Thanks Marty and MIJ. I have come to the conclusion that Klaus was on the money when he suggested I get a pack of crush washers. I don't believe I have ever had a car with an aluminum crush washer, unless the old beetle had one (long time ago). Marty's comments were interesting, because I have had several cars with copper washers, which I mostly did not replace. I never had a problem. But I have already had two instances on the 850T of the plug loosening up a bit after reusing an aluminum crush washer. Now that I cleaned the pan and retightened the plug, the pan is staying dry (this happened once before). I wonder if the temperature is higher than my other cars due to the turbo, causing the plug to loosen up when reusing the washer. In any event, I think I'll follow Klaus' suggestion and be prepared for my oil changes. Thanks to all you folks for helping me - I have enough issues without creating more.
