A regular oil change is essential in maintaining the performance and longevity of your 2024 GAS GAS EX 250 dirt bike. This step-by-step guide, proprietary to MotoSport.com, gives you all the details, special call-outs for this year and model, and the tools required for a robust and safe oil change.

Tools and Supplies Needed

  • 13mm socket or 13mm wrench
  • T30 Torx bit (for some screws)
  • 8mm Allen wrench or T-wrench (for oil filter cover bolts)
  • Oil drain pan
  • Contact cleaner
  • Clean rags
  • Oil filter (check your owner's manual for the correct part number)
  • Fresh engine oil (see owner's manual for type and quantity)
  • Paper funnel (recommended)
  • Crush washer (new, for drain bolt – recommended)
  • Rubber or latex gloves (optional, for cleanliness and safety)

Special Call-Outs for the 2024 GAS GAS EX 250

  • The oil drain bolt is only accessible using a stand with an open base. Do not use a conventional lift stand that blocks access to the bottom of the frame, as you will not be able to access the drain bolt easily

    .
  • Always check and wipe the magnetic tip on the drain bolt for any metallic debris. This is normal in small amounts, but excessive shavings could indicate internal wear

    .
  • The oil filter cover uses two 8mm bolts– do not overtighten them when reinstalling since the housing is lightweight and prone to wear.
  • Check your owner's manual for the required oil quantity. Overfilling or underfilling may affect engine performance

    .
  • Inspect the copper crush washer on the drain bolt and replace it each oil change to ensure a proper seal and prevent leaks.

Step-by-Step Oil Change Procedure

  1. Warm Up the Engine
    • Start the bike and let it idle for a few minutes. This helps the oil thin out and drain more thoroughly.
    • Turn off the engine and allow it to cool for about a minute–never work on a hot engine.
  2. Position the Bike and Gather Supplies
    • Place your EX 250 on a proper stand with bottom access to the drain bolt.
    • Ensure the bike is stable and upright to facilitate complete draining

      .
    • Arrange all required tools and your drain pan within easy reach.
  3. Remove the Drain Bolt and Drain Oil
    • Slide the oil drain pan under the drain bolt (bottom of the engine).
    • Use a 13mm wrench to loosen and remove the drain bolt.
    • Allow old oil to fully drain into the pan. This might take a few minutes.
    • Inspect and clean the magnetic tip of the drain bolt. Replace the copper crush washer if necessary

      .
  4. Remove the Oil Filter
    • Locate the oil filter cover on the right side of the engine.
    • Use an 8mm Allen wrench to remove the two bolts securing the filter cover.
    • Pull the cover off and remove the oil filter. Use pliers if it's stuck, but avoid damaging the housing

      .
    • Compare the old and new oil filters to ensure they match.
  5. Install the New Oil Filter
    • Insert the new oil filter in the correct direction (see filter or bike markings).
    • Reinstall the oil filter cover and secure it with the 8mm bolts. Hand-tighten and finish with a wrench to snug–don't over torque.
  6. Reinstall the Drain Bolt
    • Ensure the bolt and washer are clean and the seating surface is free of old oil or debris.
    • Thread the drain bolt by hand to prevent cross-threading, then tighten with a wrench. Do not overtighten.
  7. Add New Engine Oil
    • Place a funnel in the oil fill opening.
    • Pour in the manufacturer-recommended amount and type of engine oil (refer to the owner's manual for quantity).
    • Wipe away any spills and reinstall the oil fill cap securely.
  8. Check for Leaks and Final Inspection
    • Start the engine and let it idle for about 60 seconds.
    • Turn off the engine and check for oil leaks around the drain bolt and oil filter cover.
    • Inspect oil level (add more if needed).
  9. Dispose of Old Oil Properly
    • Pour used oil into a sealed container and take it to a recycling facility or auto parts store that accepts used oil.
    • Never dispose of oil in regular trash or drains.

Additional Maintenance Tips for the 2024 GAS GAS EX 250

  • Recommended oil change interval: at least every 15 hours of riding. Change more frequently in racing or extreme conditions

    .
  • Visually inspect for oil leaks during routine maintenance.
  • Keep a spare oil filter and crush washer in your garage for quick, clean oil changes.
  • Consult the 2023 GAS GAS EX 250F owner's manual for torque specs and further maintenance information
