Anybody can make biodiesel. It's easy, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the big 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 better for health.

If you make it from used cooking oil it's not just inexpensive but you'll be recycling a problematic waste item. Most importantly is the GREAT feeling of liberty, independence 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 affordable option. Unlike biodiesel, with SVO you need to customize 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 instance you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn off, like any other vehicle. Journey to Forever's Toyota TownAce van utilizes an Elsbett single-tank system. More

There are also two-tank SVO systems which pre-heat the oil to make it thinner. You have 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 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, with no conversion or modifications to the engine or the fuel system-- simply put it in and go. It also has better cold-weather properties than SVO (however not as great as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by numerous long-lasting tests in numerous countries, including countless miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, fuel, whereas it's fair to state that numerous SVO systems are still speculative 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 used oil (and depending on where you live). And unlike SVO, it has to be processed initially.

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

Anyway you need to process SVO too, specifically WVO (waste veggie oil, used, prepared), which many individuals with SVO systems use because it's cheap or complimentary for the taking. With WVO food particles and pollutants and water must 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 too make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
