Mileage can vary widely depending on a number of facotors. I get 24 mpg on the hwy, 17 mpg around the city, and 12 mpg on the track. "Spirited" street driving can easily yield 14-16 mpg.

A Mini Cooper S should be somewhat slower than your Boxster S. I have a base Boxster and a 2002 MCS with the JCW supercharger upgrade to 200hp and my base Boxster will stilll outrun the MCS.

Do a search on oil recommendations and you'll find several very long and quite passionate threads on the subject.

The RMS leak isn't an issue if you can live with it. Just make sure that the oil lever doesn't get too low.
