Is it true that I get more bang for the buck if I fill up my tank at night? The argument is that matter expands when it's heated; so during the night, I get more volume of petrol for the same price? I know the difference is miniscule, but is the argument true?

Gas (petrol) question: We've had discussions in the blue about regional price differences for gasoline. But why do different gas stations in the same market region come so close to each other on price? Are the markets for the raw oil and the refining so limited that they all end up with the same cost? I find that hard to believe. Also, is there any difference, in real terms, between gasoline from one vendor versus gas from another?
