Anybody can make biodiesel. It's easy, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the huge oil companies sell 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 better for health.

If you make it from used cooking oil it's not just low-cost however you'll be recycling a frustrating waste product. Best of all is the GREAT sensation of liberty, self-reliance and empowerment it will give you. Here's how to do it-- whatever you need to know.

Straight grease fuel (SVO) systems can be a tidy, effective and cost-effective alternative. Unlike biodiesel, with SVO you need to customize the engine. The very best 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 utilize petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and change 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 need to start the engine on common petroleum diesel or biodiesel in one tank and then 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.

More information on straight grease systems in my blog.

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-- just put it in and go. It also has better cold-weather properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by many long-term tests in many nations, including millions of 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 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 upon where you live). And unlike SVO, it has actually to be processed initially.

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

Anyway you need to too, especially WVO (waste grease, used, prepared), which many individuals with SVO systems utilize because it's inexpensive or free for the taking. With WVO food particles and pollutants and water need to be gotten rid of, and it most likely ought to 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 say. To each his own.
