  • Paddock stand or a way to keep the bike fully upright and secure

Oil and Filter Specs for 2019 Yamaha XT250

  • Oil capacity (with filter change): 1.37 quarts (1.3 liters)
  • Oil capacity (without filter change): 1.27 quarts (1.2 liters)
  • Oil Drain Bolt Torque: 15 ft-lb
  • Oil Filter Cover Bolts Torque: 7.2 ft-lb
  • Check oil level via sight glass on right engine case

Preparation

  • Warm the engine for 2–3 minutes to thin the oil. Do not run it long enough to get too hot.
  • Turn off the engine and secure your XT250 upright using a paddock stand or by balancing carefully. A level bike is required to accurately check the oil.

Step-by-Step Oil Change Instructions

  1. Remove the Engine Oil Drain Bolt
    • Place your drain pan under the engine’s drain bolt, located on the bottom left side.
    • Using a 12mm socket, loosen and remove the bolt. Replace the old crush washer with a new one to prevent leaks.
    • Allow all oil to fully drain—this can take several minutes.
  2. Remove and Replace the Oil Filter
    • Locate the oil filter cover on the lower right side of the engine.
    • Use a 10mm socket to loosen the three bolts and remove the cover. Note: The long screw goes in the top right, short in the top left—keep track of bolt positions.
    • Remove the old oil filter and install the new filter, matching orientation.
    • Reinstall the cover. Hand-tighten the bolts, then torque each to 7.2 ft-lb.
  3. Install the Drain Bolt
    • Wipe the threads; install the drain bolt with its new crush washer.
    • Torque the drain bolt to 15 ft-lb. Over-tightening may strip the threads or crack the case.
  4. Add New Engine Oil
    • Remove the oil fill cap on the right side of the engine.
    • Using a funnel, add 1.37 quarts (1.3 liters) of 10W-40 motorcycle oil if you replaced the oil filter. If not, add only 1.27 quarts (1.2 liters).
    • Pause periodically and check the oil sight glass (with the bike upright) to avoid overfilling.
  5. Warm the Bike and Check the Oil Level
    • Reinstall the fill cap, start the engine, and let it idle for several minutes.
    • Shut off the engine and allow the oil to settle for about a minute.
    • With the bike level, check the oil sight glass—the level should be between the marks.
    • Add more oil if needed, pouring slowly and checking often.

XT250-Specific Notes & Call-Outs

  • Oil Drain Bolt Location: Bottom left of the engine case—ensure it’s fully removed for proper draining.
  • Oil Level Checking: Always with the bike level. If you lack a paddock stand, ask a friend to help balance the bike while you check the sight glass.
  • Bolt Orientation: Oil filter cover bolts are different lengths. Keep track of each and don’t swap them, as misplacement may cause leaks or damage.
  • Crush Washer: Always use a new crush washer on the drain bolt for a proper seal.
  • Final Oil Level: After replacing the filter, the new oil filter will absorb oil. Let the engine run briefly, shut off, wait a minute, then check and top off as needed.
  • Recommended Oil: Yamaha recommends Yamalube 10W-40 for optimal engine and clutch performance.

Waste Oil Disposal

  • Pour used oil into a sealable container and take it to your local recycling center or auto shop that accepts waste oil.

Conclusion

With routine oil changes using high-quality oil and a fresh filter, your Yamaha XT250’s air-cooled engine will remain reliable for every adventure.
