Changing the oil in your 2024 Honda CRF300L RALLY ABS is a crucial maintenance task that keeps your engine performing at its best. This guide is specifically tailored to the ABS Rally model, highlighting key specs and reminders so your MotoSport.com experience is smooth and successful. The steps below ensure you complete this essential job correctly and confidently.

Tools and Supplies Needed

  • Torque wrench (capable of reading 24 N·m or 18 lbf·ft)
  • 8mm and 12mm sockets
  • 4mm Allen wrench (for some skid plate configurations)
  • Oil drain pan
  • Rags or shop towels
  • Rubber gloves (optional, for cleanliness)
  • Safety glasses
  • Contact cleaner (optional, for cleaning spills)
  • Replacement oil filter
  • Replacement drain bolt sealing washer
  • Replacement oil filter cover gasket (recommended)
  • Measuring cup or funnel
  • Recommended oil: Honda GN4 10W-30 or equivalent (API SJ/JASO MA), 1.43 US qt (1.35 L) after draining, 1.5 US qt (1.4 L) after oil and filter change

Step-by-Step Procedure

  1. Warm Up the Engine
    • Start your CRF300L Rally ABS and let it idle for a few minutes until it reaches operating temperature. This helps the old oil flow out easily and removes contaminants

      .
  2. Shut Off the Bike and Prepare
    • Turn off the engine and ensure the bike is stable, using a center stand or paddock stand if available. Place a drain pan beneath the oil drain bolt under the engine

      .
    • Remove the oil filler cap to allow the system to vent and drain smoothly.
  3. Drain the Old Oil
    • Remove the oil drain bolt and its sealing washer (using a 12mm socket). Be cautious—oil may be hot.
    • Allow all the oil to drain completely. Inspect the drain bolt and replace the sealing washer with a new one.
    • Clean the drain bolt, apply a light film of oil to its threads, and reinstall. Torque to 24 N·m (18 lbf·ft)

      .
  4. Replace the Oil Filter
    • Remove the oil filter cover bolts with the 8mm socket (expect four bolts). Carefully take off the oil filter cover with its spring and gasket.
    • Take out the old oil filter. Note the orientation: the rubber seal and hole face inward toward the engine. If your filter has an “OUT-SIDE” mark, it faces out. Improper installation can result in severe engine damage

      .
    • Install the spring into the oil filter cover and fit a new gasket.
    • Insert the new oil filter in the correct direction, reinstall the filter cover, and torque the bolts evenly and securely.
  5. Add New Oil
    • Double-check that both the drain bolt and the oil filter cover are tight before adding new oil.
    • Use a funnel or measuring cup and fill with the specified amount of 10W-30 motorcycle oil.
    • Capacity guidelines:
      • 1.43 US qt (1.35 L) if not replacing the filter (just draining oil)
      • 1.5 US qt (1.4 L) if replacing both oil and filter

  6. Check the Oil Level
    • Put the bike on a level surface. Start the engine, letting it idle for about three minutes, and then turn it off. Wait another two to three minutes

      .
    • Hold the bike upright (not on the side stand) and check the oil level using the sight glass on the engine. The oil should be between the upper and lower marks

      .
    • If oil is low, top up to the upper level mark. Do not overfill.
  7. Final Checks
    • Inspect for leaks around the drain bolt and oil filter cover.
    • Reinstall any removed skid plates and clean up any spilled oil or residue with contact cleaner.
    • Safely dispose of old oil and the used filter at a recycling collection point.

Model-Specific Guidance and Callouts for 2024 CRF300L RALLY ABS

  • The 2024 CRF300L Rally ABS shares most of its oil change procedure with the standard 300L and Rally variants, but always double-check specifics for the ABS model in your owner’s manual.
  • Skid plate design may require extra steps (and tools) for removal, depending on aftermarket accessories.
  • Oil level check requires holding the bike upright and on level ground—do not check with the bike on the side stand.
  • Use only motorcycle-specific oil that meets Honda’s requirements for viscosity and API/JASO ratings (avoid automotive “energy conserving” oils).
  • The “OUT-SIDE” mark on the oil filter (if present) must face out. For genuine Honda filters without the mark, ensure the rubber seal and central hole face into the engine.

  • Engine oil change interval (after break-in): Change the oil and replace the filter initially at 600 miles, then every 8,000 miles or as specified.

Changing the oil on the 2024 Honda CRF300L RALLY ABS is a straightforward, rewarding project that prolongs engine life and keeps your bike riding strong.
