How Many Kilometers Can an Auxiliary Fuel Tank Drive?
2 Answers
Different models and brands vary. For example, Toyota's auxiliary fuel tank, based on its original design as a reserve fuel supply, should theoretically allow driving for about 100 kilometers. However, considering actual road conditions and individual driving skills, it's safer to estimate roughly 50-70 kilometers before refueling promptly. Below is a detailed introduction to switching from the main tank to the auxiliary tank: 1. Conventional Vehicle Operation: The main/auxiliary tank switch button is usually marked with a "SUB+fuel pump" symbol. Pressing it will switch the vehicle to the auxiliary tank, and fuel supply will then come from the auxiliary tank. 2. Some Truck Operations: For certain trucks, the main/auxiliary tank switch button is labeled "AUXILIARY-FUEL-TANK." Pressing this button will activate fuel supply from the auxiliary tank.
After installing an auxiliary fuel tank in my car, long-distance driving has become much easier. In the city, the fuel consumption is around 10L/100km, and the auxiliary tank has a capacity of about 20 liters, theoretically extending the range by 200km. However, in practice, on highways with good road conditions, it can indeed cover nearly 200km. When off-roading in mountainous areas with rough terrain and higher fuel consumption, the range might drop to around 150km. It also depends on driving habits—gentle acceleration and steady throttle control can extend the range a bit. Over the past few months, I've found it most suitable for long trips, especially in remote areas with fewer gas stations. Having extra fuel provides peace of mind. When installing, choose a reputable brand and regularly check the seals to prevent leaks, which can damage the car and pose safety risks. Remember, an auxiliary tank isn't an infinite fuel source—don’t rely on it too much. It’s safer to switch to the auxiliary tank only when the main tank is nearly empty. In summary, the range provided by an auxiliary tank depends on its size, your car’s fuel efficiency, and road conditions. Use it flexibly.
