Tools and Materials Needed

  • 13mm socket or ratchet with a 13mm wrench (for the drain bolt)

  • 8mm Allen or T-wrench (for oil filter cover bolts, depending on your bike's hardware)

  • 1 liter of Motorex Cross Power 4T 10W/50 full synthetic oil (recommended by GAS GAS)

  • Pliers (for stubborn oil filter removal)
  • Peg-style lift stand or side stand (crucial for proper access on this model)

Special Call-Outs for the 2022 GAS GAS EX 250F

  • Use a peg-style lift stand – The drain bolt is difficult to access with a traditional flat stand. A peg-style stand allows easy access to the drain bolt and helps you tip the bike slightly to ensure complete draining .
  • This procedure is similar to KTM and Husqvarna 250cc 4-stroke models of the same year, but always refer to your user manual for confirmation .
  • The oil change kit fits models from 2021 to 2024 and should include oil, an oil filter, and a crush washer .
  • Drain interval: Change engine oil every 10-15 hours or sooner if riding in hard conditions .

Step-by-Step Oil Change Instructions

  1. Warm Up the Bike
    Start your EX 250F and let it idle for three to five minutes. Warm oil flows better and carries away more particles. Shut off the engine and let it cool just enough so you don't risk burns.
  2. Set Up the Bike
    Place your bike on a peg-style lift stand to allow access to the drain bolt and to tip the bike later for full drainage .
  3. Remove the Skid Plate (If Equipped)
    Some EX 250Fs have a skid plate that may block access to the drain bolt. Remove it using the appropriate tool.
  4. Clean the Area
    Use contact cleaner and a rag to wipe around the drain bolt and oil filter cover. This prevents debris from falling into the engine.
  5. Drain the Old Oil
    • Place your drain pan under the engine.
    • Using a 13mm socket or wrench, carefully loosen and remove the oil drain bolt (located under the engine).
    • Let the oil completely drain into the pan. Gently tilt the bike towards the drain side to get every last drop .
    • Inspect and clean the magnet on the tip of the drain bolt; remove any captured metal shavings .
  6. Replace the Crush Washer
    Remove the old crush washer from the drain bolt and replace it with a new one from your kit .
  7. Reinstall the Drain Bolt
    Tighten the drain bolt with its new crush washer. Be careful not to overtighten. Check your manual for the correct torque spec.
  8. Change the Oil Filter
    • Locate the oil filter cover on the right side of the engine.
    • Remove the two cover bolts using your 8mm Allen or T30 Torx (check what your bike uses).
    • Set bolts aside. Carefully remove the cover—oil will drip from here so keep your pan underneath.
    • Pull out the oil filter. If stubborn, use pliers .
    • Clean the filter housing and cover surfaces with a rag and contact cleaner.
    • Install your new OEM oil filter, ensuring it is oriented correctly (open and closed ends matter—refer to your manual).
    • Replace and tighten the filter cover bolts securely.
  9. Add Fresh Oil
    • Remove the oil fill cap (typically on top of the engine).
    • Pour in 1 liter of Motorex Cross Power 4T 10W/50 synthetic oil .
    • Replace the fill cap.
  10. Check for Leaks and Oil Level
    • Start your engine and idle gently for one minute. Shut off and inspect areas around the plug and filter for leaks.
    • Allow a minute for the oil to settle, then check the oil sight glass or dipstick. Add a splash more if necessary, but don't overfill.
  11. Reinstall Skid Plate (if removed)
  12. Dispose of Used Oil Responsibly
    Take the old oil and filter to a recycling facility.

Additional Expert Tips

  • Always use a new crush washer to prevent leaks .
  • Inspect oil for metallic debris: Small flecks are normal, but large shavings may mean a deeper issue .
  • Write down your hours or mileage after every oil change for accurate future maintenance.
  • Check torque specs in your owner's manual for both the drain bolt and filter cover bolts. This avoids damage to threads and leaking.
