Shop parts for a 2023 Honda CRF150R Dirt Bike.

Changing the engine oil is a critical maintenance task to keep your 2023 Honda CRF150R running smoothly and to extend the life of your dirt bike. Below, you’ll find a robust step-by-step guide including the specific tools required, unique tips for the 2023 CRF150R, and callouts all owners should keep in mind.

Tools and Supplies Needed

  • 10mm socket and ratchet
  • 8mm socket
  • Torque wrench
  • Flathead screwdriver (for prying off washers or O-rings if needed)
  • Oil catch pan
  • Funnel
  • Rags or shop towels
  • New crush washer for drain plug (recommended)
  • New oil filter (if changing)
  • Honda GN4 10W-40 oil or equivalent (see service manual for recommended oil type and capacity)
  • Measuring cup or graduated cylinder for accurate oil measurement
  • Nitrile gloves (optional, for cleanliness)

Preparation

  • Start your bike and let it idle for 3-5 minutes. This warms up the oil, helping it drain more thoroughly and carry contaminants out with it.
  • Shut off the engine and place the CRF150R on a level surface with a stand for stability.
  • Make sure you have your tools and new oil/accessories ready before starting the process.

Step-by-Step Oil Change Instructions

  1. Remove the Oil Filler Cap/Dipstick
    • Unscrew and remove the dipstick from the right side of the engine. This allows oil to drain out cleanly by preventing a vacuum.
  2. Locate and Remove the Engine Oil Drain Bolt
    • With an oil catch pan underneath the engine, use a 10mm socket to remove the drain bolt found at the lowest point of the engine case.
    • Be careful as the oil may be hot.
    • Remove the old crush washer from the bolt if present; replace it with a new one to prevent leaks upon reinstallation.
  3. Drain the Oil Completely
    • Allow all oil to fully drain. Wait a few minutes to ensure maximum removal.
    • Optional: Tip the bike gently (with caution) from side to side to get every last drop out.
  4. Replace the Oil Filter (If Applicable)
    • If you are replacing the oil filter as well, locate the oil filter cover (secured by bolts on the engine case).
    • Remove the cover and take out the old filter. Clean the mating surfaces and install the new filter in the correct orientation.
    • Reinstall and tighten the filter cover bolts to the specified torque.
  5. Reinstall the Drain Bolt
    • Clean the drain bolt threads and replace the washer if needed.
    • Thread the bolt by hand first, then torque to Honda’s specified value for the CRF150R (typically around 12 Nm, but confirm with the owner’s manual).
  6. Add New Engine Oil
    • With a funnel, pour in fresh oil to the correct level.
    • 2023 Honda CRF150R Oil Capacity:
      • With filter change: 590 ml (about 20 oz)
      • Without filter change: 560 ml (about 19 oz)
    • Pour slowly to avoid spills. Use the dipstick to check the level, but allow a few minutes for the oil to settle before checking.
  7. Replace the Oil Filler Cap/Dipstick
    • Reinstall the cap. Ensure it is secure, but don’t over-tighten.
  8. Start the Engine and Check Oil Level
    • Start the bike and let it run for 2-3 minutes. Shut it off and let it sit for a minute or two.
    • Check for leaks around the drain bolt and oil filter cover.
    • Check the oil level with the dipstick. Top off as needed.
  9. Dispose of Used Oil & Filter Properly
    • Take used oil and filters to an authorized recycling center.

CRF150R-Specific Tips and Owner Callouts

  • Be extremely careful not to over-tighten the drain bolt or filter cover bolts. The aluminum engine cases can be damaged easily if overtightened, possibly leading to costly repairs (“don’t strip those drain bolts.”).
  • New washers are recommended for the drain bolt and oil filter cover with every change, as old washers can cause leaks and improper sealing.
  • Always use the Honda-specified oil weight and quality. Honda recommends GN4 10W-40 oil (or equivalent) for best performance.
  • Adding slightly too much oil can impede the clutch performance. Pour in the measured amount, let settle, then confirm with the dipstick.
  • If you’re only changing the oil (not the filter), use the slightly lower oil quantity (560 ml).
  • On the CRF150R, the transmission has a separate oil fill and drain process—do not confuse engine and transmission oils as they are separate circuits.
  • Dispose of oil in compliance with local regulations; never dump it in drains or on the ground.
  • Owner's manual: Reference your Honda CRF150R owner’s manual for detailed diagrams and torque specs for all bolts.
