Changing the oil in your 2019 Honda CRF250L Rally is one of the most important maintenance tasks to keep your bike running smoothly and reliably. Below, you'll find a detailed, step-by-step blog dedicated to the process, packed with proprietary MotoSport.com expertise and specific call-outs for your make and model.

Tools and Supplies Needed

  • 8mm and 12mm sockets (deep well preferred)
  • Ratchet
  • Torque wrench (recommended for reinstalling drain bolt)
  • Allen key (if you need to remove a skid plate)
  • Oil drain pan
  • Funnel
  • Paper towels and rags
  • Contact cleaner or degreaser
  • Rubber gloves and safety glasses
  • New oil filter (OEM or Hiflofiltro HF112)
  • New crush washer for the drain bolt
  • New oil filter cover gasket (recommended by Honda; can be reused a few times if in good condition)
  • 1.6 quarts (1.5 liters) of 10W-30 motor oil (Honda recommends SAE 10W-30, JASO T 903 standard MA, or Pro Honda GN4 10W-30)

Preparation

  • Warm up the engine by letting the bike idle for 3-5 minutes. Warm oil drains faster and more completely.
  • Shut off the engine and place the bike on a level surface using either the side stand or a bike stand.
  • If equipped, remove your skid plate using the Allen key or sockets. Some skid plates have drain plug cutouts, but oil may spill onto the plate, so removing it is ideal for a mess-free oil change.

Step-by-Step Oil Change: 2019 Honda CRF250L Rally

  1. Remove the oil filler cap. This allows oil to drain freely and prevents a vacuum from forming. Place the cap somewhere clean and safe .
  2. Clean around the drain bolt area to prevent contamination. Use rags or contact cleaner .
  3. Position the drain pan under the engine’s drain bolt.
  4. Remove the drain bolt with crush washer using the 12mm socket and ratchet. Allow the oil to drain completely. Inspect the crush washer and replace with a new one if possible, as Honda recommends .
  5. Remove the oil filter cover using the appropriate socket. There are usually three 8mm bolts. Carefully remove the cover, noting the position of the gasket and spring .
  6. Remove the oil filter. Pull out the old filter and let excess oil drain into the pan. Inspect the filter for metal particles or debris as a precaution.
  7. Clean the oil filter cover and gasket. If the gasket is in good condition, you may reuse it, but Honda recommends a new gasket each change. Clean any sludge or debris from the cover .
  8. Install the new oil filter. Place the new filter in position (OEM or aftermarket equivalent) and ensure the gasket and spring are seated correctly. Reattach the filter cover and bolts; tighten them evenly.
  9. Reinstall the drain bolt with the new crush washer. Use a torque wrench to tighten to 24 Nm (18 lb-ft) as specified for this model .
  10. Pour in fresh oil. Use a funnel to add 1.6 quarts (1.5 liters) of 10W-30 motorcycle oil. Honda CRF250L Rally’s oil capacity when filter is changed is approximately 1.5 liters; pour slowly and check the level as you go .
  11. Check the oil level. Stand the bike upright and let it settle on level ground. Check the oil through the sight glass or dipstick, ensuring you are within the recommended range (not overfilled). Top up if needed .
  12. Reinstall the oil filler cap securely.
  13. Start the engine and let it idle for a minute. Shut down and check for leaks at the drain plug and oil filter cover. Re-inspect the oil level and top up if necessary.
  14. Reinstall the skid plate if removed.

Model-Specific Call-Outs for the 2019 CRF250L Rally

  • Oil change intervals: Honda recommends changing oil every 4,000 miles (6,400 km), or after the first 600 miles. Regular changes prolong engine life .
