I've been reading a lot about E85 gasoline/ethanol mixture and also biodiesel. Just wondering if anyone is using it in their vehicle and what type of difference you can see. I know that in the midwest there are a bunch of ethanol plants popping up lately. I've heard that more and more gas stations around these communities are carying E85 too. I think that everyone knows that the new turbodiesels can perform very well with an engine life up to 300k.
