Shop parts for a 2013 Yamaha XT250 Dirt Bike.

Proper oil changes are essential for your Yamaha XT250's performance and engine longevity. This dirt bike, known for its reliability and versatility, benefits greatly from regular oil maintenance. Follow this comprehensive oil change guide made proprietary for MotoSport.com to ensure you service your 2013 Yamaha XT250 correctly and safely.

Tools and Supplies Needed

  • Metric socket set (notably 12mm and/or 14mm for drain bolt and oil filter cover bolts; verify on your bike as bolts can differ)
  • Torque wrench (for proper bolt tightening)
  • New oil filter (specific to Yamaha XT250)
  • Fresh engine oil (Yamalube 10W-40 or equivalent, 1.27 quarts if not replacing filter, 1.37 quarts if replacing filter)
  • Oil drain pan
  • Rags or shop towels
  • New crush washer for drain bolt
  • Funnel
  • Gloves (optional, for cleanliness)
  • Stand or something stable to keep bike upright and level

Steps to Change the Oil

  1. Warm Up the Bike
    Start the engine and let it idle for about 3–5 minutes. This warms the oil, making it drain more fully.
  2. Secure the Bike
    Place the XT250 on a stable stand or have a helper keep it upright and level. This ensures accurate oil draining and proper oil level checking later.
    Model Note: The oil level must be checked with the bike level, not on the sidestand.
  3. Remove the Skid Plate (if equipped)
    If your XT250 has a skid plate, remove it using the appropriate sockets to access the drain bolt.
  4. Drain the Old Oil
    Position the drain pan directly beneath the drain bolt (bottom of engine, left side).
    Using the correct socket (typically 12mm on 2013 models), loosen and remove the drain bolt. Allow oil to fully drain.
    Discard the old crush washer; you'll use a new one during reassembly.
  5. Remove and Replace the Oil Filter
    The oil filter cover is on the left side of the engine. Remove its bolts (note bolt lengths and positions — the longer bolt goes in top right, shorter in top left for the XT250).
    Remove the old filter and replace with a new one, matching its orientation.
    Lightly oil the new filter's O-ring with fresh oil.
    Reinstall the oil filter cover, torquing the bolts to 7.2 ft-lbs.
    Model Specific: The XT250 oil filter cover bolts are of different lengths; do not mix them up. Long bolt: top right, short bolt: top left.
  6. Reinstall the Drain Bolt
    Wipe any debris or oil from the drain surround and reinstall the drain bolt with a new crush washer. Torque to 15 ft-lbs.
  7. Add New Oil
    • If you replaced the oil filter, add 1.37 quarts (1.3 L)
    • If you did not replace the filter, add 1.27 quarts (1.2 L)
    Use a funnel to prevent spills. Pour oil slowly and check the level as you approach the full amount. Always use oil suitable for motorcycle wet clutches.
  8. Check the Oil Level
    Start the engine for 30–60 seconds to circulate oil, then shut it off. Allow the bike to sit for a minute so oil settles.
    With the bike upright and level, check the sight glass: oil should be between the upper and lower marks. If needed, add small amounts of oil and repeat until the correct level is reached.
    After changing the filter, you'll likely need to top up after the engine runs, as the filter will absorb some oil.
  9. Reinstall Skid Plate (if removed) & Clean Up
    Replace the skid plate and ensure all tools are accounted for and the area is clean.
  10. Final Check
    Inspect for any leaks around the oil filter cover and drain plug. Confirm the oil level after a short ride and adjust if necessary.

Pro Tips and Model-Specific Callouts for the 2013 XT250

  • Filter Bolt Lengths: Always install the correct screws in their original locations for the oil filter cover—incorrect lengths may cause leaks or damage.
  • Torque Specs: Do not overtighten the filter cover or drain bolt; use a torque wrench to avoid stripping threads (7.2 ft-lbs oil filter cover, 15 ft-lbs oil drain bolt).
  • Oil Amount: Be precise—overfilling may cause engine problems; too little oil can harm your engine. Add in stages, using the sight glass.
  • Check O-Rings: Inspect O-rings for damage or wear when changing the filter; replace if necessary.
  • Crush Washer: Always use a new crush washer on the drain bolt for a tight seal and leak prevention.
  • Level Surface: Make sure the bike is perfectly upright when checking oil level; the reading will not be accurate on the sidestand.
