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.

Choose a good car insurer Sometimes, no matter how careful you are, disaster inevitably strikes — typically in the form of an accident. Make sure that your car will be repaired to the best possible standard by finding an insurer that will pay for parts from the original manufacturer and guarantee the repairs it authorizes.

Lighten up your key chain Does your car key share a chain with a dozen or more other keys? That’s a pretty heavy load hanging off the car key when it’s in the ignition.The weight, combined with bouncing while you drive, can wear out the tumblers inside the ignition and eventually lead to ignition switch failure.To add years of service to your ignition switch, purchase a lightweight key chain that allows you to separate your ignition key from the others. Drive with only the ignition key in your ignition. If your ignition key “sticks” when you try to turn on the car, it’s a warning that your ignition switch is about to fail. Replace it before you get stranded.

Park in the shade Of course, a garage is always the ideal place to park your car. But if one isn’t available, minimize interior damage from UV sunlight and heat by always trying to park your car in the shade. If no shade is available or if you find parking under a tree results in bird droppings, use a car shade to minimize the sun’s impact. As a bonus, you’ll have a cooler car to step into on hot sunny days. Car shades come in two basic types: those that you unfold and place on the front windshield and rear window, or pleated types that attach to the windshield posts (with adhesive), window frames (with Velcro), or the windows themselves (with suction cups).

Let floor mats take winter’s beating Use floor mats to protect carpeting. The best type for controlling salt, slush, and mud in winter are rubber wafflestyle mats. They stay in place, don’t allow the water to seep through, and are easy to wash clean. Carpet-style mats are helpful, too. Shake, vacuum, or wash as needed; replace them as they wear through.

Fill with washer fluid only Don’t add water to the windshield washer reservoir. It won’t clean as well as washer fluid, and it may freeze in cold weather and damage the system. Don’t try to run your windshield washer system once you suspect there’s no more fluid in the tank, or you may damage the washer fluid pump.

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.

Secure loads to avoid dents and scratches The beginning of the end for the finish on many cars and trucks — and for wagon and hatchback interiors for that matter — is an improperly stowed load. Invest in the appropriate racks for bicycles, cargo, and luggage. A good trick to keep tall objects from sliding around in a pick-up truck bed is to use a shower curtain rod (or two) as a brace. Just push the cargo against the front wall of the truck bed and install the rod behind it. Twist to secure. Cargo nets will also help keep objects from banging around and damaging a truck bed.

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.

Renew fabric upholstery Spraying fabric car seats and carpets with a fabric protectant, such as Scotchgard, will make them resist dirt and stains, and make them easier to clean. Thoroughly clean the fabrics before using one of these products and then test the product on an inconspicuous place to be sure the treatment will not discolor the fabric.

Beware the wet thumb If you top off your tires at a service station, check to see if there’s moisture coming from the air pump. Simply depress the pin inside the inflator valve with your thumbnail. If your thumb gets wet, advise the station manager that his tanks need to be drained and go to a different station. Moisture, trapped inside a tire, can cause pressure variations and corrode rims.

Have wheel alignment checked Have your car’s wheel alignment checked every 30,000 miles (48,000 km), or as recommended in your owner’s manual. Also have it checked after buying new tires and when you replace a rack-and-pinion steering unit or other steering parts. Improper tire alignment will shorten the life of your tires as well as cause poor handling. If your steering is stiffer than normal or the vehicle pulls to one side, you probably have an alignment problem.

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.

Avoid hose hassles Check the hoses under your hood every month or two to avoid the hassle of a broken hose while you’re on the road. With the car cool and off, squeeze the hoses. If they are hard or make a crunching sound, replace them. Ditto if they are extremely soft or sticky.With the car warm but off, examine hoses for bulges and collapsed sections. If you find any, the hose walls are weak, and it’s time to replace the hose. Never drive with a ruptured coolant hose, or you are liable to overheat the engine and damage it. Other hoses are crucial to operation of your power brakes and cruise-control systems.

Spark plugs do need changing The advent of electronic ignition and on-board computers has eliminated the need for regular tune-ups, but you still need to change your spark plugs. Many manufacturers recommend changing plugs every 30,000 or 40,000 miles (48,000 or 64,000 km) to ensure good fuel mileage and engine performance. Some new cars come with long-life plugs (sometimes called double platinum plugs) that can last for 100,000 miles (160,000 km). If your car isn’t so equipped, make the switch after 30,000 miles. The extra cost is only a few dollars per spark plug. While you’re at it, change your spark plug wires as well. Their typical life is 50,000 miles (80,000 km). Deteriorated wires can cause those high-tech new spark plugs to foul.

Seal a leaky radiator Save the high expense of a new radiator by trying to seal a leak with a radiator sealer, such as Alumaseal from Gold Eagle Co. Available in powder or liquid form, the product circulates in the radiator until it gets to the hole, where it sets up and fills the hole upon contact with the air. Alumaseal may be used to stop heater core leaks as well.

Check engine oil at every other fill-up For an accurate reading, follow this procedure:Run or drive your car for about 15 minutes to warm the oil; then park the car in a level place.Turn off the engine and wait 15 minutes to allow the oil in the engine to drain back to the oil pan.
Remove the dipstick and wipe it clean with a paper towel or rag. Reinsert the dipstick, being sure to push it in all the way, then pull it out again to check the oil level. It should be somewhere between the hash marks on the dipstick.
Add the type and amount of oil as specified in your owner’s manual, if necessary.

Consider adding oil coolers If you plan to do a lot of towing and your vehicle is not already equipped with coolers, consider having them added. Aftermarket engine oil and transmission fluid coolers are simple, low-cost addons that operate on the same principle as your car’s radiator. The fluid flows through them, and many small fins absorb and dissipate heat. Cooler operating temperatures of engine oil and transmission fluid can add significantly to the life of your engine and transmission.

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.

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.

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.

Rotate your tires Rotating your tires helps to distribute tire wear evenly and ensures that you’ll get the maximum road life out of them. The first rotation is especially important.Your owner’s manual should specify both rotation period and pattern. If not, rotate your tires every 6,000 to 7,500 miles (9,700 to 12,000 km) — your tire dealer should know the correct pattern of tire rotation.

Have wheel alignment checked Have your car’s wheel alignment checked every 30,000 miles (48,000 km), or as recommended in your owner’s manual. Also have it checked after buying new tires and when you replace a rack-and-pinion steering unit or other steering parts. Improper tire alignment will shorten the life of your tires as well as cause poor handling. If your steering is stiffer than normal or the vehicle pulls to one side, you probably have an alignment problem.

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.

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 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.

Lube your lug nuts Lug nuts, if not lubricated occasionally, can seize or “freeze” to the studs due to corrosion. Repairing them can be expensive. Having to call a tow truck for a flat you can’t remove is even more expensive.The next time you change or rotate your tires, pick up some anti-seize lubricant at your local auto supply store. Clean the stud threads with a wire brush and wipe them with the lubricant. It’s formulated to prevent the lug nuts (spark plugs, too) from seizing and won’t allow them to loosen as you drive, the way other lubricants might. If a lug nut does freeze to a stud, try spraying the nut and stud with WD-40 or Liquid Wrench. Allow it to penetrate for 10 or 20 minutes. Use a heat gun to apply heat.Then use a ratchet wrench to remove the lug.
