As the saying goes, "Thermal expansion". In summer, refueling is a good choice when the temperature is low, as the density of the car is high and refueling is more economical.
1. When refueling, ask the oiler to slow down a bit, which can add 3% -5% more fuel.
2. After refueling, lock the fuel tank cap to reduce oil evaporation loss and keep the oil clean.
3. As the temperature is too high in summer, the gasoline in the fuel tank is easy to evaporate. If the driver usually drives in the urban area, it is unnecessary to fill the fuel tank too full. It is usually enough to reach about 70% of the fuel tank capacity. Adding 70% or 80% of the full fuel will not only reduce the gasoline volatility, but also save some load capacity for the compressed Garbage truck, which is good for fuel saving.
