And I really don't worry about the Fumoto on the e38 since the drain bolt is protected by the little drop down access door...but on the e53...the plug is kind of exposed...so I worry about running over something and it getting caught on the release valve...then all of my oil drains from the engine!

Just an FYI for those not familiar with the Fumoto drain valve...see info below:

Install this valve and you can drain your engine oil without tools and without mess. Just lift the lever of this solid brass ball valve and give it a quarter turn to open it. Return the lever to its original position and it locks closed, double sealed to prevent leakage. The Engine Oil Drain Valve is made of corrosion resistant forged brass and stainless steel. The ball valve design provides a straight flow for efficient drainage and a perfect seal when closed. Frozen drain plug and stripped threads are eliminated forever.
