Jeep is much nicer to drive. Shifting (manual transmission and transfer case) is smoother, differential whine is gone.
Use this in my 2008 Mitsubishi lancer evo x gsr. Transmission, transfer and rear diff all operate alot smoother than ever before. I am really happy with the product. Not to mention there real easy to pour or siphon.
I have several motorcycles with driveshafts and I use this product for the final drive oil. I prefer to use Amsoil products in my vehicles because of their reputation for developing quality products.
Used after replacing pinion seal in the X. Quieted things down a bit with the howling diff. Can't put a complete seal on it being perfect but it beats the he'll out of one of the close competitors that I tried before. Due to a half shaft running a bit dry and cracked coil spring on that side. When that gets repaired I will know how well it tamed the howl. Efficiency has seen a jump in the limited driving I have done. That I can attribute to the diff fluid.
Used this in our ford edge ptu. I needed a long lasting product as the ptu has very little capacity. Have used this in multiple differentials as well. Good stuff
