Changing the oil in your 2018 Husqvarna FE350HQ is crucial for engine longevity and optimal performance. This detailed how-to guide, proprietary to MotoSport.com, will walk you through each step, highlight special notes for this model year, and list all the tools and parts you'll need for a successful oil change.

Tools and Supplies Needed

  • Triangle stand or paddock stand
  • Drain pan
  • Half-inch (13 mm) wrench and socket (for drain bolt)
  • 8 mm socket (for filter cover)
  • Needle nose pliers (for oil screen removal)
  • New oil filter (OEM recommended)
  • Engine oil (approx. 1.1 quarts, check your manual for type/grade)
  • Oil fill funnel
  • Clean rags/paper towels
  • Contact cleaner (optional)
  • Measuring cup (for precise oil fill)

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start and let the bike idle for 1-2 minutes. A warm engine allows the oil to flow and drain more thoroughly.
  2. Stabilize the Bike
    • Place the bike upright on a triangle or paddock stand. Make sure it–s secure and level.
  3. Remove the Drain Plug
    • Place a drain pan underneath the engine area.
    • Use a 13 mm deep socket to loosen and remove the oil drain bolt. Allow all old oil to empty into the pan.
  4. Remove and Clean Oil Screen
    • Use needle nose pliers to pull out the oil screen (accessed near the drain bolt).
    • Clean the screen thoroughly using contact cleaner or a suitable solvent.
  5. Remove the Oil Filter Cover
    • With an 8 mm socket, remove the two bolts on the oil filter cover located on the right side of the engine.
    • Pull the cover away carefully; some oil may spill, so have rags handy.
  6. Replace the Oil Filter
    • Remove the old oil filter. Install a new, properly oiled filter. Double-check it clicks fully into place.
  7. Reinstall Oil Screen and Drain Plug
    • Place the cleaned oil screen back in its position.
    • Reinstall the drain bolt. Tighten securely, but do not overtighten to avoid stripping the threads.
  8. Install Oil Filter Cover
    • Position the filter cover and fasten the bolts snugly with the 8 mm socket.
  9. Refill New Oil
    • With the bike standing upright, insert a funnel into the oil filler opening.
    • Pour in 1.1 quarts of the manufacturer-recommended oil. Use a measuring cup for accuracy.
    • Replace the oil cap and wipe away any spilled oil.
  10. Check Oil Level
    • Stand the bike straight and check the oil level through the inspection window or dipstick.
    • Add oil incrementally if necessary; avoid overfilling.
  11. Start and Inspect
    • Start the engine and let it idle for 1-2 minutes.
    • Check for leaks around the drain bolt, oil screen, and filter cover.
    • Re-check oil level, topping up as needed.

Specific Model Notes for the 2018 Husqvarna FE350HQ

  • The 2018 FE350HQ shares engine architecture with the FC/FX 350s but is tuned for enduro. Oil capacity and locations of drain plug, oil screen, and filter remain consistent with sibling models. Always verify with your owner—s manual for torque specs and any minor updates for the FE model line.
  • This engine holds 1.1 quarts of oil.
  • Always use an oil filter designed for the FE350HQ for proper fit and oil pressure maintenance.
  • The lower frame guard may need to be loosened or removed on certain enduro trims for easier access to oil drain and screen bolts.
  • Replace drain plug and oil screen O-rings if worn or damaged to avoid leaks.
  • After first oil change on a new engine, inspect for any metallic debris as it can signal break-in wear or potential issues.

Maintenance Tips and Intervals

  • Change oil every 10-15 hours of riding or as specified in your manual.
  • Use only high-quality, motorcycle-specific synthetic or semi-synthetic oil.
  • Keep a maintenance log for oil changes, filter replacements, and model-specific notes.
