Here in Denver, I think I paid 2.13 this morning for midgrade after a 6 cent/gallon discount at Safeway (every time you buy over $50 ? bucks in groceries, they give a $.06 per gallon discount, or a $.03 per gallon discount anytime for members (and their prices are already lower. (that was also before I got responses and did research on 85 vs 87 octane gas). I'll be going w/85 next time. I think that'll put me at $2.03 or $2.06 per gallon.
I am getting about 16mpg after my 1st tank in city driving.
