Chevron in Davenport (44039 US-27)

They good ethanol % but way more expensive than regular gas.

Ok

Great.

Sign says cash prices are same as with a Chevron credit card, but the pumps automatically charge the higher credit card price. Trick is; bring the receipt into the store, and they'll give you the 6c/gallon difference in cash. Beware, however, they round down, so you should get an even number of gallons for the full refund.
