Fact is FPPF KNOWS and treats fuel.

As industry leaders in fuel treatments and additives, FPPF has seen it all. Here are the answers to some of the most frequently asked questions we receive and the FPPF products that solve your fuel problems.

Will the product measurably affect the cetane number of fuel? (Reduced cetane may cause starting difficulties, especially in cold weather, and can cause knocking and rough engine operation from ignition delay.)

FPPF provides many products with cetane improvers. Our 8+ Cetane product is the most potent product on the market today. Our Total Power, Lubricity Plus Fuel Power, Agri-Fuel, Liquid Muscle, Auto Truck and custom formulas all contain cetane improvers. The use of all other FPPF products maintain cetane levels and do not reduce cetane ratings as is the case with other additives.

What are the risks involved with ash in fuels? And do FPPF products increase the ash content of fuel?

High ash levels in the fuel can cause higher rates of ring and piston groove wear that may need to be evaluated by fleets using high ash fuels. High ash content can also increase the level of particulate emissions from diesel engines and may need to be evaluated to determine the impact, if any, on emissions requirements that the equipment user is required to meet. High-ash fuel may also reduce the number of miles/hours between service intervals on certain types of after treatment. On other types of after treatment, high ash fuels might reduce the life of after-treatment components. Thus, before an additive is used, the impact on after treatment devices should be evaluated.

FPPF fuel additives do not contribute to increased ash content in fuel. Since several of our products actually enhance the combustion efficiencies of the fuel they could potentially reduce the fuel ash content.

Do FPPF products contain any metallic compounds or any other elements other than hydrogen, carbon, nitrogen, or oxygen? Also, is the product EPA registered?

All gasoline and diesel motor vehicle fuel additives are required to be registered in accordance with the regulations at 40 CFR 79. Lists of registered gasoline and diesel additives are available at http://www.epa.gov/otaq/fuels/index.htm. Some metallic trace elements can be beneficial as combustion catalysts and/or smoke suppressors in low concentration of just a few parts per million when blended in the fuel; any greater concentration will measurably increase total ash content as per above. Some metals can destabilize fuel in storage, from particularly abrasive ash, or produce very toxic exhaust emissions; it is recommended that independent specialist advice be sought before using any additive package containing metallic compounds. Halogenated compounds (e.g. containing chlorine, fluorine and/or bromine) and sulfur compounds form highly corrosive acids at the combustion stage. These acids, when introduced into the crankcase through downward blow-by, rapidly delete the lubricating oil additive package to form sludge in addition to their corrosive effect on all metallic engine components.

FPPF diesel fuel and heating oil additives contain no heavy metals or metallic compounds that could potentially be harmful to engines or burners. The FPPF gasoline additive products Ethanol Gas Treatment and Marine Ethanol Gas both contain a permitted amount of the only approved non-alcohol based octane booster in the United States: MMT. MMT does contain some manganese, but the levels are well below permitted levels for both engine and environmental criteria.

Will the product measurably increase the vapor pressure and/or reduce the flash point of the fuel? (If yes, this may cause an explosive safety hazard and may also be illegal.)

None of our fuel additives reduce the flash point or increase the vapor pressure of the fuel significantly. Almost all FPPF products contain high flash active ingredients and carrier solvents that do not vary significantly from pure #2 diesel fuel or heating oil. The only product that has some lower flash components is FPPF Melt Down. This is not a problem since, when used as directed, it will not change the overall fuel vapor pressure or flash point significantly. One interesting point, FPPF’s Melt Down actually modifies the flash and vapor pressures of the fuel significantly less than competing de-gelling products on the market today. When originally formulating Melt Down, FPPF Chemists utilized only active ingredients to minimize any potential negative effects to the fuel and engine components yet provide excellent performance.

Will the product significantly change the viscosity of the fuel?

Viscosity is unaffected by the use of all FPPF fuel additives. Remember the treat ratio of most FPPF additives is 1:1000 or greater. Our hydrocarbon-based fuel additives have viscosities very close to #2 Diesel Fuel and heating oil.

It’s important to note that increased viscosity may lead to incomplete combustion. Reduced viscosity may accelerate fuel pump and injector wear rates from lowering of the inherent lubricity of the fuel.

Will the product complex with sediment or water, either suspended in the fuel or settled in fuel tanks, to form sludge suspensions capable of plugging fuel filters and/or injectors?

All FPPF additives help to eliminate both water, sediment or sludge in fuel. Further, one of the primary benefits of FPPF products is their ability to chemically breakdown complex oil-based polymers formed in the fuel aging process. This slows down the oxidation of the fuel.

Do FPPF products contain sufficient corrosion inhibitor?

As fuels are more severely hydro-treated, they tend to become more corrosive. Fuels have less corrosion protection as they move downstream through pipelines. The use of a corrosion inhibitor should be considered if issues have been identified.

Some corrosion inhibitors are put in diesel fuel at the refinery. FPPF Fuel Power acts as a corrosion inhibitor. Since it is included in the formulation of several other FPPF products, such as Fuel Power, Polar Power, Total Power, Lubricity Plus Fuel Power and HOT 4 in 1, they have the added benefit of reducing potential corrosion. FPPF Super Fuel Stabilizer, custom formulas, Fleet Formula and Total Power all contain added corrosion inhibiting chemistry.

Do FPPF products affect the verification of any device, retrofit or original equipment, by any governmental regulatory body?

FPPF have no effect on verification equipment.

Do FPPF products clearly state the correct amount of treatment needed per gallon on the label?

Yes. All FPPF product labels clearly note the recommended treat ratio and all options for enhanced fuel treatment.

Will the product remain indefinitely blended in the fuel, or will it settle out during fuel storage?

All FPPF fuel additives remain in complete solution with the fuel and do not separate over time.

Do FPPF products contain gasoline or other solvent hydrocarbons that may cause detrimental side effects on equipment and may be potential safety hazards?

There are no gasoline or potentially harmful components in any FPPF diesel fuel and heating oil additives.

Will the product change the cold weather performance characteristics of the fuel? (i.e., cloud point, LTFT, CFPP, and/or pour point)

FPPF winter additives are second to none for reducing the LTFT, CFPP and the Pour Point of diesel fuel and heating oil. FPPF Polar Power, Total Power, Biodiesel Winter, Fleet Formula Winter, Auto Truck Formula and HOT 4 in 1 additives all contain strong anti-gel active components that significantly reduce the temperature at which diesel fuel and heating oil will thicken and eventually solidify.

Aftermarket additives in low dose concentrations typically do not measurably reduce the cloud point of the fuel. Cloud point additives are typically added at the refinery and not as aftermarket products. Aftermarket additives may not affect each of the remaining properties. See TMC RP 356, Cold Flow Operability of Diesel Fuel.


Does the additive have any sensitivity to over-treat? If so, what are the consequences?

Over-treating is not a problem with FPPF additives. Generally the flash point and the viscosities of FPPF products are very similar to diesel fuel and heating oil. The combustibility of each product is also similar. Even if 10 times or more the recommended treatment quantities were used no ill effects would manifest.

Do FPPF products clearly state that they meet all federal and state regulations for ultra low-sulfur diesel (ULSD)?

Yes, all FPPF additives meet the required 15 PPM maximum. Sulfur content of ULSD is limited to less than 15 ppm by law for use in diesel motor vehicles. Improper use of an additive with greater than 15 ppm sulfur content may result in a non-complying diesel fuel.

The only exception is FPPF Killem. Killem is an EPA-registered fuel biocide that can be used in all hydrocarbon-based fuels including diesel fuel, heating oil, gasoline, bunker fuels and more. The treat ratios are extremely low and are specified on all containers as required. The PPM of sulfur in Killem is greater than 15. Conversely, due to its extremely low treat ratio requirement, Killem will only augment fuel sulfur content less than one PPM.  If you have any questions regarding this product, please contact us.

Do FPPF products contain lubricity additives? If so, are they compatible with the fuel oil and do FPPF additives measurably improve the HFRR lubricity performance of the fuel?

Several of the FPPF fuel additives contain lubricity improvers. Lubricity Plus Fuel Power, Fuel Power, Lubricity 100%, Total Power, Polar Power, Agri-Fuel and Liquid Muscle all contain varying amounts of lubricity additive. FPPF primarily uses a complex synthetic lubricity enhancer that provides the most effective lubricity enhancement with a minimal chance of filter plugging or sludge formation.

Do FPPF additives contain antioxidants and stability additives?

FPPF fuel additives contain stabilizers that keep fuel fresh over time. These help stabilize the fuel, prevent fuel degradation and prevent peroxide build up in ULSD and biodiesel. ULSD is relatively stable, but peroxide formation may occur and cause embrittlement of elastomers and rubber seals. Additives that contain antioxidants can prevent peroxide buildup.

One of the most important features of a sound fuel stabilizing package is the inclusion of powerful anti-oxidation chemistry. The premier stabilizer FPPF product is Super Fuel Stabilizer, which contains a metal deactivator, oxygen and thermal breakdown blockers, and chemical coupling agents. Other FPPF products with stability enhancers include Fuel Power, Total Power, Lubricity Plus Fuel Power, Agri-Fuel Treatment, Marine Diesel and Liquid Muscle.

Are FPPF additives compatible with biodiesel blends of fuel? For what percentage of biodiesel (B2, B5 or greater) is the product rated?

All FPPF products can be used effectively with biodiesel and biodiesel/diesel fuel blends. FPPF has two products specifically formulated to improve biodiesel fuels: FPPF Biodiesel Fuel Power and Biodiesel Winter Formula. Both products contain biodiesel stabilizers and the winter product contains biodiesel anti-gel. These products also provide all the benefits of our non-biodiesel specific products.

Do FPPF additives affect warranty? Does the amount of water @200 ppm affect warranty?

FPPF products do not violate engine warranties. They only improve your fuel.

But it’s always important to check with the engine manufacturer for water contamination allowances.

Do FPPF additives emulsify or demulsify?

This question is product specific. FPPF products containing Fuel Power encapsulate water, but technically are not true emulsifiers.

Fuel Power and all products containing Fuel Power work effectively with all engines and are compatible with the latest technologies including DPF and Reger Technology. They actually enhance the operation of both. FPPF has products that could be classified as de-emulsifiers. This list includes Liquid Muscle, Diesel Injector Cleaner, 8+ Cetane and Lubricity 100%.
