Gas Trix

I took a defensive driving class where they taught us some tricks to conserve on gas. They suggest that you drive no more that 55 mph and that if you see a yellow light try not to brake. Take your foot off of the gas and just cruise to the intersection. Chances are you don't have to stop and you can continue moving (it takes a lot of gas to go from a complete stop). So this isn't the best pic (nevermind the dust) but here's the point: I tried the suggestions I learned in the class and usually when I fill up I'd get like 425 MPG and this time I got 510MPG. I can't do the 55mph. I do 65mph and TRUST I get dirty looks on 75/85 but I'm saving on that gas money!!!
