Anybody can make biodiesel. It's simple, you can make it in your cooking area-- 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 better for health.

If you make it from utilized cooking oil it's not just low-cost but you'll be recycling a frustrating waste product. Best of all is the GREAT feeling of freedom, independence and empowerment it will provide you. Here's how to do it-- everything you need to know.

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

With the German Elsbett single-tank SVO system for instance you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn off, like any other cars and truck. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are also two-tank SVO systems which pre-heat the oil to make it thinner. You need to begin the engine on ordinary petroleum diesel or biodiesel in one tank and after that 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.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it works in any diesel, without any conversion or adjustments to the engine or the fuel system-- just put it in and go. It also has better cold-weather homes than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to say that lots of SVO systems are still experimental and need additional advancement.

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

But the large and rapidly growing worldwide band of homebrewers don't mind-- they make a supply every week or when a month and quickly get used to it. Many have been doing it for many years.

Anyway you have to process SVO too, particularly WVO (waste grease, used, cooked), which many individuals with SVO systems utilize since it's inexpensive or totally free for the taking. With WVO food particles and pollutants and water should be gotten rid of, and it probably must be deacidified too. Biodieselers say, "If I'm going to need to do all that I might also make biodiesel instead." But SVO types scoff at that-- it's much less than making biodiesel, they state. To each his own.
