Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the big oil companies sell you. Your diesel motor will run better and last longer on your home-made fuel, and it's much cleaner-- much better for the environment and much better for health.

If you make it from utilized cooking oil it's not just inexpensive but you'll be recycling a troublesome waste product. Most importantly is the GREAT feeling of flexibility, self-reliance and empowerment it will provide you. Here's how to do it-- everything you require to know.

Straight veggie oil fuel (SVO) systems can be a tidy, reliable and economical option. Unlike biodiesel, with SVO you have to modify the engine. The best way is to fit an expert singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, along with fuel heating.

With the German Elsbett single-tank SVO system for instance you can utilize petro-diesel, biodiesel or SVO, in any combination. Just start up and go, stop and switch off, like any other car. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are likewise two-tank SVO systems which pre-heat the oil to make it thinner. You need to start the engine on common petroleum diesel or biodiesel in one tank and then change to SVO in the other tank when the veg-oil is hot enough, and change back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More details on straight veggie oil systems in my blog site.

3. Biodiesel or SVO?

Biodiesel has some clear benefits over SVO: it operates in any diesel, with no conversion or modifications to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather properties than SVO (however not as good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by many long-lasting tests in lots of nations, including of miles on the road.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to state that lots of SVO systems are still speculative and need further development.

On the other hand, biodiesel can be more costly, depending how much you make, what you make it from and whether you're comparing it with brand-new oil or used oil (and depending upon where you live). And unlike SVO, it has to be processed first.

But the large and quickly growing around the world band of homebrewers do not mind-- they make a supply every week or once a month and soon get used to it. Many have been doing it for several years.

Anyway you need to process SVO too, specifically WVO (waste veggie oil, used, cooked), which lots of people with SVO systems use due to the fact that it's cheap or complimentary for the taking. With WVO food particles and pollutants and water should be removed, and it most likely should be deacidified too. Biodieselers say, "If I'm going to need to do all that I may too make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
