Rislone Super Concentrated Octane Booster increases octane rating to stop engine hesitation and knock & ping, while also increasing power & performance. Street legal formula works equally well on classic muscle cars, newer smaller harder working engines, off road and racing applications. Increased octane allows the engine to run optimum spark timing which not only creates more power, but in many engines reduces emissions and increases fuel mileage. Item: 4747

  • What does Rislone Octane Booster do?

    Antiknock formulation stops engine knocks and pings caused by low quality fuel.

  • What is spark knock?

    Spark knock, also known as knock, detonation, knocking or pinging in gasoline engines is when the air/fuel mixture in the cylinder explodes separately from the main ignition caused by the spark plug. This usually creates a metallic “knock” sound as the two fronts collide with each other causing extreme pressure inside the cylinder and possible engine damage.

  • Does it work with both fuel injected and carbureted engines?

    Yes, this formulation works on all fuel injected, direct injected & carbureted street, racing, supercharged and turbo engines.

  • What are some signs if I am using fuel that has a lower octane rating than my car needs?

    The number one sign is spark knock. You may also have hesitation when accelerating and lower power levels.

  • Will this harm the oxygen sensors or plug the catalytic converter?

    No, this will not harm your engine or any emissions components including catalytic converters, oxygen sensors, or the EGR valve.

  • How much do I use?

    P/N 4747 / 6 ounce bottle – Pour entire bottle into fuel tank. One bottle is concentrated to treat up to 20 gallons of gasoline. For smaller engines use 1⁄4 bottle for every 5 gallons. For larger vehicles use 1 bottle per 18 gallons of fuel capacity, or 1 oz per 3 gallons.

  • What is MMT?

    MMT or Methylcyclopentadienyl Manganese Tricarbonyl is a gas additive supplement octane improver that provides antiknock protection to reduce engine noise and damage from spark knock. It provides increased octane rating of gas, reduced emissions, enhanced engine life and protects the engine from damage.

  • How much will this boost my octane level?

    Typical results will increase octane over 20 points or 2 rating numbers.

  • Can I use with any type of gasoline?

    Yes, Rislone Octane Booster works with unleaded gasoline, ethanol E10 E15 E85 flex fuels and racing fuel.

  • What does EZ Nozzletm mean?

    The EZ Nozzle is the name for the patent pending spout end of the bottle. This allows the product to be safely and easily poured into all gas tanks, including capless (no gas cap) systems. Because it is designed like a regular fuel nozzle you would see at your gas station, it allows the product to work in all vehicles.

  • What does a flow valve do?

    The flow valve is built into the EZ Nozzle neck of the bottle and delays the start of pouring to help prevent liquid from spilling and damaging the vehicle finish like other competitive brands.

  • What is a capless fuel system?

    Capless fuel systems go under a few names like Ford’s Easy Fuel System, but basically it is a vehicle with no regular gas cap. Capless systems are on many vehicles including Ford, Chrysler, Dodge, GM, Cadillac and more. The reason the car companies are moving to this system is to prevent fuel evaporation and emissions issues if the gas cap is left loose, not installed or is lost. Only Rislone fuel additives will work with all capless, obstructed and regular fuel systems in cars and light trucks.
