Does gasoline expand and contract significantly with temperature changes?

[StJayla]

Gasoline does not expand and contract significantly with temperature changes. Here are the relevant details: 1. Basic knowledge: Gasoline has a much lower density than water, so one liter of gasoline weighs less than one kilogram. At room temperature (25°C), taking 93-octane gasoline as an example, its density is approximately 0.725 kg/L, meaning one liter of gasoline weighs around 0.7 kg—still far from one kilogram. When the temperature rises, its volume increases, and consequently, its density decreases slightly. From this perspective, the thermal expansion and contraction of gasoline do affect its density to some extent, though the change is minimal. 2. Thermal expansion of gasoline: Gasoline does expand and contract with temperature changes. For every 1°C increase in temperature, the volume of gasoline expands by approximately 0.12%.
