No gas May 15th will not work. Only thing accomplished will be an easy day for owner/operators. Example: Normal day consumption average per car is 3 gallons. End of day on May 16, vehicle will need 6 more gallons to top off their tanks. Resulting in no loss of consumption for big oil/gas.

Boycotting 2 selected brands, say Exxon and Shell will not have an affect also. They will end up selling their product to remaining brand staitions still selling to make up for the laws of supply and demand. We don't buy Exxon or Shell, we have to buy gas somewhere else right? Again only persons taking it on the chin are the owner/operators at the boycotted stations.

Better explanation on my posts below.
