Shop parts for a 2017 Honda CRF150F Dirt Bike.

Changing the oil in your 2017 Honda CRF150F is a vital part of routine maintenance. Regular oil changes ensure your dirt bike runs smoothly, delivering optimal performance and engine longevity. This comprehensive MotoSport.com guide provides all steps, tools, and key model-specific notes you'll need for a robust and efficient oil change.

Tools and Supplies Needed

  • 10mm and 12mm socket and ratchet (for bolts and drain plug)
  • Oil drain pan (to collect used oil)
  • Funnel (to pour new oil safely)
  • Clean rag or paper towels (for cleaning spills and checking the dipstick)
  • New engine oil (Honda GN4 10W-30 or quality equivalent, approx. 1.1 US quarts/1.04 liters)
  • Replacement crush washer (recommended for the drain plug)
  • Torque wrench (to ensure correct tightness on drain bolt)
  • Optional: Skid plate removal tool (if your bike's plate covers the drain bolt)
  • Foil or splash shield (to protect the frame from oil drips)

Preparation and Safety

  • Ride the bike for a few minutes to warm the engine slightly; warm oil drains faster and carries away more contaminants.
  • Turn off the engine and support your bike upright on a firm, level surface using a stand.
  • Allow the engine to cool until just warm to the touch.

Step-by-Step Oil Change Procedure

  1. Remove the Skid Plate (if equipped):
    • Use the appropriate socket to remove the skid plate for easier access to the drain plug.
      Tip: Some CRF150Fs require the plate removal for cleaner access, especially if there is a risk of oil splash.
  2. Locate the Drain Plug:
    • Find the drain bolt under the engine, just below the crankcase.
      Protect your frame using a piece of foil or a splash shield to guide the oil cleanly into the pan.
  3. Drain the Old Oil:
    • With your drain pan ready, use a 12mm socket to carefully remove the drain plug. Allow all the oil to drain fully.
    • Clean the drain plug, check for metal debris, and replace the crush washer if necessary to prevent leaks.
    • Inspect the threads; DO NOT over-tighten when reinstalling to avoid stripping.
      Note: Torque the drain plug to 11 ft-lbs (15 Nm) as recommended for this model.
  4. Clean the Oil Screen (if equipped):
    • The CRF150F typically uses a reusable mesh oil screen instead of a spin-on filter.
      Carefully remove and clean the mesh screen in solvent, then reinstall it if your particular year has this feature.
  5. Reinstall the Drain Plug:
    • Screw in the drain plug by hand, then torque to spec (11 ft-lbs/15 Nm).
    • Do not overtighten; aluminum cases are soft and the threads can strip easily.
  6. Add New Engine Oil:
    • Locate the oil filler cap on the right side, behind (or near) the kickstarter.
    • Remove the dipstick/oil filler cap and slowly add fresh oil, using a funnel to avoid spilling.
    • For a 2017 CRF150F, add about 1.1 US quarts (1.04 liters) of 10W-30 motorcycle oil.
      Do not overfill. Add in increments and check the level.
  7. Check Oil Level:
    • With the bike upright on level ground, insert (but do not screw in) the clean dipstick, remove, and check the reading. Oil should be between the upper and lower marks.
      Do not screw the dipstick in for the check–just insert and withdraw to read the level.
    • If needed, add a small amount of oil to reach the upper mark, but do not exceed it.
      Overfilling can cause pressure issues; underfilling can cause engine damage.
  8. Run and Re-check:
    • Reinstall the dipstick and run the engine for a minute to circulate oil, then shut off and wait a few minutes.
    • Re-check the oil level as above and top-off if necessary.
  9. Reinstall Skid Plate:
    • Reattach the skid plate if you removed it. Tighten bolts to secure but do not overtighten.
  10. Clean Up and Final Inspection:
    • Wipe away spills, check for leaks around the drain plug and oil fill cap.
    • Properly dispose of old oil at a local recycling center.

Model-Specific Call-outs for the 2017 Honda CRF150F

  • No paper oil filter: The CRF150F uses a mesh filter/screen that is cleaned and reused.
  • Oil Capacity: Approximately 1.1 US quarts (check manual for variations).
  • Dipstick checking: The oil level should always be checked with the bike upright and the dipstick inserted but not screwed in; screwing it in gives inaccurate readings

    .
  • Crush washer: Always replace or inspect the drain plug crush washer. Reuse can lead to drips or leaks.
  • Thread care: The oil drain bolt is prone to stripping if overtightened. Always use a torque wrench if possible

    .
  • Recommended oil: Use Honda GN4 10W-30 or an equivalent JASO MA-rated motorcycle oil for best clutch and engine protection

    .

Pro Tips for Success

  • Refer to your owner's manual for exact torque values, oil types, and intervals.
  • If you lose track of oil level, drain and measure added oil to ensure correct capacity.
  • Keep a maintenance log with date, hours, and oil type for future reference and resale value.
