mguar, who are you? i haven't seen you post in any other threads and it seems that any time the ethanol topic comes up someone pops in out of nowhere to defend E10 with poor logic.
like has been said, while ethanol blended fuel has been around for a long time, it has only recently become required. your example of how ethanol reduces crude oil use is flawed, because it has been shown that the amount of crude oil replaced by ethanol is outweighed by the amount of diesel used in the growing process. you can say the amish don't use diesel, but they don't produce the majority of the corn so its rediculous to bring it up.
it is also widely known that ethanol will eat anything not nylon or stainless in the fuel system, and even cars that are "approved" for e10 fuel have had issues that can be traced back to E10 fuel.
i also noticed that a lot of people seem to be confusing the corn ethanol subsidy and price protection being eliminated with the end of mandated ethanol blending. they are two separate things. what this will do is allow the sugar cane and switchgrass based ethanol from south america to more easily compete with US-grown corn-based ethanol.
Widely known.......interesting..
So if I say that all right handed people are widely known to be poor drivers that makes it true? .
Please provide some documentation as to your claim that more diesel is used creating ethanol that ethanol produced..
Brazil manages to make far more fuel than it every imports in oil.. Why can they and we Americans can't?
Which farms? How fertile are the fields, what sort of yield are we discussing? What sort of equipment is used? How far are the fields from the ethanol plant? What sort of fuel; mileage do the delivery trucks make? How is the ethanol delivered to the refinery? Train, Pipeline? Truck?
What sort of planting practices are used til, no-til?
How many of those farmers use used cooking oil to either farm or haul their delivery to the plant?
as for your first real question, there's this NYT article talking about which fuels actually reduce greenhouse gas emissions, which discusses how silly the corn subsidy and cane-based ethanol tax was:
http://wheels.blogs.nytimes.com/2007/09/24/corn-ethanol-biofuel-or-biofraud/
and then there is this article, which discusses the economic cost of corn-based ethanol: http://www.greentechmedia.com/articles/read/the-true-cost-of-corn-ethanol/
and also this article which talks about the energy costs, as well as the indirect land use changes and also touches on increased food costs due to biofuel production: http://www.greentechmedia.com/articles/read/an-inconvenient-truth-biofuels-have-a-...
in order to grow corn, farmers have to run tractors, which usually run on diesel, then they run harvesters, also on diesel, then it is transported at least some distance by truck and then possibly by train which both will run on diesel. then there is the energy required to actually make the ethanol, which uses electricity produced by usually either coal or natural gas, which will produce emissions that must also be counted. then there is the fact that depending on the car, there will be a reduction in mileage due to the addition of the lower energy density ethanol to the fuel.
as to the rest of your questions, obviously it will depend, but i seriously doubt that anyone who's living is dependent on a piece of equipment working reliably is going to run WVO in that equipment. you can just look to the people on this board that have had issues with fuel quality, gelling, mechanical part wear and other issues to see that its a bit more complicated than "just switch everything to X fuel"
