Filled up for $3.17 yesterday, but noticed that it jumped to $3.32 here overnight.
Gasoline without ethanol is widely available here......Casey's is usually where I get it, and it is rated at 87 octane.......gas with 10% ethanol is sold at the same price (at Casey's), but is rated slightly higher at 89 octane, and my vehicle (which has a "Flex Fuel" engine) gets slightly better mileage with the 10% mix.
Pure ethanol is also available around here (usually at QuickTrip or MFA stations), and generally sells for about thirty cents per gallon less than gasoline. I've used it a couple of times, and found that my gas mileage drops 40% on pure ethanol, therefore the cost savings simply don't come close to offsetting the reduction in mileage.
Strange as it may seem, there IS an engineering advantage to using a fuel with a small amount of ethanol. Basically, alcohol will absorb water, but pure gasoline won't. Therefore using a mix will ensure that moisture and condesation that forms in your fuel tank in winter, doesn't become a contaminant.......it is absorbed by the ethanol, and burned with the reat of the fuel, keeping the system dry.
