  • 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.

Rislone Super Concentrated Octane Booster

If you’re all about high performance, then you know your car, like your body, can use an energy boost from time to time. Our Rislone Super Concentrated Octane Booster does just that.

Rislone Super Concentrated Octane Booster increases your fuel’s octane rating to stop engine hesitation, knock and ping, while also increasing power and performance. The formula works equally well on classic muscle cars, newer, smaller, harder-working engines, off-road and racing applications. The increased octane allows the engine to run optimum spark timing, which not only creates more power, but also, in many engines, reduces emissions and increases fuel mileage. It’s also the best insurance against bad gas you can find.

Discover Rislone for the Best Octane Booster on the Market

We’ve all heard the word “octane” as it pertains to automotive gasoline, but we don’t all know what it means. In simple terms, the octane value of a fuel relates to the amount of compression a fuel can handle before ignition. A higher-octane fuel will therefore compress more before ignition occurs, resulting in more power. Higher-octane fuels cost more because of this potential for more power and the cost to refine and produce it.

It makes sense, then, that a product that boosts the octane of your fuel will give you more power. That’s why our engineers have created our Super Concentrated Octane Booster. We want you to have a fast and easy way to boost the octane value of a tank of gas when you want added power. If you aren’t near a gas station that offers high-octane fuel, or you prefer to carefully control the amount and quality of your additive, our fuel octane booster is the perfect choice.

As with all our automotive chemicals, our gas octane booster is easy to use. The result is almost instantaneous. You get a noticeable boost, especially under hard acceleration. Many of our customers who race their cars on the track or drag strip always carry around a few bottles. Instead of having to wait until your tank is empty and search out a high-octane fuel pump, you can simply add a bottle to your tank anytime.

Proven. Innovative. Effective. These are the hallmarks of our Rislone automotive chemicals and additives and how we’ve been able to create the best octane booster we’ve tested on the market. To locate a nearby supplier, simply

  • “I have a 2018 F-150 with the 3.5 liter twin turbo Ecoboost. I have the engine tuned to produce around 465 horse power. The tune requires the use of 93 octane gas. I always put a bottle of this in when I put gas in the truck. I can tell a considerable difference in power and performance when I use this product. I highly recommend it to anyone else who is running a turbo engine, or anyone requiring 93+ octane in their vehicle. Well done Rislone.”
