    Been using Amsoil Since 1977
    By  DANIEL,  a  Verified Buyer  from  hampton, VA  on  September 11, 2023
    The best oil on the market. Used nothing but Amsoil since 1977 in all my vehicles I have owned. Yes it is expensive but you get what you pay for these days. Since Amsoil was the first ture 100% synthetic motor oil I have used in many trucks to pull a boat with no engine problems in any of them. When I sold a truck the engine still ran like new. There are now many synthetic oils on the market... but will always use AMSOIL...!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    0w-20 High Milage Motor oil
    By  JOHN,  a  Verified Buyer  from  RI  on  September 01, 2023
    I've always been happy with Amsoil as a product, However I think your rewards program needs updating, as i mentioned in a previous email I was quite unhappy to learn that my rewards were going to expire if I didn't use them soon, basically forcing me to make a purchase, even though I was not in at that time of any Amsoil products, well I didn't make a purchase and I lost my points which to me is not a good way to treat your loyal customers. You Asked, Respectfully submitted , John Reynolds
    Bottom Line
    Yes, I would recommend this to a friend.
