## Overview

Rislone 4747-12PK Super Concentrated Octane Booster is a 12-pack of 6 fl. oz. bottles designed to enhance engine efficiency and power by raising octane levels. Compatible with gasoline and ethanol blends (E10, E15), it features a user-friendly nozzle for all fuel tanks, including capless systems, and is safe for catalytic converters and oxygen sensors.

## Description

Rislone Hy-per Fuel 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.

Review: Must have for any motorcycle - I use this religiously in all my harleys to offset lower quality pump gas. Bottle size is perfect fit for my swingarm bag. Usually get 3 to 4 fill ups from a single bottle. Won't ride without it.
Review: Actually Works! - I decided to purchase for my 2025 Ford Ranger Raptor to determine if I could tell a difference in horse power performance, even though I added a performance calibration computer program along with a Process West enlarged air box, to include the 3.5" cross over pipes to allow the turbos to really breath. My comments of the product are not based on anyrecent Dyno testing. I added one bottle to each of the 5-full tanks of gasoline of Sunoco 94 octane fuel. I did this to give the computer to evaluate and "learn" the fuel mixture change. On the 5th full tank full, I added one bottle and hit the road and accelerator. Truly I was shocked that the product made a noticeable change I could feel from behind the wheel. Both from a full throttle start, highway throtle punch and residential road driving acceleration. Again, not a dyno test but if I can edge out a noticeable difference, that's all I was l99king for. Without any details, I must have surprised drivers in their modified vehicles in the performance of this mid-size pick-up when I pulled away in small level straight and drag racing situations that arose. Additional performance parts will be added in the very near future but at least the gasoline octane booster proved its point to me.
