That sounds good in theory but I'm not sure it's practical with prices where they are now. At roughly $3/gal, $10 = a little over 3 gal of gas. I probably use more than that in a single day. That means that, depending on how much is in my tank now and how much driving I have to do, I could potentially be buying gas 3 - 4 times a week. That's $30-$40 a week, about what it costs me to fill up my tank each week now. If prices were down in the mid $2 range, so that your $10 would go further, it might work. Math was never my strong subject so maybe I'm looking at this the wrong way.
