Not knowing which engine you have my answer is park the vehicle on a level surface. Drain the oil and change the filter. Add 5 quarts of the correct weight oil and start the engine. Let run for 1 minute and shut down. Wait 30 minutes and check the oil level. Add as necessary to reach the full mark if it is low. You now know the capacity. Do not overfill.
