Gas prices are skyrocketing across the country. According to AAA, the national average for a gallon of regular fuel is $3.88 at the time of this writing. That is about a 33 percent increase from just one month ago. Last night I paid $5.09 per gallon for 94 octane. I could have gone out for a nice steak dinner for the price of filling my tank. So, in times like these, it is natural for people to try to get the most out of a gallon of gas.
