Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the big oil companies sell 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 just cheap however you'll be recycling a troublesome waste product. Most importantly is the GREAT sensation of flexibility, independence and empowerment it will give you. Here's how to do it-- whatever you need to know.

Straight vegetable oil fuel (SVO) systems can be a tidy, effective and cost-effective alternative. Unlike biodiesel, with SVO you need to customize the engine. The very best way is to fit a professional singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for example you can use petro-diesel, biodiesel or SVO, in any mix. Just launch and go, stop and turn off, like any other cars and truck. Journey to Forever's Toyota TownAce van utilizes 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 begin the engine on common petroleum diesel or in one tank and after that change to SVO in the other tank when the veg-oil is hot enough, and switch back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More details on straight veggie oil systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear benefits over SVO: it works in any diesel, without any conversion or modifications to the engine or the fuel system-- simply put it in and go. It likewise has much better cold-weather properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by lots of long-lasting tests in numerous nations, including millions of miles on the road.

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

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 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 worldwide band of homebrewers don't mind-- they make a supply every week or when a month and quickly get used 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 use because it's cheap or totally free for the taking. With WVO food particles and impurities and water must be gotten rid of, and it most likely should be deacidified too. Biodieselers state, "If I'm going to have to do all that I might as well make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
