Using your DC Sports Red Magnetic Drain Plug is easy. First, make sure your engine is cool. Unscrew the old drain plug and replace it with the new DC Sports plug. Hand-tighten it first, then use a wrench to give it a final gentle turn. Don't over-tighten as it can damage the threads. Check the plug regularly for debris buildup. If you notice a lot of debris, it might be time to change your oil. To maintain your plug, clean it with a soft cloth after each oil change. This will keep the magnet strong and the plug in good condition.
