Where E85 Ethanol is available (not very common), the price per gallon is often lower than regular unleaded gasoline. Though I've read that fuel economy is commonly reduced by 20% or more, when using E85 Ethanol.
I'm driving a flexible fuel vehicle; so it can run on either fuel, but I'm not sure if I can actually save money by switching to E85.
Is it possible to reduce fuel costs by switching to E85, or is it better to stick to good ol' gasoline?
