Keeping the oil in your 2018 Husqvarna FC250 fresh is essential for engine longevity and peak performance. This guide, proprietary to MotoSport.com, covers everything you need to know, including required tools, step-by-step instructions, and specific call-outs for this model.

Tools and Supplies Needed

  • 13mm deep socket and ratchet (for drain plug and oil screen)
  • 5mm Allen wrench (for oil filter cover)
  • Drain pan
  • New oil filter (Husqvarna OEM part 77338005100 or quality aftermarket equivalent)
  • Fresh engine oil (refer to your owner's manual for weight and type; generally 15W-50 synthetic for the FC250)
  • New copper crush washer (recommended for proper sealing)
  • Clean rags or paper towels
  • Parts cleaner/contact cleaner
  • Pin wrench (for oil screen removal; optional but recommended)
  • Torque wrench (for proper bolt tightening)
  • Measuring cup (to refill the oil accurately)
  • Latex/nitrile gloves (to keep your hands clean)

Step-by-Step Oil Change Guide

  1. Warm up the engine.
    • Start the FC250 and let it idle for a few minutes. This allows the oil to thin and drain out completely.
  2. Stabilize the bike.
    • Park the motorcycle on a level surface using a bike stand. Turn the ignition off and let the engine cool just enough to be handled safely (oil should still be warm).
  3. Remove the skid plate (if installed).
    • Some FC250s have an aftermarket skid plate; remove it to access the drain bolts easily.
  4. Drain the engine oil.
    • Place the drain pan below the engine.
    • Using the 13mm socket, remove the main drain plug (located on the bottom of the engine). Be careful—the engine and oil may be hot.
    • Let oil drain until the flow is a slow drip.
  5. Inspect and clean the magnetic drain plug.
    • Examine the drain plug's magnet for metal debris. Wipe it clean before reinstalling.
  6. Remove and inspect the oil screen.
    • Locate and carefully remove the smaller bolt (also 13mm) with an integrated oil screen (may require a pin wrench).
    • Pull out the screen and clean it with parts cleaner. Inspect for any metal particles—some residue is normal, but excessive metal is a red flag.
    • Replace the screen and its O-rings if damaged.
  7. Remove and replace the oil filter.
    • Use a 5mm Allen wrench to remove the oil filter cover on the side of the engine.
    • Take out the old filter and install a new one, ensuring it seats fully.
  8. Replace the drain plug and oil screen.
    • Install a new copper crush washer on the main drain plug for a proper seal.
    • Thread the plug in by hand to prevent cross-threading, then tighten to the manufacturer's torque spec (consult your owner's manual for final settings).
    • Do the same for the oil screen bolt.
  9. Fill with new engine oil.
    • Remove the oil fill cap (on the top right of the engine) and pour in the recommended type and amount of oil. The 2018 FC250 typically takes about 1.1 liters, but always double-check your manual.
  10. Check the oil level.
    • With the bike upright (not on a side stand), check the oil level sight glass or dipstick. Add a small amount if necessary.
  11. Inspect for leaks.
    • Start the engine and let it idle for 2-3 minutes. Shut off and check all around the drain plug, filter, and screen for leaks. Add oil if the level drops after circulating.
  12. Dispose of old oil and filter properly.
    • Recycle used oil at a designated recycling center. Do not pour it down drains or on the ground.

Specific Call-outs for the 2018 Husqvarna FC250

  • The drain plug on this model is magnetic to help capture metallic shavings; always inspect and clean thoroughly.
  • Oil screen location: The FC250 features a bolt with an integrated oil screen on the lower part of the engine—be meticulous with cleaning this screen and ensure the O-rings are in good condition for reassembly.
  • Torque specifications: It is essential to use a torque wrench and follow the manufacturer's recommended settings for all bolts to prevent stripping the aluminum cases. Over-tightening can lead to expensive repairs.
  • Oil capacity: The typical refill requires around 1.1 liters of oil. Overfilling can cause engine damage or excess crankcase pressure—measure accurately.
  • Change intervals: For off-road riding, change oil at most every 10–15 hours of engine use, or more frequently if racing or riding in extreme conditions for optimal engine health.
