  • How does Rislone Fuel Injector Cleaner work?

    This product contains a unique blend of additives that clean & lubricate the entire fuel system, including the fuel pump, tank, lines, injectors, and even carburetors on older vehicles.

  • How can this reduce a noisy fuel system?

    The UCL (Upper Cylinder Lubricant) additive lubricates the fuel pump, injectors and upper cylinder to reduce friction & wear, reducing noise.

  • How much will my fuel mileage improve?

    This varies depending on the age of the vehicle, the quality of the fuel used, and how dirty the system is. It is normal for larger increases in MPG on the first dosage and then it will usually taper off and flatten out from the second dosage on. For best results use with every tank of fuel.

  • Will this work with Diesel Fuel?

    Yes, Rislone Fuel Injector Cleaner is designed to work with all diesel engines including ULSD Ultra Low Sulfur Diesel and Bio Diesel Fuel.

  • 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 4701 / 6 ounce bottle – Pour entire bottle into fuel tank. One bottle is concentrated to treat up to 20 gallons of gasoline or diesel fuel. 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. NOTE: For vehicles with known fuel lubrication problems, double the dosage.

  • Can I use in E-85 ethanol in my flex-fuel vehicle?

    Yes, Rislone Fuel Injector Cleaner with Conditioner & Treatment works with the E-85 and will lubricate the fuel system reducing the negative effects that ethanol has on the system.

  • What does EZ Nozzle tm 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 fuel tanks, including capless (no fuel 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.

  • Can I use in my turbo charged or direct injected engine?

    Yes, this is safe to use and works in all domestic and import turbo charged and directed injected gasoline (GDI) and diesel engines like the Ford EcoBoost (gas) PowerStroke (diesel) and GM Ecotec (gas) Duramax (diesel), Dodge Cummins Ram (diesel) and all others.

  • 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.

  • Can this replace the lubricant in the ULSD Ultra Low Sulfur Diesel Fuel?

    Yes, Rislone Fuel Injector Cleaner with UCL is an excellent lubricant and will replace the lost additives in the new reformulated diesel fuel.

  • Does it work with both fuel injected and carbureted engines?

    Yes, this multi-vehicle formula works with all fuel injected, direct injected and carbureted engines.

You can use this product with all gasoline, ULSD diesel and E85 Flex-Fuel engines, as well as all unleaded, oxygenated, reformulated and biofuels.

Easily Keep Your Fuel Injectors Clean

Keeping your car’s fuel injectors clean is critical for maximum performance and the best fuel economy possible. Clean fuel injectors also mean your high-pressure fuel pump and system doesn’t need to work as hard, increasing longevity. If your car hasn’t had a fuel injector cleaning in a while, or if you’re starting to have problems with performance, sluggishness, throttle response or fuel efficiency, consider our 6 oz. Rislone Super Concentrated Fuel Injector Cleaner.

Designed with a special bottle for easy installation and no spilling, it only takes a moment to add our product to your fuel tank. In a very short time, most of our customers see a difference, with a boost in power and less lag. Most vehicles find a more stable idle as well, as well as reduced engine noise. Our scientifically advanced fuel injector cleaner is designed to get the most out of your engine and provide the smoothest fuel delivery possible.

Fuel systems and fuel injectors can get dirty for several reasons:

  • Contaminated fuel: While most gas stations provide clean fuel, it’s possible to get a bad batch of fuel or a dirty tank, pump or nozzle. It doesn’t take much dirt to disrupt your fuel injectors, due to the small size of these holes, so even a small amount of dirt can cause a noticeable performance and efficiency problem under your hood.
  • Varying gasoline quality: Between various gasoline brands and seasonal fuel blends, the fuel your car gets can be inconsistent. With continued use of our super concentrated fuel injector cleaner, you can reduce carbon build-up which causes pre-ignition, power loss, burned valves and broken rings. Our technology also cleans injectors to reduce loss of fuel economy, hesitation, pinging (spark knock), and helps restore performance.
  • A clogged or malfunctioning fuel filter: Modern vehicles come with a fuel filter to remove most contaminants. In some cases, when your fuel filter gets clogged or damaged, particles can make it past and into your injectors. Make sure you replace your fuel filter according to the manufacturer’s recommendations.

In the end, it doesn’t matter how your fuel injectors and fuel system got dirty. What you want to know is how to clean it. With Rislone, it usually only takes one dose of our 6 oz. Fuel Injector Cleaner. This advanced product is designed to clean your injectors from the moment you pour the product into your tank, and it keeps cleaning as you drive.
