Your vehicle’s fuel tank does more than just hold petrol/diesel, it plays a key role in your car’s performance, fuel efficiency, and engine health. Yet, many drivers overlook how important it is to maintain it properly. From avoiding overfilling to preventing rust and protecting your fuel pump, these simple fuel tank care tips can help you save money, reduce breakdowns, and keep your car running smoothly for years to come.
1. Avoid Overfilling: Overfilling your fuel tank can cause serious problems with your car’s evaporative emission system (EVAP). Think of the EVAP as your car’s breathalyzer, ensuring that harmful petrol vapours don’t escape into the atmosphere. Overfilling can disrupt this system, leading to engine issues and increased fuel consumption.
2. Know Your Range: Once your fuel light comes on, you can typically drive another 5-10% of the total tank capacity. However, this is just an estimate and can vary depending on your driving style, road conditions, and vehicle load. It’s like having a secret reserve of petrol in your tank
3. Detecting EVAP System Issues:
If you hear a hissing sound or see air bubbles coming out of your fuel cap when you open it, it could be a sign that your EVAP system is having trouble. This is like your car’s breath smelling a bit off. A mechanic can diagnose and fix the issue.
4. Understanding Fuel Tank Capacity:
Your car’s owner’s manual will provide an estimated fuel tank capacity. However, this is just an estimate and can vary slightly. Factors such as the specific model, trim level, and options can influence the tank size.
5. The Perishability of Fuel:
Petrol, like many other products, has a limited shelf life. Regular petrol typically lasts 3-6 months, while diesel can last up to a year. However, storage conditions and fuel additives can affect these estimates. If you’re storing your car for an extended period, it’s a good idea to use up the remaining fuel or add a fuel stabilizer.
6. Preventing Rust and Moisture:
Keeping your fuel tank at least half full can help prevent rust and moisture from accumulating inside. Rust can clog fuel lines and injectors, while moisture can lead to fuel contamination and performance issues. This is especially important if you’re storing your car for or during a long trip.
7. Protecting Your Fuel Pump:
Your electric fuel pump relies on petrol to stay cool. When the petrol level drops too low, the pump can overheat, which can reduce its lifespan and lead to premature failure. It’s best to avoid running your tank very low, especially on long trips.
8. Dispelling Myths About Fuel Tanks:
Contrary to popular belief, a full fuel tank will not explode, even in extreme heat. Fuel tanks are designed to withstand high temperatures and pressures. However, it’s still important to avoid overfilling, as this can increase the risk of fuel vapors escaping and potentially igniting.
By following these guidelines, you can help ensure the optimal performance and longevity of your vehicle’s fuel system. Happy driving
