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

If you make it from used cooking oil it's not just inexpensive but you'll be recycling a troublesome waste item. Best of all is the GREAT sensation of liberty, independence and empowerment it will offer you. Here's how to do it-- everything you require to know.

Straight grease fuel (SVO) systems can be a clean, reliable and cost-effective option. Unlike biodiesel, with SVO you need to customize the engine. The very best way is to fit an expert 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 instance you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn off, like any other automobile. Journey to Forever's Toyota TownAce van utilizes 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 start the engine on normal 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 details 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 modifications to the engine or the fuel system-- just put it in and go. It likewise 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 lots of long-lasting tests in many nations, countless miles on the road.

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

On the other hand, biodiesel can be more costly, depending 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 actually to be processed first.

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

Anyway you need to process SVO too, specifically WVO (waste grease, utilized, cooked), which numerous people with SVO systems use due to the fact that it's inexpensive or complimentary for the taking. With WVO food particles and impurities and water must be gotten rid of, and it most likely ought to be deacidified too. Biodieselers say, "If I'm going to need 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.
