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 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 better for health.

If you make it from used cooking oil it's not just low-cost but you'll be recycling a problematic waste product. Most importantly is the GREAT feeling of liberty, self-reliance and empowerment it will give you. Here's how to do it-- whatever you need to understand.

Straight grease fuel (SVO) systems can be a clean, effective and cost-effective choice. Unlike biodiesel, with SVO you need to modify the engine. The best 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 use petro-diesel, biodiesel or SVO, in any combination. Just start up and go, stop and turn off, like any other automobile. 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 normal petroleum diesel or biodiesel in one tank and then 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 grease systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear benefits over SVO: it operates in any diesel, with no conversion or modifications to the engine or the fuel system-- just put it in and go. It likewise has much better cold-weather homes than SVO (but not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by lots of long-lasting tests in numerous nations, including 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 speculative and require more advancement.

On the other hand, biodiesel can be more costly, depending 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 needs to be processed first.

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

Anyway you need to process SVO too, particularly WVO (waste grease, utilized, prepared), which many individuals with SVO systems utilize because it's cheap or for the taking. With WVO food particles and pollutants and water need to be gotten rid of, and it most likely must be deacidified too. Biodieselers say, "If I'm going to need to do all that I may also make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
