Siphoning: use a hose to transfer fuel from the tank to a container
Siphoning fuel from your car can be a useful skill to have in emergencies, but it is important to note that it can be dangerous and is illegal in some areas. If done incorrectly, siphoning can also damage your vehicle. Therefore, it is crucial to exercise caution and follow proper safety procedures.
To siphon fuel from your car using a hose and a container, you will need a length of tubing that is long enough to reach from the gas tank to a container on the ground, as well as a pair of pliers and a container to hold the fuel. The fuel tank is usually located beneath the car, near the rear wheels. Place the container lower than the gas tank. Insert one end of the tubing into the gas tank through the fuel filler neck, ensuring that it is securely in place and reaches the bottom of the tank.
Once the tubing is in place, you can begin to siphon the fuel. If you are using a manual or electric siphon pump, follow the instructions provided with the pump. Another method of siphoning is using air pressure. This involves inserting one end of the siphon hose into the gas tank and the other end into the container, then using a small air compressor or bike pump to create pressure in the container. This pressure will force the gas out of the tank and into the container. Be cautious when using this method, as too much pressure can cause the gas tank to rupture or explode.
After you have finished siphoning, remove the tubing from the tank and allow any remaining fuel to drain into the container. Use the pliers to crimp the tubing and stop the flow of fuel. Finally, dispose of the fuel properly. Check with your local authorities for regulations on how to safely dispose of gasoline.

Using a professional service can also provide peace of mind, as they are experienced in dealing with fuel contamination. They will be able to assess the extent of the problem and take the necessary steps to resolve it. This can include not only draining the fuel tank but also cleaning the fuel lines and replacing any damaged components.
In some cases, attempting to remove bad fuel yourself can be dangerous, wasteful, and messy. It may also require specialised tools and knowledge of vehicle maintenance. By contrast, professional fuel drain services are equipped with the necessary tools and expertise to handle the job efficiently and effectively. They can also provide advice on preventing future incidents of fuel contamination and maintaining the health of your vehicle.
Overall, if you find yourself with contaminated fuel in your car, calling a professional fuel drain service is a quick and reliable solution. They will ensure that the job is done correctly and safely, minimising the risk of damage to your vehicle and getting you back on the road as soon as possible.

Burn it out: add a proper additive to your fuel tank to burn the bad gas
If you suspect that your car has bad gas, it is important to take action to prevent potential damage to your engine and fuel system. Bad gas refers to fuel that doesn't properly combust, leading to issues such as difficulty starting the engine, rough idling, and stalling. One way to deal with bad gas is to burn it out by adding a proper additive to your fuel tank.
When choosing a fuel additive, it is important to select one that is specifically designed to address the issues caused by bad gas. Look for additives that contain detergents, as these are formulated to clean the injectors, valves, and fuel pump, removing deposits and improving combustion. PIB detergents (polyisobutylene) and PEA polyether amine detergents are examples of effective detergent packages. Additionally, dry gas additives can help prevent moisture buildup and reduce the risk of rust in metal fuel tanks. However, it is important to consult a knowledgeable mechanic before using dry gas, as high amounts of alcohol can damage plastic or rubber components in the fuel system.
Octane boosters are another type of fuel additive that can be used to burn out bad gas. These additives are useful if your engine requires high-octane fuel but is currently running on lower-octane gas. By adding an octane booster, you can improve combustion and engine performance. However, if your engine is not tuned to take advantage of high-octane fuel, you may not see any benefits from using an octane booster.
When using any type of fuel additive, it is crucial to read up on the chemicals they contain and follow the instructions carefully. Adding the wrong substance to your fuel tank can lead to expensive repairs, so it is always best to consult a professional if you are unsure.
While burning out bad gas with additives is a viable option, it may not be effective in all cases. If the gas has undergone phase separation, it is highly unlikely that any additive will restore it to a usable state. In such cases, removing the bad gas and performing a detailed cleaning of the fuel system may be necessary.

Use a drain plug: if your car has one, this is an easy way to remove contaminated fuel
If your car has a drain plug, you can use it to remove contaminated fuel. This method is straightforward and does not require any specialised equipment. However, it is important to prioritise safety by disconnecting the negative battery terminals to prevent any issues with sparks and fires while draining the fuel.
To start, locate the drain plug. Typically, it is situated near the bottom of the fuel tank, on the same side of the car as the fuel door. Once located, place a large pan, basin, or another type of container underneath the drain plug to catch the fuel. Ensure the pan is directly under the plug as you will not be able to stop the flow of fuel once it starts.
Now, use a wrench or a spanner to loosen and unscrew the drain plug. As you do this, the fuel will begin to drain out. This process can take a while, with up to several minutes required per gallon of fuel. Keep an eye on the draining process and be prepared to catch the fuel in the container.
After all the fuel has been drained, replace and tighten the drain plug. It is important to note that even with the contaminated fuel removed, your vehicle may not return to its optimal condition. It is advisable to get your car assessed by a trusted mechanic to ensure there is no lasting damage to the engine.

Remove the tank: this is the most effective way to get rid of bad fuel, but it is labour-intensive and complicated
Removing the fuel tank is the most effective way to get rid of bad fuel without damaging your engine. However, it is a complicated and labour-intensive process. If you are not a trained mechanic, consider hiring a professional to do this for you.
To remove the tank, first, siphon the bad fuel out of the tank. Place one end of a hose into the gas tank and the other end into an empty fuel container. Ensure the container is placed lower than the gas tank. You can use your mouth to create suction and siphon the fuel. Once the fuel starts flowing, remove the hose from your mouth.
After removing the fuel, you will need to remove the fuel tank itself. This may involve releasing bolts and carefully lowering the tank to the ground. Once the tank is removed, you can flush it with water and clean it thoroughly. Ensure you also replace the fuel filter and clean the fuel pump and fuel lines to remove any contaminants.
Finally, you will need to reassemble everything. This process can be time-consuming, especially for beginners, so take your time and be careful.
