Anybody can make biodiesel. It's easy, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the big 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 just low-cost however you'll be recycling a problematic waste product. Most importantly is the GREAT sensation of freedom, self-reliance and empowerment it will provide you. Here's how to do it-- everything you need to understand.

Straight grease fuel (SVO) systems can be a tidy, reliable and economical choice. Unlike biodiesel, with SVO you need to customize the engine. The best 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 mix. Just start up and go, stop and turn off, like any other car. 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 benefits over SVO: it works in any diesel, without any conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather properties than SVO (however not as good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by many long-term tests in countries, consisting of countless miles on the road.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to say that numerous SVO systems are still speculative and require more 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 first.

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

Anyway you have to process SVO too, especially WVO (waste vegetable oil, utilized, prepared), which many individuals with SVO systems utilize since it's inexpensive or totally free for the taking. With WVO food particles and impurities and water need to be eliminated, and it probably should be deacidified too. Biodieselers say, "If I'm going to have to do all that I might too make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
