The Most Complete Formula Available: Rislone Hy-per Fuel Gasoline Fuel System Treatment

Over time, poor or questionable gasoline can foul up your car’s fuel system. It’s important to keep this critical system clean so your car can work at peak efficiency and power. Rislone Hy-per Fuel Gasoline Fuel System Treatment (p/n 4700) is made to improve the quality of gas by increasing its cleaning ability, adding lubrication, removing contaminants, reducing spark knock, and helping to prevent the fuel from going bad. It’s far more than your average fuel injector cleaner — it’s one of the most awarded and popular fuel system treatments on the market. It’s even won a PTEN (Professional Tool & Equipment News) Innovation Award – a difficult task for a fuel treatment product.

One dual-cavity bottle contains the same amount of additives equal to a bottle of regular fuel injector cleaner, upper cylinder lubricant, fuel stabilizer, gas dryer, gas treatment and octane booster. In other words, this is one powerful bottle. This formula increases power, performance, mileage and saves you gas by cleaning and lubricating the complete fuel system. It also happens to be our most popular fuel treatment worldwide.

“WRX Limited owner and this stuff is amazing. It brings mid-grade unleaded up to snuff and gives a healthy boost to my cars performance when adding it to a tank-full of Premium. One bottle and I am already experiencing better response in throttle performance and smoothness in acceleration. I’m done using Redline – this stuff blows its doors off and is much more economical.”

“Great stuff for 4 cycle marine outboard. I made the mistake of ending the boating season with only 1/4 tank of gas. The tank sat over the winter with condensation creating water in the fuel system. Didn’t realize the problem till we started the engine the next season and tried to accelerate. Spit & sputter city. Ugh. Read recommendations about the Resilone Fuel Treatment System and gave it a try. Took a few minutes and revs to get it going, but in a matter of minutes, the engine was back to normal. Fuel issues neutralized. I use this product every season opening now as a matter of routine. Great stuff. Highly recommended.”

“This stuff really works!  I rarely put anything in my car’s fuel tank except for fluids designed designed to combat the effects of ethanol (the biggest boondoggle ever foisted on a sleeping public), but this stuff really works. I noticed the difference within 10 minutes.”
