Regular oil changes are essential to keeping your 2023 Honda CRF110F running reliably and performing at its best. Riders of all skill levels can tackle this straightforward maintenance procedure with some basic tools and care. Below, we walk through each step and share crucial call-outs specific to this year's model.

Tools & Supplies Needed

  • 17 mm socket and ratchet (for stock drain plug)
  • Drain pan
  • Measuring cup or liter-marked oil jug
  • Fresh engine oil (Honda recommends 10W-30 for wet clutch, 1 liter)
  • New sealing (crush) washer
  • Towels/rags (for spills)
  • Funnel (optional, but helpful for pouring oil)
  • Torque wrench (if available, for accurate fitting)

Model-Specific Call-Outs for the 2023 Honda CRF110F

  • The crankcase takes exactly 1 liter of oil, as per Yamaha and verified by the owner’s manual and experienced tuners.
  • Use a new crush washer every oil change to prevent leaks.
  • This model does not use an oil filter, but it has an internal oil screen (check per manufacturer schedule, not every oil change).
  • Don’t confuse the oil drain bolt (17 mm head) with the cam chain tensioner bolt (see owner's manual illustration). Removing the wrong bolt can cause engine issues.
  • Do not overtighten the drain bolt—Honda specifies 20 ft/lbs (27 Nm) for reinstalling the drain bolt.

Step-By-Step: Changing the Oil

  1. Warm Up the Engine

    Start your CRF110F and let it idle for 3-5 minutes. This warms up the oil so it drains out more easily and removes debris.

  2. Prepare and Drain the Oil
    • Place your bike on a firm, level surface (use a stand if possible).
    • Turn off the engine and let it sit for 2-3 minutes to allow oil to settle in the sump.
    • Unscrew and remove the oil fill cap/dipstick (right side, mid-engine).
    • Set a drain pan under the crankcase, then remove the 17 mm oil drain bolt (under the right side of the engine).
    • Make sure to catch both the bolt and the crush washer; the washer may stick to the crankcase.
    • Briefly tilt the bike upright and side-to-side to drain all the old oil out.
  3. Install New Washer and Refit Drain Plug
    • Remove the old sealing (crush) washer and fit a new one to the oil drain bolt for leak-free sealing.
    • Screw the drain bolt back in and tighten with a torque wrench set to 20 ft/lbs (27 Nm) if you have one. Do not over-tighten; it can strip threads or crack the case.
    • If you’re upgrading, this bike also fits a magnetic drain plug size M12 x 1.5 mm (14 mm head socket for some aftermarket options).
  4. Add New Oil
    • Pour in exactly 1 liter (1.06 US qt) of 10W-30 oil rated for wet clutch motorcycles.
    • Use a funnel to avoid spills, or pour slowly from a small-mouthed bottle.
    • Reinstall the oil fill cap/dipstick.
  5. Warm and Check Oil Level
    • Start the engine and let it idle for another 3–5 minutes. This helps the new oil circulate completely.
    • Turn off the engine and wait briefly (1–3 minutes) for the oil to settle.
    • With the bike upright and level, remove the dipstick but do not screw it in: simply set it in the opening until the cap seats, then pull it out and check the oil level—it should be between the marks, ideally centered.
    • Add a little more oil if needed, being careful not to overfill.

Additional Tips

  • Dispose of used oil properly—never pour it outside; use a certified collection site.
  • If you're riding in severe conditions (dust, mud, high heat), consider changing the oil more frequently than the manual suggests.
  • If you also want to check or clean the internal oil screen, refer to the service manual—it’s not required every oil change, but worth doing periodically for long engine life.
  • Be sure to wipe any spilled oil off the case to prevent dirt buildup.

Common Questions from Owners

  • How often should I change the oil? Honda recommends every 600 miles or 6 months for recreational use, but many off-road riders change it more often to protect engine life.
  • Do I need to replace the crush washer every time? Yes, this inexpensive part prevents leaks—always install a new one.
  • Can I use synthetic oil? Yes, as long as it's the correct viscosity (10W-30) and formulated for wet clutch applications.
  • Do I need to check the torque? It's recommended—improper torque can cause leaks or damage.

With these simple steps and careful attention to detail, you can confidently change the oil in your 2023 Honda CRF110F and keep your riding fun, safe, and trouble-free.
