Gas Is Money

If you'll be hitting the road for your getaway, buy regular octane (low-grade) gasoline unless your vehicle calls for "premium fuel" only, and save up to $150 per year in gasoline expenses.

For a standard engine, switching from premium fuel to regular unleaded gasoline results in more complete fuel combustion, which improves gas mileage and reduces smog-forming tailpipe emissions.
