Tools and Supplies Needed

  • 10mm wrench or socket (for the drain bolt)
  • Torque wrench (capable of 18 ft-lbs – 24 Nm)
  • Drain pan
  • Funnel (clean and dedicated to oil use)
  • New engine oil (Honda GN4 4-stroke oil 10W-40 or 20W-50 is recommended; check your climate for viscosity needs)
  • Crush washer (recommended to replace every oil change)
  • Shop towels or rags
  • Gloves (optional, but recommended)

Preparation

  • Let the engine idle for 3–5 minutes; warm oil drains faster and more thoroughly.
  • Turn off the engine and let the bike cool briefly so parts remain safe to touch.
  • Park the bike upright on a stand or level ground for stability.

Step-by-Step Oil Change Instructions

  1. Locate the Drain Bolt
    • The oil drain bolt is found on the bottom-left side of the engine case. Place your drain pan beneath the bolt to catch old oil.
  2. Remove the Drain Bolt
    • Using your 10mm wrench or socket, loosen and remove the drain bolt and its crush washer. Let the oil completely drain into the pan.
  3. Inspect and Replace Crush Washer
    • Check the crush washer for wear or deformation and replace it with a new one every oil change to prevent leaks.
  4. Reinstall the Drain Bolt
    • Hand-thread the bolt and new washer back into the case, then use a torque wrench to tighten to 18 ft-lbs (24 Nm)—do not over-tighten.
  5. Remove the Oil Filler Cap
    • Wipe the area clean around the filler cap before opening–to prevent dirt from entering the engine.
    • Remove the filler cap, usually found on the right-hand side of the engine.
  6. Add New Oil
    • Using a clean funnel, pour in the recommended oil (approx. 0.9 quart / 0.85 liter).
    • Do not use oil additives—Honda recommends only the approved oil for the proper functioning of the wet clutch system.
  7. Let Oil Settle and Check Oil Level
    • Wait a minute for new oil to settle, then insert (but do not screw in) the dipstick or check the sight glass (depending on your specific bike).
    • The oil level should be within the recommended range. Add small amounts as needed until full–not overfilled.
  8. Run and Recheck
    • Start the bike, let it idle for a couple of minutes, then shut it off and wait for one minute.
    • Re-check the oil level and add more if necessary.

Important Model-Specific Call-outs for the 2013 Honda CRF80F

  • The CRF80F does not have a spin-on oil filter; only the oil should be changed.
  • Always use a new crush washer to guarantee a tight seal.
  • Torque the oil drain bolt to 18 ft-lbs (24 Nm)—this is critical to avoid stripping threads or leaks.
  • When checking oil, do not screw in the dipstick; simply insert and remove to read the level.
  • Do not use aftermarket or automotive oil additives; these can potentially damage your bike’s wet clutch system.
  • Be meticulous about cleaning the area around the oil filler to avoid contamination inside the engine.

Disposal and Finishing Touches

  • Dispose of the old oil responsibly at a recycling center or auto parts store.
  • Double-check that the drain plug and filler cap are fully tightened and that there are no leaks before riding.
  • Keep a maintenance log for reference on your next service interval (Honda recommends changing the oil regularly based on use—refer to your manual for specifics).

Keep your 2013 Honda CRF80F in peak condition by changing the oil regularly, and always use recommended supplies and torque specs. For more exclusive resources and OEM-grade parts, trust MotoSport.com—your authority for everything dirt bike.
