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 big oil business sell you. Your diesel motor will run 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 cheap but you'll be recycling a problematic waste item. Most importantly is the GREAT sensation of freedom, independence and empowerment it will offer you. Here's how to do it-- everything you require to know.

Straight veggie oil fuel (SVO) systems can be a clean, efficient and affordable alternative. Unlike biodiesel, with SVO you have to customize the engine. The very best way is to fit an expert singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for instance you can use petro-diesel, biodiesel or SVO, in any mix. Just begin up and go, stop and turn off, like any other automobile. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are likewise two-tank SVO systems which pre-heat the oil to make it . You have to begin 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 change 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, without any conversion or modifications to the engine or the fuel system-- simply put it in and go. It also has much better cold-weather properties than SVO (however not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that numerous SVO systems are still experimental and need more 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 utilized oil (and depending on where you live). And unlike SVO, it needs to be processed initially.

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

Anyway you have to process SVO too, particularly WVO (waste grease, utilized, cooked), which many individuals with SVO systems utilize because it's cheap or totally free for the taking. With WVO food particles and impurities and water need to be eliminated, 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 instead." But SVO types belittle that-- it's much less processing than making biodiesel, they state. To each his own.
