Anybody can make biodiesel. It's easy, 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 better for health.

If you make it from used cooking oil it's not just inexpensive but you'll be a frustrating waste item. Most importantly is the GREAT feeling of freedom, independence and empowerment it will offer you. Here's how to do it-- whatever you need to know.

Straight vegetable oil fuel (SVO) systems can be a tidy, effective and cost-effective choice. 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 utilize petro-diesel, biodiesel or SVO, in any combination. Just begin up and go, stop and change 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 thinner. You need to start the engine on ordinary petroleum diesel or biodiesel in one tank and after that 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 advantages over SVO: it works in any diesel, with no conversion or modifications to the engine or the fuel system-- simply put it in and go. It also has much better cold-weather homes than SVO (however not as great as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

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

On the other hand, biodiesel can be more pricey, depending how much you make, what you make it from and whether you're comparing it with brand-new oil or utilized oil (and depending upon where you live). And unlike SVO, it has actually to be processed first.

But the large and rapidly growing around the world 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 many years.

Anyway you need to process SVO too, specifically WVO (waste grease, used, cooked), which lots of people with SVO systems utilize due to the fact that it's low-cost or complimentary for the taking. With WVO food particles and pollutants and water need to be removed, and it most likely needs to be deacidified too. Biodieselers say, "If I'm going to have to do all that I might also make biodiesel instead." But SVO types discount that-- it's much less processing than making biodiesel, they say. To each his own.
