Water in diesel fuel causes engine issues
Water in diesel fuel can cause serious engine issues. While diesel fuel will always contain a certain percentage of water, excessive water can cause significant damage to fuel quality and engine performance. Water can enter the fuel during transit, storage, or handling, and it is important to recognise and treat the issue to keep your engine running in top condition.
Water in diesel fuel can lead to a range of issues, from rough starting and erratic idling to complete engine failure. One of the most common issues is clogged fuel filters, caused by the formation of a soft solid when water combines with certain chemical molecules in the fuel. This soft solid can also create engine deposits. Water can also cause fuel pumps and fuel lines to freeze, especially in cold weather, leading to a range of new engine issues.
Another issue caused by water in diesel fuel is microbial growth. Bacteria, fungi, and other microbes need water to survive, and they can multiply rapidly in the presence of free water, creating slimes that foul your fuel and acids that corrode your tank and fuel system. This can lead to fuel tank rust and corrosion, as well as clogged fuel filters. Once bacteria are present in the fuel tank, removing the water is only half the battle; the bacteria must also be killed to ensure the diesel fuel is safe to use.
Water in diesel fuel can also cause oxidation reactions, which lead to the formation of acids, gums, and sediments known as fuel degradation products. These reactions can darken the fuel and cause varnishes and sludge to drop out of it. This can result in engine deposits and contribute to fuel system wear and tear.
To prevent water-related engine issues, it is important to regularly treat diesel fuel with water-dispersing formulations and to keep water levels within acceptable limits, well below the saturation point. Monitoring water content and evaluating the results are crucial to developing an effective water management strategy. While some water removal methods can be done onsite, laboratory tests like the Karl Fischer titration method can provide highly precise measurements of water content.

Water in diesel fuel can lead to corrosion
Water in diesel fuel is a common issue that can cause serious problems for your engine. Water can enter the fuel during transit, storage, or handling, and it is important to treat it properly to prevent issues. One of the biggest concerns regarding water in diesel fuel is the potential for corrosion.
Corrosion is an issue that develops over time as water accelerates oxidation and rust formation on metal parts. This can affect fuel distribution, ruin fueling lines and systems, and lead to fuel filter clogging. Water in diesel fuel can also cause fuel degradation, resulting in darkened fuel with gums, varnishes, and sludge. This sludge, or particulate accumulation, can be identified through regular visual inspections and filter inspections.
The Environmental Protection Agency (EPA) has found that many tanks show no visible signs of corrosion, yet over 80% have moderate to severe corrosion. This highlights the importance of regular maintenance and inspections to prevent corrosion-related problems, which can lead to significant safety risks and costly repairs. While water monitors can be used as a line of defense, human inspection is crucial for confirmation and a comprehensive understanding of the tank's condition.
To prevent corrosion, the EPA recommends controlling water in tanks, filtering the fuel for water and particulates, using biocide and anti-corrosion chemical treatments, and partnering with service companies for tank damage repairs. Additionally, it is important to understand how to measure water content and evaluate the results to develop an effective water management strategy.
In summary, water in diesel fuel can lead to corrosion, causing significant damage to fuel quality and engine performance. Regular inspections, proper water management, and the use of chemical treatments are essential to prevent corrosion and maintain the integrity of diesel fuel storage tanks and engine systems.

Water in diesel fuel can cause microbial growth
Water in diesel fuel can cause several problems, including microbial growth, commonly known as "diesel bug". Diesel fuel will always contain some percentage of water, and this water provides the perfect environment for microbes to grow and reproduce, leading to fuel degradation over time.
Water can enter diesel fuel through various means, such as condensation, rainwater penetration, or adsorption from the air. Modern biodiesel is especially hygroscopic, meaning it has a high capacity for absorbing water. As a result, water can build up in fuel tanks, creating favourable conditions for microbial growth. These microbes, including bacteria and fungi, reside at the interface between the oil and water or on the tank walls, depending on their oxygen requirements. Species that may grow in this environment include bacteria such as Clostridium, Desulfotomaculum, and Pseudomonas, as well as fungi such as Aspergillus and Candida keroseneae.
The presence of microbes in diesel fuel can lead to the formation of biomass and slime growths, which can plug fuel filters and cause other issues in the fuel system. These clogged filters can break, leading to unnecessary costs and potentially causing the engine to shut down. Additionally, microbial growth can affect the pH of the fuel and contribute to tank corrosion.
To prevent microbial growth in diesel fuel, it is essential to minimise the exposure of the fuel to water. This can be achieved through procedures such as fuel recycling, routine discharge of water bottoms, and fuel tank insulation to stabilise fuel temperature. Regular tank inspections, cleaning, and treatments are also recommended. In cases where sludge or biomass has already developed, it is crucial to remove it promptly and regularly to prevent further growth. Treatments with diesel fuel biocides or diesel microbial growth removers can be effective in preventing and addressing contamination.
Water in diesel fuel can lead to other issues beyond microbial growth. It can cause fuel degradation, engine performance problems, and even engine failure. Water can freeze in diesel fuel during colder months, leading to issues such as frozen fuel pumps and lines. Water also accelerates the oxidation and breakdown of fuel, resulting in darkened fuel with gums, varnishes, and sludge. Therefore, it is essential to manage water content in diesel fuel through proper treatment and prevention methods to maintain optimal engine performance and avoid costly repairs.

Water in diesel fuel can be removed with chemical treatments
Water in diesel fuel is a common issue that can cause serious damage to your engine. Water can enter the fuel during transit, storage, or handling, and it is attracted to and absorbed by diesel fuel at the molecular level. This can lead to a variety of problems, including engine damage, reduced fuel efficiency, and corrosion.
One way to remove water from diesel fuel is through chemical treatments. There are several chemical control options available, including additives that can help to demulsify the water from the diesel. These additives cause the water to separate from the fuel, allowing it to be removed through mechanical means. Some examples of chemical treatments include:
- FPPF products such as Fuel Power can effectively remove water from diesel fuel.
- Bell Performance has developed chemical treatments for decades, including multifunction formulas and single-function problem solvers that can help emulsify the water, combining it with the diesel fuel in tiny particles (micelles) that are suspended in the fuel.
- DFS Plus and Cold Flow Improver utilize absorbing technologies that seamlessly bind water into the fuel, preventing it from dropping out.
It is important to note that modern diesel engines typically do not want water suspended in the fuel, so demulsifying additives may be a better option. Additionally, a combination of mechanical and chemical approaches may be necessary to effectively remove water from diesel fuel.
While chemical treatments can be effective, preventing water from entering the fuel in the first place is ideal. This can be achieved by filling up diesel fuel tanks to their capacity, maintaining proper storage conditions, and regularly inspecting and measuring water levels.
