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 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 just inexpensive but you'll be recycling a bothersome waste product. Most importantly is the GREAT sensation of flexibility, self-reliance and empowerment it will offer you. Here's how to do it-- whatever you require to understand.

Straight grease fuel (SVO) systems can be a clean, effective and affordable choice. Unlike biodiesel, with SVO you need to customize the engine. The finest method is to fit an expert singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, along with fuel heating.

With the German Elsbett single-tank SVO system for example you can use petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and change off, like any other vehicle. 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 start the engine on normal petroleum diesel or biodiesel in one tank and then switch 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 benefits over SVO: it works in any diesel, without any conversion or adjustments to the engine or the fuel system-- simply put it in and go. It also has better cold-weather homes than SVO (but not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by many 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 speculative and require additional development.

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 needs to be processed initially.

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

Anyway you have to process SVO too, especially WVO (waste grease, utilized, cooked), which lots of people with SVO systems utilize because it's inexpensive or complimentary for the taking. With WVO food particles and impurities and water must be removed, and it most likely needs to be deacidified too. Biodieselers state, "If I'm going to have 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.
