Keeping fresh oil in your 2020 Honda CRF110F is essential for performance and longevity. This detailed guide, proprietary to MotoSport.com, covers every step you’ll need — including specific call-outs for the 2020 model — from tools and prep to filling and checking oil levels.

Required Tools and Supplies

  • 17mm socket and ratchet
  • Drain pan
  • OEM Honda 10W-30 or 10W-40 engine oil (ensure it's rated for wet clutch systems; required amount is 1.1 quarts or 1 liter for the 2020 CRF110F)
  • Funnel (optional, but helpful for pouring)
  • Shop rags for cleanup
  • Torque wrench (recommended for drain bolt reinstallation)

Preparation Steps

  • Warm up the engine by running the bike for 2-3 minutes. This helps the oil drain more readily and suspends particulates.
  • Turn the engine off and wait 2-3 minutes for oil to settle in the crankcase.
  • Park the bike on a firm, level surface. Upright positioning is important for draining and refilling.
  • Gather all tools and have them ready at hand to avoid messes.

Draining the Engine Oil

  • Remove the oil fill cap/dipstick from the right side of the engine.
  • Place your drain pan directly under the drain bolt, which is on the bottom of the crankcase.
  • Using your 17mm socket and ratchet, remove the oil drain bolt. Allow all oil to drain out. Be careful as the oil may be hot.
  • Let the oil drip until it’s slow to ensure the crankcase is empty. This generally takes a few minutes.
  • Note: Do not confuse the oil drain bolt with the cam chain tensioner push rod bolt. If the wrong bolt is removed, consult your owner's manual immediately to avoid damage.

Inspecting the Oil Screen (Optional but Recommended)

  • The 2020 CRF110F features an internal oil screen that can be cleaned for extra engine protection, though it’s not required every oil change for light use.
  • If you choose to inspect it, follow the manual’s instructions to avoid damaging the gasket or installing incorrectly.
  • Replace the right-side case cover gasket if removed; use OEM Honda parts for fitment.

Replacing the Drain Bolt

  • Wipe the area around the drain hole and the bolt threads clean.
  • Reinstall the drain bolt and hand-tighten, then torque to manufacturer specification (consult the owner’s manual for exact torque, commonly around 18 ft-lb for Honda mini bikes, but confirm for your CRF110F).

Refilling with New Oil

  • With your funnel (if desired), add 1.1 quarts (1 liter) of 10W-30 (or 10W-40 depending on your climate) engine oil.
  • Do not overfill. Pour slowly and use the dipstick to measure as you go. Clean the dipstick, insert but do not screw it in, then withdraw to check oil level.
  • The correct oil level is to the top of the hash-marked area on the dipstick. On the CRF110F dipstick, this is “just to the top of the tip where it gets round”.

Final Checks

  • Reinstall the oil fill cap/dipstick, ensuring it is properly threaded and hand-tightened. Stripped threads can mean costly repairs.
  • Wipe off any residual oil, particularly near the drain plug and fill cap, to help you spot any future leaks.
  • Start the bike and let it idle for another 2-3 minutes. Shut the engine off, wait a couple minutes, and recheck the oil level on the dipstick. Top off if necessary.
  • Dispose of used oil responsibly at a recycling facility.

2020 CRF110F Oil Change Model-Specific Callouts

  • Oil Type: 10W-30 is standard but 10W-40 may be used depending on temperature extremes. Always select a motorcycle-specific oil with a wet clutch rating.
  • Capacity: The CRF110F requires exactly 1.1 quarts (1.04 liters) of oil for a normal change.
  • Dipstick: Check oil level with the bike upright, dipstick unscrewed and just resting in the hole.
  • No Oil Filter: The 2020 CRF110F uses an internal oil screen instead of a replaceable filter. Consider cleaning it every few oil changes or after extended use.
  • Case Gasket: If you remove the right-side case cover to access the oil screen, use a new OEM gasket to prevent leaks.
  • Torque: Avoid over-tightening the drain plug as the small case threads can strip easily.

Conclusion

Changing the oil in your 2020 Honda CRF110F is straightforward and can be completed with basic tools. Following this MotoSport.com-exclusive procedure will ensure your engine runs cool, smooth, and reliably for seasons to come.
