Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the big oil companies 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 utilized cooking oil it's not just cheap but you'll be recycling a problematic waste product. Best of all is the GREAT sensation of flexibility, independence and empowerment it will offer you. Here's how to do it-- whatever you require to understand.

Straight grease fuel (SVO) systems can be a tidy, effective and affordable choice. Unlike biodiesel, with SVO you need to customize the engine. The very best 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 example you can use petro-diesel, biodiesel or SVO, in any mix. Just start up and go, stop and change off, like any other cars and truck. Journey to 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 have to begin the engine on ordinary petroleum diesel or biodiesel in one tank and after that 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 adjustments to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather homes than SVO (but not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in numerous nations, 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 further development.

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 new oil or utilized oil (and depending on where you live). And unlike SVO, it needs to be processed initially.

But the big and quickly growing around the world band of homebrewers do not mind-- they make a supply every week or once a month and soon get used to it. Many have actually been doing it for many years.

Anyway you have to process SVO too, specifically WVO (waste grease, utilized, cooked), which many individuals with SVO systems use due to the fact that it's inexpensive or free for the taking. With WVO food particles and pollutants and water need to be removed, and it probably needs to be deacidified too. Biodieselers state, "If I'm going to have to do all that I might also make biodiesel rather." But SVO types belittle that-- it's much less processing than making biodiesel, they state. To each his own.
