    Another additive
    I don't know how to tell if this makes a difference or not but it's definitely not worse and I sure do love my bike so I figured it was worth perking up the gasoline a little

    The Best
    I use this to boost my octane so I can run pump gas with my high compression head. The instructions are clearly marked and performance is dead on.

    I have had good luck with this in the past. Could be in my head but I think it may increase power somewhat noticeably on my 2015 YZ250f. My buddies and I dumped some in my brother's 2014 KTM 250SX-f and before a trail ride a while back - asked him if it felt different and he said it seemed to be running strong that day "for some reason." Think it may work!

    Great fuel additive!
    1 ounce per gallon, and it improves throttle response like none other!

    can i use Sta-bil Fuel stabilizer Storage with this?
    Diego Z on Nov 7, 2017
    BEST ANSWER: That's what I do if my fuel is going to sit around more than a month. I use Hi-Test for my KTM 250xcw smoker to boost octane from 91 up to about 95.

    I also sometimes use Bey-Ray All in one for the 500exc dual sport. However, All in One is very concentrated with 4 oz all that's needed to treat 40 gallons = 1/2 oz (15 ml) for 5 gallons. So you need an accurate graduated cylinder to measure no larger than 100 ml capacity.
    How many ounces of this would I put into a 5 gallon gas tank?
    Anthony M on Jul 20, 2017
    BEST ANSWER: I typically do half a bottle (8oz) per 5 gallons of 91 octane gas for my '06 YZ250f and 450f. People generally think of octane boosters as snake oil, especially since 1 'point' is 0.1 octane. So 1 ounce of this will only raise the octane of 1 gallon of gas 0.2-0.4. I believe I can feel a difference in throttle response but it's probably all in my head. At the very least Hi-Test seems to keep the gas from going bad and the carbs from gumming up.
    Can I use hi test with aviation fuel, particularly AVGAS 100LL?
    Walker R on Nov 14, 2017
    BEST ANSWER: I don't really know if there is any contraindication for using HiTest with AVGAS 100LL. It is already 100 octane. Do you need to increase the ocatane more? In using the HITest to increase octane rating of 91 octane unleaded pump gas in California it provided some improvement (less detonation in higher compression engine) but I only used one bottle. I obtained better detonation reduction when I used Race Gas Race Fuel Concentrate.
