Diesel Tank Cleaning & Fuel Polishing

Diesel Tank Cleaning & Fuel Polishing – What's Beneath The Surface?

So, you have a Bulk Diesel Fuel Storage Tank on your property that you’re using to provide your fleet or equipment with diesel? Or, you may have a backup power generator with a fuel storage tank that tends to sit for long periods of time with irregular use? We talk a lot about Fuel Tank maintenance and the importance of keeping your diesel fuel clean and free from contaminates. 

That backup power generator needs to work when that emergency strikes. The impacts of dirty fuel on your fleet can be devastating to your bottom-line profits. These issues range from fuel injector damage, clogged fuel filters, loss of power, engine shutdown, poor fuel economy, and a general loss of reliability which leads to productivity losses.

Where does this contamination come from?

90% of the contaminates that plague your diesel fuel quality are from organic debris that stems from the breakdown of the fuel. It’s not inorganic sand, or stones that clog your filters. Technically sand would actually help the filtration process. This organic debris is “Algae” and it forms at the bottom of your tanks. Algae is also commonly referred to as sludge, or mud. It starts with the water in the bottom of your tank. Water is the enemy and keeping it out of your Bulk Tank is key.


Fuel Logic has a full range of diesel tank cleaning and fuel polishing services that include above ground Bulk Fuel Storage Tanks, Job Site Fuel Tanks, as well as Generator Fuel Maintenance Programs.
Diesel Tank Cleaning


The process starts with pumping all the water, sludge, and other contaminates out from the bottom of the tank. You then need to start the diesel fuel filtration process that should include 3 levels of filtration. During this filtration process, you begin to introduce chemical cleaners to remove varnish and sludge. Fuel needs to be treated with chemical conditioners including fungicide, algicide, and fuel stabilizers to enhance the life and ongoing performance. Now your fuel needs to be polished.


There’s still one more step to complete after diesel tank cleaning and filtering your fuel. It’s the “Fuel Polishing” process. Fuel Polishing is the process of removing water, sediment, and microbial contamination from diesel, red diesel, and bio diesel. This contamination is known by many names including diesel bugs, fuel bugs, and algae. Didn’t we just filter the fuel, and shouldn’t that be enough? What’s the difference between polishing and filtering? Filters remove suspended particles from the diesel fuel. Fuel polishing takes it a step further using centrifuges, coalescers, and special water blocking filters to reverse oxidation, and separate anything that is entrained, and noncombustible from the diesel fuel.
