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 companies sell you. Your diesel motor will run much 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 utilized cooking oil it's not only cheap but you'll be recycling a problematic waste product. Best of all is the GREAT feeling of freedom, independence and empowerment it will offer you. Here's how to do it-- whatever you require to know.

Straight grease fuel (SVO) systems can be a clean, efficient and cost-effective choice. Unlike biodiesel, with SVO you have 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 instance you can utilize petro-diesel, biodiesel or SVO, in any mix. Just launch 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 pre-heat the oil to make it thinner. You have to start the engine on regular 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 advantages over SVO: it operates in any diesel, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather residential or commercial properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

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

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

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

Anyway you have to process SVO too, especially WVO (waste vegetable oil, utilized, prepared), which lots of people with SVO systems utilize since it's inexpensive or totally free for the taking. With WVO food particles and pollutants and water should be gotten rid of, and it most likely ought to be deacidified too. Biodieselers say, "If I'm going to need to do all that I may as well make biodiesel instead." But SVO types belittle that-- it's much less processing than making biodiesel, they state. To each his own.
