Power Service Diesel Fuel Supplement +Cetane Boost

Winter Diesel Fuel Anti-Gel, Fuel-Filter Protection and Cetane Booster

Power Service Diesel Fuel Supplement +Cetane Boost is a winter diesel fuel additive designed to help prevent fuel gelling and protect fuel filters from plugging with ice and wax. Power Service recommends using this Arctic Formula during cold-weather operation when temperatures drop below 30°F.

The formula works by modifying the size and shape of wax crystals that form as diesel fuel gets colder, helping them remain small enough to pass through fuel filters. It also contains a de-icer that helps protect fuel filters and fuel lines from freezing caused by water in the fuel.

Diesel Fuel Supplement +Cetane Boost also boosts cetane to support faster cold starts and contains Power Service Slickdiesel Lubricator to help protect fuel pumps and injectors from increased wear associated with poor-lubricity Ultra Low Sulfur Diesel fuel. It is effective in diesel fuels including ULSD and biodiesel blends.

When Should You Use Power Service Diesel Fuel Supplement?

Use Diesel Fuel Supplement +Cetane Boost when ambient temperatures fall below 30°F and cold-weather diesel operability becomes a concern.

  • Below 30°F: Use Diesel Fuel Supplement +Cetane Boost, the white bottle, for winter operability.
  • Above 30°F: Use Diesel Kleen +Cetane Boost, the silver bottle, for injector cleaning and performance maintenance.
  • If the fuel has already gelled: Use Diesel 911, the red bottle, as directed to address the existing winter fuel problem.

Diesel Fuel Supplement is a preventive diesel anti-gel, while Diesel 911 is intended for a winter emergency after gelling or icing has already occurred.


How Diesel Anti-Gel Works

As diesel fuel cools, naturally occurring paraffin wax can form crystals. If those crystals become large enough, they can restrict or plug the fuel filter and prevent adequate fuel flow to the engine.

Power Service Diesel Fuel Supplement is formulated to modify the size and shape of these wax crystals so they remain smaller and can continue moving through the fuel system. It also helps prevent wax from settling to the bottom of the fuel tank during storage.


Fuel-Filter Icing Protection

Cold-weather diesel problems are not limited to wax. Water in diesel fuel can freeze on fuel-filter surfaces or inside fuel lines.

Diesel Fuel Supplement +Cetane Boost contains a de-icer designed to help prevent fuel-filter and fuel-line freezing caused by water.


Slickdiesel Lubricity Protection

Ultra Low Sulfur Diesel relies on adequate fuel lubricity to protect fuel-system components. Power Service's proprietary Slickdiesel Lubricator is designed to improve diesel fuel lubricity and help protect fuel injectors and pumps from increased wear.

Power Service states that treated fuel exceeds the ASTM D975 maximum 520-micron Wear Scar Diameter requirement and can achieve the 460-micron WSD level recommended by the Engine Manufacturers Association.


Power Service Diesel Fuel Supplement Treatment Amounts

Package Size Treats Up To
12 oz. 40 gallons

Power Service Diesel Fuel Supplement +Cetane Boost is effective in:

  • Conventional diesel fuel
  • Ultra Low Sulfur Diesel (ULSD)
  • Biodiesel blends

The product is formulated as a diesel fuel additive and should be added directly to the fuel tank. Do not add Diesel Fuel Supplement +Cetane Boost to the DEF tank.


Frequently Asked Questions

What does Power Service Diesel Fuel Supplement +Cetane Boost do?
It is a winter diesel anti-gel and fuel treatment designed to prevent fuel gelling, reduce wax-related fuel-filter plugging, protect against fuel-filter icing, boost cetane for cold starting, and provide additional lubricity for fuel pumps and injectors.

When should I use diesel anti-gel?
Power Service recommends Diesel Fuel Supplement +Cetane Boost when temperatures drop below 30°F. Treat the fuel before cold-weather problems occur.

Does Power Service Diesel Fuel Supplement prevent diesel fuel from gelling?
Yes. Preventing fuel gelling is one of the product's primary functions. The formula modifies wax crystals so they remain smaller and can continue passing through fuel filters.

Will Power Service Diesel Fuel Supplement fix already-gelled diesel fuel?
It is primarily a preventive product. If diesel fuel has already gelled or the vehicle will not start because of cold-weather fuel problems, Power Service recommends Diesel 911. After the problem is corrected, Diesel Fuel Supplement can be used for continued winter protection.

How much Power Service anti-gel should I use?
The amount depends on package size and operating conditions. At the standard treatment level, a 12 oz. bottle treats up to 40 gallons, a 26 oz. bottle up to 100 gallons, and a 64 oz. bottle up to 250 gallons. Larger concentrated packages treat substantially more fuel. Follow the container directions, particularly below 0°F or when treating biodiesel blends.

How much Power Service Diesel Fuel Supplement per gallon should I use?
The treatment rate varies by product concentration and temperature. Follow the specific container label rather than using one universal ounces-per-gallon ratio. Power Service also increases the treatment rate during more severe cold weather and with biodiesel blends.

Yes. Power Service states that the product boosts cetane to help provide faster cold starts.

Is Power Service Diesel Fuel Supplement safe for ULSD?

Can Power Service Diesel Fuel Supplement be used with biodiesel?
Yes. Power Service identifies the product as effective in biodiesel blends. Treatment requirements may increase when using biodiesel, so follow the current container directions.

Can I use Diesel Fuel Supplement and Diesel Kleen together?

Is Power Service Diesel Fuel Supplement endorsed by Cummins?

Should Power Service Diesel Fuel Supplement be added before or after fueling?

    Only thing is I liked the 80 fl. ounce container as opposed to the 64 fl. Oz. Container and you was out of stock of the one gallon size.
