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 business sell you. Your diesel motor will run better and last longer on your home-made fuel, and it's much better for the environment and much better for health.

If you make it from used cooking oil it's not only inexpensive however you'll be recycling a problematic waste item. Most importantly is the GREAT feeling of liberty, self-reliance and empowerment it will provide you. Here's how to do it-- whatever you require to understand.

Straight vegetable oil fuel (SVO) systems can be a tidy, efficient and cost-effective option. Unlike biodiesel, with SVO you need to modify the engine. The finest 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 mix. Just start up and go, stop and turn off, like any other cars and truck. 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 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 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 lots of long-lasting tests in many nations, including millions of miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that lots of SVO systems are still experimental and need further advancement.

On the other hand, biodiesel can be more expensive, 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 upon where you live). And unlike SVO, it needs to be processed initially.

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

Anyway you need to process SVO too, particularly WVO (waste veggie oil, utilized, cooked), which many people with SVO systems use since it's inexpensive or totally free for the taking. With WVO food particles and pollutants and water must be removed, and it most likely needs to be deacidified too. Biodieselers state, "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 state. To each his own.
