Some cars are listed as "TDIs", meaning they have a Turbo-Charge
Direct Injection Engine — these cars can also be run on Biodiesel.

Diesel engines are fuel-efficient, for example VW
Jetta TDIs get around 47 mpg. Earlier diesel cars, produced in the
1960s and 1970s were noisy and produced noxious emissions. However, new
models are much less noisy, and when run on biodiesel, produce less toxic emission that regular, gasoline-powered cars.

Diesel vehicles currently available in the U.S. are:

Cars

• Volkswagen Golf, Jetta, Jetta Wagon, New Beetle, Passat (2004)
• Mercedes
  E-320 Sedan (2004)

SUVs

• Chrysler Jeep Liberty (2004)
• Volkswagen Touareg SUV (2004) [Note: fuel
  economy not the best though]

Trucks

• Chevy Silverado
• GMC Sierra
• Dodge Ram
• Ford E-series, F-series

Here is a list of Used diesel car models.
A very detailed
list of models is also available.

What are the benefits of using Biodiesel?

• No Engine Conversions. Biodiesel runs in
  any conventional, unmodified diesel engine. No engine modifications are
  necessary to use biodiesel and there is no �engine conversion.� In other
  words, �you just pour it into the fuel tank.�
• Lubricates Engines. Biodiesel is more lubricating
  than diesel fuel, it increases the engine life and it can be used to
  replace sulfur, a lubricating agent that, when burned, produces sulfur
  dioxide – the primary component in acid rain. Instead of sulfur, all
  diesel fuel sold in France contains 5% biodiesel.
• Less Emissions. Biodiesel is nearly carbon-neutral,
  meaning it contributes almost zero emissions to global warming. Since
  biodiesel comes from plants and plants breathe carbon dioxide, there
  is no net gain in carbon dioxide from using biodiesel. Biodiesel also
  dramatically reduces other emissions fairly dramatically. Plus, the exhaust
  smells like popcorn or french fries.
• Non-Toxic. Biodiesel is safe to handle because
  it is biodegradable and non-toxic. According to the National Biodiesel
  Board, �neat biodiesel is as biodegradable as sugar and less toxic than
  salt.�
• Blends with Petroleum Diesel. Biodiesel
  can be used alone or mixed in any amount with petroleum diesel fuel.
  A 20% blend of biodiesel with diesel fuel is called �B20,� a 5% blend
  is called �B5� and so on.
• Safe to Transport. The flash point of a fuel
  is defined as the temperature at which it will ignite when exposed to
  a spark or flame. Biodiesel’s flash point is over 300° Fahrenheit,
  well above petroleum based diesel fuel’s flash point of around
  125° Fahrenheit. Testing has shown the flash point of biodiesel blends
  increases as the percentage of biodiesel increases. Therefore, biodiesel
  and blends of biodiesel with petroleum diesel are safer to store, handle,
  and use than conventional diesel fuel.
• Good for national security. Since it’s
  made domestically, it reduces dependence on foreign oil.
• Good for national economy. Using biodiesel
  keeps fuel buying dollars within the country instead of sending it to
  foreign countries. This reduces our trade deficit and creates jobs.
• No Storage Conversions. Biodiesel can be
  stored anywhere that petroleum diesel fuel is stored. All diesel fueling
  infrastructure including pumps, tanks and transport trucks can use biodiesel
  without modifications.
• Good Performance. Engines running on biodiesel
  run normally and have similar fuel mileage to engines running on diesel
  fuel. Auto ignition, fuel consumption, power output, and engine torque
  are relatively unaffected by biodiesel.
• Drivability. We have yet to meet anyone
  who doesn’t notice an immediate smoothing of the engine with biodiesel.
  It just runs quieter, and produces less smoke.

What are the disadvantages of using Biodiesel?

• Limited availability. Biodiesel not readily
  available in much of the U.S. — yet. Here is a map of
  biodiesel pumping stations. However, consumption of biodiesel
  in the U.S. increases each year. Also, unlike other alternative fuels,
  you can fill up your car with petroleum diesel in a pinch.
• Cold Weather Gelling. Like diesel fuel, biodiesel
  can gel in cold weather. If you live in a very cold-winter climate, there
  are simple preventative measures you can take. In fact, some diesel vehicles
  come stock with cold weather equipment.
• NOx Emissions. The one emission that goes
  up slightly with biodiesel is NOx (up to 15%). NOx contributes to smog.
  Engine modifications can reduce NOx emissions.
• Biodiesel will clean your injectors and fuel lines. If
  you have an old diesel vehicle, there’s a chance that your first tank
  or two of biodiesel could free up all the accumulated crud and clog your
  fuel filter.
• Degrades rubber parts on older vehicles. Vehicles
  manufactured before he mid-1990s might require upgrades of fuel lines
  (a cheap, easy upgrade), as biodiesel can eat through certain types of
  rubber. Almost all new vehicles should have no problem with biodiesel.

How is fuel efficiency (mileage) affected by biodiesel?
The fuel efficiency is the same for a petroleum diesel.

How are speed and power affected by biodiesel?
In tests done in U.S. universities and those in Europe, engines running on
biodiesel have minor, if any differences in torque, horse power, range, and
top speed. The experience with biodiesel users is that engines running
on biodiesel generally idle smoother and accelerate more smoothly.

Can biodiesel be produced in mass quantities — i.e. enough to
completely replace gasoline?
Yes. Biodiesel can be made in vast quantities from other sources
such as fast-growing, naturally occurring strains of algae. In Germany,
there is enough biodiesel produced to offer the fuel at over 1,300 service
stations across the country.

When was biodiesel first used?
Transesterification was conducted as early as 1853. Rudolf Diesel
designed this engine to run on vegetable oil. He did a demonstration at the
1900 World’s Fair where he ran his engine on peanut oil. One of the first
uses of biodiesel (transesterified vegetable oil) was powering heavy vehicles
in South Africa before World War II.

Where can I buy biodiesel?
Here is a map
and list of pumping stations. You can also have it shipped
from various
companies. Or make if yourself (see below).

How much does biodiesel cost per gallon?
It depends where you live and the manufacturer — the cost
can range from $1.90-$3.50. For more details see the price
reports for alternative fuels.

What does it cost to make Biodiesel yourself?
If you make
biodiesel yourself, it costs about 60 cents per gallon to produce.
Most people use about 600 gallons of fuel a year (about 10 gallons a
week). Home-made biodiesel would then cost around $360 per year to produce
the 600 gallons (eleven 55 gallon drums of it). In comparison, gasoline
would cost $1122 per year at $1.87 per gallon.

Can I sell the biodiesel I make?
Generally, you are allowed to sell moderate quantities of biodiesel for "research purposes", for example 2000 gallons a year. If you want to sell biodiesel commercially in the U.S., you will
need permits and you will need to charge road tax (about $0.45/gal).

I make biodiesel (from vegetable oil) to run my car. Do I have
to pay excise tax? If so what form or how would I pay it?
From the IRS: The
applicable diesel fuel tax rate is 24.4 cents per gallon. This tax is paid
by submitting Form 720 Quarterly Federal Excise Tax Return.

Biodiesel is considered as a blended diesel
fuel. The person that produces the blended diesel fuel, outside the bulk transfer/terminal
system (blender), is liable for the tax which is imposed under IRC section
4081(b) upon sale or removal. Blended diesel fuel is any mixture of diesel
fuel, with respect to which tax has been imposed and any other liquid(such
as kerosene)which no tax has been imposed. The number of gallons of blended
diesel fuel subject to the tax, is the difference between the total number
of gallons of blended diesel fuel removed or sold, and the number of gallons
of previously taxed diesel fuel used to produce the blended diesel fuel. An
exclusion from tax on the “blended taxable fuel” mixture is provided in Treasury
Regulations section 48.4081-1(c)(1)(ii) for minor blending if: during any calendar
quarter the removal or sale of the mixture in aggregate by the blender is less
than 400 gallons. The IRS Form is 720 and publication 510.

What about running your car on straight vegetable oil (SVO)?
You must convert each vehicle you want to run on straight vegetable
oil (SVO). This includes an additional tank for the oil plus special pre-heaters
and control systems. These kits cost about $800 plus labor. While this fuel
need no conversion to produce (unlike biodiesel), the oil must be of very good
quality. Many SVO drivers prefer fresh vegetable oil (FVO) over Waste Vegetable
Oil (WVO) to minimize hassles from the variables in using a waste product.
When it comes time to sell this converted vehicle, your buyer may not be interested
in running it on SVO.

I have a diesel engine car and I use straight vegetable oil to power the car.
Is the vegetable oil considered fuel and do I have to pay any tax on the vegetable
oil?
If the vegetable oil(straight oil with no mixture) is bought at retail and
you put it in your vehicle for personal use, there is no excise tax. If this
vegetable oil is mixed with other types of fuel and you have less than 400
gallons in any calendar quarter, it will be exempted from blended taxable fuel.
Vegetable oil(straight oil) per se is not considered as motor fuel or special
fuel.

How do I convert my diesel car to run on raw vegetable oil?
Here the details on how to convert a diesel car to run on raw
vegetable oil. Here is a company that specializes in conversions.

Will I void my car’s warranty by using biodiesel?
Most
European diesel engines manufactured for the European market now come with
biodiesel-warranted engines. In Europe, Volkswagen, Mercedes, Volvo and
others are all warranted to run at 100% biodiesel. However, if you have
a diesel made for the U.S. market, you should check with the engine manufacturer
as to their warranty coverage. Some diesels in the US are now warranted
for use with biodiesel that meets the automobile manufacturer’s
fuel specifications. Most warranties state that any fuel system problem
caused by fuel that does not meet specs is not covered by the warranty,
however all vehicle-related problems are covered regardless of the type
of fuel used.

What adjustments should I make to my diesel engine before
using biodiesel?

1. Retard the injection timing by 2-3 degrees — this overcomes the effect
   of biodiesel’s higher cetane number. It also causes the fuel to burn
   cooler, thus reducing NOx emissions.
2. Petroleum diesel leaves a lot of dirt
   in the tank and the fuel system. Biodiesel is a good solvent — it
   tends to free the dirt and clean it out. Be sure to check the fuel filters
   regularly at first. Start off with a new fuel filter.
3. Check there are
   no natural rubber parts in the fuel system. If there are, replace them.
   Viton is best.

What are the details on protecting your car’s fuel lines in cold
weather?
Like diesel fuel, biodiesel can gel in cold weather. B100 (100%
biodiesel) gets slushy a little under 32°F. But B20 (20% biodiesel, 80%
regular diesel – more commonly available than B100) has a gel point of -15°F.

There are six different ways to keep a diesel vehicle’s fuel system
from gelling in winter. The use of a block heater at night and a tank heater
during the day has allowed biodiesel to be used in Yellowstone national
park down to -40 deg. F.

The six methods for keeping a diesel fuel system operational in winter
are:

1. An engine block heater to keep the engine warm at night. This helps
   with starting on cold mornings.
2. A fuel tank heater, which circulates coolant through a pipe in the
   fuel tank. Any good diesel shop can install one.
3. An electric element fuel line heater, which heats the fuel at one point.
4. A coolant-operated fuel heater, which uses hot coolant and a heat exchanger
   to heat a section of the fuel line.
5. An electric fuel line heater. This is like an electric blanket for
   the fuel line, which extends from the fuel tank to the fuel filter.
   Winterizing agents and additives.

What are the best vehicles to use with biodiesel?
Notes from the Veggie
Van FAQ: We recommend vehicles with in-line diesel engines as opposed
to vehicles with V-6, V-8, or opposed cylinder designs. If you can find
an vehicle with an in-line diesel and a turbocharger, that’s even better.
The small surface area of main bearings and short �throw� distance of
rods in non in-line diesel engines limit their ability to take advantage
of the diesel’s efficiency and power. In the US, we recommend Dodge trucks
with Cummins engines, Volkswagen vehicles with TDI engines, and the Mercedes
Sprinter van with Mercedes TDI engine (this is sold through Freightliner
http://www.freightliner.com). If you are buying a used vehicle, by far
the best value for the money is a Mercedes car or station wagon. (A used
Volkswagen TDI vehicle is also an excellent choice – but difficult to
find).
