This guide—brought to you by MotoSport.com—walks you through the process, highlights the tools you’ll need, and calls out what makes this process specific to the 2024 GAS GAS MC 50.

Tools and Materials Needed

Key Oil Specifications for 2024 GAS GAS MC 50

  • Type: ATF Dexron 3 transmission oil
  • Capacity: 200ml (approx.)

Step-By-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your MC 50 and let it idle for 2-3 minutes. This warms the oil, making it drain faster and more thoroughly.
  2. Secure the Motorcycle
    • Put the bike on a stand so it’s completely upright and stable.
  3. Remove the Oil Filler Cap
    • Locate the oil filler cap (usually marked, often on the right side of the case) and remove it. Set aside somewhere clean.
  4. Position the Oil Drain Pan
    • Slide your oil catch pan under the bike, beneath the gear case drain bolt.
  5. Remove the Sump/Drain Bolt
    • Using the correct socket, loosen then remove the sump bolt. Call-out: Many 50cc engines use a magnetic drain bolt to capture metal debris; inspect and wipe the magnet clean before reinstallation.
    • Let all oil drain completely into the pan–ideally for 10-15 minutes for a full flush.
  6. Inspect and Clean the Bolt
    • Carefully wipe the sump bolt clean. If magnetic, remove any metal filings.
  7. Reinstall the Drain Bolt
    • Thread the bolt back in by hand to avoid cross-threading. Tighten securely with the wrench–do not overtighten to avoid stripping aluminum threads.
    • For extra leak protection, you may lightly grease the washer if present, as some mechanics recommend.
  8. Add New Oil
    • With a funnel and measuring cup, pour exactly 200ml of ATF Dexron 3 into the oil filler hole. Do not overfill.
    • The MC 50’s oil capacity is critical–overfilling can cause clutch slippage, underfilling risks poor lubrication.
    • A syringe or graduated cup from the hardware store/paint section works perfectly for measurement.
  9. Replace the Oil Filler Cap
    • Ensure the cap and sealing surface are both clean. Reinstall tightly by hand; do not overtighten.
  10. Check for Leaks
    • Wipe down the case and run the bike for 1-2 minutes. Check around the drain bolt and filler cap for any oil seepage.

Special Tips and Important Notes for the 2024 GAS GAS MC 50

  • Oil Type: The MC 50 uses automatic transmission fluid (ATF) Dexron 3 rather than traditional engine oil. Do not substitute with generic engine oil.
  • Oil Volume: Accurately measure 200ml–not more, not less. Overfilling increases pressure on seals, underfilling risks engine damage.
  • Drain Bolt Caution: The engine case on the MC 50 is soft aluminum; never overtighten the drain bolt. Use a torque wrench if possible and refer to the owner's manual for torque specs.
  • Inspect Magnetic Bolt: Check for excess metal debris on the magnetic sump bolt. A normal trace is okay, but chunks or heavy filings can indicate internal wear.
  • Change Frequency: For long clutch life and best performance, change the gear/clutch oil every 5-10 hours of racing or strenuous trail riding.
  • Consult the Manual: Always refer to the 2024 GAS GAS MC 50 owner’s manual for updates or model-year specific notes, as specs or procedures may vary. Torque settings and diagrams are typically included there.
