The service stations always charge what it will take to refill their tanks...the gas in their tanks may have been lower but to refill them will cost them more... thats where the up price comes from...

[Young Werther]

Federal tax is included in the wholesale price of gas. state and local taxes are collected by the retail outlet. when a retail price change occurrs the state and local taxing authorities reap additional revenues along with the retail outlet.

Meanwhile the wolesale price is didctated by the COGs paid at the well head. which does not change as quickly as the specualtors actions.
