Do-it-yourself oil changes save you money, but they can be messy. Common problems include dropping the drain plug in dirty oil or losing the slippery little devil on the garage floor. One solution is the Drain Plug Pro from OTC Tools. Once loosened, the highly magnetized flexible end of the unit locks onto the bolt from practically any angle, keeping your hands away from the oil. The plug is then removed by twisting the tool as if you were unscrewing a bolt. When the oil pan is empty, you reverse the process and tighten before refilling with new oil. The Drain Plug Pro retails for $20, but online resellers on www.amazon.com sell for less. Get product details at www.otctools.com.
