Oil-change considerations

To perform an oil change, you’ll typically need a 14mm socket or wrench, a replacement sealing washer if required, an oil catch pan, and fresh oil as recommended by Honda for your engine.
Using the correct tools and parts helps prevent cross-threading, leaks, and damaged threads during the drain and refill process.
Reinstallation and safety tips
When reassembling, avoid overtightening the drain plug and ensure any washer is properly seated. Follow the manufacturer’s torque specification to maintain a proper seal and prevent leaks; consult the owner's manual for the exact value applicable to your VIN.
