    I have been using this for years.
    By  CONSTANTINE,  a  Verified Buyer  from  East coast   on  October 20, 2026
    I have been using this PI fuel treatment in all my gasoline engines. From lawnmowers to cars and trucks. It keeps them running smooth. My lawnmower was hard to start, and ran rough. I added this. Ran a tank of gas through it while mowing and changed the spark plug afterwards. Runs like a dream now. It sat for months. Started on 2nd pull
    Bottom Line
    Yes, I would recommend this to a friend.

    Very good product
    By  EARL,  a  Verified Buyer  from  Macungie, PA  on  September 29, 2026
    I put this treatment in my cars tank about 5 or 6 times a year. The engine runs really well and gas mileage has improved over time. The only small problem to me is the plastic seal under the cap. It can be tough to remove.
    Bottom Line
    Yes, I would recommend this to a friend.

    Strong cleaner
    By  WILLIAM,  a  Verified Buyer  from  AZ  on  September 22, 2026
    I have a 2022 BMW with 20,000 miles. I've been noticing the engine has a little stumble now and then at idle at a stop light. I put a whole bottle of this injector cleaner in with a full tank of gas. By the time I'd used a half of a tank of gas the engine idles so smooth that I can't even tell if it's running or not. I look at the tachometer and it's idling very nicely and smooth. This stuff works !!
    Bottom Line
    Yes, I would recommend this to a friend.
