Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the huge oil business 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 much better for health.
If you make it from used cooking oil it's not just inexpensive however you'll be recycling a frustrating waste item. Most importantly is the GREAT sensation of liberty, self-reliance and empowerment it will give you. Here's how to do it-- whatever you require to know.
Straight grease fuel (SVO) systems can be a tidy, effective and cost-effective option. Unlike biodiesel, with SVO you have to modify the engine. The best way 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 example you can use petro-diesel, biodiesel or SVO, in any mix. Just start up and go, stop and change off, like any other car. Journey to Forever's Toyota 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 start the engine on common 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 switch 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, with no conversion or adjustments to the engine or the fuel system-- just put it in and go. It also has much better cold-weather properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,
it's backed by numerous long-term tests in lots of nations, including millions of miles on the roadway.
Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that numerous SVO systems are still speculative and require additional advancement.
On the other hand, biodiesel can be more pricey, 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 upon where you live). And unlike SVO, it has actually to be processed initially.
But the big and quickly growing worldwide band of homebrewers do not mind-- they make a supply weekly or as soon as a month and quickly get used to it. Many have actually been doing it for years.
Anyway you need to SVO too, especially WVO (waste grease, used, prepared), which lots of people with SVO systems utilize since it's inexpensive or free for the taking. With WVO food particles and impurities and water need to be gotten rid of, and it most likely must be deacidified too. Biodieselers say, "If I'm going to have to do all that I might as well make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
