How to Change Engine Oil for SYM 125 Jet Power Scooter | Maintenance Operations

Today, I want to show you how to change the engine oil for SYM 125 Jet Power scooter. Most scooters should have an oil change between 3000 KM to 5000 KM. What happens if you do not change the engine oil?

1. Stall after started.
2. Engine failure.
3. Engine overheats.

When to change the engine oil?

1. Every 3000 KM or 6 months, whichever comes first.

Step:

1. Remove tappel adjusting hole cap (engine oil cap). 
   
   

   

   
   
2. The engine oil cap comes with an oil filter screen and spring.
   
   

   

   
   
3. Remove oil level gauge (dipstick).
   
   
   
   
   
4. After draining out the oil, clean the engine oil cap, oil filter spring, and screen.
   
   
5. It is recommended to replace the o-ring every time you change the engine oil.
   
   

   

   
   
   
   
   
6. Stack the engine oil cap with the oil filter spring and screen.
   
   

   

   
   
7. Reinstall engine oil cap, oil filter spring, and screen.
   
   

   

   
   
   
   
   
8. I use YAMALUBE 4T AT SAE 20W-40 engine oil.
   
   

   

   
   
9. Fill the engine oil around 600 ml. Note: use a funnel to prevent spillage of engine oil.
   
   
   
   
   
10. Install dipstick.
    
    
    
    
    
11. Start the engine and let it idle for 5 minutes, then turn it off.
    
    
    
    
    
12. The reading you get from pulling the oil level gauge for the first time is inaccurate. Wipe and reinsert the dipstick, then remove the dipstick again. Note: Ensure the oil level is between the minimum and maximum indicator.
    
    
    
13. If the indicator is below the minimum, you need to refill the engine oil. However, if the indicator is higher than the maximum, you need to drain engine oil.
    
    
14. If everything is within the range, install the dipstick.
