Now picture filling up your car just like you normally do. The car runs pretty well until you begin to run a few miles from the starting point and your engine begins to falter. Maybe the car stalls or the engine warning light comes on. You begin to ask yourself, “What is wrong with him? Fuel contamination could be the cause. While many drivers don’t think about a contaminated fuel system, it can have an impact on your vehicle’s starting, running, and performance.
The good news? Early detection of these will prevent major engine damage.
This guide will help you understand what contaminated fuel is, what it does to your car and what you can do if you suspect that you have a problem.
What Is Contaminated Fuel?
Contaminated Fuel by unwanted substances or with an unsuitable fuel or fluid added.
Clean fuel is essential to efficient running. Foreign items that get into the fuel system can disrupt combustion and fuel delivery.
Common contaminants are water, dirt, rust, sediment and incorrect fuel types.
For instance, if petrol is placed in a diesel engine, it can form a mixture that can affect crucial engine parts.
Likewise, water in a diesel tank can also impact on engine performance and lead to corrosion.
The effects vary according to the contaminant, its concentration and its presence in a running engine.
What Causes Fuel Contamination?
Fuel contamination may occur due to various reasons. Some are caused by simple human error and others occur without the driver realizing they are developing.
To use the wrong fuel by mistake.To use the wrong fuel without intention, carelessly.
1. Giving “the wrong” fuel to the cars is a common way of contaminating fuel.
Petrol decreases the lubricating effect of the diesel fuel on some parts of the fuel system. Therefore, it is important to avoid running a diesel engine on the wrong mixture, or parts of the system can be damaged by this.
2. Water in the fuel tank.
Bad storage practices, damaged seals, and contaminated fuel can allow water to get into fuel.
Water cannot give fuel characteristics which are required by your engine, unlike petrol and diesel.
Can also cause corrosion and fuel system issues.
3. A. Dirt and Rust Particles
Over time, storage tanks and fuel systems may accumulate debris.
These particles can clog filters and disrupt fuel injectors when they get into the fuel.
This can make it difficult for your engine to get the right fuel.
4. AdBlue -Incoming to the Diesel Tank
On vehicles with selective catalytic reduction (SCR) systems, AdBlue should be stored in a separate tank.
If accidentally poured into the diesel tank, it can cause serious problems.
So don’t start the engine and call for professional help right away.
Seven Warning Signs of Contaminated Fuel
Symptoms of fuel contamination are not always present. But there are some warning points to be noted.
1. Difficulty Starting Your Car
If your engine doesn’t start up like it used to, is it the problem?
Contaminated fuel may interfere with combustion or fuel delivery. Sometimes, the engine is not able to start at all.
2. A sudden loss of power.
It could cause problems in your car while accelerating or going up hills.
This can occur if the fuel mixture fed into the engine is not the right one or if it is not provided in sufficient quantity.
3. Engine Misfiring
Another reason that your car might be shaking or stalling while driving may be due to fuel contamination.
Genuine symptoms could, however, be caused by faulty mechanical components, such as worn spark plugs.
4. Unusual Exhaust Smoke.
If it is smoke that comes out of the exhaust that you were not expecting, it could mean that it is not a complete combustion.
Be aware if this begins immediately after refuelling.
5. Engine Warning Light
Today’s cars are equipped with sensors that will alert you to issues.
If there is any contamination of the fuel, the fuel light may come on, but the cause of the contamination must be identified by diagnostic testing.
6. Engine Stalling
An engine could be hampered if the fuel is contaminated.
If your vehicle stalls unexpectedly, don’t repeatedly attempt to restart it.
7. Rough Idling
If an engine vibrates excessively or runs poorly when not moving, the engine could have a fuel delivery problem.
If the following symptoms are experienced after refueling, book a professional check-up.
What Should You Do If You Suspect Contaminated Fuel?
What you do next can make a difference.
Step 1 Stop driving safely,
Look for an appropriate area out of the way of moving traffic. When stopped, turn off your engine.
Step 2: Avoid restarting
Restarting can cause more contaminated fuel to be circulated through the system.
Step 3: Recall the refueling location.
If possible, retain a copy of your fuel receipt. It can help determine the time frame of onset of the problem.
Step 4: Call a fuel recovery expert
Describe the symptoms and state if there has been a recent refuelling or an inadvertent fueling error.
Step 5: Schedule a business assessment
A tech can determine if fuel needs to be drained, system flushed or further mechanical inspection is due.
Avoid siphoning petrol. Fuel vapour may be flammable and harmful if not handled properly.
Can Contaminated Fuel Damage Your Engine?
Yes. In some cases, contamination may impact multiple aspects.
These include:
- Fuel pumps
- Fuel injectors
- Fuel filters
- Fuel lines
- High-pressure diesel systems
For instance, water can cause corrosion and dirt can impede fuel flow.
If the contamination is caused by petrol, it can affect the lubrication and lead to component wear in a diesel car.
But not all contamination events cause permanent damage.
If the problem is found before turning on the ignition, then fuel clean-up can help avoid larger issues.
How Do Professionals Remove Contaminated Fuel?
A professional fuel recovery service is an orderly process.
The first thing the technician does is inspect your car and ask what went wrong.
Then they locate the suspected contamination, and determine if the engine has been started.
They then use specialist equipment to drain the contaminated fuel from the fuel tank.
Depending on the situation, extra flushing of the fuel system, or replacing fuel filters, may be required.
Lastly, the car may be refueled with the right type of fuel and have all necessary inspections done before it is put back into service.
There are some cases that can be solved on the road. Others may need repairs at the workshop, especially where there has been contamination of fuel which has compromised parts.
