How do I change the oil

To change the oil in a TNG Low Boy 150cc LB150T-L:

1. Place the scooter on a level surface and put it on the center stand.
2. Turn off the engine and let it sit for a few minutes.
3. Remove the oil dipstick, wipe it clean, and reinsert it without screwing it in to check the oil level.
4. If the oil level is low, add Opti-4 lubricating oil until it is near the high mark.
5. For an oil change, locate and remove the oil drain plug to drain the old oil.
6. After draining, reinstall the drain plug securely.
7. Refill with Opti-4 oil to the correct level, using the dipstick to check.

Note: If riding under severe conditions (gravel roads or frequent stop-and-go traffic), change the oil more often than every 4000 km.
