So what is fuel polishing? Simply put, fuel polishing is a way to process your fuel to make it usable once again. This process is a specialized one that will optimize your most valuable resource.

Our Fuel Polishing Process

At Green Coast Fuel Management, our process represents the pinnacle of efficiency in restoring fuel integrity.

We bring our filtration equipment to your fuel tank. Once on site, we begin the implementation of our respected and highly efficient approach to fuel polishing.

Our fuel polishing system begins by removing the water from both low ends of the tank. We then run the fuel through a separator to remove the freestanding water from the “good” fuel. In the case of heating oil and diesel fuels, we use a diesel fuel additive called a biocide, and place that in the tank to kill off any unwanted contaminants and microorganisms. This initial process will remove 99.9% of all water from the fuel.

Next, the fuel is processed through a series of filters that remove virtually all-remaining particulate matter, down to 1 micron. Tank agitation will then remove any remaining sediment that has built up inside the tank wall.

We remove all contaminants as this process continues. Finally, to return the fuel to its true octane rating, fuel stabilizer is added.
