Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the big oil business 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 used cooking oil it's not only cheap but you'll be recycling a problematic waste product. Most importantly is the GREAT sensation of freedom, independence and empowerment it will offer you. Here's how to do it-- everything you require to understand.

Straight grease fuel (SVO) systems can be a tidy, reliable and economical option. Unlike biodiesel, with SVO you need to modify the engine. The very 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 utilize petro-diesel, biodiesel or SVO, in any combination. Just start up and go, stop and switch off, like any other automobile. 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 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.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, without any conversion or modifications to the engine or the fuel system-- just put it in and go. It also has much better cold-weather homes than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by many long-term tests in lots of nations, including countless miles on the roadway.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to state that numerous SVO systems are still experimental and need additional 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 used oil (and upon where you live). And unlike SVO, it has to be processed initially.

But the big and quickly growing worldwide band of homebrewers don't mind-- they make a supply each week or once a month and soon get utilized to it. Many have actually been doing it for several years.

Anyway you need to process SVO too, specifically WVO (waste veggie oil, utilized, prepared), which many individuals with SVO systems use since it's low-cost or totally 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 say, "If I'm going to have to do all that I might also make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
