    good stuff
    By  WILLIAM,  a  Verified Buyer  from  maryland  on  November 13, 2022
    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.

    Bottom Line
    Yes, I would recommend this to a friend.

    Antique tractor? This is for you.
    By  MICHAEL,  a  Verified Buyer  from  Wisconsin  on  October 14, 2022
    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.

    Synthetic Gear Lube
    By  DENNIS,  a  Verified Buyer  from  Iberia, Missouri  on  October 11, 2021
    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.
    Bottom Line
    Yes, I would recommend this to a friend.
