We're sorry, but this page requires a browser with at least basic support for Cascading Style Sheets (CSS).

Any relatively modern browser (Internet Explorer 5+, Mozilla Firefox, Netscape 6+) should work.  In the meantime, we have tried to design this site to "fail gracefully" so that, in theory, you can still at least read the content, even if it isn't pretty and as well-structured as we would like.

We apologize for any inconvenience, but if you are still using such an old browser, you are also likely at high risk for viruses and other destructive invasions of your computer.  You really should upgrade even if just for your own online safety and security.

Biodiesel, B2/B20, SVO, and WVO

Here, vegetable oil is used as a fuel for any type of internal combustion engine. There are a few variations on this theme. Virgin (unused) oil or filtered waste vegetable oil (WVO) can be used in a modified engine. A straightforward chemical reaction on the above will produce biodiesel, which can be used in a regular diesel engine just as you would use diesel fuel. Recycling WVO not only uses pre-existing resources, but also burns more cleanly than traditional dinofuel.

Development History

In the early days of vehicle development, biomass-based fuel was primarily used. However, as it was more expensive to produce at the time, diesel engines were modified to accept lower-viscosity fossil fuels, and it's stuck until recent times. Starting in the 1980's, biomass-based fuel was once again viewed as a viable alternative, and various groups started developing what we know, today, as biodiesel. Others have taken to modifying their engines to accept the straight vegetable oil, without the conversion to biodiesel. Biodiesel, however, has the advantage that it can be used in a regular diesel engine.
