FAQ
  • What does Rislone Diesel Fuel System Treatment do?

    Rislone Diesel Fuel System Treatment improves the quality of diesel fuel by increasing its cleaning ability, adding lubrication, removing contaminants, fighting corrosion, and helping to prevent the fuel from gelling & going bad. Simply put, it is the best all in one diesel fuel additive money can buy.

  • How does Rislone Diesel Fuel System Treatment work?

    It literally contains a combination of almost every type of diesel fuel additive on the market including ULSD sulfur substitute, injector & complete fuel system cleaner, UCL pump & injector lubricant, anti-gel cold flow improver, fuel stabilizer & conditioner and Cetane booster & diesel treatment.

  • 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 every 5,000 miles or with every oil change.

  • Will this work with all types of Diesel Fuel?

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

  • Will this harm the catalytic converter or diesel particulate filters?

    No, this will not harm your engine or any emissions components including catalytic converters, particulate filters, EGR valve or DEF systems.

  • How much do I use?

    P/N 4740 / 16.9 ounce bottle – Pour entire bottle into fuel tank. One bottle is concentrated to treat up to 35 gallons of diesel fuel. For larger vehicles use one bottle per 30 gallons of fuel capacity.

  • How many points will it boost the Cetane level?

    Typical numbers show a 1 to 2 point increase in Cetane level.

  • How low will it improve Cold Filter Plugging Point (CFPP)?

    Typical results show up to 13°C (23°F) reduction in the Cold Filter Plugging Point (CFPP).

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

    Yes, Rislone Diesel Fuel System Treatment is an excellent lubricant and will replace the lost additives in the new reformulated diesel fuel.

  • What does EZ Nozzletm Spout mean?

    The EZ Nozzle is the name for the patent pending spout attached to the bottle. This allows the product to be safely and easily poured into all fuel tanks, including diesels with misfueling device systems. Because it is designed like a regular diesel fuel nozzle you would see at your fuel station, it allows the product to work in all vehicles.

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

    Yes, this is safe to use and works in all domestic & import, car & truck regular, intercooled, turbo charged and directed injected diesel engines like the Ford PowerStroke, GM Duramax, Dodge Ram Cummins and all others.

  • What is a misfueling device?

    Some diesel vehicles have a special fuel tank receptacle that only allows a fuel station nozzle the specific size for diesel to be installed in the vehicle. This prevents accidentally adding gasoline to the vehicle. But this also makes it much more difficult to use additives in those vehicles. The Rislone Diesel Fuel System Treatment bottle contains a special spout which allows it to work in these vehicles.

Overview

Not the First, but the Best: Rislone Diesel Fuel System Treatment

Modern fuel systems, even with today’s fuel chemistry, need some help to remain at peak performance. Diesel engines are no exception. Our Rislone Complete Diesel Fuel System Treatment improves the quality of diesel fuel by increasing its cleaning ability, boosting cetane, adding lubrication, removing contaminants, fighting corrosion, and helping to prevent the fuel from gelling and going bad.

This one dual-cavity bottle contains the same number of additives equal to a bottle of regular fuel injector cleaner, upper cylinder lubricant, fuel stabilizer, anti-gel, diesel treatment and cetane booster. Talk about the perfect all-in-one! It also increases power, performance and mileage and saves fuel by cleaning and lubricating the entire fuel system.

Discover the Best Diesel Fuel Treatment

There’s been a lot of talk in the news lately about diesel fuel. Long known for their low-end power and longevity, diesel engines also have a reputation as a “dirty” engine, due to the increased particulate emissions. While that’s not true, diesel engines are different than gasoline engines, and requirements to keep a diesel running in top shape are more specialized than you might think.

Specifically formulated for modern diesel engines, our diesel fuel cleaner works quickly to treat your diesel engine and to allow for the best possible diesel driving experience. Clean diesel emissions are not only good for the environment, but they also help keep the tailpipe and rear bumper of your car from turning black from diesel soot and particulate. This product works in multiple ways:

  • Loosens dirt: Diesel fuel can often have contaminants. Dirt and debris can quickly plug high-pressure diesel fuel ramps and injectors. Even a single blocked injector can make your engine run rough and lower its fuel economy.
  • Cleans the system: Once the dirt has been removed from your injectors, it has to be removed from your fuel system. Our advanced scientific formulation breaks down contaminants and allows them to be burnt off with your engine’s combustion.
  • Keeps your system running like new: When you add our diesel fuel cleaner to a tank of diesel fuel, the additive continues to treat and protect your entire fuel system. This includes boosting cetane levels, providing anti-gel protection, cleaning diesel fuel injectors and stabilizing diesel fuel.

Once you’ve cleaned your diesel engine with our complete fuel system treatment, you’ll quickly see a difference. You’ll feel more power, better responsiveness and a more stable idle. If you watch your fuel economy over several tanks, you’ll also see an increase in fuel mileage and lower fuel costs. Add in the increased longevity of your injectors and high-pressure fuel system and you’re looking at real savings.

You get all of this with one simple product. We’ve spent nearly 100 years formulating and improving our automotive chemical solutions. This includes our high-performance diesel fuel system treatment. We’re an industry leader and offer the best diesel fuel treatment money can buy.
