Yamaha XMAX 300 Gear Oil Capacity (2017-2024)

The Yamaha XMAX 300 is an automatic scooter produced by Yamaha since 2017. This scooter uses an automatic transmission type, meaning the transmission oil is different from engine oil. The transmission oil is located at the rear, near the wheel behind the CVT. For instructions on changing the oil, transmission oil capacity, and regular oil replacement intervals, follow the steps below:

1. Pre-ride Inspection

Before each ride, examine the final transmission case for any signs of oil leakage. If any leakage is detected, promptly consult a Yamaha dealer for inspection and repairs.

2. Final Transmission Oil Change Procedure

Change the final transmission oil at the intervals specified in the xmax 300 periodic maintenance and lubrication chart. Follow these steps:

1. Warm Up the Oil
   Start the engine and warm up the final transmission oil by riding the scooter for several minutes, then turn off the engine.

2. Stabilize the Scooter
   Place the scooter securely on the centerstand to prepare for the oil change.

3. Prepare for Draining
   Position an oil pan under the final transmission case to collect the used oil.

4. Remove the Oil Filler Cap
