Changing the oil on your 2017 Honda CRF250X is an essential part of routine maintenance, ensuring both performance and engine longevity. The process is straightforward but does include a few key steps, specific tools, and important call-outs unique to this model. This proprietary guide from MotoSport.com will walk you through the process with all the details you need.

Required Tools and Materials

  • Sockets (10mm, 12mm, or 13mm sockets as needed)
  • Socket wrench
  • Torque wrench
  • Drain pan
  • Funnel
  • Shop rags
  • Plastic gloves
  • New engine oil (Honda GN4 10W-40 or 10W-30 recommended, per climate)
  • New oil filter (OEM or equivalent)
  • Crush washer for the drain bolt
  • Flat blade screwdriver (if required for removing panels)

Before You Begin

  • Warm up the engine by running it for a few minutes. This helps the oil drain more completely.
  • Find a level workspace and place your bike securely on a stand.

Step-by-Step Oil Change Instructions

  1. Remove the skid plate (if equipped). Use your socket wrench to remove the bolts holding the skid plate in place. Some models have a drain cutout so you may not need to fully remove it. Inspect for rusted or stripped fasteners and address as needed—this is common if the bike has been exposed to the elements.
    Specific note: If bolts are stripped, you may need to weld a nut onto the bolt or use a bolt extractor for removal.
    Call-out: Many CRF250X skid plates have a drain plug access hole. Use it if available, otherwise remove the plate for better access.
  2. Locate the engine oil drain bolt. The drain bolt is typically found underneath the engine. Place your drain pan beneath this area.
    • On the CRF250X, be mindful not to confuse the engine oil drain (underneath engine) with the transmission drain (under the shift lever, left side)
    Call-out: This generation CRF250X features separate engine and transmission oil systems—you’ll drain and refill them separately.
  3. Remove the drain bolt with the appropriate socket. Take care not to burn yourself. Allow the oil to fully drain. Inspect the old oil for discoloration, metal fragments, or strong odors, which could indicate engine wear or other problems.
    Pro tip: Use a clean, clear drain container to inspect the oil as it empties.
  4. Replace the crush washer on the drain bolt. This ensures a proper seal and helps prevent leaks when reinstalling the bolt.
  5. Reinstall and torque the drain bolt to manufacturer specs. Do not overtighten to avoid stripping the crankcase threads.
  6. Remove the oil filler cap (right side of the engine), and the oil filter cover. Use the socket wrench or screwdriver (if required) to remove the three bolts holding the cover. Call-out: The 2017 CRF250X uses a cartridge-style oil filter. Make sure to install it with the correct orientation; there is a spring behind the filter for tension.
  7. Remove the old oil filter. Wipe out the filter cavity with a clean rag. Check that the old filter O-ring does not stick to the engine—replace with the new filter’s supplied O-ring/gasket.
  8. Install the new oil filter. Insert it into the cavity, replace the cover, and torque the bolts evenly.
  9. Add new engine oil:
    • Use a funnel to add oil through the filler hole.
    • Capacity for 2017 CRF250X: Approximately 0.77 quarts (0.73 liters) for an oil and filter change, but check your owner's manual for the precise specification.
    • Use Honda GN4 10W-40 or 10W-30 (per climate). Ensure not to overfill; use the sight glass or dipstick to verify.
    Call-out: Always use oil formulated for wet clutches. Automotive oils may cause clutch slippage.
  10. Reinstall the fill cap and run the engine for 2-3 minutes to circulate the oil. Stop the engine, wait 2-3 minutes, then check the oil level again. Top up as needed.
  11. Inspect for leaks around the drain plug and filter cover. Wipe clean if necessary.
  12. Reinstall the skid plate if removed. Ensure all bolts are securely fastened.

CRF250X-Specific Tips and Call-Outs

  • Separate Transmission Oil: The 2017 CRF250X features separate engine and transmission oil systems. Your transmission oil must be changed independently. The transmission drain plug is located on the left side, underneath the shift lever, and the fill is on the right.
    Use Honda HP Transmission Oil or equivalent. Do not use the same oil type as in the engine unless specified by Honda.
  • Check/Replace Both Drain Washers: If changing both engine and transmission oil, change both washers to avoid leaks.
  • Always Verify Fluid Levels: Double-check levels using the sight glass (if equipped) or dipstick on level ground after the engine has run and cooled for a minute.

Disposal and Environmental Reminder

  • Dispose of all used oil and filters properly—never pour oil down drains or onto the ground. Take it to an authorized recycling or hazardous waste center.

Summary

  • Warm up the engine.
  • Remove skid plate (if necessary).
  • Drain engine oil–don’t confuse with transmission oil.
  • Replace crush washer and reinstall drain plug.
  • Replace oil filter and gasket.
  • Add recommended engine oil, check level, and run engine to circulate.
  • Inspect, top up, and check for leaks.

By following these steps, your 2017 Honda CRF250X will stay in top condition and provide reliable performance on every ride. For OEM parts and high-quality oils, trust MotoSport.com to keep your ride running strong.
