That $720 is the estimated savings for a 90-gallon-burning family if gasoline prices remain depressed for an entire year. I'm not in a hurry to call all that money banked yet!
LOL. Just looked it up in Mint and I spent 0.9% of my after-tax income on gas in 2013.And I actually work for an oil and gas company, so I don't like these low oil prices at all. Balls.
Those numbers are bogus, who can afford to get by with just 90 gallons a month?
90 gallons per month? I can't even imagine. That's enough to drive a Prius the circumference of the earth about twice per year.
