Diesel engines are a wasted precious resource. They were orginally designed to run on any kind of organic oils, like peanut, canola, etc. Bio-Diesel is made from oil and alcohol, and the by product of making it is soap. the add alcohol to basically thin out the mixture and aid in combustion...but a Diesel engine can run on just straigh oil too, but the problem with that is the oil need to be heated in order for it to not clog up injectors...plus the engine has to be started with regular diesel then switched to heated plant oils after its running

the reason we use Diesel Fuel instead of natural oils is because its cheaper...Bio-Diesel cost roughly 4-5 dollars a gallon. to make. Even if you go into a supermarket, canola oil would come out to like 3-4 dollars a gallon.

What some diesel fanatics do is get the extra oil from fast food restaurants and use that for fuel, since the restaurant is usually willing to sell off the waste oil for free...imagine the exhaust of your car smelling like chicken nuggets.

Anyway, BioDiesel is much cleaner then you think, if you do the big picture senerio. If planted oil producing crops on all the unused farmland in america we'd be making fuel, oxygen. Burning the fuel from plants would net less hydrocarbons then using fossil fuels.

Why the hell do we not use diesel?????
