Keeping your 2013 Honda CRF250R running smoothly and reliably starts with regular oil changes.

This in-depth guide, proprietary to MotoSport.com, covers everything you need to know for a successful oil change—just like the pros.

Tools and Materials Needed

  • 8mm socket or wrench (for oil filter cover)
  • 12mm socket or wrench (for drain bolts)
  • Torque wrench
  • Drain pan
  • Clean rags
  • New oil filter (OEM recommended)
  • Fresh engine oil (API standard, see manual for viscosity; many use 10W-40 full synthetic)
  • Replacement O-rings/crush washers (recommended for drain and filter areas)
  • Funnel for pouring oil
  • Latex gloves
  • Bike stand (to keep the bike upright and stable)

Key Model-Specific Callouts for the 2013 CRF250R

  • The 2013 CRF250R has separate engine oil and transmission oil compartments, requiring two different oil changes if maintaining both systems.
  • Do not overfill with oil; adding the precise amount and checking the level after warm-up is essential for longevity and performance.
  • Access to the drain bolts can be tight, especially around the shifter on the left (transmission) side.
  • Always warm the engine before draining oil to ensure a full drain and consistent measurement.

Step-by-Step Oil Change Instructions

  1. Warm the Engine
    • Start the bike and let it idle for about 3 minutes.
    • This thins the oil, helping it drain completely and more quickly.
    • Shut the bike off and let it sit for an additional 3 minutes to cool slightly.
  2. Stabilize the Bike
    • Place your CRF250R on a stand to keep it upright and level.
  3. Remove the Skid Plate (if applicable)
    • Use a 10mm socket if your skid plate blocks the drain bolts or oil filter area (stock plates often do).
  4. Drain the Engine Oil
    • Locate the engine oil drain bolt (12mm) on the bottom right side of the engine.
    • Place a drain pan underneath and remove the bolt. Allow oil to drain completely.
    • Inspect the crush washer and replace if damaged.
  5. Drain the Transmission Oil (if desired)
    • Locate the transmission oil drain bolt (12mm) directly beneath the left side, behind the shifter.
    • Remove this bolt and let all transmission oil drain.
    • Inspect and replace the crush washer.
  6. Remove and Replace the Oil Filter
    • Locate the oil filter cover (right side of the engine) with two 8mm bolts.
    • Carefully remove the cover, catching any remaining oil.
    • Take out the old oil filter and the rubber O-ring. Clean the filter housing area.
    • Install a new oil filter in the correct orientation, lightly oil the O-ring, and refit cover using 8mm bolts. Do not overtighten.
  7. Reinstall Drain Bolts & Filter Cover
    • Tighten all bolts to specification using a torque wrench (consult your factory manual for correct values: usually around 12 Nm for drain bolts).
  8. Add Fresh Oil
    • Remove the engine oil fill cap/dipstick on the right. Add oil slowly using a funnel.
    • Tip for CRF250R: Do not just dump in the full recommended capacity. Instead, add oil until it just begins to flow from the level check bolt hole (see your manual for location), which is a more accurate method than measuring volume alone, as the manual cautions that the exact stated cc may sometimes be too much.
    • Reinstall the fill cap/dipstick.
    • Repeat similarly for transmission oil if you drained that side (use the correct compartment and fluid type).
  9. Check the Oil Level
    • Start the bike and run it for a few minutes to circulate the new oil through the system.
    • Shut off the engine and let it sit for a minute. Then, with the bike upright, remove the dipstick, wipe clean, reinsert (do not screw in), then remove and check the oil level. It should be between the upper and lower marks.
    • Add oil as necessary. Avoid overfilling, as this can cause foaming and engine damage.
  10. Inspect for Leaks and Refit Skid Plate
    • Check around all bolts, the oil filter, and the bottom of the engine for any signs of leakage.
    • Reinstall the skid plate.
  11. Dispose of Used Oil Properly
    • Always take used oil to a recycling center or auto parts store offer oil collection.

Pro Tips for a Perfect CRF250R Oil Change

  • Always keep a few spare crush washers and O-rings on hand to ensure leak-free oil changes each time.
  • Inspect drained oil for any metallic shavings (a small amount is normal, excessive amounts can indicate engine wear).
  • Use only the recommended oil type and volumes specified in your owner’s manual.
  • Document each oil change (date, hours, type of oil/filter used) to keep up with your maintenance schedule and for potential resale value.

With these steps, your 2013 Honda CRF250R will stay running strong and ready for whatever you throw at it on the track or trail. For all your parts, filters, or oils—MotoSport.com has you covered.
