Why Fuel Management

Your business depends on an emergency generator for electricity when commercial supplies fail.

That emergency generator depends on diesel or kerosene to operate.

When the fuel is contaminated with water, dirt, micro-organisms or other contaminants, the generator will fail and your facility will be without electricity.

Diesel-Clean® fuel management ensures clean, dependable fuel for use in emergency generators.

What is Diesel-Clean® Fuel Management?


  • An effective methodology to first detect contaminants and determine their potential for causing failures.
  • A cost effective, efficient means of removing problem causing contaminants while reducing waste and waste disposal costs and liabilities.
  • Effective methodologies to help reduce recurrence of contaminants.
  • Thorough reports to record effectiveness of fuel management.


  • Biannual S.T.A.R. PLUS sample testing – A highly effective methodology for contaminant detection.
  • Diesel-Clean® purification when test results dictate – A cost effective means of removing problem causing contaminants while significantly reducing both waste disposal costs and liabilities.
  • Diesel-Clean® treatment when test results dictate – An effective means to control micro-organisms and retard oxidfation (aging) inherent with stored diesel.
  • Thorough fuel test reports are provided with every service to record contaminant levels and service efficiency.


  • Diesel-Clean® fuel management is provided by Diesel Fuel Maintenance, Inc.
  • Our company has been providing high quality fuel management services since 1985.

 Why is Fuel Management Necessary?

Emergency generators are the lifeblood of hospitals/medical centers, communication companies, office buildings and many other business interests during power failures.

Hospitals rely heavily upon emergency generators to provide life support olperations as well as communications in the event of a major power failure. As hospitals depend on emergency generators, so do emergency generators depend on clean dependable fuel.

General operating procedures on most generators and installation designs on tanks increase the chance of contaminants not being discovered until they cause generator failures during a critical time.

Environmental regulations require modifications to fuel tanks that can cause contaminants to collect around tank accesses and seep in to tanks. Contaminant seepage has always been possible in fuel storage facilities; particularly, those placed underground.

These facts make a fuel management program extremely important!

 Fuel Management Programs

A fuel management program’s purpose is to keep systems and equipment free of contaminants, A fuel management program consists of a biannual bottom sampling with laboratory testing and purification of contaminated fuel when needed to ensure clean, dependable fuel for emergency generators.

The sampling device used by Diesel Fuel Maintenance extracts bottom samples which identify contaminant levels in the bottom 4 – 6 inches of the tank. This area is where heavy contaminants are agitated and mixed with the fuel during prolonged running of emergency generators or after fuel deliveries. Most foot valves are positioned to draw fuel from an area 4 – 6 inches off the tank bottom.

The importance of bottom sampling has increased with the installation of tank monitoring systems using probes which extend to tank bottoms. Fuel contaminants which accumilate in tank bottoms can hinder these monitoring system’s efficiency. In fact, some manufacturers of these systems recommended keeping tank bottoms clean to help ensure the monitoring sysem’s accuracy.

Clients receive a computer generated test report and work summary for each tank serviced. The report and summary include pertinent tank information, a complete account of all work done and specific tank readings for each type of service.

Recommendations are also included for further stored fuel management to ensure fuel cleanliness and dependability in the future.

These programs effectively manage fuel all over Texas. They can be designed to fit a client’s needs and budget. Contact us for more info.

Recommended Fuel Management Practices

ASTM D975 “Standard specifications for Diesel Fuel Oils” is the standard for diesel fuel quality. ALWAYS refer to ASTM D975 when making a fuel management decision.

Select the best fuel available for long-term storage STABILITY and for PERFORMANCE in your emergency generators, rather than for the price.

1 – Request “refinery Prduct Specifications” from your supplier, and when possible request “straight run” distillate fuel. Annual “Accelerated Stability” test (DuPont F21-61) should be run on all tanks.

2 – Have employees do a “Clear & Bright” test (ASTM D4176) before bulk of fuel is dropped. Reject cloudy, extremely dark fuel or fuel with sedimentation, and let your supplier know in advance that you will reject such fuel.

Periodic sample testing is an essential step in monitoring fuel quality.

1 – Annual testing for selected “Qualitative Refiner’s Specifications” appropriate for diesel generators should be compared with original “Refinery Product Specificationss” provided by your supplier to determine whether fuel quality is adequate for your generators.

2 – Biannual testing for contamination and fuel degradation utilizing “Bottom Sediment and water (BS&W) – ASTM D1796”, “Particulate Filterability”, and “Microorganism Growth” tests (S.T.A.R. Plus) to determine contamination levels and possible effects on generator and fuel monitors.

Purify contaminated fuel when testing reveals that existing fuel does not meet ASTM D975 specifications.

1 – Military proven mechanical separation technology only process that will remove 100% of the contamination.

2 – Consult your Fuel Specialist before selecting additives or bioloical treetment to affect fuel quality or contamination.

Keep tanks at least 80% full. Less air and water in the tank is less habitat for microbial growth.
