[boxfix]

I get my 15W 50 Mobil 1 Synthetic from WalMart on line from their website.

$25.47 for 5 qt. bottle......FREE SHIPPING - 2 day on orders over $50.00......I usually buy 4 at a time for the Boxster and my Saab turbos.

So a Boxster oil change with filter will cost $60.00.

Oil changes are very easy as outlined here.

Enjoy the car.
