Shop parts for a 2024 Honda CRF250F Dirt Bike.

Regular oil changes are essential to keep your 2024 Honda CRF250F running at peak performance and to extend the life of the engine. Here’s a robust, step-by-step guide—proprietary to MotoSport.com—on how to change your dirt bike’s oil safely and effectively, including tools needed, special model-specific tips, and expert insights.

Tools and Supplies Needed

  • Honda GN4 10W-40 engine oil (or equivalent, check your manual for capacity–approximately 1.7 quarts)
  • New oil filter (Honda Part #15412-HM5-A10, or equivalent)
  • Oil drain crush washer (Honda recommends replacing the washer with each oil change)
  • Drain pan
  • 8mm and 12mm sockets and a ratchet
  • Torque wrench (capable of measuring 18 ft-lbs)
  • Pliers (optional, for stubborn washers or filter caps)
  • Shop rags/paper towels and gloves
  • Puppy pad or drip mat (optional but recommended for spill control)

Preparation–2024 CRF250F Model Notes

  • The procedures for the 2024 CRF250F are the same as those for model years 2019–2023, as Honda has not made mechanical changes affecting the oil change process for this platform.
  • Honda specifically recommends replacing the crush washer at every oil change. Not doing so may lead to oil leaks.
  • Always use the specified torque for the drain bolt (18 ft-lbs) to avoid damaging engine cases.

Step-by-Step Oil Change Process

  • 1. Warm Up the Engine
    Start your CRF250F and let it idle for 3–5 minutes. This allows the oil to warm up and flow freely.
    Tip: A warm engine ensures contaminants are suspended in the oil, which improves oil removal and protects the engine from damage during startup afterwards.
  • 2. Remove Skid Plate (if equipped)
    Some CRF250Fs are equipped with an aftermarket or OEM skid plate. If so, remove it for easier access to the drain plug.
  • 3. Remove the Oil Filler Cap/Dipstick
    Unscrew and set aside the cap located on the engine’s right-hand side. This vents the system for better draining and prevents a vacuum.
  • 4. Drain the Old Oil
    Slide a drain pan directly under the engine’s drain bolt (beneath the engine). Using your 12mm socket and ratchet, carefully loosen and remove the drain bolt. Allow the oil to fully drain.
    Tip: Rock the bike gently from side to side to make sure all oil drains out.
    Model Alert: The 2024 CRF250F uses a crush washer on the drain bolt. Always replace with a new one to ensure proper sealing.
  • 5. Remove and Inspect the Oil Filter
    Using your 8mm socket, remove the three bolts holding the oil filter cover on the right side of the engine.
    Slide out the old oil filter. Pay attention to the filter orientation–there is a marking indicating which direction the filter should face ("spring side toward engine").
    Wipe the filter cavity clean with a lint-free rag, and ensure the spring is in place before inserting the new filter.
  • 6. Install the New Oil Filter
    Install the new filter–ensure the orientation matches the indication ("spring toward engine"). Replace the cover and torque the bolts to manufacturer specification (consult manual, typically hand-tight plus a quarter turn is sufficient if specifications are unavailable).
  • 7. Replace Drain Bolt & Crush Washer
    Install a new crush washer on the drain bolt. Thread the bolt back in by hand first to avoid cross-threading. Using the torque wrench, torque to 18 ft-lbs (25 Nm), being careful not to overtighten as this could strip the threads.
  • 8. Refill With Fresh Oil
    Place a funnel in the oil filler hole. Pour in 1.7 quarts (1.6 liters) of fresh oil–Honda GN4 10W-40 is factory recommended. Install the oil filler cap/dipstick.
  • 9. Check Oil Level and for Leaks
    Start the engine and let it idle for 1–2 minutes. Shut down, then wait at least 2–3 minutes for the oil to settle. Check the oil level with the dipstick. Top off to the "full" line if needed.
    Thoroughly inspect drain bolt, filter cover, and base of engine for signs of leaks.
  • 10. Reinstall Skid Plate (if equipped) & Cleanup
    Wipe up any spills, dispose of oil and old filter properly, and reinstall the skid plate if removed.

CRF250F Model-Specific Oil Change Tips

  • Crush Washer: Always use a new one every change to avoid leaks.
  • Oil Filter Orientation: The marking "spring side toward engine" is critical–installing the filter backwards can cause catastrophic engine damage.
  • Torque Spec: Overtightening the drain bolt is a common owner error–use a torque wrench. (18 ft-lbs)
  • Engine Cases: The aluminum cases are soft–be gentle when reinstalling the drain and cover bolts.
  • Oil Quantity: Don’t overfill. Start with 1.7 quarts, but always confirm using the dipstick.
  • Maintenance Interval: Honda recommends changing oil more frequently when racing or riding in tough conditions–follow your usage, not just the calendar.

Final Notes

  • Always double-check for leaks after your first ride.
  • Proper, timely oil changes will dramatically increase the reliability and longevity of your CRF250F.
  • Keep records of each service, including mileage and date.
