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 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 however you'll be recycling a troublesome waste item. Most importantly is the GREAT feeling of flexibility, self-reliance and empowerment it will provide you. Here's how to do it-- whatever you require to understand.

Straight grease fuel (SVO) systems can be a tidy, effective and economical choice. Unlike biodiesel, with SVO you have to customize the engine. The finest method 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 instance you can utilize petro-diesel, biodiesel or SVO, in any combination. Just begin up and go, stop and change off, like any other automobile. Journey to Forever's Toyota TownAce van utilizes 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 begin the engine on diesel or biodiesel in one tank and after that change 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 operates in any diesel, with no conversion or modifications to the engine or the fuel system-- simply put it in and go. It also has much better cold-weather properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

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

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 brand-new oil or utilized oil (and depending upon where you live). And unlike SVO, it has actually to be processed first.

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

Anyway you have to process SVO too, especially WVO (waste veggie oil, used, cooked), which lots of people with SVO systems use because it's low-cost or complimentary for the taking. With WVO food particles and impurities and water should be removed, and it most likely ought to be deacidified too. Biodieselers state, "If I'm going to need to do all that I may also make biodiesel rather." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
