Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the big oil business offer you. Your diesel motor will run 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 only inexpensive however you'll be recycling a problematic waste item. Best of all is the GREAT feeling of freedom, self-reliance and empowerment it will provide you. Here's how to do it-- everything you require to understand.

Straight veggie oil fuel (SVO) systems can be a clean, efficient and cost-effective option. Unlike biodiesel, with SVO you need to modify the engine. The best way is to fit an expert 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 begin up and go, stop and turn off, like any other automobile. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are likewise two-tank SVO systems which the oil to make it thinner. You need to start the engine on regular petroleum diesel or biodiesel in one tank and then 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 information on straight veggie 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-- just put it in and go. It also has much better cold-weather properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to state that many SVO systems are still speculative and need further advancement.

On the other hand, biodiesel can be more pricey, depending how much you make, what you make it from and whether you're comparing it with new oil or utilized oil (and depending on where you live). And unlike SVO, it has actually to be processed first.

But the large and rapidly growing around the world band of homebrewers do not mind-- they make a supply weekly or as soon as a month and soon get used to it. Many have actually been doing it for many years.

Anyway you have to process SVO too, specifically WVO (waste grease, 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 most likely must be deacidified too. Biodieselers state, "If I'm going to have to do all that I might also make biodiesel instead." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
