    Stands alone
    By  ERIK,  a  Verified Buyer  from  Binghamton ny  on  November 19, 2023
    This is by far the best formulation of a gasoline stabilizer available anywhere. It definitely does what it’s supposed to and outperforms all others that I’ve tried. You truly can have piece of mind when using this. I use it in all of my landscaping equipment.
    Bottom Line
    Yes, I would recommend this to a friend.

    My hardly used vehicle
    By  PAUL,  a  Verified Buyer  on  November 03, 2023
    I use this in all of my engines so they are not rusting from the inside out. I mostly like this product because I have a car that I put only a couple of thousand miles per year on and I don't want the gas to go bad or develop a rusty gas tank caused by water separation in the fuel.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  Rich,  a  Verified Buyer  from  Virginia Beach  on  April 13, 2023
    I use this in my cars that I don't drive that much because I'm no retired. Recently my wife took our main vehicle out of town and I had to use my Van that has been sitting for several months. The van started right up and ran great just like when it is filled with fresh gas.
    Bottom Line
    Yes, I would recommend this to a friend.
