Re: What GM says about e85 conversions

Why would anyone want to convert a vehicle to run on E85 fuel and reduce their fuel mileage significantly?

GM is touting the number of new vehicles designed to run on E85 fuel, but the company does not talk about the reduced mileage.
Well I can see your stance may hold some truth to people that only use the cheapest gas (regular unleaded). Those of us who have to use Supreme, E85 is much more beneficial, cost-wise. Supreme is $3.25 here in vs E85 $2.69.
