I don't have the time to use the boat as often as I would like. I know fuel gets stale when it sits there. I add fresh fuel once in a while, and also add the StaBil to the gas. It must be doing a good job because I never have any issues when I go to run the boat. With a charged battery I'm ready to go. I always keep a supply of this fuel treatment in the garage.

Love it for stabilizing marine fuel. However I spilled some on the fiberglass And it made a horrible stain. After searching on the Internet it seems that lots of people have problems with stained fiberglass and stained vinyl. Why can't Goldeneagle remove the dye or Change it? I'm switching to startron

    • Great for early signs of fuel issues

    Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

    I was starting to have low speed idle issues after adding one bottle of this product to about 40 gallons of gas within two to three hours of running time low speed idle issues cleared up.
    I'm using this for an outboard engine which tends to have low speed idle problems after using a lot of regular fuel when non ethonal is unavailable.

    Great for ATV

    By GearHead1986

    from Maine, United States

    Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

    Bought myself a new fuel injected utility ATV and wanted to add a fuel stabilizer to keep the fuel fresh between uses. After reading all the positive reviews and being a longtime 'stabil storage treatment' user I went ahead and started adding the 360 performance every fill up. No issues at all and peace of mind that the ethanol blend gas is not going to be hurting my new quad.

    Better Small Engin Performance

    By Chuck L

    from Chicago, IL, United States

    Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

    I have used this for several weeks now in my lawn mower, gas blower and gas trimmer, and found it helps it start on the first pull. 2 cycle engines seem to blow less oil smoke. I live in Chicago so I will not have to worry about the gas storage over winter with this added. Great product will continue to use for all my small engines.

      Was having problems with my recently purchased 2012 Mercury 60 hp bigfoot with rough idle and bogging down at full throttle. Found recommendations online about this product and used accordingly. Worked great. Use it regularly now.

      Relialble product

      By Mark 1

      from Houston, TX, United States

      Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

      I have used Sta-bil 360 not only in my boat but also in my back up generator, pressure washer, chain saw and other equipment that sits for an extended period of time. I have never had any issues with my gas even after a period of 6+ months. This product is very reliable and will save you money from costly repairs due to stale bad gas.

      Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

      Living in South Florida has its advantages, but the summers can be brutal. Car shows and cruise nights virtually stop for most of June, July and August, which means the cars sit. I usually can smell the gas when I start the car after a month or so, as it doesn't take long to get the stale smell...except not today! I added Sta-Bil 360 to my tank aa little over 30 days ago and no smell!! And the motor started immediately and ran perfect. I recommend this product and will continue to use it.
