ADVISOR Cool Down the Electric Bill Before it gets too hot this summer, add weatherstripping and caulking around windows and doors. This will limit air leaks that could account for 15 to 30% of the energy needed to cool your home, according to the Edison Electric Institute. Visit usaa.com/hometips for a monthly home guide. AUTO NOTES 5 Mileage Tips Hiding Right Under Your Nose Nothing says road trip like the recent drop in fuel prices. Even better, you can save more money on gas costs - and pad your vacation budget - by understanding fuel efficiency. Often, the keys to getting the best mileage from your car are hiding in plain sight and can add 25% or more to the travel distance between fill-ups. 1 YOUR TIRE GAUGE MATTERS 2 MIND THE LITTLE THINGS Many people inspect their tires for air pressure before the big road trip. But did you know that digital and dial gauges typically are more accurate than the pressure gauges hanging from the gas station air pump? Digital gauges can be had for less than $10. By properly inflating tires, you can improve gas mileage by 3.3%, according to the Energy Department. While you're at it, make sure to check on the spare. Unusual suspects, such as broken gas caps, can affect gas mileage. If your gas cap is cracked, replace it. Also, misfiring spark plugs can be a drain on your fuel economy. Have them checked and replaced if necessary.

The best bet: Have it cleaned during every oil change. A faulty oxygen sensor can cause excessive fuel consumption, too. Have it checked out before you hit the road. 4 FOLLOW INSTRUCTIONS Using the manufacturer's recommended grade of motor oil can increase your gas mileage by as much as 2%. Refer to your owner's manual to learn which engine oil is best. There is a tipping point at which lugging your own supplies and equipment causes a decrease in your gas mileage. Rooftop cargo bags or boxes can reduce efficiency by as much as 25% by causing aerodynamic drag. For every 100 pounds you add in weight, you reduce your mpg by about 1%. So, think twice before packing giant suitcases, golf clubs and bicycles. 5 3 4 2 1 ILLUSTRATION BY BRYAN CHRISTIE DESIGN http://usaa.com/hometips?wa_ref=USAAmag http://usaa.com/autocircle?wa_ref=USAAmag
