Anybody can make biodiesel. It's easy, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the big oil companies sell you. Your diesel motor will run better and last longer on your home-made fuel, and it's much cleaner-- much better for the environment and much better for health.

If you make it from utilized cooking oil it's not only cheap but you'll be recycling a problematic waste product. Most importantly is the GREAT feeling of liberty, independence and empowerment it will provide you. Here's how to do it-- whatever you require to know.

Straight grease fuel (SVO) systems can be a tidy, efficient and . Unlike biodiesel, with SVO you need to modify the engine. The very best method 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 instance you can utilize petro-diesel, biodiesel or SVO, in any mix. Just launch and go, stop and turn off, like any other car. 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 have to start the engine on common 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 switch 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 advantages over SVO: it operates in any diesel, with no conversion or modifications 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 (however not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in many countries, consisting of countless miles on the road.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to say that numerous SVO systems are still experimental and require more 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 brand-new oil or utilized oil (and depending upon where you live). And unlike SVO, it needs to be processed initially.

But the large and rapidly growing around the world band of homebrewers don't mind-- they make a supply every week or when a month and soon get used to it. Many have been doing it for many years.

Anyway you need to process SVO too, especially WVO (waste vegetable oil, used, cooked), which lots of people with SVO systems utilize since it's low-cost or complimentary for the taking. With WVO food particles and impurities and water should 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 as well make biodiesel instead." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
