    Great product
    By  DIRK,  a  Verified Buyer  from  Texas  on  January 02, 2022
    Most the time I carry one bottle in my car when I'm on road trips. I like to put it in on the last tank of gas before I get home. Not sure if it does anything but my car does seem to run alittle smoother. Normally I just run ethanol free gas and never use fuel additives.
    Bottom Line
    Yes, I would recommend this to a friend.

    Added Insurance
    By  WAYNE,  a  Verified Buyer  from  Chatfield, MN  on  December 28, 2021
    I add Amsoil P.I. Performance Improver Gasoline Additive to all my vehicles every 3 - 4 months. Since I have done this I have had absolutely no problems with injectors and valves. I have to assume it is working, but in any case it provides me a sense of reassurance that I'm doing some preemptive maintenance. Thank you Amsoil for providing top notch products!
    Bottom Line
    Yes, I would recommend this to a friend.
