    $8.50
    8oz treat 20 gallons

    Stabilizes 2 or 4 cycle fuel

    PRI-G For Small Engines is our compact version of PRI-G. It is conveniently packaged for easy and effective application by users of small engines.

    PRI-G Small Engine Gas Stabilizer offers true professional grade protection against fuel degradation. 

    That’s because PRI-G contains PRI’s advanced thermal stability chemistry – the same used by commercial vessels and public utilities for maximum fuel protection. 

    This means your fuel will stay fresh during long lay-up periods. Fuel systems stay clean and ready to go for quick starts and maximum engine reliability. 

    Formulated specifically for small two and four stroke gasoline engines, PRI-G also prevents power-robbing carbon deposits. Your engine stays clean, running at maximum efficiency with optimum fuel economy. 

    PRI-G is your insurance against costly repairs and premature engine component failures. 

    Simply add one ounce of PRI-G for every 2.5 gallons of fuel or one-half ounce for every 4.7 liters of fuel at each and every fueling. 

    Best yet, unlike common “dispersant” type stabilizers, PRI-G has an indefinite shelf life when sealed and is fully guaranteed to stabilize any gasoline at any time. In fact, independent laboratory tests prove PRI-G is more effective than any gasoline stability additive available today. 

    PRI-G may be used at double strength to restore old, stale gasoline when mixed thoroughly with the fuel. PRI-G Small Engine Gas Stabilizer is available in 8 ounce, E-Z measure bottles, treating 20 gallons of gasoline. Shelf life of PRI-G is three years.

    For E-10 and All Gasoline Grades

    PRI-G is a super concentrated, complete fuel treatment that improves any type of gasoline, including the latest E-10 blends, enabling them to perform to maximum potential. PRI-G’s industrial strength, enhanced thermal stability chemistry reacts with fuel upon contact, and provides multiple benefits:

    • Engines perform better and last longer
    • Engine power increased and fuel economy realized
    • Fuel system and engine deposits prevented
    • Phase separation inhibited for E-10
    • Fuel stays fresh and ready to use
    • Degraded fuel is restored to freshness
    • Hesitation, knocking, and pinging reduced

    Improved Engine Performance

    PRI-G works chemically within gasoline to improve the combustion process. Improved combustion means improved engine performance. You will realize increased power from your engine. At the same time, you will enjoy greater fuel economy. PRI-G reduces the hesitation, knocking, and pinging that is common in gasoline engines. It is also extremely effective at cutting harmful emissions. Smog tests are no longer a challenge.

    Reduced Maintenance Costs

    PRI-G’s proprietary, refinery- grade chemistry is unsurpassed at preventing carbon deposits and fuel system fouling. Your engine will remain cleaner and last longer, which means maintenance costs are significantly reduced. Keep your car, boat, or RV in great shape for years to come!

    Keeps Fuel Fresh and Ready To Use

    It’s a fact: fuel ages quickly! No matter how soon you use the gasoline you buy, it will have aged in your fuel tank by the time you use it; for that reason, you can’t afford to be without PRI-G. PRI-G keeps gasoline fresh. In fact, by treating the fuel annually with PRI-G, you can keep it fresh in storage for years! You’ll be assured a fast start for your engine next season, or whenever you use it next. Those operating a generator on a periodic basis are especially benefited by PRI-G use – when it comes time to run that generator, it’s fuel will be fresh and ready to go! If your fuel has already aged, PRI-G can still help. Tests have shown where PRI-G can restore aged fuel to refinery-fresh conditions.

    Super Concentrated

    PRI-G is super concentrated, with a dose rate of 1:2,000. This means PRI-G is extremely cost effective to use. Get the most out of your gasoline for only pennies a gallon! PRI-G also has three-year shelf life.

    Safe To Use

    PRI-G’s enhanced thermal stability chemistry works within the fuel instead of altering it, which means the product is completely safe to use. Fuel specifications aren’t changed, so engine warranties are not voided! PRI-G is safe and effective in both four stroke and two stroke engines. Use PRI-G today to get the most out of your gasoline and your engine.Bottle Size Gasoline Treated 16 Ounces 256 gallons 32 Ounces 512 gallons 1 Gallon 2,000 gallons
