Changing the oil in your 2022 GAS GAS MC 250 is crucial for maintaining engine health and peak performance. This step-by-step guide, proprietary to MotoSport.com, will walk you through the process, outline all the tools you'll need, and include specific information for this model.

Tools and Equipment Needed

  • 13mm socket or 13mm wrench (for drain bolt)
  • 8mm Allen wrench or T-handle (for oil filter cover bolts)
  • Drain pan (to catch used oil)
  • Clean shop rag (for cleanup and wiping parts)
  • Needle nose pliers (optional, for oil filter removal)
  • New oil filter
  • Replacement engine oil (check your owner's manual for recommended type and amount)
  • Replacement crush washer (recommended for drain bolt to ensure good seal)
  • Torque wrench (for precise reinstallation of bolts)
  • Contact cleaner (for cleaning any oil residue)
  • Correct oil stand or bike lift (see notes below)

Safety and Preparation

  • Ensure your bike is on a stable, flat surface using a proper bike stand. Important call-out: Do not use a traditional flat stand, as it may block access to the drain bolt. Instead, use a stand that allows access or lets you lean the bike for better drainage and convenience (especially crucial for the MC 250F and similar models of this generation)

    .
  • Allow the engine to cool slightly, but changing oil when it's warm helps it drain better.
  • Gather all supplies before starting.

Step-by-Step Instructions

  1. Drain the Old Oil
    • Place your drain pan underneath the engine.
    • Locate the 13mm drain bolt beneath the engine. Use a 13mm socket or wrench to loosen and remove the drain bolt

      .
    • Allow the oil to drain completely. Gently lean the bike to the side to help evacuate as much old oil as possible (this is a helpful tip specific to this frame/engine type)

      .
    • Inspect the magnet on the drain bolt for metallic debris; clean it thoroughly. If the crush washer is damaged or misshapen, replace it

      .
  2. Remove and Replace the Oil Filter
    • Locate the oil filter cover, typically held by 8mm bolts (use an Allen wrench or T-handle)

      .
    • Remove both bolts and carefully pull off the cover.
    • If the oil filter is stuck, gently use needle nose pliers to slide it out.

    • Install the new oil filter, ensuring it is oriented the same way as the one removed. Lightly oil the new filter's rubber seal before fitting.
    • Check the cover O-ring for damage and replace if needed

      .
  3. Clean and Reinstall the Oil Screens
    • If your bike has oil screens (some models do), remove them (often located near the drain area).
    • Clean thoroughly with contact cleaner and inspect for metal shavings

      .
    • Lubricate the O-rings, inspect for wear, and reinstall (be sure the screen is seated properly–misalignment can allow debris past and cause damage to the oil pump gears)

      .
  4. Reinstall the Drain Bolt
    • Thread in the drain bolt with the new or cleaned crush washer.
    • Tighten to recommended torque: for the MC 250 series, 14.8 ft-lbs (20 Nm) is typical, but always check your manual to confirm

      .
  5. Add Fresh Oil
    • Remove the oil fill cap on the engine case.
    • Pour in the recommended specification and quantity of oil (generally about 1.0 liter, but confirm with your owner's manual).
    • Replace and tighten the fill cap.
    • Start the engine and let it idle for 1–2 minutes. Check for leaks at the drain bolt and oil filter cover.
    • Let the engine rest a minute, then check the oil level using the sight glass or dipstick. Adjust oil level if necessary.
  6. Final Checks and Clean-Up
    • Wipe any spilled oil off the engine and frame with a clean rag and contact cleaner

      .
    • Dispose of old oil responsibly at an appropriate recycling facility.
    • Check again for leaks after your first short ride.

Model-Specific Call-Outs for 2022 GAS GAS MC 250

  • This procedure works for both the MC 250F (four-stroke) and the standard MC 250 (two-stroke), but note that the two-stroke models primarily use gear oil, whereas the four-stroke uses engine oil with a filter.
  • Always use the correct bike stand; improper lifting can block access to the oil drain bolt on this frame

    .
  • Replacement intervals: Routine oil changes should occur more frequently under heavy use or racing conditions. Always check your owner's manual for intervals and lubrication recommendations

    .
  • Inspect for excess metal on the magnetic drain plug and oil screens every oil change. Persistent debris may indicate abnormal engine wear

    .
