Anybody can make biodiesel. It's easy, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the big oil companies sell you. Your diesel motor will run much 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 only low-cost but you'll be recycling a problematic waste product. Best of all is the GREAT feeling of freedom, independence and empowerment it will offer you. Here's how to do it-- everything you require to understand.

Straight grease fuel (SVO) systems can be a clean, reliable and affordable option. Unlike biodiesel, with SVO you have to customize the engine. The 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 mix. Just launch and go, stop and switch off, like any other cars and truck. 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 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. 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 also has much better cold-weather properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that many SVO systems are still experimental and require additional development.

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 brand-new oil or utilized oil (and depending on where you live). And unlike SVO, it has actually to be processed first.

But the big and rapidly growing around the world band of homebrewers don't mind-- they make a supply every week or as soon as a month and soon get utilized to it. Many have been doing it for years.

Anyway you need to process SVO too, specifically WVO (waste grease, used, prepared), which many people with SVO systems utilize due to the fact that it's cheap or free for the taking. With WVO food particles and impurities and water must be gotten rid of, and it most likely must be deacidified too. Biodieselers state, "If I'm going to need to do all that I might as well make biodiesel rather." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
