Check the Engine Oil
    
    
        At least once a month, check the oil level with a cold car parked on level ground—or per the owner's manual.
    
 
    
        Assess the Air Filter
    
    
        Remove the air-filter element and hold it up to a strong light. If you don't see light shining through, replace it.
    
 
    
        Inspect Car Belts and Hoses
    
    
        With a cool engine, look for signs of wear, stress, and cracks among the hoses and belts. Feel for usually soft spots on hoses.
    
 
    
        Check 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.
    
 
    
        Wash the Car
    
    
        Wash the body with a car-specific soap and, if necessary, hose out the fender wells and undercarriage to remove dirt and road salt.
    
 
    
        Waxing
    
    
        Car wax offers a great way to protect your car from scratches and preserve  the shine, but even the best waxes last just a few weeks.
    
 
    
        Find a Shop for Your Brand of Car
    
    
        Many garages specialize in certain makes. Those that focus on your type are more likely to have the latest training and equipment to fix your vehicle.
    
 
    
        Check for Certification
    
    
        Your mechanic and shop should be certified by the National Institute for Automotive Service Excellence, or ASE.
