This weekend I tried installing a Fumoto oil drain valve in my '97 900 (F106, for those interested). It's a very slick design, much nicer than the Fram SureDrain I've had on the car for over a year. The problem was when it was all tightened up, the drain lever was facing straight down so if I was to accidentally drive over something high, it would push the lever back and drain my oil! If the threads were just a little different it would have been perfect. I'd be interested to hear if anyone else has put one on and in what orientation their lever was in. For now, though, the car has the SureDrain back on.
