[BoxsterSteve]

I'm not certain of the service history of my 2000 Boxster S, so I'd like to change out all fluids starting with the transmission fluid.

I've used the search function, but can't find info I need.

Would Mobil Delvac 75w90 Synthetic Gear oil be an acceptable choice, or should I use factory fill gear oil from the nearest (1.5 hours away) stealership?

Any thoughts & commentary appreciated.
