    Winterizing my 2018 GP1800 & 2013 FX SHO

    Hello and thanks for looking or any help suggested!

    From my understanding my skis run on 93 Octane. Around me they sell unleaded 93 octane, I have heard alcohol free fuel is the way to go. I have not seen alcohol free 93, so my question is when winterizing it is there something special I can do other than putting some Stabil in my tanks to cut out any harsh affect alcohol can do on your lines

    Thanks for your input

    SVHO engines specify 91 octane, not 93, as the baseline/minimum. Should be right on the sticker next to the fuel filler, and in the owner's manual.

    SHO engine is the same?

    If you have access to 91 octane gasoline without ethanol, I suggest that would be the fuel to use.

    At this moment I have yet to see 91 octane at a marina by me, I have seen 90 octane. All of my gas stations near me have 93, 89, and 87. If this has to be the way I winterize it, are there any suggestions to help?

    Thanks

    Use a fuel stablizer that is known to actually work with ethanol blended gasoline. Not just marketed that way, as 'compatible'.

    Startron has one, IIRC.
    And another couple of other companies too, forget which :/

    One thing you can do is mix 90 (no ethanol) and 93 (with ethanol) in a proportion that works out to 91 or slightly higher. Half and half would equal 91.5 octane (check my math), or fairly close. That would cut the ethanol percentage in the fuel tank in half.

    I also use startron for stabilizer. It works very well with ethenol/non-ethenol.
    Try "truegas" app to find non-ethenol fuel near you. It will tell you where to find and octane levels as well.

    http://www.starbrite.com/item/star-t...ategory_id=585 This link look right? and I have been using Stabil? is that a product that doesn't live up to its hype? Good idea on that mixture as well, hopefully I catch a marina open still at this time. Dang on cold!!

    Can you buy non-ethanol gasoline (90) at roadside gas stations?

    I've used Startron, the same as your link, for the last 6 years. My skis, both no supercharger, sit for 7 months. Startron has worked well for me. Each ski starts up as if they have only sat a few days. There are others that swear by Stabil which is also a good product. Stabil just has a shelf life once the bottle is opened. Neither of these have more alcohol in them as some other brands do. The Pri-G also states no alcohol. It's seems a little more expensive per gallon of gas treated. I'd mix as K447 mentioned to get your octane and then treat. Don't forget to run the ski on the hose with the treated gas so it gets to the injectors.

    I have not yet to see it, I am going to download the TrueGas app.
