Your Yamaha XT250 deserves the best care to keep its engine running strong, and one of the simplest ways to ensure its longevity is a regular oil change. Follow this MotoSport.com exclusive guide—complete with required tools, step-by-step instructions, and XT250-specific tips—to perform an oil change on your 2014 model.

Tools and Materials Needed

• Socket wrench with appropriate sockets (commonly 17mm and 8mm)
• Oil drain pan
• Funnel
• New engine oil: Yamaha recommends 10W-40, but always refer to your owner’s manual for local temperature adjustments (use a motorcycle-specific oil for wet clutches)
• New oil filter (optional but recommended with every oil change)
• New crush washer for the drain bolt
• Clean rags for cleaning up spills
• Torque wrench (capable of measuring up to 15 ft-lb)
• Gloves to protect your hands
• Bottle or measuring cup to ensure correct oil volume
• Stand or assistant to hold the bike upright

Preparation Steps

• Start the engine and let it idle for a few minutes—this warms and thins the oil, making it easier to drain.
• Turn off the engine and ensure the bike is secure and upright. Use a stand or ask someone to help hold the bike steady, ensuring it’s level for draining and filling (the oil sight glass is calibrated for level checking when the bike is upright).

Step-by-Step Oil Change Process

• Remove the Oil Drain Bolt
  • Place the drain pan underneath the engine.
  • Locate the oil drain bolt beneath the engine and remove it with a socket wrench.
  • Allow all old oil to fully drain out.
  • Remove and replace the crush washer to prevent leaks when reinstalling the drain bolt.
• Replace the Oil Filter (if performing a filter change)
  • Locate and remove the three bolts holding the oil filter cover (use an 8mm socket).
  • Replace the old filter with a new one. Make sure you install the filter in the correct orientation: the rubber side faces the engine.
  • Reinstall the filter cover: the long screw goes in the top right hole, the short screw in the top left. Hand-tighten all screws, then torque each to 7.2 ft-lb for proper sealing.
  • Wipe the area clean of excess oil.
• Reinstall the Oil Drain Bolt
  • After all the oil has drained and the new crush washer is in place, reinstall the drain bolt.
  • Tighten it first by hand, then use a torque wrench to tighten it to 15 ft-lb.
  • Don’t overtighten—the oil pan threads can strip if excessive force is used.
• Add Fresh Oil
  • Remove the oil fill cap on the top of the engine.
  • Insert a funnel and pour in new 10W-40 oil.
  • For a 2014 XT250:
    • If you changed the filter, add 1.37 quarts (1.3 liters).
    • If not replacing the filter, add 1.27 quarts (1.2 liters).
  • Fill slowly, periodically checking the sight glass on the right side of the engine. With the bike upright and level, the oil should reach about halfway up the sight glass (between upper and lower marks).
  • Do not overfill. Overfilling can cause excess pressure and oil leaks.
• Check for Leaks and Final Oil Level
  • Reinstall the fill cap and start the engine.
  • Let it idle for 2–3 minutes, then turn it off and wait another minute for oil to settle.
  • While the bike is upright, check the sight glass. Add oil if needed until it’s between the upper and lower marks.
  • Check for leaks around the drain bolt and filter cover.

Specific 2014 Yamaha XT250 Owner Call-Outs

• Sight Glass Placement: Always check the oil level with the motorcycle standing upright and level. Using the kickstand will give an inaccurate (lower) reading. If you can’t hold the bike upright by yourself, ask for help or use a proper motorcycle stand for safety.
• Torque Values: Do not exceed the listed torque specs—7.2 ft-lb for oil filter cover screws and 15 ft-lb for the drain bolt. Stripping threads in the aluminum cases is a costly mistake.
• Oil Choice: Always use JASO MA/MA2 rated motorcycle oil—regular automotive oils with energy-conserving (friction-reducing) additives can damage clutch performance.
• Crush Washer: Replace the crush washer at every oil change to ensure a proper seal.
• Warm Engine First: Changing oil after running the engine ensures better drainage by thinning the oil and moving suspended contaminants near the drain.

Disposal and Final Tips

• Dispose of your used oil and filter at a certified recycling station; never pour oil down the drain or on the ground.
• Write down the date and mileage of your oil change for future reference and warranty claims.
• Inspect oil for metallic flakes—if found, it may indicate excessive engine wear.
• Inspect your drain bolt and surrounding area for oil leakage after your first ride post oil change.
