Regular oil changes are vital for the performance and longevity of your 2017 Honda CRF150R. This robust guide—exclusive to MotoSport.com—covers everything you need, every step, and details specific call-outs for this exact model.

Tools & Supplies Needed

  • 10mm and 12mm sockets or wrenches
  • Oil drain pan
  • Clean funnel
  • Shop rags
  • New oil filter (if replacing)
  • Replacement crush washers for drain bolts
  • Recommended engine oil: Honda GN4 10W-40 (or equivalent motorcycle-specific oil)
  • Measuring cup (for precise CC amounts)
  • Torque wrench (optional but highly recommended)
  • Gloves

Preparation

  • Ensure the bike is upright on a stand and the engine is warm but not hot. Warm oil drains more effectively and removes more contaminants.
  • Clean the area around the drain bolts and fill caps to prevent dirt from entering the engine.

Step-by-Step Oil Change Instructions

  1. Remove the Oil Fill Cap
    Loosen and remove the oil fill cap/dipstick to allow the oil to drain quickly.
  2. Drain Engine Oil (Crankcase)
    • Place the drain pan under the engine’s right side (engine drain bolt).
    • Using the appropriate socket, carefully remove the drain bolt.
    • Allow the oil to fully drain. Inspect the old washer and replace with a new crush washer if needed (recommended every oil change to prevent leaks).
    • Call-out: The 2017 CRF150R requires precision with the drain bolts. The threads are soft—do not overtighten to avoid stripping.
  3. Drain Transmission Oil (if doing both sides)
    • Locate and remove the transmission side drain bolt (left side of the engine). Use a fresh crush washer and avoid overtightening.
    • Let the fluid drain completely, then reinstall the bolt to spec (refer to your owner’s manual for torque specs).
  4. Replace the Oil Filter (Optional but recommended)
    • If changing, remove the oil filter cover bolts, then take out the filter. Clean the seating surface, inspect the o-ring, and install the new filter.
    • Reinstall the cover, tightening evenly. Do not overcompress the o-ring.
  5. Install Drain Bolts
    • Hand-tighten until seated, then use a torque wrench (if available) to manufacturer spec.
    • Replace crush washers. Do not reuse old washers—leaks are common if you do.
  6. Add Oil
    • Using a funnel, add 590cc of 10W-40 motorcycle oil for engine side if changing filter; 560cc if not changing filter

      .
    • For the transmission side, pour in 580cc of oil

      .
    • Do not overfill. Add oil slowly and check level with the dipstick (screw it in to check).
    • CRF150R owners: Because of the split engine/clutch design, the engine and transmission oils are filled separately—don’t mix up the fill points.
  7. Inspect and Start the Engine
    • Install the oil fill caps/dipsticks tightly.
    • Start the engine and let it idle for a few minutes. Check for leaks at both drain bolts and the oil filter cover.
    • Shut off the engine, let it sit for two minutes, then check the oil level again and top off if needed

      .
  8. Dispose of Old Oil Properly
    • Take the used oil and filter to a recycling center or auto parts store.

Important Model-Specific Call-Outs for the 2017 CRF150R

  • Dual Oil System: The CRF150R uses separate engine and transmission oils. Be sure to drain and fill both reservoirs separately.
  • Precise Oil Quantity: 2017 CRF150R owners should use:
    • Engine side: 590cc (with filter) or 560cc (without filter)
    • Transmission side: 580cc
  • Sensitive Drain Bolt Threads: Over-torquing can strip the soft aluminum threads. Use a torque wrench where possible.
  • New Crush Washers: Replace every oil change for leak-free operation

    .
  • Clutch Proximity: Add transmission oil slowly to avoid overflow, as the clutch sits just inside the fill point

    .

Frequently Asked Tips

  • Warm up the engine before draining for faster, more complete oil removal.
  • Always use a clean funnel to avoid introducing debris into the engine.
  • Never re-use old oil filters or crush washers, as they may compromise sealing and protection.
  • Record your mileage or hours run since the last oil change; regular maintenance extends the bike’s life and performance.
