Inflate Your Tires Some More

I looked for total gasoline consumption in the United States per year and found it to be 2.5 billion barrels. One barrel is 42 gallons, so the United States uses 106 billion gallons of oil per year. 700 million gallons saved equals 0.65% of 106 billion gallons total. How does Exxon Mobil stand to benefit from creating an advertisment telling us we could save less than one percent of our total gasoline consumption? They obviously didn't count on people taking the time to do the calculations to figure out they're selling us a scam, but what their exact goals are and how they stand to profit from this, I do not yet know.
