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 better and last longer on your home-made fuel, and it's much cleaner-- much better for the environment and better for health.

If you make it from used cooking oil it's not only low-cost however you'll be recycling a bothersome waste item. Most importantly is the GREAT feeling of liberty, independence and empowerment it will provide you. Here's how to do it-- everything you require to know.

Straight grease fuel (SVO) systems can be a tidy, efficient and cost-effective choice. Unlike biodiesel, with SVO you have to customize the engine. The best way 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 mix. Just start up and go, stop and change off, like any other car. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are likewise two-tank SVO systems which the oil to make it thinner. You need 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 switch back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More information on straight grease systems in my blog.

3. Biodiesel or SVO?

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

it's backed by many long-lasting tests in many countries, including countless miles on the road.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to state that numerous SVO systems are still speculative and need additional development.

On the other hand, biodiesel can be more pricey, 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 on where you live). And unlike SVO, it has actually to be processed initially.

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

Anyway you have to process SVO too, particularly WVO (waste grease, utilized, prepared), which lots of people with SVO systems use since it's low-cost or free for the taking. With WVO food particles and impurities and water should be gotten rid of, and it most likely should be deacidified too. Biodieselers say, "If I'm going to have to do all that I might as well make biodiesel rather." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
