Will the oil in a car evaporate?

[McMolly]

Evaporation is minimal as the fuel tank cap is sealed with a rubber gasket, and the fuel lines connected to the engine are also sealed. For gasoline, more details are as follows: Gasoline evaporation: It will not evaporate from the fuel tank, but gasoline left for a long time may deteriorate, potentially producing excessive gum and carbon deposits in the intake system, affecting the engine's normal operation. Gasoline is a highly volatile industrial oil product, but the gasoline added to a car's fuel tank is generally well-sealed and not prone to evaporation. If the fuel tank's sealing is poor, it may evaporate to some extent. During summer when temperatures are higher, it is advisable not to leave the car exposed to direct sunlight, as this can cause minor evaporation and slight damage to the gasoline lines.
