Maintaining your 2013 KTM 150XC is essential for peak performance and longevity. Regular oil changes are a crucial part of this maintenance. This comprehensive, proprietary guide from MotoSport.com takes you through every stepfrom gathering the right tools to specific advice for your model. Follow these instructions for a clean and effective oil change every time.

Tools & Supplies Needed

  • T-handle or socket wrench (to remove the drain bolt)
  • Torque wrench
  • Drain pan or catch can (for used oil)
  • Funnel
  • Replacement crush washer for the drain bolt
  • Clean rags or shop towels
  • Pair of pliers (for snugging the fill cap; see specific tips below)
  • 0.8 liters of recommended gear oil
  • Magnetic drain plug cleaner (optional but useful)
  • Gloves (recommended)

Preparation

  • Let your engine warm up for a few minutes. Warm oil drains more easily and carries out more contaminants.
  • Ensure the bike is upright and secure using a stand for safety.
  • If your bike has a skid plate, consider removing it in advance for easy access to the drain plug. For stubborn or hard-to-remove plates, a funnel or oil change aid device can help channel oil cleanly past the obstacle.

Steps to Change the Oil

  1. Remove the Oil Fill Cap:
    • Begin by unscrewing the oil fill cap on the right side of the engine. This allows air flow and speeds up draining.
  2. Position the Drain Pan:
    • Place a drain pan directly under the drain plug to catch old oil.
  3. Remove the Drain Plug:
    • Using your T-handle or socket wrench, carefully unscrew the drain plug located at the bottom of the engine case. Be ready—oil will flow out quickly. Avoid dropping the plug into the pan.
    • If the engine has just been running, the oil may be hot. Use caution to avoid burns.
  4. Clean and Inspect the Drain Plug:
    • The 2013 KTM 150XC uses a magnetic drain plug which collects metal filings. Clean the magnet thoroughly; finding fine debris is normal.
    • Inspect the crush washer for wear or damage and always replace it with a new one to prevent leaks.
  5. Allow Oil to Drain Completely:
    • Let all the oil drip into the pan. Tilting the bike slightly (if safe and secure) may help remove any remaining oil.
  6. Reinstall the Drain Plug:
    • Once drained, reinstall the magnetic drain plug with the new crush washer.
    • Tighten it lightly by hand, then use a torque wrench to finish—set to 20 Nm (14.8 ft-lbs) as recommended by KTM for the 150XC model.
  7. Add New Gear Oil:
    • Insert a funnel into the fill port. Pour in 0.8 liters of the recommended gear oil slowly, avoiding spills.
    • Wipe away any excess oil from the case.
  8. Reinstall and Secure the Fill Cap:
    • Replace the fill cap and use a pair of pliers to lightly snug it down—KTM advises this step to keep it secure and avoid it coming loose unexpectedly.
  9. Check Oil Level (Optional):
    • If your model is equipped, check the oil level window to confirm the correct amount is inside after letting the engine rest for a minute.
  10. Dispose of Old Oil Properly:
    • Transfer used oil to a sealed container and take it to an approved recycling center. Never dispose of oil irresponsibly.

2013 KTM 150XC Model-Specific Tips

  • This model uses a magnetic drain plug—always clean it thoroughly to check for unusual metal particles.
  • Use a new crush washer each oil change to ensure proper sealing; skipping this step is a common source of leaks.
  • The specified torque for the drain plug is 20 Nm (14.8 ft-lbs). Overtightening could damage the engine case.
  • Oil capacity is 0.8 liters—do not overfill, as excess oil can lead to poor clutch performance.
  • If a skid plate is fitted, removal may simplify oil changes. If you prefer not to remove it, consider an aftermarket device or makeshift channel to direct oil past the plate and avoid mess.
  • Always use an oil recommended by KTM to match the requirements of the 150XC’s clutch and transmission.

After the Oil Change

  • Start the engine and let it idle for a few minutes. Check for leaks at the drain plug and fill cap.
  • Turn off the engine and recheck oil level if equipped with a sight window.

Note: For the 2013 KTM 150XC, you are changing the gear/transmission oil, not engine oil (it is a two-stroke). Always refer to your owner’s manual for specific recommendations and double-check specifications if your bike is modified or in case of unusual wear.
