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 huge 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 better for health.

If you make it from used cooking oil it's not just cheap however you'll be recycling a problematic waste item. Most importantly is the GREAT feeling of liberty, self-reliance and empowerment it will offer you. Here's how to do it-- everything you need to understand.

Straight vegetable oil fuel (SVO) systems can be a tidy, efficient and cost-effective alternative. 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 instance you can utilize petro-diesel, biodiesel or SVO, in any combination. Just begin 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 also two-tank SVO systems which pre-heat the oil to make it thinner. You need to start the engine on common 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, 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 good as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by numerous long-term tests in lots of 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 numerous SVO systems are still experimental and need further advancement.

On the other hand, biodiesel can be more expensive, 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 needs to be processed initially.

But the large and rapidly growing band of homebrewers do not mind-- they make a supply every week or as soon as a month and soon get utilized to it. Many have been doing it for years.

Anyway you have to process SVO too, especially WVO (waste grease, utilized, cooked), which lots of people with SVO systems utilize because it's cheap or free for the taking. With WVO food particles and pollutants and water should be removed, and it probably needs to be deacidified too. Biodieselers say, "If I'm going to have to do all that I might too make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
