Regularly changing the oil in your 2025 Husqvarna TC250 is critical for keeping your dirt bike in top condition. This walkthrough gives you a proprietary, step-by-step guide trusted by MotoSport.com to get the job done right, highlighting specific callouts for your model year.

Tools & Supplies You’ll Need:

• Tusk or OEM Oil Change Kit (includes oil filter, crush washer, and filter O-ring)
• Factory-recommended transmission oil (Motorex or other as per manual)
• Measuring cup (0.7 liters capacity recommended)
• Drain pan for used oil
• 8mm and 13mm sockets/wrenches (confirm with your owner’s manual)
• Torque wrench
• Small funnel or the Motorex oil bottle with pour spout
• Contact cleaner
• Rags or paper towels
• Gloves
• Optional: service stand

Before You Begin (TC250-Specific Notes):

• The 2025 TC250 uses a 0.7-liter oil capacity in the transmission. Always check your owner’s manual for model-year confirmation, as capacities can change.
• Oil is filled until it just starts to weep from the check-level hole on the side of the engine case.
• Never overfill. Overfilling can cause increased clutch drag and foaming of the oil.
• This model uses a crush washer under the drain bolt; replace it every oil change to prevent leaks.

Step-by-Step Oil Change for Your 2025 Husqvarna TC250

• 1. Warm Up the Engine
  Briefly start and idle your TC250 for 3-5 minutes to warm up the oil – this helps suspends debris and allows for a more complete drain.
• 2. Position Your Bike
  Place the TC250 upright on a service stand in a well-ventilated area.
• 3. Remove the Oil Filler Cap and Drain Bolt
  With gloves on, place your drain pan under the engine. Remove the oil filler cap to allow air in. Next, use the 13mm wrench/socket to remove the drain bolt and washer at the bottom of the engine.
  Pro Tip: Tilt the bike slightly toward the drain side to help empty the last bit of oil.
• 4. Remove and Inspect/Replace the Oil Filter
  Locate the oil filter cap (typically held with 8mm bolts). Remove it and pull out the oil filter. Inspect the filter for metal shavings or signs of excessive wear. Always replace with a new OEM or equivalent filter.
• 5. Clean and Prep
  Wipe down the drain bolt, fit a new crush washer, and clean the mating surface of the oil filter cover. Inspect the O-ring and replace if damaged or brittle.
• 6. Reinstall Drain Bolt and Oil Filter
  Torque the drain bolt to spec (usually around 15 Nm, check your manual). Install the new filter and reattach the cap, tightening bolts evenly and to the torque specification.
• 7. Add New Oil
  Using a measuring cup, pour in 0.7 liters of high-quality transmission oil as recommended by Husqvarna. Use a funnel if necessary.
  TC250 Call-Out: Fill until you see oil begin to seep out of the check-level screw hole on the right side of the engine. Reinstall the screw immediately when this appears.
• 8. Reinstall Filler Cap and Cleanup
  Replace the oil filler cap snugly. Use contact cleaner and rags to wipe away any oil spills.
• 9. Start and Inspect
  Start the bike and let it idle for a minute. Inspect for leaks at the drain bolt, oil filter cover, and filler cap. Shut off and check the oil level using the sight glass or check screw once more, adding oil as needed.
• 10. Dispose of Used Oil Responsibly
  Transfer the old oil into a sealed container and take it to your local recycling center.

2025 Husqvarna TC250 Oil Change Model-Specific Callouts

• The 2025 TC250 continues to use the horizontal split engine cases with a sight glass and a check-level screw. Oil fill and check procedures remain unchanged from 2024.
• Factory recommended oil is Motorex Cross Power 2T 10W/40 or similar quality gear oil.
• Be sure to install a fresh crush washer on the drain bolt every service.
• Always check for software updates or TSBs via Husqvarna's official service portal before your first oil change on a new production year.
• If you notice milky or frothy oil, consult your dealer, as this may indicate a bad seal and coolant mixing with the oil.

Final Notes

• Change oil every 10-15 engine hours, or sooner with hard or muddy riding.
• Over-tightening the drain bolt or cover screws can damage the engine case – always use a torque wrench.
• If you’re new to dirt bike maintenance, consider watching a detailed TC250 oil change video for reference.
