What are some money-saving methods for refueling cars?

[Elsa]

Introduction to money-saving methods for car refueling: 1. Try to avoid refueling during midday when the sun is intense and temperatures are high. Fuel is charged by volume rather than weight, and volume is affected by temperature due to thermal expansion and contraction. Refueling in the morning or evening allows the same volume of gasoline to have more mass, naturally saving some cost by choosing cooler times. 2. Avoid refueling by specifying a fixed amount of money. This method often leads to rounding off by the fuel pump, which can result in unnoticed financial losses. 3. Avoid filling the tank completely when driving in the city. City driving often involves frequent stops and starts, and a full tank adds extra load to the engine, reducing acceleration and increasing fuel consumption. 4. Do not refuel while the gas station is receiving a fuel delivery. When a fuel tanker arrives to refill the station's storage, it can stir up sediment from the bottom of the tanks. If this sediment enters the engine, it can affect the engine's lifespan. 5. Choose reputable gas stations for refueling. Opting for suspiciously low-priced gasoline is not a sustainable solution. If your vehicle suffers damage due to poor fuel quality, regret will come too late.
