If you own a 2020 Honda CRF250L ABS, performing regular oil changes is crucial for maintaining engine reliability and extending the lifespan of your dirt bike. This detailed, MotoSport.com proprietary guide walks you through changing the oil safely and efficiently, highlighting specific details for this make and model.

Tools and Supplies Needed

  • 8mm and 12mm sockets (deep well preferred)
  • Ratchet wrench (with extension, optional)
  • Torque wrench (recommended for correct bolt tightness)
  • Allen key (to remove skid plate if needed)
  • Oil catch pan
  • Paper towels or rags
  • Replacement oil filter (Hiflofiltro HF112 or K&N 112 recommended)
  • New crush washer for the drain bolt (Honda recommends always replacing)
  • New oil filter gasket (Honda recommends replacing, though it may be reused a few times)
  • 1.6 quarts (1.5 liters) of SAE 10W-30 motorcycle oil (JASO MA rated, such as Pro Honda GN4 10W-30)

Model-Specific Notes

  • First oil change should be done at 600 miles to protect your engine during the break-in period. Afterward, Honda recommends changing the oil every 4,000 miles or 12 months, whichever comes first, to maintain optimal performance and longevity.
    The 2020 CRF250L ABS shares maintenance intervals and procedures with non-ABS models.
  • Skid Plate: The stock skid plate has a cut-out for the drain bolt. If you run an aftermarket skid plate, consider removing it, as oil may collect on its wings or prevent direct access to the drain bolt.
  • ABS Consideration: No special oil change procedure is required for the ABS variant, but avoid pulling on sensor wiring while working near the front of the bike.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start your CRF250L ABS and let it idle for 3–5 minutes. This helps the oil flow out more easily when you drain it. If the engine is cold, this step is important.
  2. Prepare Your Work Area
    • Place the bike on a stable, level surface using the kickstand or a service stand.
    • Lay paper towels or rags around to catch spills.
  3. Remove the Skid Plate (If Required)
    • Use your Allen key to remove the skid plate bolts if your model or aftermarket accessory requires it. For OEM plates, you may be able to leave it in place because of the drain hole.
  4. Drain the Old Oil
    • Position your oil catch pan under the drain bolt, located at the bottom of the engine.
    • With the 12mm socket and ratchet, loosen and remove the drain bolt carefully (watch for hot oil).
    • Remove the oil filler cap on top of the engine to allow oil to flow out faster.
    • Let all oil drain completely—this takes a few minutes.
  5. Replace the Oil Filter
    • Locate the oil filter cover (left side of the engine).
    • Remove the bolts (usually 8mm socket), pull off the cover, and remove the filter.
    • If the oil filter gasket is old, replace it. Lightly oil the new gasket before installation to prevent pinching.
    • Install the new oil filter in the proper orientation (check owner’s manual or the direction on the filter itself).
    • Reinstall the oil filter cover and tighten the bolts evenly to avoid leaks.
  6. Install New Drain Bolt Washer & Reinstall Bolt
    • Replace the crush washer on the drain bolt for a proper seal.
    • Reinstall the drain bolt and hand tighten, then use a torque wrench to tighten to 24 Nm (18 lb-ft) as per Honda’s specification.
  7. Add New Oil
    • Pour in 1.6 quarts of 10W-30 motorcycle oil. (Do not overfill.)
    • Start with less oil, then check with the bike upright and the dipstick re-inserted (not screwed in) to top off to the correct level.
    • Replace the oil filler cap.
  8. Check for Leaks and Final Oil Level
    • Start the engine and idle for a few minutes, then check around the oil drain bolt and filter cover for leaks.
    • Shut off the bike, allow it to rest for a minute, then check the oil level again and top up if needed.
  9. Recycle Used Oil and Parts
    • Dispose of used oil and the old oil filter properly, at an authorized recycling facility or your local automotive store.
  10. Log Your Service
    • Record the date and mileage of your oil change for reference at your next service interval. Regular oil changes prevent engine wear and costly repairs.

Additional Tips

  • If you reuse the crush washer or gasket, inspect them thoroughly for damage; leaks can cause serious engine issues.
  • Always use genuine or high-quality oil and filters to avoid engine warranty issues, especially on newer bikes.
  • While you’re performing an oil change, quickly inspect your coolant level and look for any signs of leaks or loose fasteners.
  • Dispose of all fluids responsibly and keep oil away from tires and brake components for safety.

Why Change Your CRF250L ABS Oil on Schedule?

  • Fresh oil ensures optimal lubrication and cooling of vital engine parts.
  • Neglecting oil changes allows contaminants and wear particles to degrade the engine's performance and reliability.
  • Honda sets the service interval at every 4,000 miles or 12 months; adhering to this schedule is fundamental for dirt-riding longevity and peace of mind.

For Honda CRF250L ABS owners, following this guide helps maintain the bike’s performance and protects your motorcycle investment. Always consult your owner's manual for detailed specifications and double-check all torque values before riding.
