    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.
