have had no issues. I refill my lower unit when it is cold but this pumps well in low temps. I do this to prevent any water freezing in the unit. So far no water so I can't say how it does. Did break the lower unit at speed and the oil floated well as I was able to use an oil mat and collect a lot of the lost fluid.
Bottom Line
Yes, I would recommend this to a friend.

Poor courier service

The product is good. The delivery was atrocious. It took 1 day to get from Edmonton to Calgary. It took 3 days and 10 hours to get it delivered within Calgary city limits.
I use this in my 1950's J.I.Case tractor rearends. It keeps things quiter in road gear and has made shifting gears smoother. Not to mention it's far superior to any oil they originally had at the time including today.
Bottom Line
Yes, I would recommend this to a friend.

Move over any Shockproof stuff, its not about that. Its about film strength, durability, and gear quietness..... I only put Amsoil in the race car....
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
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.
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.
Bottom Line
Yes, I would recommend this to a friend.

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.
