What You'll Learn
Avoid refuelling when a tanker is at the service station
It is recommended to avoid refuelling your vehicle when a tanker is at the service station. This is because the process of refuelling stirs up sediment from the bottom of the tanker truck's tank, which can then get into your gas tank and potentially damage your car. This sediment is kicked up when new gas is pumped into the underground tanks at high speed, which can cause it to emulsify with contaminants. This can then pass into your tank and potentially damage your vehicle's fuel pump and carburettor/fuel injection system.
While modern gas stations have filters in their pumps that are meant to clean the gas before it reaches your vehicle, these filters do not remove all of the sediment. Additionally, the quality of the filters can vary depending on the age and location of the gas station. Older stations and those in rural areas with low traffic may have poorer-quality filters, increasing the risk of sediment contamination.
The risk of contamination is also higher if the underground tanks at the service station are old, as they are more likely to have accumulated contaminants over time. These tanks can let in muddy groundwater and microbial contaminants that promote algae and sludge, which can then be pumped into your vehicle along with the fuel.
If you suspect that your vehicle has been affected by contaminated fuel, there are a few things you can do to try and fix the issue. One option is to use a detergent-based fuel additive to help remove deposits from your injectors. Another option is to use a product like Fuel Doctor, which is designed to clean and disperse contaminants in fuel tanks.
In summary, while the risk of sediment contamination when refuelling from a tanker is relatively low, it is still a good practice to avoid doing so if possible. This is especially true if the gas station has older equipment or low traffic, as the quality of their filters may be poorer. By taking this precaution, you can help reduce the chances of potential damage to your vehicle's fuel system.

Use a product like Fuel Doctor to clean your tank
Fuel Doctor is a unique, industry-leading product that provides quality assurance for your fuel and protection for your entire fuel system. It is a fuel conditioner and injector cleaner that works on all diesel, petrol, and two-stroke engines, including cars, motorbikes, trucks, buses, boats, and mowers. It is also suitable for chainsaws, lawn care equipment, and jet skis.
Fuel Doctor was developed in 1994 as a 'tool of trade' for Fuel Doctors' industrial fuel tank cleaning operations. It is formulated to clean and disperse contaminants that settle at the bottom of the tank, such as gums, varnish, and sludge. The full chemical formulation of Fuel Doctor is a carefully guarded secret, but it contains detergent, dispersants, and lubricant as its four main components.
The detergent in Fuel Doctor helps clean and disperse gums and varnish that can build up in fuel systems. The two specific dispersants work to safely encapsulate moisture and fungal growths. These dispersants are composed of oxygenated molecules that pass into the combustion cycle, enhancing thermal efficiency and reducing soot, leading to cleaner and longer DPF serviceability.
The lubricant in Fuel Doctor ensures that any suspended sub-micron rust contaminants passing through the injectors and fuel system do not negatively impact any fuel system components. Additionally, Fuel Doctor acts as a fuel stabilizer, extending the life of stored petrol and diesel. It can stabilize petrol for up to 24 months and diesel for up to 60 months, depending on the source.
If you are experiencing issues such as poor fuel economy, rough idling, noisy injectors, premature fuel filter changes, or reduced power, these could be symptoms of contaminated fuel. In such cases, using a product like Fuel Doctor can help clean your fuel tank and improve your vehicle's performance.

Check for debris and contamination
It is important to check for debris and contamination in your fuel tank. Most fuel has some level of contamination from the moment it leaves the refinery. Even if the fuel in your tank is perfect, additional contamination is generated by the fuel system itself. Wear particles are created by mechanical friction. High heat and extreme pressure generated inside the modern engine lead to coking and the creation of carbon products at the injector. Much of this internally produced particulate is returned to the fuel tank along with the unburned diesel.
The most common types of fuel tank contamination come from water, particulates, and other fuel. Water contamination occurs due to vapour or the passing of time. A simple test can show whether or not fuel has been contaminated by water. Industry-standard should show no more than 30 parts per million of water present in the fuel. Particulates are due to rust, dust, pollen, or other airborne contaminants that can enter the fuel tank when open or if sealed improperly. Pipelines, barges, rail cars, and terminal tanks can also contribute to fuel contamination.
To check for debris and contamination in your fuel tank, you can test samples from the bottom, middle, and top to determine the presence of dirt, water, or other contaminants. Most particulates can be seen with the naked eye and will float or settle to the bottom of the fuel tank. If you suspect that you have contaminated fuel, your first priority is to take your car to your local mechanic or servicing dealer for a check and verification. If you are unable to drive your car, you can contact a roadside assistance team for help.
If you have contaminated fuel, it should be disposed of following industry standards and guidelines, and uncontaminated fuel should replace it. The cost of doing this can vary depending on the scale of the contamination. However, if contamination is left untreated, it can ruin vehicles and equipment.

Drain and clean your tank
If you have dirty fuel in your car, it's important to address the issue promptly to prevent damage to your engine and maintain optimal performance. One effective approach is to drain and clean your fuel tank, following these steps:
Prepare for the task:
Prioritize safety by working in a well-ventilated area, away from any open flames or sources of ignition. Put on protective gear, including gloves, safety goggles, and a face mask, to shield yourself from fuel splashes and fumes. Locate the fuel tank, which is typically at the rear of the vehicle but may be under the hood, and refer to your vehicle's manual for specific instructions.
Drain the fuel tank:
Start by removing the fuel tank cap to allow air to enter and facilitate draining. If your vehicle has an electric fuel pump, locate the fuel pump fuse or relay in the fuse box, remove it, turn on the ignition (without starting the engine), and let the fuel pump activate to drain the tank. Alternatively, use gravity by positioning your vehicle on a lift or jack stands, locating the fuel tank drain plug, and removing it to let the fuel flow into a container below. Remember to dispose of the drained fuel properly at a hazardous waste disposal site or recycling centre.
Clean the fuel tank:
Once the tank is empty, you can manually clean it. Compressed air and a lint-free cloth can be used to dry and wipe the tank. Inspect the tank for any damage, and if it's intact, ensure it's completely dry before refilling with fresh fuel. This process helps prevent contaminants from entering your new fuel.
Prevent future contamination:
To minimize the impact of dirty fuel, avoid refuelling when a tanker is filling the underground tanks at a service station, as this can stir up contaminants. Additionally, consider using a product like Fuel Doctor, which has been designed to clean and disperse contaminants in fuel tanks.
Address any underlying issues:
Dirty fuel can be caused by various factors, such as old fuel, microbial growth, water absorption, or rust. If your fuel issues are due to stale fuel, you may need to flush your entire fuel system and refill with fresh fuel. If microbial growth is a concern, look for cleaning solutions designed to address this issue, such as Delphi Technologies' fuel tank cleaning kit.
By following these steps and staying vigilant about fuel contamination, you can help keep your car's fuel system clean and maintain the performance and longevity of your vehicle.

Get your car scanned for trouble codes
Modern vehicles are equipped with internal computers that monitor the performance of your car, truck, or SUV. These computers also alert you to a problem by generating trouble codes. The on-board computer diagnostic system, or OBD, may alert you to problems with your vehicle's engine, airbags, antilock brakes, and other components. If your vehicle has this system, you will need an OBD-II diagnostic scanner to communicate with its OBD system. The diagnostic trouble code is the code your OBD generates to tell you something is wrong.
Some car parts stores have a "Diagnostic Scan Tool Code Reader for Check Engine Light" that they will let you use for free if you buy the parts there. In some states, it is illegal to scan codes if you don't have a mechanic on hand to diagnose and fix the issue. You can also purchase your own OBD II reader, which can range in price from $15 to $40. These readers are easy to use and can help you figure out what is wrong and clear the code to shut off the light. They read all the codes, not just the ones associated with the Check Engine light.
If you are experiencing issues with your vehicle, getting your car scanned for trouble codes is a good first step to take. This will allow you to identify any problems and take the necessary steps to resolve them. By using a diagnostic scan tool, you can access the trouble codes generated by your vehicle's on-board computer system and gain valuable insights into the health of your car.
It is important to note that while the scan tool can provide you with the trouble codes, you may need additional resources or expertise to interpret the codes and determine the appropriate course of action. Understanding the meaning of each code and the recommended fixes will help you address any issues effectively. Online resources and automotive forums can be helpful in deciphering the codes and finding solutions. Additionally, consulting a trusted mechanic can provide you with expert advice and guidance tailored to your specific vehicle and situation.
