All diesel fuel contains some level of water and particulate contamination from the manufacturing process and the typical nature of the fuel . In addition , these water and particulate levels can increase while in storage due to condensation and the air space changing in the storage tank . When we couple this potential for contamination to naturally be present with the sophistication of today ’ s High-Pressure Common Rail ( HPCR ) engines , we see that it has become increasingly more important that you are using a quality fuel supplier and have a plan for a Fuel Quality Management ( FQM ) program .
A FQM plan is essential for monitoring and removing any of the water or particulate contaminants to keep the fuel as clean and clear as possible while also protecting from thermal and oxidative breakdown . Regular checks for and removing any found water are the backbone for this , along with using the correct filtration to keep the fuel free of particles that are invisible to the naked eye but cause operational issues within the engine . The fuel can also play a part in FQM as well . Dieselex Gold is a diesel fuel designed to help control moisture and provide additional stability of the fuel , reducing the chance of oxidative and thermal breakdown .
The next step is making sure that the engine is running like new and maximizing its performance . Typical # 2 ULSD will develop internal deposits within the engine that rob the engine of efficiencies and power . Dieselex Gold helps by keeping deposits from developing and cleaning up any deposits that might have previously formed in the engine . The corrosion protection and added lubricity aid keep all moving parts in the pump and injectors working properly . The added cetane found in Dieselex Gold delivers a 47 typical cetane number , which is the level that engine manufacturers recommend for getting the combustion timing correct to deliver the most efficient and complete combustion of the fuel in the combustion chamber .
PREVENTING STORAGE TANK CORROSION The U.S. Environmental Protection is responsible for keeping an eye on the integrity of underground fuel storage tanks (USTs) and the potential for leaks. Until recently, the risk of corrosion in diesel fuel storage tanks was considered minor. When it does occur, it is typically found in situations with water present in a wetted layer in the lower portion of the tank. Recently, however, UST owners have begun reporting new incidents of severe and rapid corrosion in the upper portions of their metal underground tanks. While corrosion is expected when water is present at the bottom of the tank, historically it has been highly unusual to see corrosion in the upper portion of the tank. Something changed. The best way to minimize the risk of corrosion is to follow good fuel quality management practices. Tanks should be inspected regularly to identify and remove excess water. Utilizing pre-vent caps to cut down on moisture from condensation and purchasing an additized diesel fuel, such as Dieselex Gold, can make a difference, too. Dieselex Gold is formulated with two components that help in controlling moisture to keep tanks drier for longer periods. It also contains a corrosion preventative that helps protect metal exposed to water or condensation from corroding. Water and corrosion in your tank can cause major problems. If you are regularly plugging filters or suspect water in your fuel tank, call your local FS Energy Specialist. They are equipped with the tools to identify problems and provide economical solutions to keep your operation running smoothly. In 2014, the EPA started conducting research to try and determine how serious and widespread this issue was becoming. They selected a diverse group of 42 diesel fuel storage tanks for inspection and found that 35 of the 42 (83%) tanks showed moderate to severe corrosion of metal components. Ultimately, the widespread increase in corrosion was attributed to the introduction of Ultra-Low Sulfur Diesel fuel. Even though the EPA study was conducted on USTs, there are implications for farm operations with above-ground fuel tanks. As the result of changes in our fuel composition, above ground tanks have been experiencing similar problems with corrosion. It’s not only a problem for the integrity of the tank, but it can create loose particles that can block filters and/or cause damage to injectors or fuel pumps. Meanwhile, corrosion as a result of water on tank bottoms is still a concern, too. Steel corrosion, NACE test. Protected with Dieselex Gold compared to typical ULSD without added protection.
