Air Conditioning: Make sure your air-conditioning is working efficiently. If in doubt, have it checked by a qualified professional. The most important benefit of effective air-conditioning is that it reduces driver fatigue, keeping the driver alert, refreshed and more comfortable.

Use your parking brake. Even if you are driving a car with an automatic transmission, use your parking brake regularly, especially if you're parked on an incline. It helps keep the brakes adjusted in the rear of the car and makes them last longer. Do not use your parking brake in the wintertime because your brake will freeze and it will be stuck until it thaws out.

Buy gas at reputable service stations Ask whether the gas you buy is filtered at the pump and if the station has a policy about changing the pump filters regularly. If you get a song and dance, find another gas station. Some stations don’t have pump filters, making you more vulnerable to dirty gasoline. Other stations may not mix alcohol and fuel properly — or worse, water down their product. Find a station you trust and stick to it.

Keep an auto log Keep a pad and pencil in the glove compartment and use them to record your gas fill-ups and mileage. If you notice that your gas mileage worsens, mention it to your service man. It may be an early warning sign that something is wrong with your car.

Clean dash gauges carefully Use a soft damp cloth to lightly wipe dust from the clear plastic lenses on your dashboard. Too much pressure will scratch them. Too many scratches can make it difficult to read your gauges under certain lighting conditions.

Blast mats with the hose When washing your car, drag out the rubber or carpet floor mats and blast them with the hose.This will dislodge dirt particles that, if allowed to build up, will grind holes in your mats. Let the mats dry thoroughly in the sun before reinstalling the

Keep leather from drying out and cracking Leather cars seats are durable and don’t require a lot of maintenance. After a few years, however, the seats can become soiled. Use a leather cleaner to remove dirt and stains.Then apply a leather protectant formulated for pigmented or top-coated grain leather (the leather used for most leather car upholstery). Protectants will resist stains and make the upholstery easier to clean in the future. Choose a protectant that includes conditioners to keep your leather supple

Clean the inside, too Vacuum and sponge your interior every time you wash your car. Dirt particles are abrasive, and spilled liquids, such as soda, can be corrosive.Vacuum your interior thoroughly with a powerful vacuum (small cordless models are generally too weak). Use the appropriate wand heads when vacuuming. The bare metal wand can mar and scratch surfaces. Sponge vinyl surfaces clean with a solution of mild detergent and water.

Buy used tires If you own a car that you plan to drive only for another year, the last thing you want to do is to buy a new set of tires. If it’s time to replace those tires though, it’s really time. Rather than hesitate, buy a set of used tires. Call local tire dealers to see what’s available. You’ll be surprised by how much wear is left in tires that are turned in by image-conscious car owners. Have your tire size handy

Use wheel cleaner Your car’s wheels are down there on the road, taking the brunt of road dirt. Add in the dust that wears off your brake pads and you’ve got a formula for stains that are tough to remove when you wash your vehicle. Car-washing liquid won’t do the job.You need a wheel cleaner specifically formulated to remove such stains. Be sure to buy the correct formulation. Some cleaners are designed for metal wheels, and others for painted or clear-coated wheels.The metal wheel cleaners come in various formulations as well, depending upon whether your metal wheel has a satin, aluminum, or chrome finish. Protect metal wheels with wheel polish, painted wheels with a coat of wax.

Avoid overfilling your crankcase with oil Don’t overfill your engine crankcase with oil. If you do, the oil can rise into the crankshaft, where air bubbles will get churned into the oil.Your oil pump can’t do a good job of circulating oil with air bubbles. The result can be overheating and stress on engine components. Overfilling can also foul your sparkplugs. In fact, overfilling is a bad idea with all automotive fluids.

Wipe oil pan plug clean If you do your own oil changes, clean the drain plug and washer with rags before re installing your oil pan. Some plugs are magnetized to trap metal particles.

Test drive-belt tension Check the tension and condition of your drive belt (or, with many cars, multiple belts) every month. Belts that are too tight can wear out the bearings in accessory components, such as AC compressor, water pump, and power-steering pump. Belts that are too loose will wear out faster and may fail prematurely. Perform your examination before you start the car to avoid injury due to a hot belt or moving engine part. Check for tension by pressing in the center of the belt’s longest exposed run while holding a ruler next to it. If you can depress the belt 1/ 2 to 1 inch (13 to 25 mm), but not more or less, the tension is good. If not, adjust the belt tension yourself according to your car’s service manual, or have your dealer or auto repair service do it. Also check for belt damage, such as glazing (often due to oil leakage), fraying, and cracks. If you spot damage, have the belt checked by a pro and replaced if necessary.

Some batteries need water If your battery has vent caps, remove them to check the level of the electrolyte. It should rise 1/2 inch (13 mm) above the battery’s top plates. If it doesn’t, use distilled water to raise the level to 1/4 or 3/8 inch (6 or 10 mm) below the bottom of the vent cap. Don’t use tap water, as it may contain minerals that can damage your battery. Mechanics should check your battery as a part of your regularly scheduled maintenance, but they often skip the procedure. Be sure to ask to have it done.

Don’t fill up if you see the tanker If you happen to see a gasoline tanker filling the tanks at your local gas station, come back another day or go to a different station. As the station’s underground tanks are being filled, the turbulence can stir up sediment. Sediment in your gas can clog fuel filters and fuel injectors, causing poor performance and possibly necessitating repairs.

Fuel Injection ServicePerforming a fuel injection service not only prolongs the life expectancy of the injectors, but can increase fuel mileage with benefits that far outweigh the cost of the service.

Annual or seasonal complete vehicle inspection Having your vehicle inspected periodically can prolong the life of many major components of your vehicle by diagnosing repair issues before
they become major problems, but don’t assume that getting your oil changed at a “quick lube” comes with a thorough inspection. Request a
copy of the check list and compare for yourself.

Drive with care everyday Being car considerate shouldn’t stop after the break-in. Drive with care every day and your car will reward you with longer intervals without repair.
Do not race your car’s engine during start-up.This is a quick way to add years of wear to your engine, especially if it’s cold outside.
Accelerate slowly when you begin your drive.The most wear to the engine and drive train occurs in the first ten to twenty minutes of operation.
Warming the engine by letting it idle in the driveway is not a smart idea.The engine doesn’t operate at its peak temperature, resulting in incomplete fuel combustion, soot deposits on cylinder walls, oil contamination, and ultimately damaged components.
Put less strain on your engine and automatic transmission by shifting to neutral at red lights. Otherwise, the engine is still working to push the car even while it’s stopped.
Avoid driving at high speeds and accelerating quickly, especially when it’s very hot or very cold outside. Such driving behavior will result in more frequent repairs.
Extend the life of your tires with careful driving. Observe posted speed limits. Avoid fast starts, stops, and turns. Avoid potholes and objects on the road. Don’t run over curbs or hit the tire against the curb when parking. And, of course, don’t burn rubber.
When turning your steering wheel, don’t hold it in an extreme right or left position for more than a few seconds. Doing so can damage the power-steering pump.
Consolidate your short driving trips. Most of the wear and tear — as well as the pollution your car generates — takes place in the first few minutes of driving. Doing several errands at once, during low traffic hours if possible, will keep your engine happier longer.

Use upholstery cleaners on soiled seats The same upholstery cleaners you use at home can be used on your car’s upholstery. Use them sparingly, however, to avoid saturating the fabric. Use a clean cloth to wipe away the foam. On velour seats, brush the fibers gently to avoid matting them and to preserve the original texture of the fabric.

Place a towel under baby seats All manner of food bits and liquids can accumulate under a baby seat, where they can permanently stain the upholstery. Place a sheet of heavy plastic and an absorbent towel under the seat to prevent damage, and re-secure the seat according to the manufacturer’s directions.

Fix small windshield chips Got a rock chip, crack, or ding in your windshield? Bring your car to a windshield repair shop. For far less cost than replacing the windshield, they can fix chips and cracks, even quite long ones. The repairs not only keep the chips and cracks from spreading and restore structural integrity, they also improve clarity.

When temperatures affect tire inflation When outside temperatures drop or soar, tires tend to lose pressure. A drop of 10 degrees F (6 degrees C), in fact, will decrease a tire’s air pressure by 1 or 2 pounds.Tires can lose even more air in hot weather. Under-inflated tires can result in accelerated wear and poor driving performance. If you live in a place where temperatures vary a lot, check your tire pressure often and add air as needed.

Run your AC in winter To keep your car’s air-conditioning system fit for the next warm season, run it a few times throughout the winter. This will prevent moving parts in the compressor from seizing. Also, circulating the refrigerant will help keep the seals soft and pliant.

Antifreeze maintenance Over the years, coolant-antifreeze breaks down and becomes susceptible to contamination, which will shorten the life of your vehicle. Follow your owner’s manual to get old antifreeze out of your car’s cooling system. Three years will be the breaking point for most antifreeze products, but it could happen sooner with cheap products. This bit of maintenance protects your radiator, keeps your heater from failing, and helps keep the car’s thermostat in working order.

Transmission maintenance Cars need fluid replaced in the automatic transmission every few years or 25,000 miles, depending on your make and model. Vehicles you use to tow need the fluid replaced more frequently. If you drive stick, manual transmissions need lubricant changes every 50,000 miles. Synthetic motor oil is the most recommended option for maintaining your vehicle longer, but your owner’s manual will have details for the particular model.

Maintain proper inflation Under-inflated tires are a tire salesman’s best friend. They create excessive heat and stress that can lead to tire failure. If you want to get every last mile out of your tires, get yourself a tire pressure gauge and use it at least once a month (more in hot weather) to keep your tires inflated to the recommendation in the vehicle’s owner’s manual. Check tires when they are cold (driven for less than one mile) for an accurate reading.

Don’t forget to flush Coolant-antifreeze eventually degrades and becomes contaminated. Flush it from your cooling system as recommended in your manual (typically every two years; every five years for newer coolants). Failing to do so can damage your radiator, clog your heater core, and cause the thermostat and water pump to fail.

Don’t mix coolants Avoid mixing coolants that are different in color. If your coolant is pink, don’t add a green formulation to it. Otherwise, you’ll end up with a thick solution that won’t do its job. Use only the coolant specified in your owner’s manual.

Maintain your transmission Change automatic transmission fluid and filter after the first 5,000 miles (8,000 km) and after every 25,000 miles (40,000 km) or two years thereafter, or as recommended in your owner’s manual. If you use your vehicle for towing, change the fluid and filter every year. For manual transmissions, change the lubricant (motor oil or gear oil, depending on the car) after the first 5,000 miles and after every 50,000 (80,000 km) thereafter. Use synthetic motor oil or gear lube for longer transmission life unless the manufacturer recommends otherwise.

Preserve door and window seals Wipe a rubber protectant (such as Armor-All) or silicone on door and window weatherstripping to keep it in good condition. Don’t use an oilbased product, such as WD-40, because the oil will damage the rubber. Regular cleaning and treatment of your car’s weatherstripping will also lessen the likelihood of your door sticking to its rubber seal in cold weather, a common cause of damage to the rubber.

Do not waste your money on fuel injector cleaning solutions found at gas stations and automotive stores. Most will not be able to unclog your injectors. The best and only method you can be sure of will be the ultrasonic fuel injector cleaning service. This is because they usually provide the test results before and after the service showing the improvements that were made.
