  • Oil capacity with filter replacement: 1.5 L (1.6 US qt)

Step-by-Step Guide

  • Warm up your engine.

    Start your CRF300L and let it idle for 3-5 minutes. This will help the oil drain more completely by thinning it out.

  • Secure your bike.

    On level ground, use a sturdy stand to hold the motorcycle upright. Remove the key and let the engine cool slightly (but oil should remain warm).

  • Remove the skid plate if equipped.

    Use the appropriate socket to remove the skid plate for easier access to the drain bolt. Place it aside.

  • Place your oil drain pan.

    Put a drain pan under the oil drain bolt at the bottom of the engine.

  • Remove the oil drain bolt.

    Using a 12 mm socket and ratchet, loosen and remove the oil drain bolt. Be careful as oil will begin to flow. Inspect or replace the drain bolt gasket as recommended by Honda.

  • Remove the oil filler cap.

    Unscrew the oil filler cap on the right side of the bike to allow oil to drain more quickly.

  • Allow oil to fully drain.

    Wait several minutes for all old oil to exit the crankcase.

  • Replace the oil filter.

    • Remove the three bolts securing the oil filter cover using the appropriate socket.
    • Take out the old oil filter and the small spring that sits behind it.
    • Clean any debris or sediment from the filter area.
    • Install a new oil filter, placing the spring in the correct orientation behind it.
    • Pre-fill the new oil filter with a bit of fresh oil before installing (optional, but recommended to minimize dry startup).
    • Reinstall the oil filter cover and tighten bolts in a crisscross pattern to 12 N·m (9 lbf·ft).

  • Reinstall the oil drain bolt.

    • Install a new drain bolt gasket if available.
    • Tighten the drain bolt to 24 N·m (18 lbf·ft) with a torque wrench.

  • Refill with fresh oil.

    Using a clean funnel, pour in 1.5 liters (1.6 US qt) of Pro Honda GN4 10W-30 or approved equivalent.

  • Check for leaks.

    Inspect the drain plug and oil filter cover for any leaks as soon as oil is added and again after engine start.

  • Start the engine and let it idle for 30 seconds.

    Shut off the engine and let oil settle for 2-3 minutes.

  • Check the oil level.

    With the bike upright and on level ground, inspect the oil through the sight window. The oil should be near the middle of the window. Add oil in small increments if needed, avoiding overfill.

  • Reinstall the oil filler cap and skid plate.

    Ensure the cap's O-ring is in good condition and lightly lubed with engine oil. Reattach the skid plate if applicable.

  • Dispose of used oil and filter properly.

    Take the old oil and filter to a certified recycling location or your local MotoSport.com dealer.

Additional Tips for the 2024 CRF300L

  • Always double-check torque specs: 24 N·m for the drain bolt, 12 N·m for the oil filter cover bolts.
  • Keep the area around the filler cap clean to prevent debris falling into the engine.
  • If you ride off-road or in dusty conditions, shorten your oil change intervals for best engine protection.
  • Inspect your oil for metallic particles or unusual color as an early warning of possible engine issues.
