Should I refuel when there are two bars of gas left in the car?

You should refuel when there are two bars of gas left in the car. Here are some precautions regarding car refueling: 1. Avoid refueling when the tank is empty: It's best not to wait until the fuel tank is completely empty before refueling, as the fuel pump is immersed in the tank, and running it too low can affect its cooling and heat dissipation. 2. Try not to overfill the tank: Unless you're going on a long trip, it's not necessary to fill the tank to the brim. Gas stations are widely available now, and filling up to two-thirds of the tank is usually sufficient, allowing you to drive over 300 kilometers. 3. Refuel when the tank is one-quarter full: It's best to refuel when the fuel tank has about one-quarter of its capacity left. This ensures you have enough fuel to find a gas station, and even if the station is far away, you won't have to worry about running out of gas on the way and getting stranded.
