Bought for my 1999 F350 with limited slip. Works as expected.

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.

i use it in my 9.5 mark williams with blown alky 2500 hp chevy and lenco. 6.0 qtr and never so much as ametalic flake in the oil. i change it after 40 passes

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

Used it in a noisy rear,definitely quited down. Also don't get the clunking like before.

Quick easy ordering and delivery, excellent product

Getting a mile per gallon since I used it

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.

I use and Amsoil in all my machines

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

I run this in a Caterpillar D7 great product

I commute 1500 miles a week. Amsoil is clearer at changes than all other products i have used. There is no doubt that it is the best on the market, And I spend less $$$. Will be customer for life.

Gears are quieter and runs cooler I run this in my daily drivers and my old cars example 670 hp Cuda that I road race, I do have to add the limited slip additive for it not to chatter

I needed to change the fluid so i went with AMSOIL because my boss used it in his race cars and swore how great it was and after changing both diffs and transfer case my truck has been getting better mileage.I am sold on AMSOIL and will be changing my whole truck over to it.

One of the best oils around

I have used amsoil for many years and alway been happy with results, my truck has 358.000 on it with no major breakdowns and still going strong,

Used this in transfer case and diffs of a 2013 FJ Cruiser for 30k miles. Vehicle is daily driver and upgraded and abused off road. Stock fluid after 30k was dark and separated in appearance. After 30k with AMSOil Severe Gear, the front diff AMSOil fluid looked almost new with significantly reduced metal shavings. The rear looked only lightly used with once again significantly fewer metal shavings. I highly recommend this fluid!
