    Eat high gas prices!
    By  BILLY,  a  Verified Buyer  from  Va  on  April 03, 2021

    Describe the issue

    Not only does this product Lubricant you upper cylinders, it also increases fuel mileage! My mileage in my 2018 RAM 1500 w/5.7 jumped an average of .5-.8 mpg when using this product! And if it lubricants well enough to increase mileage think about the added longevity it’s adding to you engine as well! Great job Amsoil!
    Bottom Line
    Yes, I would recommend this to a friend.
