Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the huge oil business offer you. Your diesel motor will run better and last longer on your home-made fuel, and it's much cleaner-- 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 bothersome waste product. Best of all is the GREAT sensation of flexibility, independence and empowerment it will offer you. Here's how to do it-- whatever you require to know.

Straight vegetable oil fuel (SVO) systems can be a tidy, reliable and economical choice. Unlike biodiesel, with SVO you need to customize the engine. The very 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 combination. Just launch and go, stop and change off, like any other car. 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 start the engine on normal 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.

3. Biodiesel or SVO?

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

it's backed by lots of long-term tests in many nations, consisting of on the road.

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

On the other hand, biodiesel can be more costly, depending just how much you make, what you make it from and whether you're comparing it with 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 around the world band of homebrewers do not mind-- they make a supply weekly or as soon as a month and soon get used to it. Many have actually been doing it for years.

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