What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not 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 or properly dispose of 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 threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-12 for location of engine air cleaner/filter and change indicator (if equipped). When to Inspect If your vehicle is equipped with a filter change indicator it lets you know when the filter needs to be replaced. Vehicles with a restriction indicator, inspect the air cleaner/filter at every oil change and replace the filter when the indicator tells you to. Vehicles without a change indicator, inspect the air cleaner/filter at every oil change and replace it at the first oil change after 25,000 miles (40 000 km). 5-21
