I've done oil changes on all the cars I've owned, and after the local dealership overfilled the most recent change and didn't care, that is the last time they're touching my car.

So it's a 2005 Boxster with less than 24k. It's actually sat for almost 2 years now on a battery tender with occasional driving, but not much.

I'm working on an oil change but have run into some anomalies. One is that the drain plug looks like it's a torx instead of a hex. My 8mm hex got stuck in it, but a t-50 torx fits perfectly. When I look at the plug, it looks like it grooves cut for the torx. Second is that I can't find a crush washer--anywhere! Not on the drain hole, not in the oil, not on the plug. And it looks like it was leaking as there's a film of oil/dirt grime all over the underside of the car. Thoughts?
