Regular oil changes are crucial for keeping your Honda CRF50F running smoothly and prolonging engine life. Below you'll find a detailed, step-by-step guide on how to change the oil in a 2023 Honda CRF50F, including all tools needed, important tips, and CRF50F-specific advice for MotoSport.com customers.

Tools and Materials You Will Need

  • 10W-30 motorcycle oil (approx. 0.6 US quarts – 600 ml)
  • 17mm socket and ratchet or box-end wrench
  • Oil drain pan (suitable for at least 1 quart of fluid)
  • New sealing washer for the drain bolt
  • Clean rags or paper towels
  • Funnel (optional, but recommended for spill prevention)
  • Torque wrench (optional, for precise tightening)
  • Gloves (optional, keeps hands cleaner)

Step-by-Step Oil Change Instructions for the 2023 Honda CRF50F

  1. Warm up the engine.
    • Start the CRF50F and let it idle for 3–5 minutes. This will thin the oil and help it drain more thoroughly.
    • Turn off the engine and let the bike sit for 2–3 minutes to allow the oil to settle back into the crankcase.
  2. Stabilize the bike.
    • Park your CRF50F on a firm, level surface with the kickstand or a stand. Stability is important to avoid spills.
  3. Remove the oil fill cap/dipstick.
    • Unscrew and remove the oil fill cap/dipstick from the right side of the engine.
  4. Drain the old oil.
    • Place your oil drain pan underneath the crankcase.
    • Using a 17mm socket or wrench, unscrew the oil drain bolt (located on the bottom of the engine, directly facing downward).
    • Special call-out for the CRF50F: Do NOT remove the bolt angled toward the bike; this is the cam chain tensioner push rod bolt and removing it may cause internal parts to come loose and oil to leak inappropriately. Only remove the drain plug pointing straight down from the engine case.
    • Let the oil drain completely. You can gently tilt the bike side-to-side to ensure all oil is removed.
  5. Inspect and replace the sealing washer.
    • Remove the old sealing washer from the drain bolt and replace it with a new one. This step helps prevent leaks.
  6. Reinstall the drain bolt.
    • Reinstall the drain bolt with the new washer. Tighten it to 18 lbf·ft (24 Nm). If you don’t have a torque wrench, ensure it's snug but not overtightened to avoid stripping the threads.
  7. Add new engine oil.
    • Using a funnel, pour 0.6 US quarts (600 ml) of 10W-30 motorcycle oil into the oil fill hole.
    • Install the dipstick/oil cap loosely.
  8. Check the oil level.
    • Start the engine and let it idle for another 3–5 minutes, then shut it off and let it settle for 2–3 minutes.
    • With the bike upright (not on the kickstand), remove the dipstick, wipe it clean, and reinsert it without screwing it in. Remove the dipstick and verify that oil is at or near the upper level mark.
    • If needed, add oil until the proper level is reached, but be careful not to overfill.
  9. Final checks.
    • Install the dipstick/oil cap securely.
    • Start the bike and check for leaks at the drain bolt and oil filter area.
    • Dispose of used oil properly, never down the drain or into the ground (follow local recycling regulations).

Model-Specific Call-Outs for the 2023 CRF50F

  • Oil capacity: The 2023 CRF50F requires approximately 0.6 quarts (600 ml) of oil, but it's always best to fill to the dipstick’s “full” line rather than relying solely on the volume measurement because you may not remove every drop during draining. Always check the dipstick to ensure proper level.
  • Sealing washer: Always replace the sealing washer each time you change the oil to prevent leaks from the drain bolt.
  • Correct drain plug: The CRF50F shares its engine with XR50 models from 2000–present, and the layout is similar across these years. Only remove the downward-facing drain bolt; never remove the cam chain tensioner push rod bolt (angled toward the bike) — doing so can result in lost or damaged internal components and leaks.
  • Dipstick check: When checking oil level, set the dipstick IN the threads without screwing it in, and keep the bike upright — not leaned — for a proper reading.
  • Oil type: Use only high-quality motorcycle-specific 10W-30 oil, as recommended by Honda. Automotive oils may lack necessary additives for wet-clutch protection.

Why Regular Oil Changes Matter

  • Reduces engine wear by keeping internal parts lubricated
  • Prevents overheating and maintains optimal engine temperature
  • Removes contaminants and debris that accumulate with use
  • Increases overall longevity and performance of your CRF50F
