4700 Hy-per Fuel Complete Fuel System Cleaner, 16.9 oz.

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 Gasoline Fuel System Treatment 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.
