When to Change Engine OilSee if any one of these is true for you:0Most trips are less than 5 to 10 miles (8 to 16 km).This is particularly important when outsidetemperatures are below freezing.Most trips include extensive idling (such as frequentdriving in stop-and-go traffic).Most trips are through dusty areas.You frequently tow a trailer or use a carrier on top ofyour vehicle.The vehicle is used for delivery service, police, taxior other commercial application.Driving under these conditions causes engine oil tobreak down sooner. If any one of these is true for yourvehicle, then you need to change your oil and filterevery 3,000 miles (5 000 km) or 3 months -- whicheveroccurs first. (See “Change Oil Soon” in the Index.)If none of them is true, change the oil and filter every7,500 miles (12 500 km) or 12 months -- whicheveroccurs first. Driving a vehicle with a fully warmedengine under highway conditions causes engine oil tobreak down slower.If the optional CHANGE OIL SOON light comes on,you will need to change your oil sooner than eithermileage specified. Depending upon driving habits, theCHANGE OJL SOON light may come on as early as2,000 miles or less from the last time the oil life monitorwas reset. (See “Oil Life Monitor” in the Index.) Alwaysreset the oil life monitor after every oil change.What to Do with Used OilDid you know that used engine oil contains certainelements that may be unhealthy for your skin and couldeven cause cancer? Don’t let used oil stay on your skinfor very long. Clean your skin and nails with soap andwater, or a good hand cleaner. Wash or properly throwaway clothing or rags containing used engine oil. (Seethe manufacturer’s warnings about the use and disposalof oil products.)Used oil can be a real threat to the environment. If youchange your own oil, be sure to drain all free-flowing oilfrom the filter before disposal.
