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 business 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 but you'll be recycling a problematic waste product. Most importantly is the GREAT feeling of liberty, independence and empowerment it will offer you. Here's how to do it-- everything you require to know.

Straight veggie oil fuel (SVO) systems can be a tidy, efficient and cost-effective option. Unlike biodiesel, with SVO you need to modify 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 single-tank SVO system for instance you can utilize petro-diesel, biodiesel or SVO, in any mix. Just start up and go, stop and switch off, like any other car. 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 start the engine on regular petroleum diesel or biodiesel in one tank and after that 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 details 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 much better cold-weather residential or commercial properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

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

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that many SVO systems are still experimental and require further development.

On the other hand, biodiesel can be more expensive, 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 to be processed first.

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

Anyway you have to process SVO too, particularly WVO (waste grease, utilized, cooked), which many people with SVO systems use due to the fact that it's inexpensive or complimentary for the taking. With WVO food particles and pollutants and water must be removed, 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 instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
