    Not much different
    By  MICHAEL,  a  Verified Buyer  from  California   on  December 25, 2020
    Most Amsoil products do a job that you can usually feel but PI was disappointing. It cost more than many similar fuel cleaners but you won’t notice any difference. Perhaps lab results show something different but in real world road condition you can save money & get the same results.
    Bottom Line
    No, I would not recommend this to a friend.

    Improved?
    By  S. Kovax,  a  Verified Buyer  from  Texas  on  December 25, 2020
    Another product that is quite hard to measure as a consumer. I used one bottle in a 36 gallon tank so who knows what happened. It's possible I might need two bottles for such a large tank to have any measurable results.

    Best cleaner on TGDI Ford Ranger 2020
    By  PATRICK,  a  Verified Buyer  from  Ca  on  December 06, 2020
    Tried other products including Redline . Noticed very little difference with the Redline product and vehicle started idling a bit erratic at 23000 or so. Put in PI and after about 100 miles all erratic issues resolved . Great product . Buying more
