Regular oil changes are critical to keep your 2022 GAS GAS EX 350F running at peak performance and to extend the life of your engine. This detailed guide by MotoSport.com will walk you through the process step-by-step, highlight necessary tools, and call out any model-specific considerations for your dirt bike.

Tools & Materials Needed

  • Oil drain pan
  • 13mm socket and ratchet
  • Torque wrench
  • Needle nose pliers
  • Measuring cup
  • T-handle or Allen wrench (check for oil filter cover compatibility)
  • New oil filter
  • New crush washer
  • Contact cleaner
  • Clean rags or paper towels
  • Funnel
  • Motorex Cross Power 4T 10W-50 oil or manufacturer-recommended
  • Grease (for sealing surfaces)

Preparation

  • Start with a warm engine. Let the bike idle for a few minutes or take a quick ride. Warm oil will drain more thoroughly, carrying away more contaminants.
  • Park your bike on a stable, level surface and ensure the engine is off. Allow a few minutes for the exhaust and engine to cool slightly, but avoid a cold oil change.
  • If your model has an ignition key or remote start, confirm the ignition is off for safety.

Step-by-Step Oil Change Guide

  • Gather Your Tools and Supplies
    Lay out all tools, oil, filter, and drain pan so you don't have to hunt down items mid-change.
  • Remove Skid Plate (if equipped) and Set Up Drain Pan
    If your EX 350F has a skid plate, remove it for easier access to the drain plug and filter.
  • Drain the Oil
    • Locate and loosen the main drain plug (13mm bolt) beneath the engine, directly under the crankcase.
    • Remove the drain plug and allow oil to flow into your pan. Be careful, oil may be hot.
    • Check that the crush washer comes off with the plug. Replace with a new one to ensure a proper seal before reinstallation.
  • Remove and Clean the Oil Strainer
    • Locate the oil strainer bolt, usually near the drain bolt.
    • Remove the strainer bolt with a 13mm socket, then use needle nose pliers to carefully extract the strainer mesh.
    • Clean the mesh screen thoroughly with contact cleaner and ensure no debris or old oil remains. Replace if the screen is damaged.
  • Remove and Replace the Oil Filter
    • Find the oil filter cover, typically secured with a T-handle or Allen bolts.
    • Remove the cover and take out the old oil filter. Note its orientation.
    • Install a new oil filter, making sure it sits properly in its recess. Lightly coat the filter's edge with fresh oil for a leak-free seal.
    • Clean the cover gasket or replace it if worn.
  • Install Cleaned Strainer and New Crush Washer
    • Reinstall the strainer and replace the washer on the bolt. Torque to manufacturer–s spec (check your manual; typically 15 Nm for drain plug, but always verify).
  • Add New Oil
    • Add Motorex Cross Power 4T 10W-50 oil or equivalent. The 2022 GAS GAS EX 350F takes approximately 1.1 liters (1.16 US quarts) of oil, but always double-check your owner’s manual for exact quantity.
    • Pour slowly using a funnel to avoid overfilling. Check oil level with the sight glass or dipstick depending on your bike’s design.
  • Start the Engine & Inspect
    • Start the engine and let it idle for thirty seconds. Check for leaks at the drain bolt, strainer, and filter cover.
    • Shut the engine off and allow the oil to settle. Re-check the oil level and top off if necessary.
  • Clean Up & Dispose of Old Oil Properly
    • Wipe down any drips from the crankcase, reinstall the skid plate, and dispose of used oil and filter at a recycling facility.

Model-Specific Tips for the 2022 GAS GAS EX 350F

  • The drain bolt and strainer locations on the EX 350F are very similar to other 350cc KTM and Husqvarna models. The oil change method and filter design are nearly identical, which streamlines supplies and procedure across brands. However, always refer to your owner’s manual for torque specs and quantities to avoid over tightening or overfilling your bike. Incorrect torque can damage threads in the soft aluminum engine case.
  • Regularly inspect both the crush washer and filter cover gasket each change — replacing as needed for the best seal.
  • If you ride in extreme conditions or competitively, consider using the high end of recommended oil change intervals, or change oil even more frequently than every 15 engine hours.
  • The GAS GAS EX 350F shares its platform with KTM and Husqvarna 350 models, so universal tool kits and parts listed above will work across these brands.

Extra Pro Tips

  • Tilt the bike slightly side-to-side after draining to clear any remaining oil from corners of the crankcase for a more complete oil change.
  • Use a dab of high-quality grease on the new strainer and drain plug threads to aid future removal and prevent leaks.
  • Always keep a spare oil filter, crush washer, and a liter of recommended oil in your garage to make regular maintenance easy and quick.
  • If you are unfamiliar with torque specs or lack a torque wrench, consult your dealer or service center, or seek help to avoid costly mistakes.

Conclusion

Changing the oil on your 2022 GAS GAS EX 350F is straightforward with the correct tools and method.
