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 huge oil companies sell 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 used cooking oil it's not only inexpensive but you'll be 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 need to know.
Straight grease fuel (SVO) systems can be a tidy, effective and cost-effective option. Unlike biodiesel, with SVO you have to modify the engine. The very best method is to fit an expert singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, along with 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 change off, like any other car. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More
There are also 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 after that 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 advantages 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 better cold-weather residential or commercial properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter season). Unlike SVO,
it's backed by lots of long-term tests in many countries, consisting of millions of miles on the road.
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 further advancement.
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 new oil or used oil (and depending on where you live). And unlike SVO, it needs to be processed first.
But the large and rapidly growing around the world band of homebrewers don't mind-- they make a supply every week or when a month and soon get utilized to it. Many have been doing it for several years.
Anyway you have to process SVO too, particularly WVO (waste grease, utilized, prepared), which lots of people with SVO systems use due to the fact that it's inexpensive or free for the taking. With WVO food particles and impurities and water should be eliminated, and it probably ought to be deacidified too. Biodieselers say, "If I'm going to have to do all that I might as well make biodiesel rather." But SVO types discount that-- it's much less processing than making biodiesel, they state. To each his own.
