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 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 inexpensive but you'll be recycling a frustrating waste item. Best of all is the GREAT sensation of flexibility, self-reliance and empowerment it will offer you. Here's how to do it-- whatever you need to understand.

Straight vegetable oil fuel (SVO) systems can be a clean, reliable and cost-effective option. Unlike biodiesel, with SVO you have to modify the engine. The best 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 circumstances you can utilize petro-diesel, biodiesel or SVO, in any mix. Just start up and go, stop and change 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 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 veggie oil systems in my blog site.

3. Biodiesel or SVO?

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

it's backed by lots of long-term tests in many nations, consisting of countless miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that many SVO systems are still experimental and require additional 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 brand-new oil or utilized oil (and depending on where you live). And unlike SVO, it needs to be processed first.

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

Anyway you have to process SVO too, particularly WVO (waste vegetable oil, used, cooked), which many individuals with SVO systems use because it's low-cost or complimentary for the taking. With WVO food particles and impurities and water must be gotten rid of, and it probably needs to be deacidified too. Biodieselers state, "If I'm going to need to do all that I may too make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
