1 Make your own Biodiesel Part 2

Anybody can make biodiesel. It's simple, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the huge 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 better for health.

If you make it from utilized cooking oil it's not only low-cost but you'll be recycling a troublesome waste product. Best of all is the GREAT feeling of flexibility, self-reliance and empowerment it will provide you. Here's how to do it-- everything you need to understand.

Straight grease fuel (SVO) systems can be a clean, effective and affordable choice. Unlike biodiesel, with SVO you have to modify the engine. The very best way is to fit an expert singletank SVO system with replacement injectors and glowplugs for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for circumstances you can utilize petro-diesel, biodiesel or SVO, in any mix. Just launch and go, stop and switch off, like any other vehicle. 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 have to start the engine on ordinary petroleum diesel or biodiesel in one tank and after that switch to SVO in the other tank when the veg-oil is hot enough, and change back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More details on straight grease systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear benefits over SVO: it works in any diesel, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It also has better cold-weather residential or commercial properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in lots of nations, including millions of miles on the road.

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

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

But the large and rapidly growing around the world band of homebrewers don't mind-- they make a supply weekly or once a month and quickly get utilized to it. Many have been doing it for several years.

Anyway you need to process SVO too, particularly WVO (waste veggie oil, used, cooked), which lots of people with SVO systems utilize since it's low-cost or free for the taking. With WVO food particles and impurities and water need to be removed, and it most likely should be deacidified too. Biodieselers state, "If I'm going to have to do all that I may as well make biodiesel rather." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
