Pretty off topic, but saving money on a gallon of gas won't mean you use any less gas. You'll use the same amount of gas (or more/less if you drive around to stations you don't normally use). A better way to put your "13,020,000,000 billion gallons of gas saved a YEAR!" would be a dollar amount, because price is the only difference between the gallons of gas if you negate the distance traveled to said gas station(s). You'll potentially be saving money in your wallet, but you certainly aren't saving the world if you're still consuming the same amount of gas (regardless if you pay more or less for it)
