TMC –Technology Maintenance Council /American Trucking Association Recommendations


Peter M Guerra – VP Technology


1)  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 our custom formulas all contain cetane improvers. Further the use of all our other products maintain cetane levels and will not reduce cetane ratings as some other additives can.



2) Will product measurably increase the ash content of the fuel? If yes, what is the ash increase in parts per million in the fuel when the additive is blended at the maximum of 0.01 percent ash by weight which may approximate to 100 ppm. 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 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.?

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

Diesel Engine SCR and DPF Regen Systems When Used With Diesel Fuel Additives

Peter M Guerra – VP Technology



It has been brought to my attention that there are increasing concerns about the operation of Diesel Engines with SCR & DPF systems when used with quality fuel additives. There are some fuel additives that claim to improve the efficiency of both the DPF and the SCR systems on new trucks, let’s investigate this further.

First, let me briefly define each of these 2 systems:

• DPF (Diesel Particulate Filter) is the technology that incorporates the high tech filtering/regen processes to remove most solid carbon based emissions from fuel exhaust (the regen process is a costly self-cleaning of the system requiring downtime).  There are several different filtering methods, and a variety of filtering media employed, but the intended result is constant: less emissions. The actual results vary from 35% effective to over 99% success.

Technical Bulletin:Update Water Elimination in Diesel Fuel

Technical Bulletin: Update Water Elimination in Diesel Fuel

Peter M Guerra – VP Technology


Lately there has been an exceptional amount of discussion about the best way to eliminate water from diesel fuel bulk and vehicle tanks. Since fuel injection technology is changing, there are concerns about some of the more traditional ways of handling water in fuel systems.

Recently some vehicle manufacturers have even released bulletins discouraging the use of fuel additives that emulsify water in fuel. I wanted to clearify this matter and assure you and your customers, FPPF products can be used with all the latest fuel injection technologies. Further, FPPF products provide the best solution to water in diesel fuel and gasoline. This is so important, since water remains the number one problem in fuel today.


Basic Definitions / General Problem Solving

First chemical mixtures like Diesel Fuel, Gasoline and other fuels are hygroscopic or they attract water in all forms. The opposite of hygroscopic is hydrophobic or water repelling chemicals. These chemicals cause water demulsification.

Improving Engine Performance with the FPPF Fuel Stabilizer and Diesel Injector Cleaner “New” Detergent Technology

Improving Engine Performance

Peter M Guerra – VP Technology


To realize the benefits of today’s cleaner-burning ULSD fuels and advanced High Pressure Common Rail (HPCR) injection systems, new diesel detergent technology is required to maximize performance. In order for HPCR injection systems to efficiently produce more power and reduce emissions, the fuel is stored in a central accumulator rail under extremely high pressure (25,000 to 30,000 psi). The fuel is delivered to each electronically controlled injector to provide up to 6 injection events of atomized fuel per combustion cycle. HPCR injection systems provide significant performance improvements as a result ofmore specific internal tolerances (2-3 microns) and higher injection pressures. HPCR diesel injection systems provide quieter, more efficient diesel engine performance, but as with most new technologies, HPCR has created new operational challenges for the diesel engine operator. The operational challenge for HPCR injection systems is Internal Diesel Injector Deposits. These deposits are different and distinct from conventional nozzle deposits as they are produced primarily in the injector valve seat but can also be found in the nozzle areas of HPCR injectors.

Diesel Soap Tech Bulletin

Diesel Soap Tech Bulletin

Peter M Guerra


A new troubling phenomenon is occurring at times with Ultra Low Sulfur Diesel Fuel.The problem is called diesel soaps formation.Although not a wide spread problem yet,diesel soaps form when they react with surface active agents such as corrosion inhibitors.

Basically, The corrosion inhibitors that are added by the oil refiners at the rack contain salts that when exposed to water become acidic (actually the salt which is an acid combined with a base chemical separate into ions) These acids : (Dodecenyl succinic and Hexadecenyl succinic acid) react with fuel contaminants to form (soap like impurities) This was never a problem until the introduction of ULSD since these products were held in solution by the higher sulfur diesel fuels. With ULSD they can separate out and react with cations (eg sodium, calcium and other metal salts) commonly found in fuel tank water bottoms. Additionally rust and dirt may provide exchange sites that exacerbate the soap formation process.
