Keeping your 2020 Husqvarna FE350HQ running at its best relies on regular oil changes. This guide created exclusively for MotoSport.com outlines everything you need to know for a safe, clean, and correct oil change—hitting on model-specific tips to ensure smooth performance and durability.

Tools and Supplies Needed

  • 13mm socket or box wrench (for the oil drain plug)
  • 8mm socket or T30 Torx bit (to remove skid plate)
  • Drain pan (oil catch pan)
  • Measuring cup or graduated container (for precise oil amount)
  • Replacement oil filter
  • Fresh engine oil (consult manual for type and quantity; typically high-quality 4-stroke motorcycle oil)
  • New copper crush washer (for drain plug)
  • Rags or shop towels
  • Paper funnel
  • Small amount of grease (to lubricate O-ring)
  • Contact cleaner or degreaser (for cleaning parts)
  • Ratchet and extensions (as needed for access)
  • Safety gloves

Step-by-Step Oil Change Instructions

  1. Secure the Bike
    • Place the bike on a stable stand so it sits upright and you can easily access the underside. If using a side stand, have a helper steady the bike while loosening bolts to prevent accidental tipping and oil spills.
  2. Remove the Skid Plate
    • Take off the skid plate (bashplate) to fully expose the bottom of the engine. Use the 8mm socket or T30 Torx bit to remove the mounting bolts. Some plates have oil plug cutouts, but removing the plate makes the process less messy and allows you to clean it off.
  3. Position the Oil Drain Pan
    • Slide a drain pan directly under the rear of the engine where the drain plug is located. The plug is a 13mm hex head bolt with a copper washer—sometimes called a magnetic sump plug.
  4. Drain the Oil
    • With the engine still slightly warm (not hot), carefully remove the 13mm drain plug. Allow all used oil to fully drain.
    • Model-specific warning: Only remove the correct drain plug. There are several Allen-head plugs on the bottom of the FE350HQ—do not remove those, as they are not oil drains and could result in engine damage or component loss. The correct oil drain is the 13mm plug at the rear of the engine .
  5. Remove and Inspect the Oil Screen
    • The FE350HQ uses a magnetic sump plug and an oil screen in addition to the oil filter . Remove the oil screen, check for metal debris, and clean it thoroughly before reinstalling.
  6. Replace the Oil Filter
    • Remove the oil filter cover (consult the owner’s manual for exact location and bolt sizes). Pull the old filter out, noting orientation for reinstall. Replace with a new oil filter.
      If your oil change kit comes with O-rings, lightly grease them before installation for a better seal .
    • Reinstall the filter cover and tighten bolts to the specified torque (see your service manual for exact specs).
  7. Inspect and Replace Washers and O-rings
    • Always install a new copper crush washer on the drain plug. Lubricate any new O-rings with grease as recommended.
  8. Reinstall Drain Plug and Oil Screen
    • Reinstall the cleaned oil screen and drain plug using the new washer. Tighten the drain plug to the torque specified in your service manual (important to avoid cracking the case or leaks).
  9. Add Fresh Oil
    • Using a clean funnel, pour in the correct amount of fresh oil. For the 2020 FE350HQ, check your owner’s manual for oil capacity. Use a measuring cup for accuracy. Typically, it’s approximately 1.2 liters (verify for your model year and spec) .
    • Wait several minutes for the oil to settle, and check the level with the dipstick or sight glass, adding more as needed.
  10. Double-Check for Leaks
    • Visually inspect around the drain plug, oil screen, and filter cover to ensure no oil is leaking.
  11. Reinstall Skid Plate
    • Once satisfied everything is clean and leak-free, reinstall the skid plate securely.
  12. Start and Check Oil Level
    • Start the engine. Let it idle for a minute, then shut it off and let it sit for 1-2 minutes to allow oil to settle. Recheck the oil level, and top off if necessary.

Special Tips & Callouts for 2020 Husqvarna FE350HQ Owners

  • Magnetic sump plug and oil screen: Clean both at every oil change. The magnet helps catch metallic particles that indicate engine wear—examine carefully and consult a mechanic if you find significant metal.
  • Multiple plugs on engine bottom: Only the 13mm hex plug at the rear is for oil draining. Do NOT remove the other Allen-head plugs, as these retain other engine internals .
  • Frequent oil changes: Factory recommendations are every 15 hours for hard use or racing. Many riders change oil sooner to maximize engine longevity and performance .
  • Use correct oil type/quantity: Always use the oil grade recommended in your owner’s manual, and never overfill—excess oil can cause harm.
  • Dispose of old oil properly: Take used oil and filters to a recycling facility—never pour into the environment.

By following this MotoSport.com guide and referencing your Husqvarna owner’s manual, you’ll ensure your 2020 FE350HQ stays healthy and delivers the performance you expect. Happy riding.
