    What Can I Say
    By  OZZIE,  a  Verified Buyer  from  West Palm Beach  on  July 24, 2023
    Not in tune enough with if this product is actually working or not, honestly can't say I notice a difference. Being that it is a Amsoil product I have put my trust in the product doing what it is suppose to do. Use it a few times between oil changes.
    Bottom Line
    Yes, I would recommend this to a friend.

    Cylinder lubricant
    By  JOHN,  a  Verified Buyer  from  NC  on  June 13, 2023
    It's always hard to tell the effects of an upper cylinder lubricant However, I like the fact that it provides a degree of lubrication for all the way from my fuel pump through the injectors and cylinders. If you trust that fact that all Amsoil products are excellent Trust that this on works just as well
    Bottom Line
    Yes, I would recommend this to a friend.

    Put this in my 2020 Honda CRV, mpg jumped from 32.4 to 34.9 in town driving. I wonder what the PI Fuel Additive will do. Engine operates quieter and lower rpm @ idle. Definitely using this in both my Hondas at fill up!
