Maintaining your 2023 Honda CRF250F is essential for performance and longevity. One of the most important routine services is changing the engine oil. This guide covers everything you need to know, including recommended tools, step-by-step instructions, and key model-specific notes.

Tools and Supplies Needed

  • 12mm socket and ratchet – For the oil drain bolt
  • 8mm socket – For the oil filter cover bolts
  • Torque wrench – For accurate reinstallation (set to 18 ft-lbs for drain bolt)
  • Oil drain pan
  • New crush washer (Honda part number recommended, replace every change)
  • New oil filter (Honda 15412-HM5-A10)
  • High-quality 4-stroke engine oil (Honda GN4 or equivalent; 1.7 quarts required)
  • Shop towels and gloves
  • Puppy pad or absorbent mat (optional, to catch spills)
  • Phillips screwdriver (if needed for skid plate removal)

Pre-Service Prep

  • Ride the bike gently or let it idle for 3-5 minutes to warm the oil. This helps it drain more completely.
  • Turn off engine and let the bike sit for about 2-3 minutes so the oil settles

    .
  • Place the bike on a stand or level ground for stability.

Step-by-Step Instructions

  1. Remove the Oil Fill Cap
    • Unscrew the fill cap on the right side to allow oil to drain smoothly.
  2. Drain the Old Oil
    • Place your drain pan under the engine drain bolt, located at the center underside of the engine.
    • Use a 12mm socket to remove the drain bolt.
    • Allow oil to completely drain; gently rock the bike for complete drainage

      .
  3. Replace the Crush Washer
    • Always install a new crush washer on the drain bolt. This prevents leaks and is highly recommended for every oil change.
  4. Reinstall the Drain Bolt
    • Thread the drain bolt by hand to avoid cross-threading.
    • Use a torque wrench to tighten to 18 ft-lbs as per Honda specification

      .
  5. Replace the Oil Filter
    • Remove the three 8mm bolts holding the oil filter cover on the right side of the engine.
    • Carefully pull the cover; expect a little oil spillage.
    • Note the orientation: the filter’s spring end faces toward the engine. Some filters have "spring side toward engine" marked on them for reference

      .
    • Clean the filter cavity and install the new filter with the correct orientation.
    • Reinstall the oil filter cover and tighten bolts evenly.
  6. Add New Oil
    • With the drain plug tight and the filter installed, pour in 1.7 quarts of 4-stroke engine oil. Use a funnel to avoid spills

      .
    • Reinstall the fill cap.
  7. Check Oil Level
    • Start the engine and let it idle for a minute to circulate oil.
    • Turn off the engine, wait several minutes, then check the dipstick or oil inspection window. Oil should be between the "min" and "max" marks.
    • If needed, add oil in small amounts until the level is correct. Avoid overfilling.
  8. Dispose of Old Oil Responsibly
    • Take used oil and filter to a recycling facility or auto parts store with hazardous waste collection.

2023 Honda CRF250F Model-Specific Notes and Call-Outs

  • The 2019–2023 CRF250F models share the same engine and oil system design; this procedure applies across these years with no substantive changes

    .
  • Always use a new crush washer; skipping this step is a common source of slow leaks.
  • Oil filter installation orientation is critical. The spring end of the filter faces the engine. Look for markings on the filter for guidance

    .
  • If you ride in heavy mud, water, or dust, increase oil change frequency for best engine health.
  • Oil capacity may be slightly less if not all oil can be drained out. Never force or overfill—check with the dipstick.

Pro Tips for Best Results

  • Keep extra crush washers and filters on hand to avoid delays.
  • Clean the area around the oil fill and filter before opening to prevent contamination.
  • Tighten all bolts by hand first, then finish with your torque wrench.
