What is the procedure for changing the engine oil?

Use SE, SF, SG, SH or SJ grade engine oil. Before draining engine oil, check for leaks. Drain oil by removing drain plug and reinstall securely with torque of 50 N·m (5.0 kg-m, 36.0 lb-ft). After draining, replace the filter, apply proper torque, fill to full level on dipstick after a three-minute run cycle, and check again until correct level is reached.
