Nice find... I say that because I'm not knocking you in my next sentence
What I'd be interested in seeing is a per capita consumption graph. If everyone uses 40 gallons a month, and that drops to 38... But the population increases by 6%, that's nearly a 7% increase in consumption.
I personally have changed my habits of refueling. I apply my
Self Rationing scheme to the trends in the cost of fuel. If I'm anticipating fuel to go down, I'll try to avoid refueling (and only refuel a partial tank). If I know fuel will go up for a significant amount of time, I'll fill the tank. That on top of setting rationing based on the state of my fuel gauge (unless prices will rise)
