    WOW!
    By  Chief Worm,  a  Verified Buyer  from  Florida  on  January 18, 2018
    I used this on a company car that only drove short distances around the work site (Orlando Airport). I used this product on my personal car and liked the results so I used it in this company car and WOW!!! The results were phenomenal. No more rough starts. No acceleration lag. It was like a totally new car.

    Really works!
    By  Curt,  a  Verified Buyer  from  Elizabethtown, PA  on  January 12, 2018
    I use this in all of my vehicles, but I really know it works when I had a motorcycle that was used very little. The carbs were gummed up and it wasn't running right. I really didn't want to tear the carbs apart, so I ran a few tankfuls of gas with PI in it through and it cleaned up the carbs. The motorcycle now runs right!
    Bottom Line
    Yes, I would recommend this to a friend.

    Can I drink this and operate better?
    By  Husbandly Car Repairer,  a  Verified Buyer  from  Seattle, WA  on  January 12, 2018
    Wifey left her flagship Mercedes Benz unused for a long time and the engine was really rough. I poured in 2 oz per tank until the idle was smooth. I recommend putting a little in at a time in case injectors get plugged with a whole bottle. So start slow for the first tank and then increase. Lovely stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    Just cheap insurance for fuel system
    By  Iceman139,  a  Verified Buyer  from  Pennsylvania  on  November 21, 2017
    I am not sure if the product actually does much to improve the fuel mileage of my 6 cylinder Chrysler 200 but it does seem to run smoothly . I just use it when I change my oil and filter to help keep the fuel injection system clean. I figure if I'm gonna put in clean oil.and filter, might as well clean fuel system too!
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil P.I. Best there is
    By  San Diego,  a  Verified Buyer  from  TN  on  November 04, 2017
    Used in a Scion tC, cleaning agents inside work very effectively. Can feel power being restored to the car over the course of the tank of gas. I use 3/4ths a bottle every 5000 miles to make sure everything is clean and pristine.

    By  Crimefighter,  a  Verified Buyer  from  Fort Worth, TX  on  October 31, 2017
    My Honda Accord, EX-L had a hesitation problem for some time. I tried other additives that did not work. When I tried Amsoil Gasoline Additive it worked and is still working. Next treatment is at 4000 mile after first use.

    Excellent results
    By  Champion200,  a  Verified Buyer  from  Waterloo, Iowa  on  October 28, 2017
    I use P.i. every 5000 miles because it's easier to track that frequency on my odometer. I have over 130,000 miles on my 2007 Silverado and have experienced zero fuel injector problems.
    Bottom Line
    Yes, I would recommend this to a friend.
