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 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-- much better for the environment and much better for health.

If you make it from utilized cooking oil it's not just inexpensive but you'll be recycling a bothersome waste product. Best of all is the GREAT sensation of freedom, self-reliance and empowerment it will provide you. Here's how to do it-- whatever you need to understand.

Straight vegetable oil fuel (SVO) systems can be a clean, reliable and cost-effective alternative. Unlike biodiesel, with SVO you have to customize the engine. The finest way 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 circumstances you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn off, like any other cars and truck. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are also two-tank SVO systems which pre-heat the oil to make it thinner. You have to begin the engine on regular 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 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 likewise has much better cold-weather residential or commercial properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by lots of long-lasting tests in lots of nations, consisting of millions of miles on the road.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to state that lots of SVO systems are still experimental and require further advancement.

On the other hand, biodiesel can be more expensive, 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 on where you live). And unlike SVO, it needs to be processed first.

But the big and rapidly growing worldwide band of homebrewers do not mind-- they make a supply each week or once a month and quickly get used to it. Many have actually been doing it for several years.

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