Regular oil changes are vital for your 2022 GAS GAS EC 250, ensuring smooth performance and extending engine life. This proprietary MotoSport.com guide details everything you need, including specific model tips for an efficient oil change.

Tools and Supplies Needed

  • Oil filter (new)
  • Engine oil (type and quantity per manual)
  • 8mm T-handle wrench
  • 8mm Allen wrench
  • 13mm ratchet
  • Drain pan
  • Clean rags
  • Needle nose pliers (for oil filter removal, as needed)
  • Crush washer (fresh, for drain bolt)
  • Spray cleaner/degreaser
  • Torque wrench
  • Correct stand (flat lift, not traditional triangle stand)

Steps to Change the Oil

  1. Warm Up the Bike
    Start and idle the bike for a few minutes to reach operating temperature. This allows oil to flow and drain more completely.
  2. Prepare the Workspace
    Place the bike on a flat lift stand. Do not use a standard triangle stand, as it can block access to the drain bolt and inhibit full draining. The correct stand also helps when tilting the bike to aid drainage.
  3. Remove the Skid Plate (if equipped)
    If your bike has an aftermarket skid plate, remove it for easy access to the drain plug and oil filter cover.
  4. Remove the Oil Filter
    Locate the oil filter covertypically secured with two 8mm bolts. Use the 8mm T-wrench to remove these bolts and the cover.
    • If the filter is stuck, gently use needle nose pliers to pull it out.
  5. Drain the Oil
    Place your drain pan under the engine. Remove the drain bolt (usually 13mm) and allow oil to fully drain.
    • Watch for the crush washer on the drain bolt; replace with a new one if available to prevent leaks.
  6. Inspect and Clean the Oil Screen
    The 2022 EC 250 features an oil screen near the drain plug. Remove, clean thoroughly with spray cleaner, and check for any metallic debris. If present, monitor for engine issues.
  7. Clean Surfaces and Inspect O-rings
    Clean all sealing surfaces for the drain plug, oil filter cover, and oil screen. Inspect O-rings for flattening or damage and replace them if necessary.
  8. Reinstall Drain Plug and Oil Screen
    Lightly oil the O-rings before reinstallation. Thread the drain plug and oil screen back in by hand to avoid cross-threading. Tighten the drain plug to a recommended specification of 14.8 ft-lb (20 Nm) using a torque wrench, if available.
  9. Install New Oil Filter
    Insert the new oil filter with the correct orientation (open end facing out, typically). Refit the filter cover and tighten the bolts evenly to avoid warping the cover.
  10. Refill Engine Oil
    Add the specified type and amount of engine oil recommended in your owner's manual. A funnel is helpful for a clean fill.
  11. Double Check for Leaks
    Wipe down the engine, start the bike, and let it idle. Inspect for oil leaks at the drain plug and filter housing.
  12. Properly Dispose of Old Oil and Filter
    Take engine oil and filter to a recycling center or designated oil collection point.

2022 GAS GAS EC 250 Specific Call-Outs

  • Stand Selection: Gas Gas (– and KTM/Husqvarna siblings) require a flat lift stand for unobstructed access to the drain bolt. Using an incorrect stand can cause incomplete oil draining—or worse, stripped threads.
  • Oil Screen Inspection: Unlike some older bikes, the EC 250's oil screen must be cleaned at each change. Missing this step can lead to oil restriction or critical engine wear.
  • O-ring Maintenance: Always inspect drain, screen, and filter cap O-rings. Replace at the first sign of flattening to prevent leaks.
  • Correct Oil Volume & Type: Double-check your owner's manual (the 2022 EC 250 shares much of its maintenance with 2023 EC/MC 250 models—when in doubt, confirm both quantity and grade).
  • Crush Washer: Always replace the crush washer on the drain bolt to avoid leaks after reassembly.
  • Torque Values: Proper torque for drain plug and oil screen is critical—do not over-tighten or threads may strip; use 14.8 ft-lb (20 Nm).
  • Aftermarket Skid Plates: Remove if necessary for full access, as they can block both the bolt and the drainage path.

Final Tips

  • Always use high-quality engine oil specifically formulated for modern two-stroke or four-stroke off-road motorcycles, as required for your model.
  • Replace the oil filter at every oil change, not every other one, for optimal protection.
  • Log all maintenance for warranty and resale value.
