Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the huge oil companies offer 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 used cooking oil it's not just cheap but you'll be recycling a frustrating waste item. Best of all is the GREAT sensation of freedom, self-reliance and empowerment it will offer you. Here's how to do it-- everything you need to know.

Straight grease fuel (SVO) systems can be a tidy, efficient and cost-effective choice. Unlike biodiesel, with SVO you have to modify the engine. The best method 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 circumstances you can use petro-diesel, biodiesel or SVO, in any combination. Just start up and go, stop and switch off, like any other vehicle. Journey to Forever's Toyota TownAce van utilizes 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 ordinary petroleum diesel or biodiesel in one tank and then switch to SVO in the other tank when the veg-oil is hot enough, and switch back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

3. or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, with no conversion or adjustments to the engine or the fuel system-- just put it in and go. It also has better cold-weather properties than SVO (but not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in lots of 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 require 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 utilized oil (and depending on where you live). And unlike SVO, it needs to be processed initially.

But the big and rapidly growing worldwide band of homebrewers do not mind-- they make a supply every week or as soon as a month and soon get used to it. Many have actually been doing it for years.

Anyway you have to process SVO too, particularly WVO (waste vegetable oil, used, prepared), which many individuals with SVO systems use because it's low-cost or totally free for the taking. With WVO food particles and impurities and water must be gotten rid of, and it most likely needs to be deacidified too. Biodieselers say, "If I'm going to have to do all that I might as well make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
