Tools & Supplies Needed

  • 10mm and 12mm sockets or wrenches
  • Socket wrench/ratchet
  • Torque wrench (with ft-lb/Nm scale)
  • Oil drain pan
  • Clean rags or paper towels
  • Funnel
  • Honda recommended engine oil (e.g., 10W-30 or 10W-40, meeting JASO MA/M2)
  • New oil filter
  • New oil drain bolt washer/gasket (recommended)
  • Gloves
  • Skid plate removal tools (if equipped and obstructing the drain bolt)

Preparation

  • Warm up the engine for several minutes so oil drains easily. Let it idle, then turn off the engine.
  • Put the bike on a flat surface using its side stand–the CRF300L RALLY doesn't have a center stand.
  • Remove the skid plate if it blocks access to the oil drain bolt.

Step-by-Step Oil Change Process

  1. Loosen and remove the oil filler cap.
    – Located on the right side of the engine. This step allows the oil to drain smoothly by preventing a vacuum.
  2. Position the drain pan under the engine’s oil drain bolt
    – The drain bolt is under the engine (bottom left side).
  3. Remove the oil drain bolt with a 12mm socket or wrench.
    – Be careful, the oil may be hot. Allow oil to drain completely.
  4. Remove the oil filter cover (using bolts on the right side, next to the sight glass).
    – Take out the old oil filter. Pay attention to the filter’s orientation for proper installation of the new filter.
  5. Inspect and clean the oil filter area and oil filter cover gasket.
    – Remove any old oil or debris. If the gasket is worn or damaged, replace it; Honda recommends always using a new gasket.
  6. Install the new oil filter.
    • If possible, pour a small amount of oil into the filter prior to installation to help reduce startup wear.
    • Lightly oil the rubber seal of the new filter for a proper seal.
    • Install the filter in the correct orientation (per manual/spec).
  7. Reinstall and torque the oil filter cover bolts.
    – Do not over-tighten; refer to your service manual for specs (typically around 9 Nm/6.6 ft-lb).
  8. Install a new sealing washer on the oil drain bolt, then torque it properly.
    – Reinstall the drain bolt and tighten to 18 ft-lb. Avoid over-tightening to prevent thread damage on the crankcase.
  9. Pour in new engine oil through the filler cap opening.
    • If changing oil and filter: Add 1.6 quarts (1.5 liters), then check and top off as needed.
    • If only changing oil (no filter): Add 1.45 quarts (1.35 liters).
  10. Reinstall the oil filler cap.
  11. Run the engine for 1-2 minutes.
    – This helps the oil circulate and fills the filter. Rev lightly and check for leaks.
  12. Turn off engine; wait a few minutes.
    – Allow oil to settle; then, with the bike upright (not leaning), check the oil level through the sight glass beside the filter cover. Top off oil as needed to keep it between the upper and lower marks.
  13. Reinstall skid plate if removed, and clean up.
    – Dispose of old oil and filter properly at a recycling center.

CRF300L RALLY Model-Specific Call-Outs

  • Oil capacity is 1.6 qt (or 1.5L) with filter change for the 2023 Rally model. Double-check using the sight glass after running and settling the engine.
  • Skid plate removal is often necessary for Rally models. Use care not to overtighten skid plate bolts upon reinstallation.
  • Drain bolt torque: 18 ft-lb (24.5 Nm); do not overtighten as the case threads can strip easily.
  • Filter orientation: The open end of the filter faces outward, toward the oil filter cover.
  • Keep the work area clean and protect the engine internals from dust/debris when the filter cover is open.

Additional Tips

  • Change oil after break-in period (first 600 miles), then at recommended intervals per your owner's manual.
  • Use only oils meeting Honda and JASO MA/M2 specs to maintain clutch performance.
  • Check O-rings and sealing washers for each oil/filter change. Always replace if worn or damaged.

Performing regular oil changes yourself on your 2023 Honda CRF300L RALLY is straightforward and rewarding, saving you both money and downtime—keeping you ready for every ride. For genuine parts, tools, and oil, trust MotoSport.com.
