​Diesel ​Fuel Supply & Filtering

Preventing these problems is a 5-step process. 

  1. Inspect the diesel fuel, tanks and fuel systems regularly. 
  2. Filter and purify diesel fuel that has been stored for over six months. Also, have the tank cleaned or flushed periodically. 
  3. Remove water regularly from any fuel storage tanks or equipment fuel systems. Microbes require only trace water to grow rapidly, so removing water may seem like a hopeless task. Yet, when coupled with the other steps, microbial growth is minimized.
  4. Keep fuel cool. The warmer the fuel gets, the faster it decomposes and the faster microbes form. 
  5. Use additives to help stabilize fuel and prevent microbial growth.

Since there are two causes for diesel fuel problems, two additives are needed to help minimize these problems. A fuel stabilizer will prevent the fuel decomposition, while a diesel fuel biocide will help prevent microbial growth.


No matter what biocide you use, make sure it has an EPA registration number. Otherwise, it is not an effective biocide. All fuel biocides must have the EPA registration number on the label indicating they have passed a rigorous test by the EPA and all the label copy has been approved by the EPA.


Although prevention is the best tactic, these products can be used in higher concentration to "shock" systems that already have deposits. This will remove some of the microorganisms and by-products of decomposition, but the fuel system will still require considerable clean-up work.


"An ounce of prevention is indeed worth a pound of cure." ~Benjamin Franklin


Diesel fuel decomposition and microorganism development can cause disastrous field breakdowns if not prevented. Proper fuel and fuel system maintenance and use of certain fuel treatment additives require minimum effort, yet provide maximum results. Performed properly, the actions recommended here will be very effective in helping to keep your fuel clean and your equipment running smoothly. These and other preventative actions will help maintain your investment in equipment and storage systems while minimizing any problem that could occur because of bad fuel.
