Performing this maintenance yourself ensures your bike's engine runs smoothly and prolongs its lifespan. Follow these steps for a successful oil and filter change.

Tools and Supplies Needed

  • Engine oil: Pro Honda GN4 4-stroke oil or equivalent (API SJ or higher, JASO T 903 MA, viscosity 10W-30)
  • Oil filter (Honda OEM or trusted aftermarket replacement)
  • Sealing washer (crush washer) for drain bolt
  • Oil filter cover gasket (recommended best practice with filter change)
  • Drain pan
  • Torque wrench
  • Socket set (8mm and 12mm sockets; check your skid plate hardware)
  • 4mm Allen key (if skid plate requires removal)
  • Contact cleaner (optional, for cleaning surfaces)
  • Measuring cup for oil
  • Rags and gloves for cleanup
  • Safety glasses

Preparation Steps

  • Readiness: Make sure the engine is off and the bike is cool enough to handle, but warm enough for the oil to flow freely. Run the engine for just a couple of minutes, then turn it off.
  • Place the bike on the side stand on a level surface.
  • Gather all tools and supplies.

Oil and Oil Filter Change Instructions

  1. Remove the skid plate (if equipped). Use an Allen key or correct socket size. This improves access to the drain bolt and filter.
  2. Remove the oil filler cap (top of the engine, right side). This allows oil to drain faster.
  3. Place your drain pan under the engine's oil drain bolt.
  4. Remove the oil drain bolt and sealing washer using a socket (typically 12mm).
    • Let the oil drain completely – wait until it runs to a drip.
    • Replace the sealing washer with a new one for best sealing performance.
  5. Clean and reinstall the drain bolt:
    • Apply a little fresh engine oil to the threads and seating surface before reinstalling.
    • Install the drain bolt and torque to 24 N·m (18 lb·ft) as specified.
  6. Remove the oil filter cover:
    • Undo the cover bolts (usually 4, 8mm socket).
    • Remove the cover, spring, gasket, and filter.
  7. Remove and replace the oil filter:
    • Install the new oil filter. The side with the rubber seal and hole faces inward (engine side). Installing the filter backwards can cause severe engine damage. If the filter is marked, "OUT-SIDE" faces out.
    • Insert the filter spring into the oil filter cover.
    • Install the filter cover with a new gasket if required. Tighten bolts evenly and securely.
  8. Refill with fresh oil:
    • For a change with filter: add 1.5 liters (1.6 US quarts) of oil.
    • For oil change without filter: 1.4 liters (1.5 US quarts).
    • Pour oil in slowly and check level as you approach the recommended amount.
  9. Check the oil level:
    • Start the engine and let it idle for about 3 minutes. Shut it off, wait 2–3 minutes for oil to settle.
    • With the bike upright (vertical) on level ground, check the oil sight glass on the case – oil should be between the upper and lower marks.
    • Do not overfill.
  10. Check for oil leaks at the drain plug and filter cover.
  11. Reinstall the oil filler cap and skid plate.
  12. Clean up and dispose of old oil according to local regulations.

2022 Honda CRF300L RALLY ABS Specific Call-Outs

  • There is no significant difference for changing the oil between the standard and ABS or Rally models.
  • Engine oil and filter part numbers and drain plug location remain unchanged for Rally and ABS versions.
  • Use the correct oil capacity for filter vs. no filter change.
  • If equipped with aftermarket skid plates or accessories, removal may require different tools or extra steps.
  • Always use a new crush washer for the drain bolt; neglecting this may cause leaks.
  • Be extremely careful to insert the oil filter with the correct side facing in. Serious engine damage will result from incorrect installation.

Oil Recommendations

  • Use Pro Honda GN4 10W-30 4-stroke oil or a high-quality equivalent. Ensure API (SJ or higher; not resource conserving) and JASO T 903 standard: MA.
  • Do not use “energy conserving” or “resource conserving” automotive oils.

Final Checks

  • Visually inspect all mating surfaces for leaks.
  • Note the next service interval: Change oil and filter after the first 600 miles (1,000 km) then every 8,000 miles (12,800 km) or annually, whichever comes first.
  • Record the date, mileage, and type/amount of oil used in your maintenance log.

By following these steps and using the recommended tools and supplies, you’ll keep your 2022 Honda CRF300L RALLY ABS performing optimally for future adventures. Enjoy the ride—and trust MotoSport.com for all your maintenance needs.
