Hy-per Fuel Octane Booster
- Real MMT Power Boost
- Restores Lost Horsepower
- Stops Engine Knocks & Pings

Real octane boost. Real MMT.
If you’re all about high performance, then you know your car relies on octane for top performance. Our Rislone Super Concentrated Octane Booster does just that.
Rislone Hy-per Fuel 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.
Part Number: 4747
Dosage: One bottle is concentrated to treat up to 20 gallons of gasoline. For small engines, use ¼ bottle for every 5 gallons. For larger vehicles, use 1 bottle per 18 gallons of fuel capacity, or 1 oz per 3 gallons.
Size: 6 FL. OZ. (177 mL)

If you have a story to tell, let us know.
“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.”
