Regular oil changes are essential to keep your 2013 Honda CRF150F running at peak performance and ensure long engine life. Follow this robust, step-by-step guide created exclusively for MotoSport.com for a DIY oil change designed specifically for your model.

Tools and Supplies Needed

  • 10W-30 motorcycle oil (Honda recommends a little more than 1 quart)
  • 24mm socket (for drain bolt)
  • Socket wrench
  • Torque wrench (capable of 11 ft-lbs/15 N·m)
  • Oil catch pan
  • Aluminum foil (optional for keeping frame clean)
  • Rags or paper towels
  • New sealing washer for drain bolt (recommended but not required every time)
  • Funnel
  • Phillips screwdriver (for removing skid plate)
  • Gloves (optional for cleanliness)

Steps to Change the Oil

  1. Warm up the engine.
    Start your Honda CRF150F and let it idle for 3–5 minutes. This thins the oil, ensuring it drains completely.
  2. Turn off the bike and secure it.
    Turn off the ignition and make sure your bike is upright and stable, using a stand if needed.
  3. Remove the skid plate (if installed).
    Use a Phillips screwdriver to remove the screws holding the skid plate and set it aside

    .
  4. Locate the drain bolt.
    The drain bolt is on the bottom of the engine. Place the oil catch pan directly beneath it.
  5. Remove the oil fill cap/dipstick.
    The fill cap is behind the kick starter on the right side. Removing it allows the oil to drain faster

    .
  6. Drain the oil.
    Use a 24mm socket and wrench to loosen the drain bolt. Carefully remove it and let the used oil drain into the catch pan. This is a good time to wrap some aluminum foil on the frame nearby to prevent drips or splashes

    .
  7. Inspect and clean the mesh oil screen.
    The 2013 CRF150F uses a reusable mesh oil screen, not a traditional filter. Remove it as the oil drains, rinse it with clean oil or petroleum solvent, and reinstall after drying. This is different from the CRF150R, which uses a replaceable filter

    .
  8. Inspect the drain bolt and sealing washer.
    Check for metal shavings on the bolt and replace the sealing washer if damaged or flattened.
  9. Reinstall the drain bolt.
    Thread the bolt by hand, then torque it to 11 foot-pounds (15 N·m) to avoid stripping threads

    .
  10. Pour in new oil.
    Add a little more than a quart of 10W-30 motorcycle oil using a funnel. Pour slowly to avoid spills. Do not overfill.
  11. Check oil level.
    To correctly check the oil level, insert the dipstick without screwing it in, then remove it and check the mark. Top off if necessary

    .
  12. Reattach the oil fill cap/dipstick.
    Securely reinstall the cap and wipe off any spilled oil.
  13. Reinstall the skid plate.
  14. Start the engine and inspect for leaks.
    Run the bike for a minute, turn it off, and check for leaks at the drain bolt and fill cap.
  15. Final oil check.
    Let the engine sit for a minute, check the oil on a level surface, and adjust if needed

    .
  16. Dispose of oil properly.
    Take used oil to a recycling facility or auto parts store that accepts waste oil.

CRF150F-Specific Call-Outs

  • The 2013 CRF150F uses a mesh oil screen you clean and reuse—there is no disposable filter.
  • Always use a 24mm socket for the drain bolt; this size is common for other maintenance tasks on this model

    .
  • When checking oil, do not screw the dipstick in—just insert it to get a proper reading

    .
  • Torque the drain bolt to 11 ft-lbs (15 N·m)—over-tightening can strip the threads on the crankcase, leading to costly repairs

    .
  • Use 10W-30 motorcycle oil, and always verify oil capacity in your owner's manual.
  • Always check for proper oil level on a level surface to avoid over or under-filling.

Additional Maintenance Tips

  • Change your oil every 10-15 hours of riding or as recommended by Honda in your service manual for best longevity.
  • If threads on the drain plug are stripped, do not ride—repair immediately.
  • Keep your work area clean to avoid debris entering the engine.
