Thanks all.  Not the first - let's just say we will no longer "fit" in in my car.

New fill is a drop. I decided to stop going to the same station/pump all the time. I did that for more precision in MPG calculations. But I want to chase the cheaper prices on my commute. Seems the Costco pump is significantly different than the one I normally use. Also, it is E10 gasoline. Yuck. But the price was $0.22 cheaper than my usual station. Still, since Costco was only $0.04 cheaper than the cheapest station I see on my route, maybe I should buy at that Chevron if they don't have the E10?
What's better E10 for $3.75/gal or straight gasoline for $3.79/gal? (Pretty insignificant, huh?)

E10
I am no expert, but I would guess the E10 would yield lower MPG's thus offsetting the 0.04 cost difference?

Theoretically, and in my experience, E10 is about 3% lower.

based on Palemelanesian's experience that e10 yields 3% less mpg...
based on your average of 60mpg's
im calculating that E10 at $3.75/gal (58.2mpg) costs you $0.064 per mile
Straight gas at $3.79/gal (60mpg) costs you $0.063 per mile |

I saw instant MPG number climbing an extended hill in fifth tonight that suggest I could be seeing much more than 3%, but that I am definitely seeing reduced FE with this gasoline. The Costco marked the pump as E10. Is that the law? Because the Chevron I stopped in at tonight didn't have any markings on the pump and the attendant did not know if that meant the gas was ethanol free. Anyone know if law requires labeling ethanol-mixed gas at the pump?

I'm not sure about the actual "law," but i do notice that i always see pumps at the regular gas stations stating that the gas can contain up to 10% ethanol. Which leads me to believe that not many gas stations in socal contain "straight gas."
I guess Costco is just more honest about thier e10 ratings. |

Yup, you seem to be close to the facts, jedi. A little searching suggests that all Cali gas might have 5.7% ethanol and that CA does not require labeling at the pump (or at least probably did not as recently as 2010).
