How Much Fuel Should You Add at a Time?
2 Answers
It is generally recommended to fill the fuel tank to about 60% to 70% of its capacity. This not only reduces the vehicle's weight but also avoids the potential hazards of a full tank. Below are some relevant tips for refueling your car: 1. Engage the handbrake: Some gas stations are located on slopes, so always remember to engage the handbrake while refueling to prevent the car from rolling backward and causing an accident. 2. No smoking: Do not use lighters or any other ignition tools at gas stations, as the area is filled with flammable gas molecules, and even the smallest spark can lead to a fire or explosion.
Having driven for over a decade, I believe it's best to stop refueling when the pump automatically clicks off, rather than forcing the tank to be completely full. Leaving some space in the fuel tank prevents fuel from sloshing out, which could pose safety risks or damage components. On the other hand, refueling too little means frequent trips to the gas station, wasting time and increasing cost per kilometer due to extra travel expenses. A moderate fill level keeps the fuel pump submerged in gasoline, extending its lifespan and preventing overheating issues. My habit for city driving is to refuel once a week—enough to cover usage while balancing the budget. For long trips, I fill up completely to avoid unnecessary stops along the way. Overall, adjustments should be made based on the vehicle model and trip specifics—it's not a one-size-fits-all approach. Learning basic maintenance knowledge benefits every driver.
