Oil Change Intervals
The Lifan 125cc engine has a relatively small oil capacity, making regular oil changes especially important.
A recommended maintenance schedule includes:
- First oil change after 100–200 miles during the break-in period
- Every 500–1,000 miles during normal riding
- Every 300–500 miles when riding in dusty, muddy, or off-road conditions
- At least once every year, regardless of mileage
Fresh oil helps reduce engine wear, improves cooling, and removes contaminants that build up over time.
How to Change the Oil
Changing the oil on a Lifan 125cc engine is a simple maintenance task.
Step 1: Warm the Engine
Start the engine and let it idle for three to five minutes. Warm oil drains more completely.
Step 2: Turn Off the Engine
Park the motorcycle on level ground and switch off the engine.
Step 3: Drain the Old Oil
Place a drain pan beneath the engine and remove the drain bolt.
Allow all of the old oil to drain completely.

Step 4: Clean the Oil Screen
Most Lifan 125cc engines use a reusable oil screen instead of a replaceable oil filter.
Remove the screen, clean it thoroughly, and reinstall it before refilling the engine.
Step 5: Reinstall the Drain Plug
Reinstall the drain bolt and tighten it securely without overtightening.
Step 6: Add New Oil
Fill the engine with approximately 900 ml (0.9 liters) of fresh motorcycle oil.
Pour slowly to avoid overfilling.
Step 7: Check the Oil Level
Use the dipstick to verify the oil level.
The oil should be between the minimum and maximum marks, preferably near the upper mark without exceeding it.
Step 8: Start the Engine
Run the engine for one minute.
Turn it off, wait a few minutes for the oil to settle, then check the level once more and add oil if necessary.
