Many vegetable oils have similar fuel properties to diesel fuel, except for higher viscosity and lower oxidative stability. If these differences can be overcome, vegetable oil may substitute for #2 Diesel fuel, most significantly as engine fuel or home heating oil.For engines designed to burn #2 diesel fuel, the viscosity of vegetable oil must be lowered to allow for proper atomization of fuel, otherwise incomplete combustion and carbon build up will ultimately damage the engine. Many enthusiasts refer to vegetable oil used as fuel as waste vegetable oil (WVO) if it is oil that was discarded from a restaurant or straight vegetable oil (SVO) or pure plant oil (PPO) to distinguish it from biodiesel.

"The car now has two fuel tanks - one for diesel, which you need to start and warm up the car, and the other tank contains the used cooking oil. I installed a filter for the vegetable oil and two valves. One valve cuts the diesel fuel off and the other turns the oil on. The whole job took a day and a half."

KUANTAN, Malaysia — Rising prices for cooking oil are forcing residents of Asia’s largest slum, in Mumbai, India, to ration every drop. Bakeries in the United States are fretting over higher shortening costs. And here in Malaysia, brand-new factories built to convert vegetable oil into diesel sit idle,

I like the idea of Biodiesel because it means cheap, clean-burning fuel. Or in the case of FuelPod2, free, clean-burning fuel. The FuelPod2 takes any used cooking oil you may have, and converts it into usable Biodiesel...

I’ve come across several manuals and tutorials on the Internet showing you how to make bio diesel from cooking oil. I doubt I would ever attempt this unless I had this little home bio fuel processor. With FuelPod2 you can dump in your leftover cooking oils and fat and make 50 litres of bio diesel. Actually sounds good doesn’t it?

A story announcing the City of San Francisco's kick off of its SFGreasecycle program. A city run waste grease collection program to biodiesel for the cities 1500 diesel vehicles.While I highly commend the city for its mandate to use biodiesel, I am not so sure that taking over a business that they could have contracted out is the best idea.
