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 up to 50% longer, according to a survey of ASE-certified Master Auto Technicians.
The following links provide tips and information to help keep your vehicle running at top performance and put you on the road to environmentally conscious car care.
The Car Care Council offers these fuel-saving tips:
Vehicle gas caps - About 17 percent of the vehicles on the roads have gas caps that are either damaged, loose or are missing altogether, causing 147 million gallons of gas to vaporize every year.
Under-inflated tires - When tires aren't inflated properly, it's like driving with the parking brake on and can cost a mile or two per gallon.
Worn spark plugs - A vehicle can have either four, six or eight spark plugs, which fire as many as 3 million times every 1,000 miles, resulting in a lot of heat and electrical and chemical erosion. A dirty spark plug causes misfiring, which wastes fuel. Spark plugs need to be replaced as recommended by the manufacturer.
Dirty air filters - An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a "rich" mixture - too much gas being burned for the amount of air, which wastes gas and causes the engine to lose power. Replacing a clogged air filter can improve gas mileage by as much as 10 percent, saving about 20 cents a gallon.
Fuel-saving driving tips include:
Don't be an aggressive driver - Aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets, which results in 10 to 66 cents per gallon.
Avoid excessive idling - Sitting idle gets zero miles per gallon. Letting the vehicle warm up for one to two minutes is sufficient.
Observe the speed limit - Gas mileage decreases rapidly at speeds above 60 mph. Each mpg driven over 60 will result in an additional 10 cents per gallon. To maintain a constant speed on the highway, cruise control is recommended.
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
Powertrain control (including onboard diagnostic checks)
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.
Mechanical failure, an inconvenience anytime it occurs, can be deadly in the winter. Preventive maintenance is a must. Besides, a well-maintained vehicle is more enjoyable to drive, lasts longer, and could command a higher resale price.
Some of the following tips can be performed by any do-it-yourselfer; others require the skilled hands of a professional auto technician.
Engine performance - Get engine driveability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good repair shop. Cold weather makes existing problems worse. Replace dirty filters-air, fuel, etc.
Fuel - Put a bottle of fuel de-icer in your tank once a month to help keep moisture from freezing in the fuel line. Note that a full gas tank helps keep moisture from forming.
Oil - Change your oil and oil filter as specified in your manual; more often (every 3,000 miles) if your driving is mostly stop-and-go or consists of frequent short trips.
Cooling systems - The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of antifreeze and water is usually recommended.) DIYers, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
Windshield wipers - Replace old blades. If your climate is harsh, purchase rubber-clad (winter) blades to fight ice build-up. Stock up on windshield washer solvent-you'll be surprised how much you use. Carry an ice-scraper.
Heater/defroster - The heater and defroster must be in good working condition for passenger comfort and driver visibility. Newer models have a cabin air filter that should be replaced periodically. Check your owner's manual for the location and replacement interval.
Battery - The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check fluid level monthly. Avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
Lights - Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses. To prevent scratching, never use a dry rag.
Exhaust system - Your vehicle should be placed on a lift and the exhaust system examined for leaks. The trunk and floorboards should be inspected for small holes. Exhaust fumes can be deadly.
Tires - Worn tires will be of little use in winter weather. Examine tires for remaining tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. Check tire pressures once a month. Check the tires when they are cold before driving for any distance. Rotate as recommended. Don't forget your spare, and be sure the jack is in good condition.
Carry emergency gear: gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, and a flashlight. Put a few "high-energy" snacks in your glove box.
Summer's heat, dust, and stop-and-go traffic will take their toll on your vehicle. Add the effects of last winter, and you could be poised for a breakdown. You can lessen the odds of mechanical failure through periodic maintenance. Your vehicle should last longer and command a higher resale price, too!
Some of the following tips are easy to do; others require a skilled auto technician.
Air conditioning - A marginally operating system will fail in hot weather. Have the system examined by a qualified technician. Newer models have cabin air filters that clean the air entering the heating and air conditioning system. Check your owner's manual for location and replacement interval.
Cooling system - The greatest cause of summer breakdowns is overheating. The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of antifreeze and water is usually recommended.) DIYers, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
Oil - Change your oil and oil filter as specified in your manual-more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage, or tow a trailer.
Engine performance - Replace other filters (air, fuel, PCV, etc.) as recommended-more often in dusty conditions. Get engine driveability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good shop.
Windshield wipers - A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
Lights - Inspect all lights and bulbs; replace burned out bulbs; periodically clean dirt and insects from all lenses. To prevent scratching, never use a dry rag.
Tires - Have your tires rotated about every 5,000 miles. Check tire pressures once a month; check them while they're cold before driving for any distance. Don't forget to check your spare as well and be sure the jack is in good condition. Examine tires for tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. An alignment is warranted if there's uneven tread wear or if your vehicle pulls to one side.
Brakes - Brakes should be inspected as recommended in your manual, or sooner if you notice pulsations, grabbing, noises, or longer stopping distance. Minor brake problems should be corrected promptly.
Battery - Batteries can fail any time of year. The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check the fluid level monthly. Avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
Emergencies - Carry some basic tools - ask a technician for suggestions. Also include a first aid kit, flares, and a flashlight. Consider buying a cellular phone.
