Tools and Supplies Needed

  • 10mm or 12mm socket wrench (check your model, typically 12mm)
  • Torque wrench (capable of 18 ft-lbs)
  • Oil drain pan
  • Clean funnel
  • Fresh engine oil (see notes below for type and capacity)
  • Replacement crush washer for the drain plug
  • Rags or shop towels
  • Nitrile gloves (optional, but recommended)

Recommended Oil Type and Capacity

  • Oil Type: Honda GN4 4-stroke or any high-quality 4-stroke motorcycle oil (do not use oil with friction modifiers or oil additives, as it can harm the wet clutch system)
  • Oil Capacity: 0.7 quarts (0.66 liters) for the 2012 CRF80F, always verify in your owner's manual or with your dealer for precise spec for your individual machine.

Preparation

  • Warm up the engine for a few minutes so the oil flows freely, then turn off the ignition.
  • Place the bike on a level surface, using a stand to keep it upright.
  • Allow the engine to cool down slightly to avoid burns.

Step-by-Step Oil Change Instructions

  1. Remove the Skid Plate (If Equipped)
    • If your CRF80F has a skid plate installed, remove it to access the drain plug. Use the appropriate-sized wrench or socket.
  2. Locate and Remove the Oil Drain Plug
    • The drain bolt is underneath the left side of the engine. Place the oil drain pan beneath it.
    • Use a 12mm socket to loosen and remove the drain plug. Allow the oil to drain completely.
    • Replace the crush washer with a new one to ensure a proper seal.
  3. Inspect and Clean Components
    • Clean around the drain plug area before and after removal to prevent contamination of the engine.
    • Wipe off any oil or debris from the drain bolt.
  4. Reinstall the Drain Plug
    • Hand thread the drain plug to avoid cross-threading.
    • Use a torque wrench to tighten the drain plug to 18 ft-lbs (24 Nm) as recommended for the CRF80F, ensuring it is snug but not overtightened.
  5. Add New Oil
    • Remove the oil fill cap, which is typically located on the right side of the engine.
    • Using a clean funnel, slowly pour in 0.7 quarts of fresh 4-stroke motorcycle oil.
    • Do not use a funnel that may be contaminated with other fluids, such as gear oil or coolant.
    • Replace the fill cap securely once finished.
  6. Check Oil Level
    • Let the bike sit for a minute to allow oil to settle.
    • With the bike level, unscrew the dipstick (if equipped), wipe it clean, set it back in without threading, then remove again to check the oil level.
    • The oil should be near the upper level mark but not overfilled.
    • If needed, add oil in small increments and recheck the level.
  7. Run and Recheck
    • Start the engine and let it idle for 3–5 minutes. Check under the bike for leaks.
    • Shut off the engine, wait a few minutes, and recheck the oil level as above, adding oil if necessary.
  8. Dispose of Used Oil Properly
    • Pour the used oil into a sealed container and take it to a recycling center or auto parts store that accepts used motor oil.

Model-Specific CRF80F Tips & Call-Outs

  • Drain Plug Torque: Set your torque wrench to 18 ft-lbs to avoid stripping the threads or causing leaks during reinstallation of the drain plug, as recommended for the CRF80F model.
  • Oil Capacity: Do not overfill—the 2012 CRF80F takes approximately 0.7 quarts (0.66 liters).
  • No Oil Filter: The CRF80F does not use a conventional replaceable oil filter—just drain, refill, and inspect the oil for metal debris or contamination.
  • Oil Additives: Do not use oil additives or “energy conserving” oils, as these can affect the performance and longevity of your wet clutch system.
  • Crush Washer: Always replace the OEM crush washer to prevent leaks. These are inexpensive but vital for a good seal.
  • Proper Oil Check: To accurately check oil level, ensure the bike is upright and on a level surface. Insert the dipstick without threading it in.
  • Spill Management: Clean up all oil drips and residue to avoid attracting dirt to the engine area.

Safety and Environmental Reminders

  • Wear gloves to avoid prolonged contact with used oil.
  • Never dispose of used oil in the trash, on the ground, or down drains—always recycle responsibly.

Conclusion

Routine oil changes are a simple way to keep your Honda CRF80F running at its best. Following this guide ensures you use the correct oil, proper torque settings, and best practices for a clean, fast oil change.
