Shop parts for a 2020 Yamaha XT250 Dirt Bike.

If you own a 2020 Yamaha XT250, regular oil changes are crucial to keep your engine running smoothly and efficiently. The Yamaha XT250 is known for its reliable engine and durable design, but proper maintenance ensures long-term performance—so here's how you can quickly and confidently perform an oil change at home.

Tools and Supplies You Will Need

  • 10mm and 12mm socket or wrench (for filter cover and drain bolt)
  • Torque wrench (recommended for precise tightness)
  • Oil drain pan
  • Funnel
  • Clean rags or paper towels
  • Replacement oil filter (Yamaha OEM or equivalent)
  • New crush washer (for drain bolt)
  • Engine oil (Yamalube 10w-40 is recommended, but always double-check owner’s manual)
  • Gloves (optional, for cleanliness)

Oil and Filter Specs for the 2020 Yamaha XT250

  • Oil quantity w/ filter change: 1.37 quarts (1.3 L)
  • Oil quantity w/o filter change: 1.27 quarts (1.2 L)
  • Oil filter orientation: Pay close attention to the direction—flat side faces outward; incorrect installation can damage your engine
  • Drain bolt torque: 15 ft-lb (20 Nm)
  • Oil filter cover bolts torque: 7.2 ft-lb

Model-specific call-out: The 2020 Yamaha XT250 uses a simple sight glass for checking the oil level (not a dipstick), so ensure the bike is level when checking oil after filling and running the engine. Overfilling or underfilling can lead to engine damage, so be precise.

Step-by-Step Oil Change Instructions

  • 1. Warm Up the Engine
    • Start the engine and let it idle for about 3-5 minutes. This helps suspend contaminants and allows old oil to drain out more easily. Warm oil also flows out faster.
  • 2. Secure the Bike
    • Put the XT250 on its sidestand, or for the most accurate oil level check, carefully prop the bike up so it stands vertically (ask a friend for help if needed).
  • 3. Remove the Skid Plate (if installed)
    • Many XT250s are fitted with a skid plate. If yours has one, remove it for clear access to the drain bolt.
  • 4. Drain the Old Oil
    • Position the drain pan under the engine.
    • Use the 12mm socket to loosen and remove the oil drain bolt. Allow all oil to drain completely.
    • Replace the crush washer on the drain bolt if it is damaged or worn.
  • 5. Remove and Replace the Oil Filter
    • With a 10mm socket, remove the three bolts holding the oil filter cover. Note the length and position of each bolt; the top right bolt is longer than the others and must go back in the same spot .
    • Remove the old oil filter. Make sure the spring and O-ring are in place and not left inside or stuck to the cover. Wipe away any old oil and debris.
    • Lightly coat the new filter's O-ring with clean oil or waterproof grease for a good seal and easy installation, as recommended by experienced owners .
    • Install the new filter in the correct orientation (flat side out).
    • Replace the cover and bolts, hand-tightening first, then torque each to 7.2 ft-lb.
  • 6. Reinstall the Drain Bolt
    • Once the oil has fully drained, reinstall the drain bolt with its new crush washer and tighten to 15 ft-lb with a torque wrench .
    • Wipe off any spilled oil around the area.
  • 7. Add New Oil
    • Place a funnel in the oil filler cap on the right side of the engine.
    • Add 1.37 quarts (if you changed the filter) or 1.27 quarts (if you did not). Use only the recommended oil-type (Yamalube 10w-40 is preferred for the XT250) .
    • Replace the oil filler cap.
  • 8. Check for Leaks
    • Start the motorcycle and let it idle for several minutes. Carefully check around the filter cover and drain plug for any leaks. Shut off the engine.
  • 9. Check the Oil Level
    • After the engine is off for a minute, carefully stand the bike upright and check the oil level in the sight glass. The oil should be between the upper and lower marks .
    • Top off oil if necessary—do not overfill. Add oil in small increments if needed and recheck between each addition.
  • 10. Reinstall Skid Plate (if equipped)
    • Replace the skid plate if you removed it and torque the bolts to the specified values (refer to your owner’s manual).

Important Tips for the 2020 Yamaha XT250 Oil Change

  • Maintain the correct bolt orientation—the top right oil filter cover bolt is longer than the others and must be installed in the same position .
  • Always replace the drain plug's crush washer to ensure a leak-free seal.
  • Use only motorcycle-specific oil. Automotive oils with friction modifiers can damage the wet clutch system .
  • Always double-check the oil level with the bike fully upright for an accurate reading .
  • Change the oil at regular intervals—Yamaha recommends the first oil change at 1,000 km (600 miles), then at recommended service intervals thereafter .

Conclusion

Changing the oil in your 2020 Yamaha XT250 is straightforward with the right tools, some patience, and a bit of attention to detail.
