Anybody can make biodiesel. It's easy, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the big oil business 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 low-cost however you'll be recycling a troublesome waste product. Best of all is the GREAT sensation of freedom, independence and empowerment it will offer you. Here's how to do it-- everything you require to understand.

Straight veggie oil fuel (SVO) systems can be a tidy, effective and economical option. 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, as well as 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 turn off, like any other car. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are likewise 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 vegetable oil systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, without any 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 great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in lots of countries, including countless miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that lots of SVO systems are still experimental and require further development.

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 needs to be processed first.

But the large and quickly growing around the world band of homebrewers do not mind-- they make a supply each week or as soon as a month and soon get utilized to it. Many have actually been doing it for several years.

Anyway you need to process SVO too, specifically WVO (waste grease, used, prepared), which many people with SVO systems use since it's cheap or complimentary for the taking. With particles and impurities and water must be gotten rid of, and it most likely should be deacidified too. Biodieselers state, "If I'm going to need to do all that I might also make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
