When should you refuel based on the fuel gauge?

The pointer at a quarter of the fuel gauge indicates it's time to refuel. This is to protect the fuel pump, as most modern cars use electric fuel pumps and electronic fuel level sensors that need to be immersed in gasoline for cooling. If the gasoline level is too low, the fuel pump won't be submerged, significantly affecting its cooling efficiency. Poor cooling can shorten the fuel pump's lifespan or even cause it to burn out. Here is an introduction to engine oil: 1. Engine oil is the lubricant used in engines. It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks. Known as the "blood" of a car, it consists of base oil and additives. 2. Base oil is the main component of lubricants, determining their basic properties, while additives compensate for and improve the shortcomings of the base oil, providing certain new characteristics, making them an essential part of lubricants.
I always refuel when the fuel gauge shows a quarter tank left, as with over 20 years of driving experience, I know running too low on gas can lead to trouble. Once, a friend ran out of fuel on the highway, nearly causing an accident, and the repairs cost over a thousand dollars. Low fuel levels can overheat and damage the fuel pump, and may also draw in impurities from the bottom of the tank, clogging the fuel system, which results in high repair costs. Keeping a quarter tank avoids these risks and ensures preparedness for traffic jams or areas with few gas stations. I’ve developed a weekly fuel-check habit and always fill up before long trips. This practice enhances vehicle longevity and safety. Refueling early also helps avoid peak hours, saving both time and money.
