Start with the Prius FAQ to make sure you're optimized for performance. Don't worry about the 'dealer tank' but treat it as 'practice gas.' When you get low, fill up with something like Shell or other high energy gasolines. If you are in an ethanol area, check out the thread about E30 testing.

GOOD LUCK!
