Keeping your 2018 Honda CRF250L Rally ABS in peak running condition depends on regular maintenance, and one of the most important tasks is changing the engine oil. This guide is proprietary to MotoSport.com and will walk you through every step, with model-specific call-outs and best practices for a clean, safe oil change.

Tools & Supplies Needed

  • 8mm and 12mm sockets (deep well preferred)
  • Ratchet wrench
  • Torque wrench (recommended for best results)
  • Allen key (for removing the skid plate, if installed)
  • Oil catch pan
  • Funnel
  • Rubber gloves
  • Safety glasses
  • Rags or paper towels
  • Contact or brake cleaner (for cleaning surfaces)
  • OEM or aftermarket oil filter (e.g., Hiflofiltro HF112)
  • New oil filter cover gasket
  • New crush washer for the drain bolt
  • 1.6 quarts of 10W-30 motorcycle oil (meeting JASO T 903 standard MA or API SG or higher, e.g., Pro Honda GN4 10W-30)
  • Optional: Magnetic drain bolt upgrade

Model-Specific Call-Outs

  • Service Interval:– Honda recommends changing the oil every 8,000 miles (or every 12 months), though some recommend 4,000 miles for frequent/rigorous riding. First oil change should be done at 600 miles.
    Source:– Honda owner's manual, maintenance guides
  • Oil Capacity:– Approximately 1.6 quarts needed for a full oil and filter change.
  • Oil Filter:– Replacement filter example: Hiflofiltro HF112.
  • Drain Plug Bolt Torque:– Tighten to 24 Nm (18 lb-ft) using a torque wrench.
  • ABS System:– The ABS version has no impact on the oil change process — treat as you would the standard Rally or CRF250L.
  • Skid Plate:– If you have an aftermarket or stock skid plate, removal is much easier for access and prevents mess from accidental oil spills.
  • Oil Level Check:– Always check the oil using the sight glass with the bike upright and level, not on the side stand.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start the bike and let it idle for 3-5 minutes to warm the oil for better draining.
  2. Remove Engine Skid Plate (if equipped)
    • Use the Allen key or appropriate tool to remove the skid plate.
    • If your plate has a cut-out, check if it's easier and cleaner to remove completely.
  3. Clean the Area
    • Spray around the drain plug, oil filter cover, and oil fill cap with contact cleaner to prevent contamination.
  4. Remove Fill Cap
    • On the right side, remove the oil fill cap to allow oil to drain faster and more completely.
  5. Drain the Oil
    • Place the oil catch pan beneath the engine drain bolt (bottom of engine).
    • Use a 12mm socket and carefully remove the drain bolt and crush washer, allowing all oil to drain.
    • Inspect and discard the old crush washer – replace with a new one as recommended.
    • Let oil drain fully (at least 5-10 minutes).
  6. Remove and Replace the Oil Filter
    • Use an 8mm socket to loosen the oil filter cover bolts on the right side of the engine.
    • Remove the cover, gently prying it off if necessary. Pay attention to the spring and orientation of the old filter.
    • Remove and discard the old filter and filter cover gasket.
    • Clean the filter cover thoroughly; install the new gasket.
    • Place the new oil filter in the correct orientation; reinstall the spring (if equipped).
    • Reattach the oil filter cover, hand-tighten bolts, then torque to manufacturer specs.
  7. Reinstall Drain Bolt
    • Install the new crush washer, thread in the drain bolt by hand, then torque to 24 Nm (18 lb-ft).
    • Pro Tip: Consider swapping in a magnetic drain bolt to catch future debris.
  8. Add New Oil
    • Insert a clean funnel into the oil fill opening.
    • Pour in 1.6 quarts of 10W-30 motorcycle oil. Do not overfill.
    • Replace and tighten the oil fill cap.
  9. Start the Engine and Check Oil Level
    • Start the motorcycle and let it idle for about 1 minute; check underneath for leaks near the drain bolt and oil filter cover.
    • Shut off the engine and wait a few minutes for oil to settle.
    • With the bike level (not on side stand), check the sight glass. Oil should be between the low and high marks.
    • Add oil if necessary and repeat check.
  10. Finish Up
    • Reinstall the skid plate if you removed it.
    • Wipe away any spilled oil, double-check for leaks after your next short ride.
    • Dispose of your old oil and filter properly at a recycling facility.
    • Reset your maintenance log or reminder as needed.
