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 companies offer you. Your diesel motor will run 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 only inexpensive however you'll be recycling a problematic waste product. Best of all is the GREAT sensation of flexibility, independence and empowerment it will give you. Here's how to do it-- whatever you require to understand.

Straight vegetable oil fuel (SVO) systems can be a tidy, reliable and affordable option. Unlike biodiesel, with SVO you need to modify the engine. The very best way is to fit a professional 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 example you can utilize petro-diesel, biodiesel or SVO, in any . Just begin up and go, stop and change off, like any other cars and truck. 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 need to start the engine on regular petroleum 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.

More information on straight veggie 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-- just put it in and go. It likewise has much better cold-weather 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, including millions of miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that many SVO systems are still experimental and require more 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 used oil (and depending on where you live). And unlike SVO, it has to be processed first.

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

Anyway you have to process SVO too, specifically WVO (waste vegetable oil, utilized, cooked), which lots of people with SVO systems utilize due to the fact that it's low-cost or free for the taking. With WVO food particles and impurities and water need to be eliminated, and it most likely ought to be deacidified too. Biodieselers state, "If I'm going to have to do all that I might too make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
