Jim- Bio-diesel is also known as soy-diesel around here. It is a spl. refined version of soy bean oil and can be run 100%, or any desired mixture with regular diesel fuel, in common diesel engines and without any modifications.
If you're having trouble with an ethanol blend my bet is that you're not really getting ethanol, but methanol instead. The fuel companies are notorious over the years for b.s.ing about using farm grown ethanol while quietly using their own petro based methanol.
Ethanol is benign in automotive fuel systems. First tank or two will probably pull up some moisture in the system and burn it off, but after that no more frozen gas lines and fuel filters!
Methanol is very chemically reactive and breaks down plastic and rubber fuel system parts. It also "eats" the insulation out them high dollar fuel pumps that are submerged in the fuel tank.
Go down to the package store and you'll get a bottle of 50% ethanol in a plastic bottle. Go over to the hardware store and you'll get methanol in either glass or spl coated metal containers. Go figger...
Also, both methanol and ethanol blending runs up the anti-knock rating of the fuel. That's OK, but the problem is that the fuel blenders get away with using a lower grade of gasoline to do the blending with. Like the old saying around here, "The fuel companies get the elevator and the farmers get the shaft!"
Anybody that has problems with ethanol blend gasoline should raise all kinds of he11 with your fuel supplier! Demand a material safety data sheet on the product and watch 'em squirm...
As to that '93 Buick... Just a WAG, but a new exhaust gas oxygen sensor might work miracles for 'ya. That gadget gives vital information to the fuel computer so the electronic fuel injection system creates the proper fuel/air mixture ratio for the engine.
Good luck, IHank
