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-- better for the environment and much better for health.

If you make it from used cooking oil it's not only low-cost however you'll be recycling a problematic waste item. Most importantly is the GREAT feeling of flexibility, independence and empowerment it will offer you. Here's how to do it-- whatever you need to understand.

Straight grease fuel (SVO) systems can be a tidy, reliable and cost-effective alternative. Unlike biodiesel, with SVO you need to modify the engine. The very best way is to fit an expert 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 combination. Just start up and go, stop and turn 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 need to start the engine on common petroleum diesel or biodiesel in one tank and then change to SVO in the other tank when the 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 advantages over SVO: it works in any diesel, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has much better cold-weather homes than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,

it's backed by many long-term tests in many countries, consisting of millions of miles on the roadway.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that numerous SVO systems are still speculative and need additional advancement.

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

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

Anyway you need to process SVO too, especially WVO (waste grease, utilized, cooked), which lots of people with SVO systems use because it's inexpensive or totally free for the taking. With WVO food particles and impurities and water need to be removed, and it most likely should be deacidified too. Biodieselers say, "If I'm going to have to do all that I may too make biodiesel instead." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
