I've been using 87 octane for the past 7,500 miles in my Avalon Hybrid and been getting a steady 41-42 mpg. But I decided to use regular fuel, 85 octane (81, 83 and 85 are marketed as regular in Colorado in different parts) instead of paying 30 cents more for 87 octane. Interestingly on my first tank I got 48.0mpg. I don't know if this is just a fluke or if I actually got better fuel mileage just yet. I guess I'll find out next week at my next fueling.

EDIT:
Never mind. I just redid the numbers and got 41.1 mpg.
