It's Time for the 21st Century Tune-up

Times are changing...cars are changing. One of the biggest changes in today's automotive industry is the perception of a "tune-up." Ask 10 vehicle owners their definition of a tune-up and chances are there'll be 10 different answers. The classic "tune-up" was once the heart of the automotive business and contrary to some beliefs; today's modern vehicles still need tune-ups to keep them performing at the most efficient levels.

The tune-up was historically associated with the routine replacement of key ignition system parts like spark plugs and ignition points, along with some basic adjustments to help "tune" the engine. Mounting pressure for increased fuel economy and lower emissions drove the car manufacturers to adopt electronics and to do away with ignition points in the '70s, along with the carburetor in the middle '80s. This eliminated the need for the replacement and adjustment of a growing number of ignition and fuel system parts.

As the pace of technology quickened, the procedures required to perform a traditional tune-up changed dramatically. Highly sophisticated ignition and fuel systems are now the norm, using one or more onboard computers to control critical engine and transmission management functions. Things that were once handled mechanically are now controlled electronically through the widespread use of onboard computer technology.

Because vehicles have changed so much over the years, the Car Care Council has introduced the 21st Century Tune-up. This program is designed to help re-define and educate motorists as to what a tune-up should consist of on today's modern vehicles.

"There is a misconception that today's modern vehicles don't need tune-ups because they never break down, but that simply is not true," said Rich White, executive director of the Car Care Council. "If you're at work and your computer goes down, you can't get any more work done. It's the same with your vehicle. If the vehicle isn't being properly maintained, you're not going to get where you want to go."

As part of the 21st Century Tune-up on today's modern vehicles, the following systems should be inspected:

• battery, charging and starting
• engine mechanical
• powertrain control (including onboard diagnostic checks)
• fuel
• ignition
• emissions

Vehicle owners ask for tune-ups for a variety of reasons, including improving performance, maintaining reliability, planning a vacation, preparing for winter/summer or because they're giving the car to a friend or family member.

To help ensure good performance, fuel economy and emissions, the Car Care Council also recommends that motorists take the time necessary to become familiar with their vehicle from every aspect. Study the owner's manual to become thoroughly acquainted with the operation of all systems. Pay special attention to the indicator lights and instruments.

Keeping Your Vehicle in Tune with the Environment

Car care is definitely a win-win situation. Besides helping the environment, a properly maintained and operated vehicle will run more efficiently, will be safer, and will last longer-up to 50% longer, according to a survey of ASE-certified Master Auto Technicians. The following tips should put you on the road to environmentally conscious car care.

• Keep your engine tuned. A misfiring spark plug can reduce fuel efficiency as much as 30%. Follow the service schedules listed in your owner's manual. Replace filters and fluids as recommended.
• Check your tires for proper inflation. Under inflation wastes fuel-your engine has to work harder to push the vehicle. Wheels that are out-of-line (as evidenced by uneven tread wear or vehicle pulling) make the engine work harder, too. Properly maintained tires will last longer, meaning fewer scrap tires have to be disposed.
• Keep your air conditioner in top condition and have it serviced only by a technician certified competent to handle/recycle refrigerants. Air conditioners contain CFCs-gases that have been implicated in the depletion of the ozone layer. According to the Environmental Protection Agency, almost one third of the CFCs released into the atmosphere come from mobile air conditioners; some simply leaks out, but the majority escapes during service and repair-so it's important to choose a qualified technician.
• Do-it-yourselfers: dispose of used motor oil, anti-freeze/coolant, tires, and old batteries properly. Many repair facilities accept these items. Or call your local municipal or county government for recycling sites. Never dump used oil or anti-freeze on the ground or in open streams.
• Observe speed limits. Mileage decreases sharply above 55 mph.
• Drive gently. Avoid sudden accelerations and jerky stop-and-go's. Use cruise-control on open highways to keep your speed as steady as possible.
• Avoid excessive idling. Shut off the engine while waiting for friends and family. Today's vehicles are designed to "warm up" fast, so forget about those five-minute warm ups on cold winter mornings.
• Remove excess items from the vehicle. Less weight means better mileage. Store luggage/ cargo in the trunk rather than on the roof to reduce air drag.
• Plan trips. Consolidate your daily errands to eliminate unnecessary driving. Try to travel when traffic is light to avoid stop-and-go conditions. Join a car pool.

Remember, how your car runs, how you drive it, and how its fluids, old parts, and tires are disposed of all have serious consequences on the environment.
