What to Do with Used Oil Used engine oil contains certain elements that can 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. Recycle it by taking it to a place that collects used oil. How to Inspect the Engine Air Cleaner/Filter (2.2L and 2.4L Engines) Engine Air Cleaner/Filter When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance on page 7‑3 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. The 2.0L engine inspect at each oil change. Replace filter if appears dusty or dirty. See Engine Compartment Overview on page 6‑16 for the location of the engine air cleaner/filter. To inspect the air cleaner/filter remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. Never use compressed air to clean the filter. 6-25
