Cummins and Power Service - Two Names You Can Trust


One hundred years and counting, Cummins has long since been legendary with its diesel engine manufacturing. It is no mistake that Cummins would endorse Power Service and add their diesel fuel additives to their broad portfolio of power solutions. Power Service, a third-generation veteran and family-owned company, shares the same mission as Cummins, and that is to provide the most technologically advanced products and services that power the future and improve people’s lives.  

Cummins’ commitment to developing not only engine design, but the turbochargers, fuel system, and after treatment systems, perfectly match the defining qualities of Power Service’s esteemed product line of diesel fuel additives. You can’t have peak performance with your diesel engine unless it is maintained with the proper products. These year-round enhancers are a game-changer in the fleet industry.

With the evolution of the diesel engine, fuel additives have never been so important. The two power service products for use in diesel engines - Diesel Kleen +Cetane Boost and Diesel Fuel Supplement +Cetane Boost, were officially endorsed by Cummins, a partnership that did not happen overnight. “When Cummins and Power Service began to discuss the endorsement partnership, it was a culmination of 60 years of hard work and dedication to developing the most consistent and effective diesel additives on the market,” said President of Power Service Products, Ed Kramer. “This partnership is a confirmation of Power Service’s continued commitment to our customers and to the entire industry.”

This stealthy collaboration of two powerhouse companies are making fuel solutions more accessible to customers over a wide distribution network and Robert England, Director of Technical Quality and Materials Engineering for Cummins, Inc., ...says this pairing is perfect timing for today’s more advanced engine systems. “In recent years diesel fuel quality has become increasingly important as engines evolve and the diesel fuel manufacturing processes change. The Power Service Diesel Fuel Supplement additives provide easily-accessible solutions with proven technology to customers in the field.”

Diesel Kleen +Cetane Boost and Diesel Fuel Supplement +Cetane Boost & Bio Kleen Diesel Fuel Biocide 

Diesel engines withstand a lot of wear and tear. Proper maintenance is essential for peak performance. Knowing your product application is also key. Listed here are primary functions of the two main diesel fuel additives. Lastly, we will discuss the preventative product lines that Power Service suggests for further optimum engine performance. 

Performance - Diesel Kleen +Cetane Boost

This total injector cleaner enhances engine performance by cleaning injectors, boosting cetane and lubricating fuel injection components. Cleaner-burning fuels are requiring new technology and Power Service answers the call with this product. Maximizing engine performance is the main goal and Diesel Kleen +Cetane Boost is just what your engine needs to restore lost power and fuel economy, and smooth rough-running engines. Year-round maintenance and Power Service products go hand-in-hand. Use this product every time you fill up when the temperatures are above 30 degrees Fahrenheit, and you will keep your diesel engine in tiptop shape. This however, is not to be confused with the winterizer or anti-gel. An easy way to remember is summer equals silver packaging and winter equals white packaging. The Diesel Fuel Supplement +Cetane Booster is necessary for maximum winter protection for your diesel engine.  


  • Cleans dirty injectors and prevents injector sticking in both High Pressure Common Rail (HPCR) and older systems
  • Removes deposits on fuel injectors
  • Boosts cetane up to 6 numbers – engines run smoother with less power lag and faster cold starts
  • Boosts power – reduces need for downshifting
  • Restores lost power and fuel economy
  • Contains Slickdiesel® Lubricator to protect fuel pumps and injectors from increased wear caused by Ultra Low Sulfur Diesel (ULSD) fuel
  • Effective in all diesel fuels, including ULSD, biodiesel and biodiesel blends

Winterization - Diesel Fuel Supplement +Cetane Boost

In the cold winter months when temperatures drop below +30F, a winterizer, anti-gel product is needed. This is to prevent fuel gelling and keep fuel filters from getting clogged with ice and wax. This wax build up will block the fuel flow while hindering engine performance. Using the specially formulated Diesel Fuel Supplement +Cetane Boost will keep your diesel engine running for trouble-free winter operation. Remember, white (containers) equals winter.


  • Prevents fuel gelling
  • Protects against fuel filter icing
  • Boosts cetane for faster cold starts
  • Contains Slickdiesel® Lubricator to protect fuel pumps and injectors from increased wear caused by today’s Ultra Low Sulfur Diesel (ULSD) fuel
  • Effective in all diesel fuels, including ULSD and biodiesel blends

Fuel Tank Hygiene - Clear-Diesel Fuel and Tank Cleaner

As we continue to list the many benefits of keeping a yearly maintenance schedule for your diesel engine, it is important to discuss preventative measures. As mentioned before, cleaner-burning fuels have lower sulfur content, allowing for water separation, contamination and are widely unstable. This “Fuel Polishing Formula” removes water and slime, disperses contaminants and helps keep fuel stable during long-term storage. This can be a quarterly service or as needed, but can also be used for immediate cleanup of equipment and fuel storage tanks.


  • Disperses diesel fuel contaminants
  • Removes water and slime
  • +Petrofresh provides maximum long-term storage stability – keeps fuel fresh
  • Prevents premature fuel-filter plugging
  • Protects against fuel tank corrosion
  • Effective in conjunction with Bio Kleen Diesel Fuel Biocide to remove residual water and contaminants during microbial contamination cleanups
  • Effective in all diesel fuels, including Ultra Low Sulfur Diesel (ULSD), biodiesel and biodiesel blends
  • Does not contain alcohol of any kind
  • Safe for use in all diesel engines

Bio Kleen Diesel Fuel Biocide

So far, we have discussed diesel engine maintenance in all types of weather, as well as keeping your fuel tanks free of slime and contaminants. Now, we will outline the benefits of Bio Kleen Diesel Fuel Biocide. Lower sulfur content in today’s diesel fuel is becoming a breeding ground for microbes in fuel tanks. Bacteria and fungus grow more rapidly than in higher sulfur fuel. In fact, the more paraffin wax that is replacing the sulfur content is exacerbating the microbial contamination problem. Indications of this microbial growth include mucous-like accumulations on fuel filters, which will require more fuel filter replacements. The only way to get rid of this contamination is with a biocide.  Power Service is here with the rescue again with their specially formulated diesel biocide.


  • Dual-Phase – effective in both diesel fuel and water
  • Effective as a “quick-kill” biocide and for long-term diesel fuel maintenance
  • Kills microbes (bacteria and fungus) that grow in dispersed and free water associated with diesel fuels
  • Prevents fuel-filter plugging – helps prevent fuel system failures
  • Protects fuel system components against organic acids created by microbial growth – prevents fuel tank corrosion
  • Improves fuel performance
  • Reduces engine maintenance costs
  • Effective in all diesel fuels, including Ultra Low Sulfur Diesel (ULSD), biodiesel and biodiesel blends
  • Does not contain alcohol of any kind
  • Safe for use in all diesel engines
