Anybody can make biodiesel. It's simple, you can make it in your cooking area-- and it's BETTER than the fuel the big oil business offer 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 used cooking oil it's not only cheap but you'll be recycling a bothersome waste item. Most importantly is the GREAT feeling of flexibility, self-reliance 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 customize the engine. The finest method is to fit an expert 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 circumstances you can utilize petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and turn off, like any other vehicle. 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 normal 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 benefits over SVO: it works in any diesel, without any conversion or adjustments to the engine or the fuel system-- just put it in and go. It likewise has better cold-weather properties than SVO (but not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-lasting tests in many countries, including millions of miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to say that many SVO systems are still experimental and need 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 new oil or utilized oil (and depending upon 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 weekly or once a month and quickly get used to it. Many have actually been doing it for several years.

Anyway you need to process SVO too, specifically WVO (waste vegetable oil, utilized, prepared), which many individuals with SVO systems use due to the fact that it's inexpensive or complimentary for the taking. With WVO food particles and impurities and water need to be removed, and it probably must be deacidified too. Biodieselers say, "If I'm going to have to do all that I may too make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
