Oil Type and Capacity Details for 2013 CRF150R Big Wheel

  • Engine side (with filter change): 590cc of oil
  • Engine side (without filter change): 560cc of oil
  • Clutch/Transmission side: 580cc of oil
  • Recommended oil: Honda GN4 10W-40 or equivalent

Oil Change Procedure

  1. Place oil drain pan beneath the engine.
  2. Remove engine oil fill cap/dipstick on top of the right-side engine cover for ventilation.
  3. Remove the engine oil drain bolt (10mm) on the bottom right of the engine. Let the old oil drain completely.
    • Replace the crush washer with a new one if worn to prevent leaks.
  4. (If replacing) Remove the oil filter cover bolts and oil filter cover. Take out the old filter.
    • Install the new oil filter and replace the O-ring if necessary.
    • Be careful when removing and installing bolts to avoid stripping threads.
  5. Reinstall and hand-tighten the engine drain bolt (torque to manufacturer spec if using a torque wrench).
  6. Repeat the process for clutch/transmission oil — the 2013 CRF150R uses separate engine and clutch/transmission oils.
    • Remove the clutch side drain bolt and drain the oil completely.
    • Replace the crush washer, then re-tighten the bolt.
  7. Using the funnel, pour new oil into each side:
    • Engine side: 590cc (or 560cc without filter change)
    • Clutch side: 580cc
    • Pour slowly to avoid overfilling and spills.
  8. Check oil levels:
    • Insert and remove the dipstick; the engine oil should be between the upper and lower marks (bike upright, not on stand).
  9. Reinstall oil fill caps securely.
  10. Start the engine and let it idle for several minutes.
    • Shut off, let the bike sit for a few minutes, then re-check oil levels on both sides and top off if necessary.
  11. Dispose of old oil and filter in accordance with local environmental regulations.

Model-Specific Call-Outs for 2013 Honda CRF150R Big Wheel Owners

  • Separate engine and clutch oil: The CRF150R uses two separate oil compartments—be sure to drain and fill both sides as noted above.
  • Crush washers are critical: Always replace both engine and clutch side crush washers to avoid leaks and possible engine damage.
  • Be gentle with drain bolts: The 2013 CRF150R cases are aluminum and prone to thread stripping if over-tightened. Use a torque wrench where possible and tighten to spec.
  • Start-up check: After completing the oil change, always check for leaks at the drain plugs and installation points, and re-verify oil levels after the first heat cycle.
  • Use only quality oil filters: For this engine's high performance, stick to OEM or high-quality equivalent oil filters to avoid oil pressure problems.
