Going that Extra Mile
These suggestions come from About.com's car editor, Aaron Gold, who ends his list of easy fuel-saving tips with this slightly more challenging one: don't drive. "Not a popular thing to say on a car site," he writes, "but the fact is that if you can avoid driving, you'll save gas. Take the train, ride your bike, carpool, consolidate your shopping trips. And always ask yourself: 'Is this trip really necessary?'"
