Paid $3.11 at Costco yesterday (just happened to pass by, never tried it before). Traffic was SO bad yesterday, we were literally sitting in traffic with the AC on in the X3. I reset the MPG counter to see how bad it could get in stop-and-go (more of the former). Wow, 8.1mpg by the time we passed that intersection.........

Prices are going down though! Now if I could just find a gas station that DOESN'T serve 10% ethanol gas.
