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 much better for health.


If you make it from used cooking oil it's not just cheap but you'll be recycling a bothersome waste product. Best of all is the GREAT feeling of freedom, self-reliance and empowerment it will give you. Here's how to do it-- everything you need to know.


Straight vegetable oil fuel (SVO) systems can be a clean, effective and cost-effective option. Unlike biodiesel, with SVO you have to customize the engine. The finest way is to fit a professional 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 utilize petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn 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 need to begin the engine on ordinary petroleum diesel or biodiesel in one tank and then 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.

3. Biodiesel or SVO?


Biodiesel has some clear advantages over SVO: it works in any diesel, with no 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 (however not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,


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


Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to state that lots of SVO systems are still speculative and require more development.


On the other hand, biodiesel can be more costly, depending how much you make, what you make it from and whether you're comparing it with brand-new oil or used oil (and depending upon where you live). And unlike SVO, it has to be processed first.


But the large and quickly growing worldwide band of homebrewers don't mind-- they make a or when a month and quickly get used to it. Many have been doing it for several years.


Anyway you need to process SVO too, specifically WVO (waste vegetable oil, used, cooked), which lots of people with SVO systems use since it's inexpensive or complimentary for the taking. With WVO food particles and pollutants and water need to be eliminated, and it probably needs to be deacidified too. Biodieselers state, "If I'm going to need to do all that I might as well make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
