When to Change Engine Oil See if any one of these is truefor you: Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such asfrequent driving in stop-and-go traffic). Most trips arethrough dusty areas. You frequently tow a traileror use a carrieron top of your vehicle. 0 If the optional CHANGE OIL SOON light comes on, you will needto change your oil sooner than either mileage specified. Depending upon driving habits, the CHANGE OJL SOON light may come on as early as 2,000 miles or less from the last time the oillife monitor was reset. (See "Oil Life Monitor" in the Index.) Always reset the oil life monitor after every oil change. What to Do with Used Oil Did you know that usedengine oil contains certain elements that may be unhealthyfor your skin and could even cause cancer? Don't let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash properly throw or away clothing or rags containing used engine oil. (See the manufacturer's warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. you If change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don'tever dispose of oil by putting it in the trash, pouringit on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place thatcollects used oil. If you have a problem properly disposing of your used oil, ask your dealer, aservice station or a local recycling center for help. The vehicle is used for delivery service, police, taxi or other commercial application. Driving under these conditions causes engine oil to break down sooner. If any one of these is truefor your vehicle, then you needto change your oil and filter every 3,000 miles (5 000 k ) 3 months -- whichever m or occurs first. (See "Change Oil Soon" in the Index.) If none of them is true, change the oil andfilter every 7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower.
