    Great Oil, no complementary promotional gift
    By  RALPH,  a  Verified Buyer  from  Canada  on  May 21, 2023
    Great oil but did not receive the complementary gas additives with my order. When I asked via email about the missing products I was told they do not correct their mistake and if I was insistent they would apply $4.00 credit to my next order but no instructions on how to do this task.
    Bottom Line
    Yes, I would recommend this to a friend.
