CAR CARE & DRIVING TIPS

Top 10 Tips for Improving Your Fuel Economy

from the editors of www.edmunds.com

Filling up is a fact of every driver's life, but for some drivers it is a necessary evil. If you are one of those people who gulps every time you have to fill up your vehicle, there's good news: there are some simple things you can do to improve your fuel economy no matter what type of vehicle you drive.

Monitoring your average fuel economy regularly is a good idea, too. (Some vehicles have a handy computer that computes this for you.) If you notice a significant change, then something has changed with your vehicle.

Here are 10 things you can do today to get better gas mileage right away.

  • Follow the Recommended Maintenance A vehicle that is well maintained means it will operate with greater efficiency. This not only improves your overall vehicle performance, but it will improve your fuel economy as well. Fouled spark plugs, a dirty air filter or clogged fuel filter will all affect your fuel economy. According to the U.S. Department of Energy (DOE), replacing a clogged air filter can increase your mileage by 10 percent, while replacing an oxygen sensor could result in an improvement as high as 40 percent. Proper maintenance also means using the right octane gas and the recommended grade of motor oil. Using the recommended types for your vehicle will give you optimum fuel economy — and can save you money as well. Check your owner's manual for your vehicle's recommendations and have maintenance performed regularly by a dealer or reputable mechanic.
  • Keep Your Tires Properly Inflated Underinflated tires require more energy to roll, which translates into more frequent fill-ups. You can improve your fuel economy by about 3.3 percent if you keep your tires inflated properly, according to the DOE. The psi number noted on the sidewall of your tires is the maximum pressure of the tire and is not the proper inflation level for your car. Your vehicle manufacturer will list the recommended tire pressure in your owner's manual or a sticker on the doorjamb of the driver-side door. Buy a tire-pressure gauge and check your tires monthly, adding air as necessary.
  • Take a Load Off Heavier vehicles require more energy to move, so carrying around excess weight will also affect your mileage. Empty out your trunk (or even your backseat) of unnecessary items. An extra 100 pounds in the trunk will reduce your fuel economy by 1 to 2 percent in the typical vehicle. If you have a roof rack or roof carrier, install it on your vehicle only when absolutely necessary. Not only does the carrier add extra weight, but it also increases the aerodynamic drag on the vehicle, which further contributes to a loss of fuel economy.
  • Don't Drive Aggressively We're not talking road rage here, but the type of driving many people do when they are in a rush. Mashing the accelerator pedal from a stoplight, braking hard and speeding all contribute to a decrease in fuel economy. Give yourself extra time to get to your destination and think "steady and smooth" as you drive. On surface streets, driving at the speed limit will give you mostly green lights, which improves your gas mileage as well as reduces the wear on your brakes. On the highway, the DOE says that every 5 mph you drive over 65 mph represents a 7-percent decrease in fuel economy.
  • Use the Highest Gear Possible Cars are designed to start in the lowest gear possible because that's where they have the most power, but that power translates to an increase in fuel consumption. To improve your fuel economy, drive in the highest gear possible when you are cruising at a steady speed, such as on the highway. If your vehicle has an automatic transmission with a "sport" mode, it's most likely that this is a computer program designed to shift later (and therefore keep you in a lower gear longer). While this gives you greater performance, driving in "sport" mode will also decrease your fuel economy.
  • Use Cruise Control — Selectively Using cruise control can improve your gas mileage by helping you maintain a steady speed, but only if you are driving on mostly flat roads. If you are driving in hilly terrain, using cruise control typically causes your vehicle to speed up faster (to maintain the preset speed) than it would if you were operating the accelerator yourself. Before you push that cruise control button, think about the terrain ahead.
  • Think Clean Keeping your car washed and waxed improves aerodynamics and therefore affects fuel economy. Engineer Tom Wagner, Jr. reported to Stretcher.com (as in stretching your dollars) a 7-percent improvement in fuel economy, from 15 to 16 mpg, during a 1,600-mile road trip.
  • Avoid Excessive Idling When a car is idling, it is using fuel, yet not going anywhere. This translates to 0 mpg. When you leave your car running while you are waiting in line at the drive-thru, or as you wait outside your kids' school, you are wasting fuel. It is more efficient to turn the engine off while you wait and then restart the car. If that's not practical (like in the line at McDonald's), then park the car and go inside instead.
  • Think Before You Vent(ilate) Running your air conditioner does cause your vehicle to consume more fuel, but driving with your windows rolled down can be even worse due to the increase of drag on the vehicle. If you are driving slowly, such as around town or in city traffic, then you are better off leaving your windows open, if at all possible. For highway driving, roll up the windows and turn the air conditioning on.
  • Combine Your Errands A little planning can make a big difference in fuel economy. When your engine is cold, it uses more fuel than when it is warm. Combining errands can improve your gas mileage because your engine will be warm for more of the trip. It might also mean you travel less total miles. According to the DOE, several short trips all begun with a cold start can use twice as much fuel as a single, longer trip that covers the same distance.

Top 10 Ways to Prevent an Accident

from the editors of www.edmunds.com

It's so much easier to prevent accidents than to deal with the painful consequences of a chance encounter. However, most motorists spend very little time learning how to drive more safely. Everyone is in such a rush to arrive that we cut corners and take chances. We would like to put a stop to that by providing a list of commonsense safety reminders. Following the tips below — and incorporating them into your driving habits — will greatly increase your chances of safely arriving at your destination.

  • Carefully look both ways — twice — before entering an intersection. It's easy to miss an oncoming car at first glance because it's hidden by your car's windshield frame. A second look only takes a second and it might avoid a serious collision.
  • Don't accelerate into an intersection the instant the light turns green. This is a good way to get rammed by someone running the red light who's coming from the other direction.
  • Look right before pulling out. After waiting for traffic from the left to clear before you make your right-hand turn, don't forget to look to the right again just before you proceed. Pedestrians or cars may have suddenly materialized in your path while you were waiting to turn.
  • Anticipate unexpected changes in traffic. For example, if you're in a fast-moving lane with empty road ahead and the next lane over is backed up, be prepared for impatient motorists to dart into the lane in front of you.
  • Know your blind spots. Find out where your blind spots are when checking the road behind you in your mirrors. You might have to turn to look directly into the lanes beside you to avoid missing something left undetected by your mirrors. This is particularly important when changing lanes — don't just rely on your mirrors.
  • Watch other drivers' blind spots. Practice extra caution when passing large vehicles, such as semi trucks, which have less maneuverability and even larger blind spots. If you can't see a truck's mirrors, chances are its driver can't see you.
  • Watch for children and pets. Pay special attention to posted speed limits around schools and in residential areas; children and pets may unexpectedly dart into the street.
  • Don't tailgate. Leave enough space between yourself and the car ahead of you, when traveling and when stopped. On the highway, this may save you from a fender bender. Remember to leave even more room if the roads are slick. If you stop on a hill behind a car with a manual transmission, the extra room may save you from being rammed if the car slides back. Leaving yourself extra room can also help you make a quick exit if you're approached by a carjacker in a dubious neighborhood.
  • Keep your car operating safely. Don't procrastinate about performing safety maintenance and repairs on your car. Check tire tread depth and pressure regularly. Have your brakes checked and wheels aligned as soon as they need it.
  • Go back to school. Go to a high-performance driving school to learn accident avoidance maneuvers and how to control skids. Understanding how to make your car do what you want it to do in emergency situations could save your life.
