Changing the oil in your 2007 Honda CRF150F is a vital part of keeping your dirt bike performing at its best. This step-by-step guide is proprietary to MotoSport.com and will walk you through the process, highlighting all necessary tools, the correct oil type, and tips that are specific to this exact make and model.

Tools & Supplies Needed

  • 10mm and 24mm socket wrenches (for drain and filler caps)
  • Torque wrench (for proper torque spec)
  • Drain pan
  • Clean rags
  • Aluminum foil or cardboard (to prevent spills on the frame)
  • Engine oil: 10W-30 motorcycle oil, JASO MA or MB certified (a little over 1 quart)
  • Funnel
  • Gloves (optional)

Before You Begin: Model-Specific Call-Outs

  • The 2007 CRF150F uses a mesh oil filter—not a paper cartridge—which should be cleaned and reused, not replaced unless damaged.
  • Oil capacity is just over 1 quart (typically around 1.1 US quarts), but always use the dipstick to verify the final fill level.
  • The oil filler cap/dipstick is located on the right side of the motorcycle, behind the kickstarter.
  • When checking or filling oil, the dipstick should be inserted but not screwed in for an accurate level reading after an oil change.

Step-by-Step Instructions

  1. Warm up the Engine
    Start your bike and let it idle for 3 to 5 minutes. Warming up the oil makes it flow more easily and ensures better drainage.
  2. Park Safely
    Place the motorcycle on its side stand (or a center stand if available) on a firm and level surface.
    For best results during draining and checking, hold the bike upright and level.
  3. Remove the Skid Plate (if equipped)
    Use the 10mm socket. This provides easier access to the drain bolt. (Specific to many CRF150F models, removal simplifies cleanup and access.)
  4. Set Up Your Drain Pan
    Place the pan under the crankcase. Slide a piece of foil or cardboard between the frame and engine to channel oil and prevent spills on the frame.
  5. Remove the Oil Filler Cap/Dipstick
    Unscrew the cap completely and set it aside. This allows oil to drain more freely.
  6. Remove the Drain Bolt
    Use the 24mm socket to remove the drain bolt at the bottom of the engine.
    Specific tip: Be cautious not to drop the drain plug into the pan.
    Let the oil fully drain. Check that the old O-ring on the drain bolt is still in good condition; replace if needed.
  7. Clean the Mesh Filter
    The CRF150F has a mesh screen behind the drain bolt. Remove, inspect, and gently clean it with clean oil or solvent. Reinstall it before replacing the drain bolt.
  8. Reinstall the Drain Bolt
    Refit the drain bolt with its O-ring. Use a torque wrench to tighten to 11 ft-lbs (per Honda spec for this engine).
  9. Add Fresh Oil
    Place a funnel in the filler hole. Pour in about 1 US quart of fresh 10W-30 motorcycle oil (JASO MA or MB). Do not overfill.
    Note: The total spec is just over 1 quart, so start a little under and top off after checking the level.
  10. Check the Oil Level
    Hold the bike upright and level. Insert, but do not screw in, the dipstick, then remove to read the level.
    The oil should be between the upper and lower marks, closer to the upper mark for best results.
    Add oil little by little if necessary, checking each time.
  11. Reinstall the Filler Cap/Dipstick
    Tighten securely.
  12. Start Engine and Check for Leaks
    Start the bike and idle for 2-3 minutes. Shut off and inspect around the drain bolt and filler for leaks.
  13. Final Oil Check
    After the engine cools for a few minutes, check the oil level once more, and top off if needed. Reinstall skid plate if removed.

Additional Tips for 2007 CRF150F Owners

  • If you have stripped the drain plug threads, repair kits are available—never ride with a stripped or leaking drain plug.
  • Always use oil that meets at least JASO MA/MB spec to ensure compatibility with the engine and clutch.
  • Oil changes should be done every 600 to 1,000 miles or after several heavy off-road rides, whichever comes first.
