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?)
