The process of fuel polishing leaves diesel fuel cleaner, purer, drier, and brighter. Foster Fuels can restore fuel that is degraded by contamination or age to a nearly new condition with this process.

Major refiners say that fuel begins to degrade significantly after only 6 months. Many companies and large facilities typically keep fuel in their backup generators, as the equipment is typically only used in natural disasters, for a much longer period than that. Replacing the degrading diesel fuel every six months would be an excessive expenditure for most businesses. Fortunately, fuel polishing can reverse that degradation and save you from costly downtime and expensive damage to your equipment.

Speak To A Fuel Expert

A combination of specialized equipment, appropriate diesel fuel additives, and appropriately sized filters restore fuel in a commercial fuel storage tank to an almost new condition. In addition to a notably visible difference, the quality improves at the chemical level as well. Most importantly, the process maintains the combustion quality of your fuel. We can also facilitate third-party lab testing to confirm that your fuel has been returned to new specifications.


Fuel polishing can remove water and particulate contamination from fuel as well as reverse the effects of aging on diesel fuel in long-term storage. For facilities with zero tolerance for downtime, Foster Fuels recommends that polishing be planned for every third year as preventative maintenance.

Additionally, fuel polishing benefits our environment. By restoring fuel, the process prevents unnecessary waste, because polishing operations typically create less than .001% waste.


Our professionals will begin the fuel polishing process by evaluating the condition of the fuel in your tank. Then, we provide our expert opinion on how to restore it to nearly new condition. We employ experienced technicians with in-depth knowledge of fuel chemistry; therefore, you can trust us with your fuel investment.

Each of your members displayed a willingness to go above and beyond the call to ensure multiple delivery missions to facilities. You kept the principal Aerial Port of Debarkation generations filled for constant use for all Joint Warfighter’s benefit so they could meet mission. Your Emergency Response Team was prepared and again, integrated across the board with key stakeholders.

Matt Ott, CDR, SC, US Navy

The thanks goes out to you and your outstanding crew. I handled life support for the main port in Port-au-Prince, and while Foster Fuels was present, fuel was not just taken care of, but incredibly flexible and adaptive to multiple needs. It was as easy as simply talking with your folks and they leaned forward and took care of the need.

1Lt Travis Michelena, JLC, Haiti

I just wanted to take a moment and commend your company and the fine crew that I had the pleasure of working with during the Kentucky Ice Storms. In my short time with FEMA and working seven major disasters, I have never worked with any contracting team that was more professional and such a pleasure to work with. We faces incredible weather conditions and long hours but I never heard one complaint out of the entire crew. The only thing I heard was what can we do now and how can we better complete and make the mission a success.
