Anybody can make biodiesel. It's simple, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the big oil companies sell you. Your diesel motor will run 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 utilized cooking oil it's not just inexpensive but you'll be recycling a frustrating waste product. Most importantly is the GREAT feeling of liberty, independence and empowerment it will give you. Here's how to do it-- everything you need to know.

Straight grease fuel (SVO) systems can be a clean, reliable and affordable alternative. Unlike biodiesel, with SVO you need to modify the engine. The very best way 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 launch and go, stop and switch off, like any other automobile. 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 begin the engine on ordinary 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 switch back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More details on straight grease 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-- simply put it in and go. It likewise has better cold-weather properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-lasting tests in many nations, consisting of millions of miles on the roadway.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's reasonable to say that numerous SVO systems are still speculative and need 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 needs to be processed first.

But the big and quickly growing worldwide band of homebrewers don't mind-- they make a supply every week or as soon as a month and quickly get used to it. Many have actually been doing it for years.

Anyway you have to process SVO too, specifically WVO (waste veggie oil, utilized, cooked), which many individuals with SVO systems use due to the fact that it's inexpensive or totally free for the taking. With WVO food particles and impurities and water should be gotten rid of, and it probably needs to be deacidified too. Biodieselers say, "If I'm going to need to do all that I might too make biodiesel rather." But scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
