Why You Should Refuel When Your Gas Tank Is Half Full
Why You Should Refuel When Your Gas Tank Is Half Full — The Science-Backed Reason Most Drivers Don’t Know Many drivers wait until the warning light turns on before refueling. However, automotive engineers and maintenance experts agree on one thing: refueling at half tank is safer, smarter, and cheaper in the long run. 1. Fuel Pumps Are Cooled by Gasoline Inside most modern cars, the fuel pump is submerged in gasoline. This fuel acts as a coolant and lubricant . When the tank runs low, the pump is exposed to heat, increasing wear and failure risk. Refueling at half tank keeps the pump properly cooled, which can extend its lifespan and reduce repair costs . 2. Sediment and Impurities Stay at the Bottom Over time, small particles and sediment naturally collect at the bottom of the fuel tank. When fuel levels are very low, these particles are more likely to be sucked into the system. Keeping your tank above half reduces the chance of clogged fuel filt...
