While gasoline doesn't exactly go bad like food does, it does degrade over time. This degradation occurs due to oxidation and evaporation, which can cause operational issues in your car. These issues can include failure to start, a hesitant ignition, a rough-sounding idle, or loss of power while driving. The time it takes for gasoline to degrade depends on the fuel type, with regular gasoline lasting three to six months, premium or high-octane fuel lasting close to nine months, and diesel lasting up to a year. To prevent issues with your car, it's recommended to drive it a few times a week, even for short distances, and to keep the fuel tank filled to avoid moisture build-up and corrosion. Additionally, consider adding a fuel stabilizer to your tank, which can help fight fuel breakdown.

Fuel doesn't 'go bad' like food does, but it does degrade over time
Unlike food, fuel doesn't exactly "go bad". It doesn't have an expiry date after which it suddenly becomes unusable. However, it does degrade over time, and its chemical properties change. This degradation is influenced by environmental factors such as heat, oxygen, and humidity. The time it takes for fuel to degrade depends on how it is stored and its composition. For example, the amount of ethanol in the fuel can affect how long it lasts; ethanol can lose its combustibility in one to three months due to oxidation and evaporation. Similarly, diesel can last up to a year before it begins to degrade, while regular gasoline has a shelf life of three to six months, and premium or high-octane fuel can last close to nine months.
Fuel degradation can cause operational problems in vehicles, such as failure to start, hesitant ignition, rough-sounding idle, or loss of power while driving, especially when accelerating. The engine may not be able to process the fuel correctly due to the change in its chemical properties. Additionally, the fuel may have a darker or muddier appearance and a sour or disagreeable odour when it degrades.
To prevent fuel degradation, there are several measures that can be taken. One option is to add a fuel stabilizer, which fights fuel breakdown. Filling the tank can also help, as it prevents air and water from accessing the tank and causing corrosion or moisture build-up. Driving the vehicle regularly, even for short distances, can also help keep the fuel fresh.
While fuel does degrade over time, it is important to note that it is not as perishable as food. It can last for months to years, depending on the type of fuel and storage conditions. However, taking proactive measures to maintain the fuel can help extend its usability and prevent potential vehicle issues.

Modern cars are sealed to prevent fuel vapour from escaping into the atmosphere
Modern cars are designed to prevent fuel vapour from escaping into the atmosphere. This is achieved through the use of sealed fuel systems and evaporative emission control systems (EVAP).
Firstly, the fuel systems in modern cars are sealed by legislation to prevent evaporative emissions. This means that fuel vapour, which is lighter and therefore evaporates first, cannot escape from the fuel tank into the atmosphere. This is in contrast to older vehicles, where gasoline fumes would evaporate and be vented directly into the atmosphere.
Secondly, modern cars are equipped with an EVAP system, which is designed to capture and store fuel vapours, preventing their release into the atmosphere. The EVAP system includes components such as a fuel tank, canister, purge valve, and sensors. When fuel vapours form in the sealed fuel tank, they are captured and transferred to the EVAP canister, which contains activated charcoal that absorbs and stores the vapours. Once the engine is started, the vapours are then drawn into the combustion chamber, where they are burned along with the liquid fuel. This process helps to reduce air pollution by minimising the release of vaporised hydrocarbons, which contribute to the formation of photochemical smog and ground-level ozone.
Additionally, modern cars have other features that help prevent fuel-related issues. For example, the fuel pump is typically located inside the tank, which helps prevent vapor lock, a problem caused by liquid fuel changing state to vapour in the fuel delivery system. Modern engines are also equipped with computer-controlled fuel injection systems, which ensure more precise air-fuel mixtures, improving combustion efficiency and reducing pollutant generation.
While modern cars are designed to prevent fuel vapour escape, it is important to note that fuel degradation can still occur over time. This can be influenced by factors such as the type of fuel, storage conditions, and the presence of stabilisers. Regular maintenance and following storage guidelines can help mitigate these issues and ensure optimal vehicle performance.

Engines shut off when they can't suck any more fuel, to prevent damage
Modern start-stop technology detects when a vehicle is stationary, out of gear, or running in low-load conditions, and automatically shuts off the engine to reduce fuel consumption and emissions. This is because modern fuel injection engines use more fuel when idling than when shutting off and restarting. While start-stop systems may not save you much money on fuel, they are much more pleasant for pedestrians walking alongside a traffic queue.
When a car runs out of gas, it doesn't usually result in the engine suddenly stopping. Instead, fuel flow becomes weak, air gets into the system, and the car eventually comes to a stop. This can be dangerous, as it may cause the driver to lose control of the vehicle. Additionally, fuel pumps need fuel flowing through them to stay cool, and without this flow, the pump's electric motor could burn out and require replacement.
While fuel doesn't exactly "go bad" like fresh food, it does degrade gradually over time. The length of time fuel remains usable depends on the fuel type. Regular gasoline has a shelf life of three to six months, while premium or high-octane fuel can last up to nine months. Diesel can last up to a year, and organic-based ethanol can lose its combustibility in one to three months due to oxidation and evaporation.
To prevent fuel degradation, it is recommended to drive the vehicle regularly, add a fuel stabilizer, and keep the fuel tank filled to avoid moisture build-up. By taking these proactive measures, drivers can help ensure that their vehicles run smoothly and avoid costly repairs.

Indicators of bad fuel include the ''check engine' light, operational problems, and changes in appearance and smell
The fuel system is one of the most important systems in your car, as it supplies the engine with fuel to operate efficiently. If the fuel system is starting to fail, various symptoms may appear, impacting the car's performance, fuel economy, and safety. One of the first indicators of bad fuel is the "check engine" light coming on. Modern cars have sensors that monitor the fuel system's performance, and the check engine light illuminates when it detects a problem. If the light stays on or blinks, it indicates a persistent issue that requires attention. Another sign of a failing fuel system is a strong fuel smell inside or outside the car, which could indicate a leakage in the fuel lines or tank. These leaks are dangerous and should be addressed immediately.
Operational problems are another indicator of bad fuel. Your car may experience difficulty starting, a hesitant or rough-sounding ignition, loss of power while driving, especially during acceleration, or stalling while driving. These issues could mean that the engine is not getting enough fuel for ignition due to a non-functional fuel pump or a blocked fuel filter.
Changes in the appearance and smell of the fuel can also indicate that it has gone bad. Bad fuel will have a darker or muddier look and a sour or disagreeable odour not typical of normal fuel. Some may even describe the smell as spoiled. The shelf life of fuel depends on its type: regular gasoline lasts three to six months, premium or high-octane fuel lasts about nine months, diesel can last up to a year, and organic-based ethanol can lose its combustibility in one to three months.
To prevent fuel-related issues, it is recommended to use quality fuel, regularly check the fuel system, and consult professional mechanics when problems arise. Additionally, driving the vehicle a few times a week, even for short distances, and keeping the fuel tank filled can help maintain fuel quality and avoid moisture build-up.

Fuel stabilizers can be used to prevent fuel breakdown
Fuel does not "go bad" like food does. However, it does degrade over time, and fuel stabilizers can be used to prevent this breakdown. Fuel stabilizers are designed to maintain the quality of stored fuel and extend its lifespan. They are particularly useful for seasonal equipment, classic cars, or boats that tend to sit for more than three weeks at a time.
Fuel stabilizers work by creating a protective layer over the fuel, preventing evaporation and oxidation. They are typically made from petroleum products and contain antioxidants and lubricants designed to repel water and limit evaporation. This helps to prevent the formation of sticky resins that can ruin a carburetor and cause engine problems.
When using a fuel stabilizer, it is important to follow the product instructions and ensure that your vehicle's gas tank is nearly empty. Then, measure the correct amount of stabilizer and pour it into the tank. Run the engine for at least 5-10 minutes to allow the stabilizer to reach the entire fuel system.
There are several fuel stabilizers on the market that offer long-term storage and protection. For example, Berryman Total Fuel Stabilizer is compatible with all 2-stroke and 4-stroke engines and can be used for the long-term storage of all grades of gasoline and diesel fuel. Sta-Bil is another popular option that offers year-round protection and keeps gasoline fresh for up to 24 months. It is safe for all gasoline-powered vehicles, including motorcycles, ATVs, and watercraft.
In summary, fuel stabilizers are an effective way to prevent fuel breakdown and maintain the quality of stored fuel. They can help prevent engine problems and keep vehicles running smoothly, especially when stored for prolonged periods.

Frequently asked questions
When your car's fuel goes to E, it means that your tank is almost empty. This is your car's final warning that it is low on fuel.
There is no standardised amount, but independent estimates suggest that the fuel light comes on when there is 10% to 15% of fuel left in the tank.
When your car's fuel goes to E, make plans to get to the nearest garage as soon as possible. Once a car hits a quarter tank, get it filled up to avoid all potential issues.
If you continue driving when your car's fuel goes to E, your car will eventually run out of gas and turn off. Your car may also start to stutter and splutter as the fuel pump fails to feed the engine, and you may hear noises as your car picks up debris from the bottom of the tank.
