Changing the oil in your 2016 Honda CRF150F is a crucial part of regular maintenance to keep your dirt bike running smoothly and ensure engine longevity. This comprehensive guide—proprietary to MotoSport.com—walks you through every step, listing the essential tools, specific model call-outs, and pro tips to make the job easy, even if this is your first time servicing your CRF150F. Always consult your owner’s manual for official specifications.

Tools & Supplies Needed

  • 10mm, 12mm, and 24mm socket wrenches – Needed for skid plate removal and oil drain bolt.
  • Socket extension and ratchet
  • Oil drain pan
  • Clean rags or shop towels
  • Heat-resistant gloves (optional, but recommended for safety)
  • Aluminum foil – For protecting the frame from spills (optional, but highly useful).
  • New crush washer for drain bolt (advisable to replace every oil change)
  • Engine oil – Honda recommends about 1.1 US quarts (or 1.04 liters) of 10W-30 motorcycle oil that meets JASO MA/MA2 or equivalent.
  • Funnel (for cleaner refilling)

CRF150F Model-Specific Call-Outs

  • No replaceable oil filter – The 2016 CRF150F uses a mesh oil screen that’s cleaned and reused, not replaced. There is no cartridge oil filter on this model—unlike some other Honda off-road bikes.
    Note: Older models (2003–2005) may reference a screen in the crankcase, but for your 2016 model, regular oil changes are your primary method of keeping oil clean.
  • Skid plate removal required – The skid plate is held on with two bolts (10mm and 12mm). It must be removed to access the drain plug.
  • Oil drain bolt size – The drain bolt requires a 24mm socket. Make sure to use care and avoid over-tightening, as the case threads can potentially strip if excessive force is applied.
  • Dipstick check – The dipstick is found behind the kickstarter and must be unscrewed completely for an accurate oil check.

Step-by-Step Oil Change Process

  • Warm up the engine
    Run the motorcycle for a few minutes to warm the oil. Warm oil thins out, making it easier to drain along with contaminants. Turn off the engine and wait a minute before proceeding.
  • Remove the skid plate
    Use a 10mm and a 12mm socket to unscrew the bolts securing the skid plate. Remove it and set aside. This exposes the underside of the engine and the oil drain bolt.
    Tip: This is a good time to clean any caked mud or debris from the area.
  • Protect your frame
    Lay a piece of aluminum foil over the frame to catch any oil drips. This helps prevent oil from making a mess on the lower frame.
    Optional, but makes cleanup much easier.
  • Locate and remove the drain plug
    With your drain pan positioned underneath, use a 24mm socket to loosen and remove the oil drain bolt. Allow all the oil to drain completely. Replace the crush washer if needed.
  • Clean the drain bolt
    Wipe the drain bolt and crush washer clean. Inspect threads for damage. If they’re stripped or you notice significant wear, replace the bolt to prevent leaks.
  • Reinstall the drain bolt
    Tighten the bolt to 11 ft-lbs (15 Nm) of torque. Avoid overtightening which can strip the threads.
  • Remove and inspect the mesh screen (if applicable)
    This model typically doesn’t have an easily-accessible external mesh screen. If you do find a screen in the owner’s manual or parts diagram, remove, clean, and reinstall it as directed.
  • Refill with new oil
    1. Locate the oil filler cap (behind the kickstarter, right side).
    2. Remove the dipstick and insert a funnel.
    3. Pour in 1.1 US quarts (1.04 liters) of 10W-30 motorcycle oil. Pour slowly and check oil level as you near the maximum fill.
    4. Reinsert the dipstick, threading it all the way in—then remove to check the oil level. Add oil if below the fill line.
  • Run and recheck
    Start the engine and let it idle for 2–3 minutes. Shut off and let the oil settle. Recheck the oil level and top off if necessary.
    Caution: Hold the bike level when checking oil for accuracy.
  • Final check and reassembly
    Inspect for leaks at the drain bolt and fill area. Wipe down any excess oil. Reinstall the skid plate, tightening all bolts securely.

Extra Tips for the CRF150F

  • Replace the crush washer every oil change to prevent leaks.
  • Dispose of old oil responsibly—take it to a certified recycling facility.
  • Check your owner’s manual for any model-year-specific changes or torque specs.
  • With the 2016 CRF150F, oil changes are your main engine maintenance. Stay on schedule to extend engine life and maximize reliability.

Troubleshooting & Cautions

  • If the bolt threads are stripped, do not force the bolt. You may need to use an oversized drain bolt repair kit or seek professional help to avoid engine case damage.
  • Only use oil formulated for wet-clutch motorcycles; never substitute with automotive oil.
  • If your oil looks unusually dark or has metallic flake, inspect further for potential engine problems.

Following these steps will ensure your 2016 Honda CRF150F remains in top shape for years of trail riding. Happy riding from MotoSport.com.
