Folks, please keep in mind that Mr. Rudolf Diesel,(the original inventor of the "diesel engine", in 1892 and introduced at the 1903 world's fair), fully intended the deisel engine to run on peanut oil/vegatable oil due to it's ultra-high lubrication qualities. But when Mr. Diesel died shortly after the introduction at the world's fair,(a person would just have to wonder about inventors dying shortly after introducing a very compeditave product to he world), his partners sold the diesel engine pattens to the current oil companies who promptly began research on duplicating the peanut oil-fuel using fosil fuels,(using their product and 'bread & butter' so to speak). ( http://inventors.about.com/library/inventors/bldiesel.htm )

Sadly, the oil companies did achieve their goal of using fosil fuels to run the diesel engine. But the engine ran much less effecient and with much more 'noise' than using the intended "Bio-fuels" that Mr. Diesel had designed his engine to run on. This is one of the main reasons that the diesel engine was always only a second choice to the gasoline engine in the U.S. and adding to the fact that the major oil companies that America owned the patten rights to this engine. The diesel engine was only really used in quantities in Europe(until these latter days).

IMHO, seeking to use 'Bio-Diesel' fuels is paramont to any/all Americans that are seeking to break away from the 'corporate grips' that they hold over our economy and our lives. The only other viable alternative fuel source for engines would be alcohol,(Denatured Alcohol- 99.9% pure alcohol), conversions for gasoline burning engines.

Excellent work on moving back to the 'Bio-fuels' for your vehicle. Keep going! ...And keep in mind that you will not be alone in this search and that there will be quite a market for vegatable oils as a 'National Fuel Source' as this begins to actually catch on.
