One of the reassuring qualities of contemporary cars is that they need much less-frequent service to keep them running well. Changing the spark plugs, breaker points, and condenser used to be a seasonal exercise, and body rust was accepted as a normal if unfortunate hazard of aging. Now many spark plugs can go 100,000 miles between changes. Electronic ignition has done away with the points and condenser. Chassis, suspensions, and even some transmissions are lubed for life. And factory rust-through warranties typically run six years or longer. What’s more, reliability has improved significantly. The result is that most late-model cars and trucks should be able to go 200,000 miles with regular upkeep.

When you buy a new car, you may ask how to maintain your new car and want to prolong your car’s life.

Here are a few simple, periodic checks and procedures you can do that will help you get there.

1.       Check the engine oil

The first key way to maintain your new car is checking the engine oil regularly—monthly for a vehicle in good condition; more often if you notice an oil leak or find you need to add oil routinely. The car should be parked on level ground so you can get an accurate dipstick reading. Don’t overfill. And if you do have a leak, find and fix it soon.

2.       Check tire air pressure

The second key way to maintain your new car is checking tire air pressure once a month and before any extended road trips, use an accurate tire-pressure gauge to check the inflation pressure in each tire, including the spare. Do this when the tires are cold (before the vehicle has been driven or after no more than a couple of miles of driving). Use the inflation pressure recommended by the vehicle’s manufacturer, not the maximum pressure embossed on the tire’s sidewall. The recommended pressure is usually found on a placard on a front doorjamb, in the glove compartment, or in the owner’s manual. Also be sure to inspect tires for abnormal or uneven wear, cuts, and any sidewall bulges you can see.

3.       Give it a wash

The third key way to maintain your new car is to try to wash the car every week, if you can. Wash the body and, if necessary, hose out the fender wells and undercarriage to remove dirt and road salt. It’s time to wax the finish when water beads become larger than a quarter.

Meanwhile, when your car running for 20000miles, there other things you need to pay attention.

For normal driving, many automakers recommend changing the engine oil and filter every 7,500 miles or six months, whichever comes first. This is sufficient for the majority of motorists. For “severe” driving—with frequent, very cold starts and short trips, dusty conditions, or trailer towing--the change interval should be shortened to every 3,000 miles or three months. (Check your owner’s manual for the specific intervals recommended for your vehicle.) Special engines such as diesels and turbocharged engines may need more-frequent oil changes.

1.       Check the air filter

Remove the air-filter element and hold it up to a strong light. If you don’t see light, replace it. Regardless, follow the recommended service intervals.

2.       Check the constant-velocity-joint boots

On front-wheel-drive and some four-wheel-drive vehicles, examine these bellowslike rubber boots, also known as CV boots, on the drive axles. Immediately replace any that are cut, cracked, or leaking. If dirt contaminates the CV joint it can quickly lead to an expensive fix.

3.       Inspect the exhaust system

If you’re willing to make under-car inspections, check for rusted-through exhaust parts that need replacing. Also tighten loose clamps. Do this while the car is up on ramps. If a shop changes your oil, have them make these checks. Listen for changes in the exhaust sound while driving. It’s usually advisable to replace the entire exhaust system all at once rather than to repair sections at different times.

4.       Look at the brakes

For most people it makes sense to have a shop check and service the brakes. If you handle your own brake work, remove all wheels and examine the brake system. Replace excessively worn pads or linings, and have badly scored rotors or drums machined or replaced. The brakes should be checked at least twice per year; more often if you drive a lot of miles.

5.       Check the fluids

On many newer cars, the automatic transmission is sealed. On cars where it is not sealed, check the transmission dipstick with the engine warmed up and running (see the owner’s manual for details). Also check the power-steering-pump dipstick (it’s usually attached to the fluid-reservoir cap) and the level in the brake-fluid reservoir. If the brake-fluid level is low, top it up and have the system checked for leaks.

6.       Clean the radiator

Prevent overheating by removing debris with a soft brush and washing the outside of the radiator with a detergent solution.

7.       Check the battery

Check the battery’s terminals and cables to make sure they are securely attached, with no corrosion. If the battery has removable caps, check its fluid level every few months—especially in warmer climates.
