Honda CRF150R Oil Change Step-by-Step Guide

Preparation

  • Warm up the engine for 3–5 minutes to help the oil drain faster and completely.
  • Shut off the engine and put the bike on a stand or level surface.
  • Make sure the ignition is off and the bike is cool enough to handle safely.

Step 1: Remove the Engine Oil Drain Bolt

  • Locate the engine oil drain bolt (12mm) underneath the engine. Refer to your manual for the exact position if needed—it is distinct from the transmission drain bolt.
  • Position the drain pan beneath the bolt.
  • Use the 12mm wrench to remove the bolt and allow oil to drain completely.
  • Inspect and replace the crush washer if it is worn or damaged to prevent future leaks.

Step 2: Remove and Replace the Oil Filter (If Applicable)

  • Locate the oil filter cover on the engine side (check your owner’s manual for exact location).
  • Remove the bolts securing the cover with the appropriate socket.
  • Carefully remove the oil filter and O-ring.
  • Inspect the O-ring for nicks or deformation. Always replace a pinched or damaged O-ring to prevent oil leaks, a common issue on CRF150R if not carefully seated.
  • Install the new oil filter and ensure the O-ring is properly seated before replacing the cover.
  • Tighten the cover bolts to the specified torque.

Step 3: Remove the Transmission Oil Drain Bolt (If Changing Transmission Oil)

  • The transmission oil drain bolt (often 8mm) is separate and located on the other side of the engine.
  • Place your drain pan below this bolt and remove to drain the transmission oil completely.
  • Replace the drain bolt washer if necessary.
  • Reinstall and tighten the bolt to spec.

Step 4: Reinstall Drain Bolts

  • Check for debris on the bolts. Clean if needed.
  • Install new washers if required.
  • Reinstall and torque each drain bolt to the Honda-specified value (consult your owner’s manual for exact numbers).

Step 5: Add Fresh Engine Oil

  • Locate the engine oil fill cap (top of the right engine side cover).
  • For the 2022 CRF150R:
    • Oil quantity with filter replacement: 590–600 mL
    • Oil quantity without filter replacement: 550–560 mL
  • Insert a funnel and slowly pour in the correct amount of oil.
  • Use the dipstick to check the oil level; the bike should be upright and not leaning on a stand for an accurate reading.

Step 6: Add Transmission Oil (if applicable)

  • Locate the transmission fill bolt on the left side of the bike.
  • Add the correct spec and volume of transmission oil (600–650 mL, check your manual).
  • When the oil level stops rising and just begins to seep from the inspection hole, it's at the correct fill point.

Step 7: Final Checks and Cleanup

  • Inspect all bolts and caps for tightness.
  • Start your bike and let it idle for a minute. Watch for leaks at the drain bolts and oil filter cover.
  • Shut off the engine and re-check oil levels; top off if needed.
  • Dispose of used oil and filters responsibly at a recycling facility.

2022 Honda CRF150R Model-Specific Call-Outs

  • Dual drain bolts: This model features separate engine and transmission oil cavities; do not mix up the bolts or fill locations as improper filling can damage your engine/transmission.
  • O-ring care: Ensure the oil filter O-ring is seated correctly and not pinched; a pinched O-ring is a common source of oil leaks for CRF150R models.
  • Oil level accuracy: Upright positioning and careful dipstick measurement are critical on this bike due to its small oil volume.
  • Washer replacement: Always replace the drain bolt washers to maintain proper sealing and avoid leaks.

Tips for a Flawless Oil Change

  • Always use OEM-specified oil for best engine and transmission performance.
  • Track your maintenance in a log or app to ensure you follow Honda’s recommended schedule.
  • If you notice oil leaks after a change, re-check O-ring and washer placement, and confirm all bolts are correctly torqued.
