What we can offer you

Fuel Polishing

FuelStat provides commercial fuel polishing for all long term diesel storage.

Our state of the art equipment will bring your fuel back to new or better standards at a fraction of the cost of removal and replacement.


As of July 1st 2016 the new CSA code B139 Series-15 states that all long term fuel storage for life safety buildings has to be tested annually and meet certain standards set out in the code. If the fuel does not meet these standards the fuel has to be replaced or actions have to be taken to remediate the fuel quality. We have licensed technicians take the sample from your site and have it sent to a 3rd party laboratory for testing.

Fuel Polishing Service Contracts

FuelStat offers custom service contracts to suit the individual needs of any client. Most of our clients that choose to go with this option manage multiple properties and appreciate the peace of mind in knowing their fuel will always meet the standards set out in the code. Also properties that need their equipment to run without question for example hospitals, military, government buildings, banks, data centres most of these type of clients take advantage of our contract pricing and peace of mind.

Most diesel engine failures originate in the fuel tank. Many articles have been written, and many opinions are voiced about how to maintain diesel fuel quality, as well as what to do about diesel fuel that has "gone bad". Many companies offer a version of diesel fuel polishing with varying claims, but with little substance to support these claims. FuelStat has state of the art equipment with a patented design that eliminates the need for fuel additives and brings your fuel back to new or better standards.

The popular term for treating diesel fuel is Fuel Polishing. Many vendors hype their product or process that "polishes your fuel" and returns it to usable quality. Most all of these processes depends heavily on the addition of chemicals -- treating microbial contamination with biocides. They also make extensive use of filtration systems. Many mechanics that see fuel problems, however, just add another Racor (some installations have two or three lined up in series on the fuel line) and/or a series of finer fuel filters (starting off with 30-micron, and working down to 10-micron or 3-micron filters).

Others use novel filtering media, such as paper towels or some other "proprietary" means of removing solids from the fuel. But these approaches only treat the symptoms of the problem. Also, repeated use of biocides in the same fuel often exacerbates the problem, i.e.: further degrading the fuel at the molecular level.

A separate but equally perplexing problem is the natural degradation of diesel fuel. A diesel engine uses only some of the fuel it pulls from the tank. All of that fuel goes through the high-pressure fuel pump and to the injectors operating under enormous pressure and high temperatures. The surplus fuel the engine is not using goes back to the tank. This fuel is continuously re-circulated and exposed to extreme pressure and heat, which results in the agglomeration of asphaltenes, the high carbon content, heavy end fuel molecules. It leads to the formation of larger and larger clusters and solids, which are very difficult to completely combust. These solids may grow so large that they will not pass through the filter element. They become part of the polymer and sludge build up plugging the filter.

In addition, the hot fuel coming back to the tank will raise the fuel temperature in the tank, cause condensation (water accumulation in the bottom of the tank) and contribute to microbial contamination, fuel break down, bio fouling and the build up of sludge and acid.

Note that fuel in storage for long periods show this same darkening of the fuel. Most diesel fuel is consumed within a couple months of leaving the refinery, but fuel in storage, such as for back up power generator service or companies or farms that have fuel tanks that receive refills only a couple times per year (or less) suffer from the darkening of the fuel. Over time, depending on the quality of the fuel, and even with vigilance in keeping water out of the tank, the fuel will degrade and turn dark. This happens naturally as the asphaltene components in the fuel that is in solution attracts other asphaltenes and grows in size until the fuel is dark and these components drop to the bottom of the tank. If you have ever seen the inside bottom of an old fuel tank that looks like it was painted with roofing tar, you have witnessed the results of this process.

Today's advanced engine designs also contribute to diesel fuel reduced stability. Poor thermal fuel stability can plug filters. Fuel will form particulates (solids) when exposed to pumps and the hot surfaces and pressure of the fuel injection system. This will result in an increase in asphaltene agglomerations, polymerization and a dramatic loss of combustion efficiency.

Fuel is an unstable, organic liquid that goes "bad". Your vendor will always sell you the highest fuel quality possible. However, due to a variety of circumstances fuel may have "aged", oxidized and/or may contain water. It may have been contaminated before it was delivered to you or to your vendor.

Fuel has to travel from the refinery to the end user destination. It is pumped through pipelines, barged, trucked and stored in tank farms. Changes in temperature throughout any given day and exposure to the atmosphere will cause condensation and water in storage systems. As a result, your fuel quality diminishes.


Working together

FuelStat works closely with property managers who manage anything from 1 building to 200 sites as well as government and military. Many of our clients choose our multiyear fuel polishing service contracts, it saves them time, money and keeps them TSSA. compliant. FuelStat only uses OBT. and TSSA. licensed technicians on site as most insurance companies require anybody working on equipment with on site fuel storage be qualified to do so.

As of July 1st 2016 the new code update enforced by TSSA states all diesel stored long term for emergency generators has to meet certain standards set out in the code. FuelStat uses a 3rd party independent laboratory for all our testing. We offer packages that test for everything you need to be TSSA. compliant and make sure your fuel meets the standards set out in the code.

Contact us today to discuss a long term fuel storage solution for your property.


"We recommend FuelStat to all our customers not only because it's required by the new code but we have peace of mind knowing all their site crews have the appropriate licenses and insurance to deal with diesel fuel."
