My wife started using E85 fuel her gas mileage went from 22mpg to 17mpg. Even though there was a subsidy on the fuel she ended up having to purchase more. She has since switched back to regular fuel.

- stephen_g 13y agoYeah, I did a project on this sort of thing in Uni with E10. We found that the few cents less it costs per litre at the pump was not enough to pay for the extra fuel you had to buy to make up for the fact that there is less energy in the fuel (this is in Australia - pretty sure that we have subsidies here too). It was a few years ago, but I remember looking at research saying something like it not being really sustaiable (despite being renewable) because it requires too much energy to produce it for what you get out of it.
