Tools and Materials Needed

  • 10mm and 8mm sockets or wrenches (for drain bolts and oil filter cover)

  • Replacement crush washer(s)
  • Measuring cup or graduated flask (to measure oil volume accurately)

Service Intervals and Oil Information

  • The oil should be changed every 6,000 kilometers (about 4,000 miles), or more frequently with hard/dusty riding conditions.
  • Always use premium four-stroke engine oil with 10W-40 viscosity and API SJ (or later) rating for optimal protection and performance.

  • Engine Oil Quantity:
    • With filter change: approximately 590 mL
    • Without filter change: approximately 560 mL
  • Transmission Oil (Separate): This model uses separate engine and transmission oil chambers. Be mindful not to mix them; follow your manual for transmission changes if needed.
  • Crush Washers: Replace the drain plug washers every service to prevent leaks.
  • Be gentle tightening the drain plug: Overtightening can strip the threads in the aluminum case.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start the motorcycle and let it run for a few minutes. This thins the oil, helping contaminants suspend and improving drainage.
    • Turn off the bike and let it cool just enough so you don't burn yourself.
  2. Prepare the Workspace
    • Position the bike upright (preferably on a stand) on a solid, level surface.
    • Set out your tools and drain pan beneath the engine's drain plug.
  3. Remove the Engine Oil Drain Plug
    • Use a 10mm socket or wrench to slowly remove the engine oil drain plug.
    • Allow all the oil to drain completely into the pan.
    • Inspect and replace the crush washer on the drain bolt if necessary.
  4. Change the Oil Filter (if required)
    • If changing the oil filter, remove the oil filter cover using an 8mm socket.
    • Carefully pull out the old oil filter and O-ring (replace the O-ring if worn or damaged).
    • Install the new oil filter (ensure it is oriented the same way as the old one), and press in a new O-ring lightly coated in oil.
    • Reinstall the oil filter cover and tighten the bolts securely but do not over-tighten.
  5. Reinstall the Drain Plug
    • Once oil stops dripping, clean the area and reinstall the drain plug with a new crush washer.
    • Tighten securely (spec: typically around 18 Nm, check your service manual), being careful not to over-tighten.
  6. Add New Engine Oil
    • Remove the oil fill cap/dipstick.
    • Using a funnel, pour in 590 mL (if filter is changed) or 560 mL (if not changing filter) of 10W-40 4-stroke motorcycle oil.
    • Replace the oil fill cap/dipstick.
  7. Check Oil Level
    • Start the engine and run it for about 30 seconds. Turn it off and let it settle for a minute.
    • With the bike upright, remove the dipstick, clean it, insert but do not screw it in, then check the oil level. Add oil if needed.
  8. Inspect for Leaks and Clean Up
    • Double-check the drain plug and oil filter cover for leaks as the engine runs.
    • Dispose of the used oil and filter at a certified recycling location.

Model Tips and Warnings

  • The CRF150R features separate oil chambers for engine and transmission; ensure you change only the correct chamber's oil.
  • Use a funnel and pour oil slowly to avoid overfilling. Spills can affect the clutch's performance.
  • Check the O-rings and washers each change. Worn seals can cause persistent leaks or pressure loss.
  • Do not mix oil brands/weights unless required in an emergency; consistent quality enhances engine life.

Final Notes

  • Always reference your owner's manual for torque specifications and recommended oils.
  • Test ride for a few minutes, then recheck the oil level–top off if necessary.
  • Maintain a log of oil changes to help with long-term maintenance and resale value.

Keeping your 2012 Honda CRF150R maintained with regular oil changes will enhance its lifespan and performance on the track or trail. For race-proven parts, gear, and more expert guides, MotoSport.com has you covered.
