• Upgrade your motor oil. According to multiple independent university tests, Royal Purple motor oil improves fuel economy by as much as 5 percent and produces notable horsepower and torque improvements. That means motorists could save gas without giving up performance.

• Follow the maintenance recommendations in your vehicle's owner's manual. An out-of-tune engine can increase fuel consumption by as much as 15 percent. Always follow your car manufacturer's suggested tune-up schedule.

• Lighten your load. Don't carry extra weight in your vehicle. Doing so burns extra gas and could cost you money. Only carry sandbags, tools and other heavy items when you think you'll be needing them. Also, don't forget that carrying lots of small, light items can be the same as carrying one heavy item. Be sure to clean your trunk and backseat out regularly.
