    Performance I prover
    By  RICH,  a  Verified Buyer  on  December 01, 2023
    I can not positively say that this has improved my octane rating, however the studies have shown that it will. I do believe it will not harm your engine, it could only improve the quality of fuel you use. I just can’t say if it “improved” my gasoline consumption. I do believe the detergents would help keep fuel cleaner.
    Bottom Line
    Yes, I would recommend this to a friend.

    It Works
    By  BRIAN,  a  Verified Buyer  from  Charlotte   on  November 27, 2023
    Hello, recently purchased some Amsoil PI performance improver and I'm very happy with the results of this product. I feel that it did a very good job in cleaning the fuel system and taking out any contaminants that were remaining in there. I noticed acceleration was better overall and very smooth shifting. I like how it is engineered to be used every 4,000 miles so it's not something you need to worry about putting in your tank every time you fill up. I would not hesitate to purchase this product again I feel it's a good buy and a good value.
    Bottom Line
    Yes, I would recommend this to a friend.
