why not use biodeisel?

Answer 1

no stations around here have it. Plus, I don't own a diesel auto.

so there are two reasonable reasons. But back when gas was 90 cents a gal, i did use gasohol.

Answer 2

Because all the infra-structure already in place would have to be demolished and replaced. Bio-diesel is far more corrosive and reactive than regular diesel. New highly-reinforced tanks and pipelines would have to be installed, an investment of hundreds of millions of dollars.

Which is not a good enough reason to -not- convert. Bio-diesel is preferable in almost every way. And I have no problem asking people who have made the HIGHEST PROFIT in the HISTORY of CAPITALISM to shell out a litlle for facility upgrades.

Answer 3

Real diesel is bio diesel. Diesel engines were created so that farmers could use their cuttings as fuel to run their equipment. The trouble with mass bio diesel is water. Corn uses a lot of water to grow since it's mainly done through flood irrigation. It also causes the cost of corn to go up. You don't need just corn though.

Answer 4

What do you want to use it for? for trucks & trains it is not a bad option. for 'planes it is not powerful enough.

for personal transport, then electric vehicles are the best solution.
quiet, smell free, simple to make and maintain, better power/torque performance, regenerative brackeing... electric can be produced from a mix of fuels, including renewables, and delivered straight to the plug at your house or work.

Producing biodeisel by intensive agriculture can consume almost as much energy as it produces, agro-chemicals, agricultural machinery, shipping and processing - as well as having a big impact on the environment and having to choose between food or fuel security.

Answer 5

The world's biggest diesel fuel injector equipment (FIE) makers -- Bosch, Delphi (formerly Lucas), Denso, and Stanadyne -- just unveiled new "common position statements" warning of denials of warranty claims if fuels fail to meet certain quality standards.

One of the statements continues to warn against using over 5% biodiesel blends, in contradiction to the push for 20% blends ("B20") by the biodiesel lobby. Only engines specially designed for blends above 5%, or else 100% "neat" biodiesel, should use such fuels, the FIE makers say.

"Fuel injection equipment manufacturers cannot guarantee their products against performance or emissions failures if inappropriate fuels have been used," says the Joint FIE Manufacturers Statement on Fuels for Diesel Engines. "Any evidence that the product has fallen short of the required level of performance directly due to the use of non-acceptable fuels will render the manufacturers' guarantee null and void."

Biodiesel also has some performance disadvantages. The performance of biodiesel in cold conditions is markedly worse than that of petroleum diesel, and biodiesel made from yellow grease is worse than soybean biodiesel in this regard. At low temperatures, diesel fuel forms wax crystals, which can clog fuel lines and filters in a vehicle’s fuel system. The “cloud point” is the temperature at which a sample of the fuel starts to appear cloudy, indicating that wax crystals have begun to form. At even lower temperatures, diesel fuel becomes a gel that cannot be pumped. The “pour point” is the temperature below which the fuel will not flow. The cloud and pour points for biodiesel are higher than those for petroleum diesel.

Vehicles running on biodiesel blends may therefore exhibit more drivability problems at less severe winter temperatures than do vehicles running on petroleum diesel.11 This is a potential concern during the winter in much of the United States. The solvent property of biodiesel can cause other fuel-system problems. Biodiesel may be incompatible with the seals used in the fuel systems of older vehicles and machinery, necessitating the replacement of those parts if biodiesel blends are used.12 The initial use of B20 or B100 in any vehicle or machine requires care. Petroleum diesel forms deposits in vehicular fuel systems, and because biodiesel can loosen those deposits, they can migrate and clog fuel lines and filters.13

Another disadvantage of biodiesel is that it tends to reduce fuel economy. Energy efficiency is the percentage of the fuel’s thermal energy that is delivered as engine output, and biodiesel has shown no significant effect on the energy efficiency of any test engine. Volumetric efficiency, a measure that is more familiar to most vehicle users, usually is expressed as miles traveled per gallon of fuel (or kilometers per liter of fuel). The energy content per gallon of biodiesel is approximately 11 percent lower than that of petroleum diesel.14 Vehicles running on B20 are therefore expected to achieve 2.2 percent (20 percent x 11 percent) fewer miles per gallon of fuel.

Answer 6

for most people the reason is, that it is not readily available

why is it not readily available?

well, nobody want to produce it and make it readily available because they can't make money doing it

why can't they make money doing it?

because they have to compete with regular petroleum derived deisel and that can be produced cheaper than biodeisel

production costs are coming down for biodiesel and you can bet that the as soon as it is competitive with petroleum derived deisel there will be people out there bringing it to you so they can get rich

of course, if petroleum prices change (up or down) then the cost balance changes again

Answer 7

I think we should us Biodesial, but in reality, the cost of alternative fuels will drive down the cost of oil. Until they almost or do, drive the alternative fuel business out of the market place. This is a war, and they will use every trick available to them

Answer 8

I know one guy who uses it, his car exhaust really does smell like french fries (recycled fine filtered corn oil from food service)

Answer 9

Cause I'll run out of corn flakes

Answer 10

no reason not to, you just need to have a diesel and biodiesel is hard to find
