Well I've been watching the gas gauge lately, and what with premium costing about $4/gal here in LA.
I immediately saw the oil companies switch to summer blended fuel two weeks ago, when I checked out my mpg, I was averaging 23 mpg last month, now I'm squeaking out 18 mpg, WTF!!!

Anybody else watch you mpg and see similar results here in California? I know Arizona has some high quality fuels compared to us. It really sucks having to pay almost $4, but it really hurts when you have to pay more and get less...
