How do you change the oil in a Yamaha jog?

To change the oil in a Yamaha Jog, first ensure the scooter is on a level surface and the engine is warm for better oil drainage. Remove the oil drain plug, allowing the old oil to fully drain into a container, then replace the plug. Next, remove the oil filler cap, add the recommended type and amount of new oil using a funnel, and finally replace the filler cap. Always check the oil level with the dipstick to ensure it's at the correct level after the change.
