Bottom of the Mitten | Find a different dealership. They feed you a line about "adjusting the computer". There is no way to do that, unless maybe with an aftermarket tune but that won't happen at a dealership. Flex fuel vehicles have a way of determining the ethanol percentage via a fuel composition sensor or whatever, so there's no harm in running E85 whenever you want. Ethanol is a good cleaner so if you've been running crappy fuel its whole life its possible you could've dislodged some junk but it's unlikely since the fuel you normally use is 10% ethanol | |
