Have you ever looked into your fuel tank and noticed a dark brown or black color? Have you noticed a bad odor, similar to rotten eggs? If you have, then your diesel has turned into slime. According to Conidia, the cause of this unfortunate occurrence is credited to a fuel infection known as a diesel bug. If left untreated, this infection could cause adverse effects on your vehicle’s fuel system.
Read on to learn more about diesel bugs.
What Is A Diesel Bug?
A diesel bug is a single or group of microorganisms that typically grow in fuels. They include bacteria, yeast, and mold with filaments. Diesel bugs usually feed on hydrocarbons in fuels. They create by-products like biomass and biofilms that form a coating on the surfaces of fuel tanks and pipes. If this coating is not removed, causes can damage engines and machinery. Diesel bugs can dwell even in the smallest amount of water. Therefore, when condensation occurs in fuel tanks or when fuels are exposed to water, diesel bug infestation increases.
How Does A Diesel Bug Form?
Most diesel bug infections usually result from condensation in fuel tanks. When condensation happens, water forms in fuel tanks. As explained earlier, even a small amount of water can create a breeding ground for different kinds of bacteria. You can prevent excessive condensation in your fuel tank by utilizing good fuel management practices, like using quality diesel and ensuring the tank cap is sealed tight. Inspecting your fuel tank regularly also comes in handy in preventing severe diesel bug infection.
How Can You Recognize A Diesel Bug Infection?
A diesel bug infection may be hard to notice if you do not test your fuel regularly. However, as the problem worsens, you will start recognizing some clear symptoms of a diesel bug infection;
Poor Engine Performance
Many things can cause poor engine performance, like structural issues. However, poor engine performance can also be a symptom of diesel bug infection. The infection restricts the amount of fuel that reaches the engine and causes poor performance. In worse cases, it can cause engine failure.
The Increased Fuel Consumption or Wastage
When your engine is struggling to deliver, it uses more fuel than usual. If the situation isn’t controlled, you’ll take more trips to the gas station. Besides, severe diesel bug infection could cause perforation in your fuel system, resulting in leakages.
Blocked Filters
The biomass and biofilms resulting from diesel bug infections can enter the engine filters, resulting in blockage. The blockages hinder the fuel from flowing into engines, resulting in poor performance and possible engine failure.
Leaking Tanks
Diesel bug infections can cause corrosion in fuel tanks. The corrosion may lead to holes and cracks forming in the fuel tanks. This results in fuel leaking from the tanks. Additionally, when the corrosion occurs over time, it causes structural damage to other elements like injectors and filters.
Foul Smell Or Black Smoke From Exhausts
If a diesel bug infects your fuel tank, you will start noticing black smoke and a bad smell from the exhaust. A diesel bug infection also emits a rotten egg smell. When the infected fuel goes through the engine and gets heated, it forms foul-smelling and uncharacteristically black smoke.
Note: Most of the symptoms above are usually signs of significant damage from a diesel bug infection. The best way to resolve this issue is through expensive mechanical intervention. Some downtime for cleaning the tank and the fuel system can also help.
How To Prevent A Diesel Bug Infection
Every issue in a vehicle is preventable, and so is diesel bug infection. The following actions will come in handy.
Fuel Maintenance
You can prevent a diesel bug infection by establishing a regular fuel maintenance plan. Your maintenance plan should include strategies for removing water, debris, and dirt from your fuel. Removing water will help prevent a diesel bug infection.
Regular Tank Inspections
Regular fuel tank inspections can also help prevent diesel bugs. The inspections will help you catch the infection before it becomes severe. For instance, you will notice the slime and foul smell from the infection during inspections. This allows you to resolve the issue before it causes severe structural damage to your fuel system and tank.
Frequent Fuel Testing
You can also check for diesel bug infections by testing your fuel. There are many diesel bug testing kits on the market that you can use.
The best way to recognize a diesel bug infection is by testing your fuel often. This way, you can catch the infection and establish ways to resolve the issue and avoid it in the future. If your fuel is already infected, you can kill it by using the right diesel bug treatment.
