Diesel was at $2.77 a gallon at QT in west Phoenix yesterday. I just couldn't bring myself to buy it though. The last two times I bought fuel there my mileage dropped between 2 and 3 mpg! I paid a little more at the station across the street, and have been getting my regular mileage.

 

I always fill up at the QT at I-10 and 51st Ave. I never have had a problem with mileage. Even after switching from Flyin' J.
