What You Don't Know About Diesel Fuel...Can Hurt You
8 Out of 10 Diesel Engine Failures Are Related To Poor Fuel Quality or Contaminated Fuel

old fuel vs clean fuel

  Reverso's stored diesel consultants can develop a solution to help you eliminate sludge and water build-up in fuel tanks, reduce the cost of filter maintenance and provide continuous operation to your critical power components.  
  Misconception #1: Diesel fuel "going bad" is an urban myth or marketing ploy.   Misconception #2: Bad fuel is not an issue in the USA.   
  Fact: Within 30 days of refining, all diesel fuel regardless of brand, goes through natural processes called re-polymerization and oxidation. This starts the process that causes sludge to be formed.  

Although diesel fuel should be fine for six months in normal conditions (no extreme weather or water contamination) the quality will degrade quickly after one year.  

Reduced fuel quality causes decreased power and RPM, pitted/clogged injectors, engine stuttering and stoppage, corrosion of injection pumps and engine stalling.  

Fuel polishing in conjunction with a combustion catalyst will maintain the quality and usability of your diesel fuel.

  Fact: All refined diesel fuel, even in the US, contains some suspended water and solids. The settling process now occurs in your tank, not at the refinery. 

And refinery techniques produce a lower-grade fuel than today’s engines need to operate at their optimal level. 

Plus, you no longer have tight control over the fuel distribution methods. You don’t know the quality of tanks the fuel has passed through nor whether biodiesel or contaminated fuel has entered the supply chain before the fuel gets to you.

There is no guarantee the fuel you receive is “clean”.

  Misconception #3: Water contamination can be taken care of with additives that emulsify the water.    Misconception #4: The filter already installed will take care of any water or particulates that might cause damage to the engine.

Fact: Emulsified water (caused by various additives) actually causes greater harm to the engine than just water. Water causes an engine to shut down but the engine can be cleaned, the oil changed, and then function again.

However, emulsified water in fuel can be partially combusted but not effectively – thereby damaging the engine. It also reduces the lubrication provided by the fuel, necessary for the fuel pump.

This wear and tear on the engine, rings, pistons and valves causes excessive abrasion, corrosion, carbon deposits, pitting and premature ageing of the fuel pump.

It is better to de-emulsify water, making the water molecules larger so they bond together, so that the water will drop to the bottom of a tank and then can be easily removed via fuel polishing. 


Fact: The filter you probably have installed is a secondary filter. If you store fuel, you always need a primary filter (fuel/water separator) in front of the lift pump.  

Even with a primary installed, the filter only addresses the symptom – not the problem. A filter is a controlled failure point. If it clogs, it did its job. But then your engine stops. Can you afford that downtime?  

Fuel polishing takes the failure point to a place in the process where it is manageable through maintenance. Thereby eliminating engine failures or disruption of business.
