For arguements sake, let's say premium is $1 / gallon more expensive than regular. A fill-up will cost you a whole $15 more for premium. If you're scraping to save $15 once or twice a mo, a Boxster may not be the proper vehicle for you.

Where we live SoCal, and usually the difference between Premium and Regular is about $5 (max) per tank, and needless to say, we always use Premium in all the cars..
