Keeping your 2024 Husqvarna TC 65 in top racing condition means performing regular maintenance—one of the most important is changing the engine oil at the right intervals. This step-by-step guide walks you through the recommended tools, the process, and shares model-specific tips every TC 65 owner should know. This proprietary guide is brought to you by MotoSport.com.

Tools & Supplies Needed

  • 10mm socket or wrench for drain bolt
  • Drain pan for capturing used oil
  • Rag or shop towels for cleanup
  • Funnel for pouring new oil
  • Torque wrench (optional, but recommended for drain bolt)
  • Replacement O-ring for drain bolt (optional, if O-ring is worn)
  • 500ml of 15W-50 4T engine oil (like Motorex or Motul, as recommended in the manual)
  • Gloves to keep hands clean
  • Small pick or screwdriver (to remove stuck O-ring, if necessary)

Recommended Oil & Service Interval

  • Oil type: 15W-50, high-quality 4-stroke engine oil
  • Capacity: 500ml for the TC 65 – double-check your owner’s manual
  • Interval: Every 5–10 hours of riding, sooner for heavy-use or racing. The manual typically recommends every 10 hours, but many riders change more frequently for optimum protection.1

Step-By-Step Instructions

  1. Warm Up the Engine
    • Start the bike and let it run for 2–3 minutes. This warms the oil, helping it drain more completely and carry away contaminants.
  2. Stabilize and Prep the Bike
    • Turn off the engine. Place the bike upright on a stand for stability.
    • Wipe dirt and debris away from the drain bolt area and the oil fill cap (usually marked "oil"). A clean area prevents contamination.
  3. Remove the Oil Drain Bolt
    • Position the drain pan beneath the engine’s drain bolt, found on the underside near the engine case.
    • Using a 10mm socket or wrench, loosen and remove the drain bolt. Allow all oil to drain completely—this may take a few minutes.
    • Inspect the O-ring on the drain bolt. If it’s damaged or flattened, replace it immediately. Keeping an extra on hand is wise.
  4. Reinstall the Drain Bolt
    • Once the oil flow slows to a drip, clean the bolt and the sealing surface on the engine case.
    • Install a new O-ring if needed, then hand-tighten the drain bolt.
    • Tighten using a torque wrench to manufacturer spec (typically 10 Nm—but always verify with your TC 65 manual).
  5. Add New Oil
    • Remove the oil fill cap, located on the right side of the engine near the clutch cover.
    • Place the funnel in the oil fill hole and slowly pour in 500ml (0.5L) of 15W-50 oil.2
    • Allow a minute for the oil to settle. If your bike has a sight glass, check oil level and adjust as needed.
    • Reinstall and tighten the oil fill cap securely.
  6. Check for Leaks & Final Steps
    • Start the engine and let it run for 30 seconds to circulate the oil.
    • Check underneath for leaks at the drain bolt.
    • Shut the engine off, wait a minute, and double-check the oil level—top up if necessary.
    • Dispose of used oil responsibly, taking it to a recycling center or approved collection site.

Model-Specific Call-Outs for 2024 Husqvarna TC 65

  • Oil Capacity: The 2024 TC 65 strictly uses 500ml of 15W-50 oil. Overfilling can cause engine damage or leaks—always measure precisely.2
  • O-Ring Health: The O-ring on the drain bolt is essential for a proper seal. Replace if you see any nicks, cracks, or flattening.
  • Interval Reminder: Race conditions or muddy riding may call for oil changes every 5–7 hours instead of 10.
  • Manufacturer’s Oil: Use premium 15W-50 meeting Husqvarna/KTM standards. Popular choices are Motorex or Motul.
  • Filter Note: The TC 65 does not have a separate, replaceable oil filter—oil changes are the primary means of engine lubrication maintenance.1

Pro Tips from MotoSport.com

  • Dispose of Used Oil Responsibly: Never dump used oil in the trash or on the ground. Take it to your local auto parts store or a dedicated recycling facility.
  • Keep a Maintenance Log: Track every oil change by date and hours ridden for warranty and resale value.
  • Stock Extra O-Rings: Save future headaches by buying a pack of drain bolt O-rings—tiny, but critical.
  • Wipe As You Work: Cleanliness is the key to keeping grit and debris out of your engine. Always wipe surfaces before opening any caps.
