Sure, there's no way to make $4-a-gallon gas seem anything less than excruciating. But there are some things you can do to make sure your tank and your wallet stay full longer.
What You Can Do
Driving less and switching to a more efficient vehicle are the two most obvious - though not the easiest - gas savers. In the United States, it is difficult to get around without getting into a car for a significant portion of time. Cities are very spread out, with people often living miles from their place of work and from anything at all. Public transportation is virtually non-existent, with very few exceptions. While many cities are making cities more accessible to non-motorists by adding bike lanes and wider sidewalks, the problem of distance still remains.
Switching to another, more efficient vehicle is not always easy either. However, it is possible to trade in your gas-guzzler for something more suited to today's gas prices. Hybrids, of course, are the greatest, but they are expensive and it's hard to trade-in for them.
However, there are more things you can do to improve your mileage and limit your donations to Exxon-Mobile.
Drive Conservatively: Driving aggressively often involves rapid acceleration and deceleration, which can lower your mileage by as much as 30%. In keeping with this concept, using Cruise Control can raise your mileage by as much as 10%.
Follow the Speed Limit: The most gas-efficient speed is 45 miles per hour. At speeds over 60 mph, your gas mileage decreases rapidly - for every 5 mph you drive over 60, it's as though you're paying $.20 more per gallon.
Take Care of Your Engine: Getting regular tune-ups keeps your engine running as it should and prevents major problems from ocurring. Fixing a big problem with an engine can save you hundreds of dollars per month.
Replace Air Filters: Replacing a clogged Air Filter can improve your mileage by as much as 15%.
Inflate Your Tires: Keeping your tires at the proper level can save you a lot of gas. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
Use the Recommended Motor Oil: Using the manufacturer's grade of motor oil can improve your mileage by up to 5%. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.
