Engine Oil Additives Don't add anything to your oil. Your Oldsmobile retailer is ready to advise if you think something should be added. Engine Coolant Heater (Option) An engine coolant heater can be a big help if you have to park outside in very cold weather, 0°F (- 18OC) or colder. If your vehicle has this option, see "Engine Coolant Heater" in the Index. When to Change EngineOil See if any one of these is true for you: Most trips are less than 5 to 10 miles (8 to 16 krn). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). Most trips are through dusty areas. 0 What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for 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 or properly throw 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. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don't ever dispose of oil by putting it in the trash or by 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 retailer, a service station or a local recycling center for help. You frequently tow a trailer or use a carrier 011 top of your vehicle. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles ( 5 000 km) or 3 months -- whichever comes first. If none of them is true, change the oil and filter every 7,500 miles (12 500 km) or I2 months -- whichever comes first. 6-16
