When is the Best Time to Refuel?

[Olive]

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.

Based on my years of maintenance experience, refueling frequency should align with driving habits. For someone like me who mainly drives in the city, it's best to refuel when the fuel gauge reaches a quarter. Driving with low fuel levels for extended periods can allow sediment at the bottom of the tank to enter the fuel system. Moreover, during the hot summer months, having too little fuel leads to faster gasoline evaporation and affects heat dissipation. I usually refuel on Wednesday mornings on my way, avoiding weekend rushes and taking advantage of gas station discounts. Long trips are a different story—I always fill up at major gas stations along the way beforehand, as I don't trust the fuel quality at smaller stations.

I often drive my kids to school, so I have to plan my refueling in advance. Once, I only started looking for a gas station when the fuel light came on, and ended up stuck in a long queue near the school, almost making us late. Now, every Wednesday after dropping off the kids, I pull into my regular gas station when there are still two bars left on the fuel gauge. Using my membership card saves me 0.2 yuan per liter, which adds up to a cup of milk tea money in a month. I dread running low on fuel during emergencies, so I always keep at least half a tank. After refueling, I check the tire pressure and wipe the windshield—the whole process takes about fifteen minutes, much better than breaking down on the road.

Actually, the refueling rhythm is directly related to driving habits. I frequently drive on highways and am accustomed to using cruise control, refueling when the fuel gauge reaches one-quarter to avoid emergencies. I specifically tested the fuel tank capacity and found that refueling when there's 50 km of range left is the most economical, as the gasoline weight is lightest and doesn't affect fuel consumption. Once, I waited until the fuel light came on and got stuck on the highway for two hours, so now I never take that risk. I also refer to the fuel consumption data calculated by the onboard system—if there's been a lot of sudden acceleration recently, I refuel earlier, but with smooth driving, I can delay it appropriately.
