Anybody can make biodiesel. It's simple, you can make it in your kitchen-- 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 better for health.

If you make it from utilized cooking oil it's not only inexpensive but you'll be recycling a troublesome waste item. Best of all is the GREAT feeling of flexibility, independence and empowerment it will give you. Here's how to do it-- whatever you need to understand.

Straight grease fuel (SVO) systems can be a tidy, effective and economical choice. Unlike biodiesel, with SVO you need to customize the engine. The finest method 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 mix. Just launch and go, stop and turn off, like any other automobile. 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 need to begin the engine on normal petroleum diesel or biodiesel in one tank and after that switch to SVO in the other tank when the 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, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has much better cold-weather properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by many long-lasting tests in many countries, including 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 experimental and require further development.

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 upon where you live). And unlike SVO, it has actually to be processed first.

But the big and quickly growing around the world band of homebrewers do not 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 need to process SVO too, specifically WVO (waste veggie oil, utilized, prepared), which many individuals with SVO systems use because it's low-cost or totally free for the taking. With WVO food particles and impurities and water should be gotten rid of, and it probably ought to be deacidified too. Biodieselers say, "If I'm going to need to do all that I may as well make biodiesel rather." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
