Changing the oil in your 2015 Husqvarna FC350 is a critical maintenance task to keep your dirt bike running at its best.

This guide—brought to you by MotoSport.com—details the tools required, step-by-step procedure, and special notes specific to the 2015 Husqvarna FC350 so you can change your oil with confidence.

Tools and Supplies Needed

  • 13mm socket (for drain bolts)
  • 8mm socket (for oil filter cover bolts)
  • Half-inch wrench (alternative for drain bolt, optional)
  • Needle nose pliers (to remove the oil screen)
  • Oil catch pan
  • Clean rags or paper towels
  • New oil filter (specific to FC350)
  • Fresh oil (typically 10W-50 or as specified in your owner’s manual)
  • Measuring jug or cup
  • Funnel
  • Torque wrench (recommended for re-tightening bolts)
  • Contact cleaner (optional, for cleaning around oil fill and drain areas)
  • New crush washers (for drain bolts, recommended)

Step-by-Step Oil Change Procedure

  1. Warm up the engine
    Start your FC350 and let it idle for about a minute. Warm oil drains more easily and carries away more debris.
    Tip: Place your bike securely on a stand for stability throughout the process.
  2. Remove the skid plate (if equipped)
    This step provides easier access to the oil drain bolts.
  3. Position the oil pan
    Place your oil catch pan under the drain plug.
  4. Remove the main oil drain bolt
    Using the 13mm socket, unscrew the drain bolt located underneath the engine. Allow the oil to fully drain into the pan.
    Note: Be careful–the oil may be hot.
  5. Remove the oil screen and clean it
    Use needle nose pliers to gently extract the oil screen. Lay it on a clean towel and thoroughly rinse it with contact cleaner to remove trapped debris and sludge.
    Inspect for metal shavings as they could indicate wear.
  6. Remove the secondary drain bolt (if equipped)
    Some Husqvarna/KTM engines have a second drain bolt. Remove this with an 8mm or 13mm socket, allowing all residual oil to drain.
    Consult your owner’s manual for precise drain bolt locations.
  7. Lay the bike slightly on its side
    Carefully rock the bike to the side (using a stand or assistant) to help drain remaining oil from the case.
    Avoid excessive tilting to prevent spills.
  8. Install cleaned screen and replace drain bolts
    Reinstall the cleaned oil screen. Fit new crush washers to the bolts and reinstall them. Tighten to the manufacturer’s torque specifications (do not overtighten to prevent case damage) .
  9. Replace the oil filter
    Remove the oil filter cover using the 8mm socket. Pull out the old filter. Lightly oil the new filter, seat it firmly, and reinstall the cover.
    Ensure the filter is oriented correctly per factory specifications.
  10. Fill with fresh oil
    Remove the oil filler cap. Using your funnel, pour in the specified amount of new oil (the 2015 FC350 takes approximately 1.1 quarts or 1.0 liters–double-check your owner’s manual for capacity) .
    Use a measuring jug for accuracy.
  11. Check the oil level
    Set the bike upright and let oil settle for a minute. Inspect the oil level in the sight glass – it should reside near the middle of the glass when the bike is standing straight. Top off as needed .
  12. Reinstall the oil fill cap
    Ensure the cap seal is clean and intact, then snugly replace it.
  13. Wipe down and inspect for leaks
    Clean up any drips. Start the engine and let it idle for a minute. Turn the bike off and recheck for leaks at all seals and the drain bolt. Confirm the oil level is still correct, topping off if necessary .
