The oil capacity is easy to find out. Simply park the vehicle on a level service, drain the oil, and change the filter. Add 4 quarts of the correct weight oil. Start the engine and let run for 15 seconds. Shut down engine and wait 30 minutes. Check the oil level and add as necessary to reach the full mark. You now know the oil capacity. Do not overfill.
