Regular oil changes are essential to keep your 2007 Honda CRF50F running at peak performance.

Written exclusively for MotoSport.com, this is your definitive owner’s guide to changing your CRF50F’s oil.

Tools and Materials Needed

  • Socket wrench
  • 17mm socket (for oil drain bolt)
  • Oil drain pan
  • Clean funnel
  • Rags or paper towels
  • Fresh engine oil (Honda recommends 10W-40 for most environments, but consult the manual for regional recommendations)
  • New sealing washer for the drain bolt
  • Torque wrench (recommended)
  • Gloves

Preparation

  • Let your CRF50F’s engine warm up for a few minutes. Warm oil will flow out more easily and carry contaminants with it.
  • Ensure the bike is upright on a level surface. Use a stand if available.

Step-by-Step Oil Change Process

  1. Turn off the engine and let it sit for 2–3 minutes to allow the oil to settle.
  2. Place a drain pan underneath the engine.
  3. Remove the oil filler cap/dipstick to allow air in and make draining smoother.
  4. Using a socket wrench and 17mm socket, loosen and remove the oil drain bolt located at the lower right side of the engine.
    Important: Do not remove the cam chain tensioner push rod bolt (located nearby and similar-looking).
    Model-Specific Call-Out: The drain bolt is on the right side; the cam chain tensioner bolt is above it and must remain undisturbed. If removed by mistake, consult your dealer immediately for reinstallation instructions.
  5. Allow the oil to drain completely. Gently tilt the bike from side to side to ensure thorough drainage.
  6. Replace the old sealing washer on the drain bolt with a new washer (prevents leaks and ensures a tight seal).
  7. Reinstall the drain bolt and tighten to 18 lbf·ft (24 N·m, 2.5 kgf·m) using a torque wrench for accuracy.
  8. Place a clean funnel into the filler hole and add fresh oil. The correct amount is 0.6 US quarts (approximately 600 ml). Some oil may remain even with a thorough drain; fill until the oil level is correct on the dipstick and do not overfill.
  9. Reinstall and secure the dipstick/filler cap.
  10. Start the engine and let it idle for 3–5 minutes. Shut it off and let it settle for a few moments.
  11. With the bike held upright, check the oil level on the dipstick. If below the upper mark, add oil in small increments, checking frequently until the correct level is reached.
  12. Inspect for leaks at the drain bolt and around the oil filter cap.

Pro Tips and Model-Specific Notes

  • Be precise with the oil volume, since overfilling can damage seals or cause smoking. It’s normal for the required volume to vary slightly depending on how thoroughly you drained the old oil—use the dipstick, not just volume, as your ultimate guide.
  • When checking oil level, make sure the bike is absolutely vertical, not leaning on the stand.
  • If possible, consider upgrading to a drain bolt with a magnetic tip. This helps collect metal shavings and can extend engine longevity.
  • Tighten bolts gently: Stripping the aluminum threads on the engine can be expensive to repair.
  • Wash hands and clean up any excess oil from the engine after completion.
  • Dispose of used oil properly at a designated recycling center—never pour it down a drain or onto the ground.

Oil Selection Guide

  • Honda recommends 10W-40 oil for most temperature ranges. Synthetic or semi-synthetic blends like Maxima SynBlend are popular among CRF50F owners for enhanced protection, but always consult your owner’s manual if you ride in extreme environments.
  • Other viscosities may be used if temperature ranges are outside normal, but follow the manual’s chart for best performance and engine protection.

Routine Maintenance Schedule

  • Change the oil every 6 months or after every 600 miles of riding, whichever comes first. For riders in harsh or dusty conditions, more frequent changes are recommended.

Common Mistakes to Avoid

  • Overfilling or underfilling oil can cause damage. Always double-check with the dipstick and rely on proper orientation when checking.
  • Confusing the drain bolt with the cam chain tensioner push rod bolt can lead to major engine problems. Double-check bolt location before removal.
  • Reusing the sealing washer risks oil leaks—use a new one each time.

Conclusion

Changing the oil on your 2007 Honda CRF50F is simple and quick when done with care. By following this method, you ensure reliable engine performance, longevity, and more fun rides on the trails—all thanks to proper maintenance from MotoSport.com.
