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 offer you. Your diesel motor 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 used cooking oil it's not just cheap however you'll be recycling a frustrating waste product. Most importantly is the GREAT sensation of liberty, self-reliance and empowerment it will provide you. Here's how to do it-- whatever you require to understand.

Straight grease fuel (SVO) systems can be a tidy, reliable and economical option. 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, as well as fuel heating.

With the German Elsbett single-tank SVO system for example you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and change 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 have to start the engine on normal 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.

More information on straight veggie oil systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it works in any diesel, with no conversion or adjustments to the engine or the fuel system-- just put it in and go. It likewise has better cold-weather properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a tidy, safe, ready-to-use, fuel, whereas it's fair to state that lots of SVO systems are still speculative and require more development.

On the other hand, biodiesel can be more pricey, 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 first.

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

Anyway you need to process SVO too, particularly WVO (waste veggie oil, used, prepared), which lots of people with SVO systems use due to the fact that it's cheap or free for the taking. With WVO food particles and impurities and water need to be eliminated, and it most likely needs to be deacidified too. Biodieselers state, "If I'm going to need to do all that I might also make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
