After choosing this for it’s Superior cold flow and long life capability’s for my front axle I have noticed a significant decrease in drag as it now seems a lot easier to coast down hills and so far I think I may be seeing an increase in my mpg

So far very pleased.

I know very little about the product read the reviews and purchased based upon them. I needed a very good product for the front drive on my John Deere 6320 and selected this to meet the bill. I will have an opinion in the coming years based upon this purchase. Only one comment about the price which is considerably more expensive than the competition.

good oil a little overpriced

Running this fluid in my Audi Q5 differentials and my GMC Safari work van. Very happy with the product. Smooth and quiet. Gives me peace of mind

It exceeds my expectations.

first time user of Amsoil. what a difference it makes. did differential service on my 4wd vehicles. they roll allot easier. have already ordered my engine oil and filter for next oil change.

Product speaks for its self

I have used this product in commercial outdrives for over 10 years. Good life and no broken gears in all those years

I replaced the OEM oil in the manual transmission on a 2014 Subaru Outback at about 60K miles. In the cold weather it was difficult shifting from neutral to first and first to second gears when cold. Shifting improved when the temperature increased after driving several miles. Therefore, I cannot recommend this lubricant for the stated application.

Has always served me well in all my vehicles, whether its the engine, (gas and diesel) Transmission, or differential. I have lived in Florida and in Minnesota and have always had the flow needed to keep things lubed.

I run it in everything I own

I do a lot of towing with my vechile, from pulling large wagons such as gravity wagons and livestock trailers. I live in colder climates and never have trouble with my engine turning over hard.

I started using this back in 2008 after speaking to a rep and someone who used the product he sold. I researched all of the findings and found the product to be superior to others.

I used it his gear oil for my older 4 door Suzuki sidekick. And can really tell how great it works, quieter running gears, cooler temps. And last a very long time between changes.

I like all your products that i have tryed and will buy again

I use in my Jeep Wrangler, rear differential!
