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. 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. 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, and emissions. 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. Study the owner's manual to become thoroughly acquainted with the operation of all systems. Pay special attention to the indicator lights and instruments. Getting Your Vehicle Ready for Winter Mechanical failure - an inconvenience anytime it occurs - can be deadly in the winter. Preventive maintenance is a must. 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 anti-freeze 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 floor boards 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 flash light. Put a few "high-energy" snacks in your glove box. Getting Your Vehicle Ready For Summer 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 anti-freeze 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. Keeping your vehicle in tune with the environment 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. Observe speed limits. Mileage decreases sharply above 60 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.

Courtesy of the Automotive Service Association The following simple and inexpensive preventive checks will greatly extend the life of the vehicle, ensure safer operation and even benefit the environment. Always consult your owner's manual for individual service schedules because maintenance requirements vary by manufacturer. Always consult your owner's manual, but a good rule of thumb is to have the oil filter changed regularly - every 3,000 to 4,000 miles. Have all fluids checked, including brake, power steering, transmission/transaxle, windshield washer solvent and antifreeze. These fluids play a large role in the safety and performance of the vehicle. Check tire inflation. Under-inflated tires can result in a loss of fuel efficiency. This is the least expensive form of preventive and safety maintenance. Tires should be checked once a month. Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency by as much as 30 percent. Have the chassis lubricated frequently. This step extends the life of the moving components of the vehicle's suspension system. Check battery cables and posts for corrosion and clean them as needed. The battery fluid also should be checked and filled if it is low, unless it is a maintenance-free battery. Have the lighting system checked frequently, including headlights, turn signals, and brake and taillights. Check windshield washer blades for cracks, tears and windshield contact. Replace them at least once a year, or sooner if streaking begins. Inspect engine belts regularly. Worn belts will affect the engine performance. Look for cracks and missing sections or segments. Have the air filtration system checked frequently. The air filter should be checked every other oil change for clogging or damage. This system ensures that the vehicle is performing at its peak condition.

An average of 13,000 Americans are killed between Memorial Day weekend and Labor Day, some as a result of unperformed vehicle maintenance, according to the National Highway Traffic Safety Administration. Each year, neglected maintenance leads to more than 2,600 deaths, nearly 100,000 disabling injuries and more than $2 billion in lost wages, medical expenses and property damage. Most mechanical failures can be traced to neglected maintenance. For example, the U. S. Department of Transportation reports the leading cause of mechanical breakdown on our nation's highways is overheating, a condition that is easily avoidable. Other deficiencies that are simple to detect include low antifreeze/coolant, worn or loose drive belts and defective cooling system hoses. Checking tire pressure and inflating a tire costs nothing, yet an average of 21 percent of cars inspected in check lanes during National Car Care Month have under inflated tires. This can lead to a blowout and a serious accident.

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. WIPERS - In the 2021 National Car Care Month vehicle check lanes, 21 percent of participants had wipers that smeared, streaked or chattered across their windshields. Although climates vary, wipers generally need replacing every six months. An easy reminder is to change wiper blades in the spring and fall when you change your clock. Be sure the windshield washers are working properly, too, and keep the reservoir filled with solvent. LIGHTING - Another important pre-trip check should be exterior and interior lighting. Vehicle check lanes revealed an overall failure rate of over 25 percent in the lighting category. The Car Care Council reminds motorists to check their lights monthly. Other suggestions from the Council include turning on headlights both day and night. This helps define your car's position on the road, and its distance from other drivers. When your vehicle's lighting is defective, other motorists may not get the message that you intend to stop or turn. The end result could be disastrous. 10 Minute Pre-Trip Checkup Can Pay Off Car Care Council offers three suggestions for a traveler's 10-minute pre-trip checklist: Check all fluids. There are several fluids, in addition to antifreeze, that require attention, including engine oil, power steering, brake and transmission fluids and windshield washer solvent and antifreeze/coolant. Check hoses and belts. A belt that fails can affect the electrical system, air conditioning and power steering, as well as the cooling system. Cooling system hoses may be deteriorating from within, so old hoses and clamps in marginal condition might need to be replaced. Check the tires. Check tire inflation and inspect the tread for uneven wear, indicating the need for wheel alignment. Also look for bulges and bald spots. "While a last minute checkup is better than no checkup, motorists should plan ahead to allow time to perform necessary maintenance themselves or at the local service facility. A properly maintained vehicle is safer and more dependable and will even save a few dollars at the gas pumps," said the Car Care Council's Executive Director, Rich White. Not only can a pre-trip inspection help reduce chances of costly and possibly dangerous road trouble, it also provides an opportunity to have repairs made at home, with one's own technician who knows the vehicle. Especially important, it provides peace of mind. While no inspection can guarantee a car's performance, it's comforting to know proper precautions were taken.

Not so fast! Often, it is cheaper to drive an older car with lower MPG than take on a car payment. We understand that times are difficult right now. Keep up with your auto maintenance, tire pressure, wheel alignments every 6 months, and routine inspections. New is not always the best option financially speaking for the pocket book.
