Will a 1991 dodge Dakota run on E-85 fuel?
No, a 1991 Dodge Dakota was not designed to run on E85 fuel. E85 requires specific fuel system components (fuel lines, seals, etc.) that are resistant to the corrosive properties of ethanol. A 1991 vehicle almost certainly does not have these components. Running E85 in a vehicle not designed for it will likely cause significant damage.
