Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- 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 cleaner-- better for the environment and better for health.

If you make it from used cooking oil it's not just cheap however you'll be recycling a problematic waste product. Best of all is the GREAT feeling of liberty, independence and empowerment it will give you. Here's how to do it-- whatever you need to know.

Straight vegetable oil fuel (SVO) systems can be a clean, reliable and cost-effective choice. Unlike biodiesel, with SVO you have to modify the engine. The very best way is to fit a professional singletank SVO system with replacement injectors and optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for example you can utilize petro-diesel, biodiesel or SVO, in any combination. Just begin up and go, stop and switch off, like any other cars and truck. Journey to Forever's Toyota TownAce van utilizes an Elsbett single-tank system. More

There are likewise 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 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.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, without any conversion or modifications to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather properties than SVO (but not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by lots of long-lasting tests in lots of countries, consisting of countless miles on the roadway.

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

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 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 rapidly growing worldwide band of homebrewers do not mind-- they make a supply weekly or when a month and soon get utilized to it. Many have actually been doing it for years.

Anyway you have to process SVO too, especially WVO (waste grease, used, cooked), which many people with SVO systems use since it's cheap or complimentary for the taking. With WVO food particles and impurities and water need to be removed, and it most likely needs to be deacidified too. Biodieselers state, "If I'm going to have to do all that I might too make biodiesel rather." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
