That is my point exactly, and well said.
It's correct, and it makes sense. This is not about the fuel being stored in underground tanks where (I agree) the temperature in the ground is relatively stable. It's about what happens after the gasoline is pumped into the hot fuel tank of your car, that becomes even hotter yet, as the temperature of the day becomes hotter.
