What You'll Learn
Avoid water, bleach, and sugary drinks
Water, bleach, and sugary drinks are among the worst things you can put in your fuel tank. Here's why you should avoid them:
Water
Water is one of the most harmful substances you can put in your fuel tank. While a small amount of moisture or condensation may find its way into your tank naturally, a significant amount of water will sink to the bottom of the tank and prevent the fuel from combusting. This will cause the engine to stop working. While it is possible to chemically treat the water and revive the engine, it is best to avoid this issue altogether by ensuring no water enters the fuel tank.
Bleach
Bleach is mostly water, but it also contains a small amount of chlorine, which makes it caustic and corrosive. When bleach is introduced to a fuel tank, the chlorine will pre-burn into the fuel before it reaches the engine. As a result, the car will run for a short period before coming to a stop with the liquid mix jetting out of the fuel injectors and other components of the fuel system. Driving with bleach in the tank for an extended period will result in disastrous effects, as the bleach will erode the rubber and metal parts of the fuel lines, tank, pump injectors, cylinder head, and intake manifold. Therefore, it is crucial to avoid putting bleach in your fuel tank and to seek professional help if you suspect your tank has been contaminated.
Sugary Drinks
Contrary to popular belief, pouring sugar into your fuel tank will not disable your car. Sugar does not dissolve in gasoline but instead sinks to the bottom of the tank. While it may cause some annoyance by creating a sludge at the bottom of the tank, it will not damage the engine. Modern fuel filters are designed to catch impurities like sugar crystals, preventing them from reaching and damaging the engine. So, while sugary drinks may not be the best thing to put in your fuel tank, they are unlikely to cause significant harm.

Choose the right pump
Choosing the right pump is essential to ensure your vehicle receives the correct type of fuel and to prevent potential damage to your engine. Here are some detailed instructions to help you select the right pump:
Firstly, it is crucial to identify the type of fuel your vehicle requires. Consult your vehicle's owner's manual to determine the specified fuel grade. Most standard U.S. gas stations offer three different fuel grades: 87, 89, or 93 octanes. Using the wrong fuel grade can potentially cause engine damage.
Once you know the required fuel grade, carefully approach the gas station pumps. Pay close attention as some pumps dispense only diesel fuel, some dispense only regular gasoline, and some may offer both through separate nozzles. Ensure that you select a pump that provides the type of fuel your vehicle needs.
When you have identified the correct pump, position your vehicle carefully. Pull up as close as possible to the pump while maintaining a safe distance of about 2 to 3 feet for easy navigation between your car and the pump. Once in position, put your car in park or neutral if it has a manual transmission, and turn off the ignition.
If it is a hot day and you have children or pets in the car, remember to roll down the windows to allow air circulation. Always leave flammable objects like lighters and electronic devices inside the vehicle while refueling to avoid any potential ignition of gas fumes.
By following these steps and choosing the right pump, you can safely and effectively refuel your vehicle, ensuring the correct fuel type and maintaining the optimal performance of your engine.

Leave enough space between car and pump
Leaving enough space between your car and the pump while turning is crucial for safety. Here are some detailed instructions and reasons to emphasise the importance of maintaining adequate space:
Firstly, when pulling up to the pump, it is essential to strike a balance between getting as close as possible and leaving sufficient space for manoeuvring. Aim for a distance of about 2 to 3 feet between your car and the pump. This space is crucial for your safety and that of others. It allows you to navigate and move around your vehicle without obstruction. This is especially important if you need to quickly exit your car in an emergency.
Secondly, maintaining a safe distance between your car and the pump is vital to mitigate the risk of fires and explosions. While it may seem harmless, static electricity can sometimes be generated when exiting your vehicle, potentially igniting gasoline vapours. By leaving enough space, you reduce the chances of this happening. Additionally, open flames, such as cigarettes and lighters, have been known to ignite gas fumes, so it's best to leave them in the car.
Furthermore, keeping a safe distance between your car and the pump improves overall safety and visibility. It allows you to be aware of your surroundings, including other vehicles, pedestrians, and potential obstacles. This awareness can help you avoid collisions and manoeuvre more efficiently. It is also essential to be mindful of other drivers' blind spots and avoid driving directly alongside them. Maintaining a safe distance from parked vehicles is also crucial for safety and ease of movement.
Additionally, leaving enough space between your car and the pump can help prevent damage to your vehicle. When turning, it is essential to be cautious and avoid colliding with the pump or other objects nearby. Striking the pump or another vehicle could cause scratches, dents, or more severe damage. Therefore, it is always best to leave yourself enough room to turn safely.
Lastly, by leaving enough space, you make it easier to access your fuel tank and insert the nozzle correctly. This might seem like a minor detail, but it can help prevent spills and overflows. When you have sufficient space to work with, you can carefully and accurately remove the nozzle from the gas tank and point it away from you as you turn it back to the pump. This careful handling will help keep you and your vehicle clean and free from gasoline spills.

Turn off ignition
Turning off the ignition while fuelling a car is a safety precaution that should not be overlooked. While some may argue that the chances of accidents are slim, it is always better to take precautions to ensure your safety and that of others.
Firstly, gasoline has a high ignitability, meaning it can easily burn. When an engine is running, there are multiple possible sources of ignition, including the alternator or electric motor contact arcing. In older vehicles, distributors could even trigger flash fires or explosions. Therefore, a running engine adds an ignition source to an environment that already contains fuel vapours, creating the potential for a fire triangle—a combination of fuel vapour, oxygen, and sources of ignition.
Secondly, turning off the ignition can help prevent accidents caused by driver error. In a hurry or distracted, drivers may accidentally move their cars during refuelling, leading to fuel spills and potential fires. Additionally, leaving the engine running may increase the chance of driving away with the fuel hose still attached, which could result in a dangerous situation.
Furthermore, static electricity can be a concern when entering and exiting the vehicle during refuelling. Sliding over seats can create static electricity, which can then be transferred to the metal fuel nozzle, resulting in a spark that could cause an explosion. While the risk of fire from static electricity may be low, it is still a possibility that should be avoided by turning off the ignition and the vehicle before refuelling.
Finally, turning off the ignition allows you to be physically and psychologically present during the refuelling process. By staying with your vehicle, you can monitor for any issues, such as the smell of gas, and address them immediately. This proactive approach helps to identify and mitigate potential hazards, ensuring a safer refuelling experience.
In conclusion, turning off the ignition while fuelling a vehicle is a crucial safety measure. By doing so, you reduce the risk of fires, accidents, and hazardous situations. While some may argue that the chances of an accident are low, it is always better to prioritise safety by taking preventive actions.

Clean fuel system regularly
Keeping your fuel system clean is an important part of vehicle maintenance. While it's not essential, it is good practice to clean your fuel system regularly. This is because deposits from the combustion process, dirt and debris from pump nozzles and filler caps, and general wear and tear can all cause a build-up of grime. This can lead to clogged injectors, which means inefficient combustion and increased strain on the engine, jeopardising its long-term performance.
A fuel tank treatment involves pouring a mixture of cleansers, stabilizers, lubricants, or performance boosters into the gas tank. The purpose of the treatment is to help the engine run smoothly, preserve fuel quality, and prevent engine damage. There are a variety of diesel tank treatments available, including cleaning, lubrication, performance boosts, stabilization, and moisture control.
To clean your fuel system, you can add a cleaner directly to your fuel tank. This will move through the fuel system and remove deposits from fuel injectors, leading to better performance and reduced emissions. You can also clean the gas pump, fuel lines, and fuel injectors by adding cleaner to the fuel tank and letting the engine run.
There are a number of chemical cleaner options for cleaning fuel tanks, including Rust Remover by Evapo-Rust, Fuel System Cleaner by Star Tron, and Fuel Tank Cleaner by Red Line. It is also important to regularly inspect your fuel tank for any signs of contamination or build-up, and to keep the exterior clean and clear of debris.
It is recommended that vehicles undergo fuel system cleaning every 60,000 to 90,000 miles, though some experts recommend every 30,000 miles.
