When is the Best Time to Refuel?
3 Answers
You should refuel before the fuel warning light comes on, which not only reduces damage to the fuel pump but also ensures fuel efficiency. Reasons for refueling before the fuel warning light comes on: Try not to wait until the fuel warning light comes on to refuel. This is because the fuel pump is located inside the fuel tank, and it generates high temperatures during continuous operation. Being submerged in fuel helps effectively cool it down. Hazards of refueling only after the fuel warning light comes on: When the fuel warning light comes on, it indicates that the fuel level is already below the fuel pump. If you consistently wait until the light comes on to refuel, it will shorten the lifespan of the fuel pump. Having too little fuel or running out of fuel can even burn out the fuel pump. Extra caution is needed if the vehicle has been driven over 30,000 kilometers.
Actually, I've been driving for over a decade, and safety is my top priority. When it comes to refueling, you should never wait until the fuel warning light comes on. At that point, there's too little fuel in the tank, which can cause issues with the fuel pump's heat dissipation. I make it a habit to refuel when there's about a quarter tank left. This protects the fuel pump and prevents sudden fuel depletion on the road. Last time, a friend's car broke down halfway because there was too little fuel, allowing impurities to enter the fuel line, costing hundreds in repairs. With fuel prices fluctuating these days, I always check for discount periods on my phone app before heading to the gas station. I fill up until the pump automatically stops—overfilling wastes fuel and increases the risk of spillage.
As a commuter, I usually refuel based on the fuel gauge and convenience. When the fuel level drops to a quarter, I'll top up a bit when passing by a gas station during weekend grocery runs. I don't wait for the warning light because rushing to refuel often leads to being overcharged. I've calculated that adding 200 yuan each time is just right—it doesn't tie up too much cash in the tank and lasts until the next discount day. I've heard that keeping the tank too low for long periods can damage the fuel pump, so I try to maintain at least half a tank. This way, unexpected overtime or detours to drop off friends won't leave me anxious.
