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 companies sell you. Your will run much 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 utilized cooking oil it's not just low-cost however you'll be recycling a bothersome waste item. Most importantly is the GREAT sensation of flexibility, independence and empowerment it will provide you. Here's how to do it-- everything you need to understand.

Straight veggie oil fuel (SVO) systems can be a clean, effective and economical choice. Unlike biodiesel, with SVO you need to modify the engine. The finest way is to fit a professional singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for example you can use petro-diesel, biodiesel or SVO, in any combination. Just begin up and go, stop and switch off, like any other vehicle. 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 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 benefits 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 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 many nations, including countless miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that lots of SVO systems are still speculative and require further development.

On the other hand, biodiesel can be more pricey, 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 upon where you live). And unlike SVO, it has actually to be processed initially.

But the large and rapidly growing around the world band of homebrewers don't mind-- they make a supply every week or as soon as a month and soon get utilized to it. Many have been doing it for many years.

Anyway you need to process SVO too, especially WVO (waste veggie oil, utilized, cooked), which many individuals with SVO systems use because it's cheap or free for the taking. With WVO food particles and pollutants and water need to be eliminated, and it probably needs to be deacidified too. Biodieselers say, "If I'm going to have to do all that I may as well make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
