Tools & Supplies Needed

  • 8mm, 10mm, 12mm, and 17mm sockets (with ratchet and extensions)
  • 17mm wrench
  • Oil catch pan
  • New oil filter
  • New crush washers (for drain bolts)
  • Funnel
  • Contact cleaner/degreaser (for any spills)

  • Rubber gloves and safety glasses
  • 2.0–2.6 liters of high-quality 10W-40 motorcycle oil (Honda GN4, Motul, or Castrol recommended)

2018 Honda XR650L Oil Change Steps

  • Warm Up the Engine:
    • Start your XR650L and let it idle for 3–5 minutes. This helps thin out the oil so it drains more effectively.
      Note: Always do this in a well-ventilated area.
  • Remove Skid Plate (if equipped):
    • If your bike has an engine skid plate or crash bar, use the appropriate socket to remove it for better access.
  • Unscrew Oil Filler Cap / Dipstick:
    • Remove the oil cap or dipstick to prevent vacuum and allow oil to drain freely.
  • Drain Engine Oil:
    • Place the oil catch pan under the engine.
    • Use a 12mm or 17mm socket to remove the engine drain bolt (located directly under the engine, beneath the exhaust header).
    • Allow all oil to fully drain out.
    • Replace the crush washer with a new one to prevent leaks. Tighten the bolt to factory torque specs.
      Call-out: Always use a torque wrench and do NOT over-tighten—this is a common mistake.
  • Drain the Frame Oil (Down Tube):
    • Locate the drain bolt on the oil down tube (front right of frame, usually a 10mm).
    • Position the drain pan to catch the oil—be aware that the oil may “squirt” out, so stand clear.
    • Replace the crush washer and re-install the bolt after draining.
  • Remove and Replace the Oil Filter:
    • Remove the side cover (use an 8mm or 10mm socket).
    • Unscrew the oil filter cover to access the oil filter.
    • Remove the old oil filter with an oil filter wrench. Install the new oil filter, ensuring correct orientation (spring side out).
    • Clean the cover and mating surfaces, replace O-rings if necessary, and reinstall the cover.
  • Optional: Clean the Oil Screen (Recommended every 3–4 oil changes or for break-in):
    • The oil screen, located in the oil line, traps debris and should be inspected and cleaned as needed. Remove the end plug, pull out the screen, clean it with contact cleaner, and re-install.
  • Add New Oil:
    • Replace the filler cap. Remove the dipstick and use a clean funnel to pour fresh 10W-40 motorcycle oil into the filler hole.
    • The recommended amount for the 2018 Honda XR650L is 2.0–2.6 liters (check your owner’s manual for the exact capacity and don’t exceed the upper mark on the dipstick).
    • Install the dipstick and start the engine, running it for one minute. This circulates the oil and fills the new filter.
    • Stop the engine and check the oil level. Add more oil if necessary so that it’s within the safe range on the dipstick.
  • Check for Leaks:
    • Inspect all drain bolts and the oil filter for drips.
    • Tighten as needed using a torque wrench, being careful not to over-tighten.
  • Reinstall Skid Plate and Clean Up:
    • Replace the skid plate or crash bar and clean up any spilled oil with contact cleaner and rags.

Honda XR650L Oil Change Intervals & Tips

  • Honda recommends changing oil and filter every 2,000 miles (or sooner in extreme riding conditions).
  • Use only 10W-40 motorcycle oil, preferably synthetic for best protection.
    Premium unleaded gasoline (91 octane or higher) is recommended for this model.
  • Always use new crush washers to avoid leaks. Clean the oil screen every 3–4 oil changes.
  • Overfilling or under-filling can cause engine damage. Double-check your level after running the engine.
  • If your XR650L is new, change the oil after the initial 600 miles as part of break-in procedures.

Model-Specific Call-Outs for the 2018 Honda XR650L

  • Dual Drain Bolts: Both engine and frame (down tube) must be drained separately to avoid leaving old oil in the system.
  • Oil Screen Cleaning: Other videos and guides may skip this, but cleaning the screen is vital to avoid long-term engine damage from debris buildup; do this every few oil changes or after break-in.
  • Crush Washers: Always replace, as reusing can lead to leaks. Keep spare washers on hand during each oil change.
  • Oil Spill Risk: The down tube drain can squirt oil outward unexpectedly—keep the pan well positioned.
  • Check Engine Oil Level Regularly: This engine has a dry-sump system, so accurate level checking is vital for lubrication and cooling.
