This proprietary MotoSport.com guide will walk you through a robust and reliable oil change process for your 2022 GAS GAS EC350F. Regular oil changes are essential for the health and longevity of your dirt bike's engine, and this model has several unique characteristics owners should be aware of. Follow these steps to ensure you get it right every time.

Tools and Supplies Needed

  • 8mm T-wrench (Torx or Allen, as needed by your fasteners)
  • 8mm Allen wrench
  • 13mm ratchet or wrench
  • Needle-nose pliers
  • Oil filter (model-specific)
  • Quality engine oil (specification per your owner's manual)
  • Drain pan
  • Rags
  • New crush washers and O-rings (as needed)
  • Torque wrench
  • Stand (bike stand that allows access to the drain bolt)
  • Parts cleaner (for oil screen and sealing surfaces)

Model-Specific Call-Outs for the 2022 GAS GAS EC350F

  • The oil drain bolt is difficult to access with standard stands; use a side-stand or special stand that allows clear access to the drain bolt for proper drainage and bolt removal.
  • This bike is part of the larger KTM/Husqvarna Group platform, so tips for those brands (250cc and 350cc) often cross-apply.
  • Always inspect the oil screen for metal shavings while cleaning. The screen sits in a specific groove—incorrect installation can cause oil bypass and engine damage.
  • Torque your drain plug to the manufacturer spec (14.8 ft-lbs recommended).
  • If the O-rings or any sealing surfaces show wear or damage, replace them immediately to avoid leaks or pressure loss.
  • Always turn the ignition off before performing any maintenance.

Step-by-Step Oil Change Instructions

  • Warm up your engine: Start your bike and run it for a few minutes to warm the oil, allowing it to drain more thoroughly. Then switch off the engine and make sure the bike is stable and secure on a compatible stand.
  • Remove the skid plate or any guards blocking the oil drain bolt, if necessary.
  • Position the drain pan: Place it squarely under the engine to catch old oil.
  • Remove the oil drain bolt: Use the 13mm wrench/ratchet to unscrew the drain plug. Remove the crush washer and be prepared for a rapid flow of hot oil. Let the oil drain fully. Use caution—the oil will be hot.
  • Remove the oil filter: Locate the filter cover. Using your 8mm T-wrench, remove the bolts holding the filter cover in place. Carefully remove the cover and the filter. If the filter is stuck, gently use needle-nose pliers to wiggle it free. Place the old filter aside.
  • Clean the oil screen: With the oil draining, find and remove the oil screen (often located near the drain bolt). Clean the screen using parts cleaner and inspect for any metal debris. Replace it if damaged. When reinstalling, make certain the screen sits properly in its groove to prevent oil bypass.
  • Inspect and replace O-rings/crush washers: Inspect the O-rings on the filter cover and the drain plug. If any are flat, cracked, or worn, replace them immediately.
  • Install new oil filter: Lubricate the new filter's O-rings with a dab of fresh oil. Insert the filter into the housing, ensuring it sits evenly. Reattach the cover and tighten bolts to the manufacturer's torque spec–avoid over-tightening.
  • Reinstall drain plug and screen: Refit the cleaned screen and ensure it's properly aligned. Install a new crush washer on the drain plug and thread it in by hand. Torque to 14.8 ft-lbs using a torque wrench.
  • Add new oil: Remove the oil filler cap and pour in the recommended volume and specification of oil (check your owner's manual for exact requirements; commonly 1.25–1.3L for the EC350F). Let it settle, then check the sight glass or dipstick to confirm proper level.
  • Check for leaks: Start the engine and let it run for a minute. Shut off and check for leaks at the drain plug, oil filter cover, and around the screen cap. Top off the oil if necessary after the engine has run and filled the filter.
  • Dispose of old oil and filter properly: Take them to your local recycling or waste facility—never dump old oil.

Tips & Additional Recommendations

  • Leaning the bike slightly toward the drain plug as oil drains can help clear the last of the old oil from the sump. Some riders hit the starter with the kill switch engaged to “pulse” a little more oil out—do this only for a second or two as excess cranking without oil isn't good for internal parts.
  • Be methodical: Keep all removed parts organized and double-check every bolt before riding.
  • If you notice significant metal in the oil screen or abnormal oil color, consult a technician for further diagnostics.
  • Review your service interval schedule and always use oil that meets the manufacturer's requirements.
