    This stuff is good.
    By  Bob,  a  Verified Buyer  from  Plum Island Ma  on  May 31, 2023
    So you want your injectors cleaned? This product is worth every penny. The injectors in my Mercruiser 7.4l were gumming up and I was told they needed replacement. I put two bottles of this stuff in and ran it in the water under load for about 15 minutes and all of a sudden, the boat is running like new. No issues after 10 hours.
    Bottom Line
    Yes, I would recommend this to a friend.

    Noticed a difference
    By  NEIL,  a  Verified Buyer  from  Durham NC   on  May 27, 2023
    I have a T-GDI vehicle and after using this product, I am noticing better acceleration and idling, albeit a very subtle change. Anything that can help clean injectors is a very good product. I will continue to use this product every 4000 miles as instructed in the directions for use.
    Bottom Line
    Yes, I would recommend this to a friend.

    Good product
    By  PETE,  a  Verified Buyer  from  Virginia   on  May 09, 2023
    I try to use this product every other oil change and I'm amazed that every time it seems to get better MPG. I use it on a Suburban with a 5.3. When I started using the products from Amsoil it would average 14.5 MPG now it averages 15.9 MPG. Still not great but I'll take what I can get.
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent Product
    By  JAMES,  a  Verified Buyer  from  SE Texas  on  May 08, 2023
    Been using PI now for several years. In my wife's previous Ford Expedition (2007 5.4L) she did not buy the most quality fuel all the time. Would add PI at every oil change and could actually tell a difference. I use PI in all our current vehicles as well. Not sure I see the MPG increase that it states, but it does help performance.

    2016 GMC SIERRA 1500 5.3 vortec
    By  GIOVANNI,  a  Verified Buyer  from  Hanna  on  May 07, 2023
    Bought the truck used. Was operating on f as rm fuel. Was never winter driven and stored in a quonset. 60k Km on odometer. Seemed to be burning a bit rich. Thought I noticed a bit of soot. After one application of this product I noticed a significant improvement in average fuel economy and the soot issue cleaned right up. The engine idles smoothly and power and acceleration was improved. I ran one applications through a 2013 Buick Enclave. Same results. Smoothed out the idle and marked improvement in fuel economy. I’m happy with this product. W
