Anybody can make biodiesel. It's easy, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the huge oil business offer you. Your diesel motor will run much 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 utilized cooking oil it's not only low-cost however you'll be recycling a problematic waste product. Most importantly is the GREAT sensation of freedom, independence and empowerment it will provide you. Here's how to do it-- everything you need to understand.

Straight grease fuel (SVO) systems can be a tidy, efficient and cost-effective alternative. Unlike biodiesel, with SVO you have to modify the engine. The very 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 circumstances you can utilize petro-diesel, biodiesel or SVO, in any mix. 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 need to start the engine on ordinary 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 site.

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 residential or commercial properties than SVO (but not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

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

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that lots of SVO systems are still experimental and require 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 upon where you live). And unlike SVO, it has actually to be processed first.

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

Anyway you have to process SVO too, especially WVO (waste grease, utilized, cooked), which lots of people with SVO systems use due to the fact that it's cheap or for the taking. With WVO food particles and impurities and water need to be removed, and it probably must be deacidified too. Biodieselers say, "If I'm going to have to do all that I may as well make biodiesel rather." But SVO types belittle that-- it's much less processing than making biodiesel, they state. To each his own.
