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 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 much better for health.

If you make it from used cooking oil it's not just cheap however you'll be recycling a problematic waste product. Most importantly is the GREAT feeling of flexibility, self-reliance and empowerment it will offer you. Here's how to do it-- whatever you require to understand.

Straight veggie oil fuel (SVO) systems can be a tidy, reliable and affordable choice. Unlike biodiesel, with SVO you have to modify the engine. The best way 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 example you can utilize petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and turn off, like any other cars and truck. Journey to Forever's Toyota TownAce van an Elsbett single-tank system. More

There are likewise two-tank SVO systems which pre-heat the oil to make it thinner. You have 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.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it works in any diesel, without any conversion or modifications to the engine or the fuel system-- just put it in and go. It also has better cold-weather residential or commercial properties than SVO (however not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by many long-term tests in many nations, consisting of millions of miles on the road.

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

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 brand-new oil or used oil (and depending on where you live). And unlike SVO, it has actually to be processed initially.

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

Anyway you have to process SVO too, especially WVO (waste grease, utilized, prepared), which lots of people with SVO systems use because it's cheap or free for the taking. With WVO food particles and pollutants and water must be gotten rid of, and it most likely must be deacidified too. Biodieselers say, "If I'm going to have to do all that I may as well make biodiesel instead." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
