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 business offer you. Your diesel motor will run much 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 only low-cost but you'll be recycling a frustrating waste product. Most importantly is the GREAT sensation of freedom, self-reliance and empowerment it will give you. Here's how to do it-- everything you require to understand.

Straight grease fuel (SVO) systems can be a tidy, reliable and affordable choice. Unlike biodiesel, with SVO you need to modify the engine. The finest method is to fit a professional 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 example 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 have to begin the engine on common petroleum diesel or biodiesel in one tank and after that 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. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, without any conversion or modifications to the engine or the fuel system-- just put it in and go. It likewise has better cold-weather residential or commercial properties than SVO (however not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

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

On the other hand, biodiesel can be more expensive, depending just 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 large and rapidly growing worldwide band of homebrewers do not mind-- they make a supply every week or when a month and soon get utilized to it. Many have actually been doing it for several years.

Anyway you need to process SVO too, particularly WVO (waste grease, used, cooked), which many individuals with SVO systems utilize since it's inexpensive or free for the taking. With WVO food particles and pollutants and water must be removed, and it most likely needs to be deacidified too. Biodieselers state, "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 state. To each his own.
