2004 Chevrolet Cavalier Owner's Manual - Page 226

Notice: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM Goodwrench® oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. • Most trips include extensive idling (such as frequent driving in stop-and-go traffic). • You frequently tow a trailer or use a carrier on top of your vehicle. • 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 true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months - whichever occurs first. If none of them is true, use the long trip/highway maintenance schedule. Change the oil and filter every 7,500 miles (12 500 km) or 12 months - whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower. Your vehicle has a unique oil filter element. When installing the filter cap do not exceed 18 lb-ft (25 Y). Inspect the condition of the O-ring and replace if damaged. See your dealer for additional information. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection. When to Change Engine Oil If any one of these are true for you, use the short trip/city maintenance schedule: • Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing. 5-16
