Anybody can make biodiesel. It's simple, you can make it in your kitchen-- and it's BETTER than the petro-diesel fuel the huge oil companies sell you. Your diesel motor will run better and last longer on your home-made fuel, and it's much cleaner-- better for the environment and much better for health.
If you make it from used cooking oil it's not only low-cost but you'll be recycling a frustrating waste item. Best of all is the GREAT sensation of freedom, independence and empowerment it will provide you. Here's how to do it-- everything you require to know.
Straight grease fuel (SVO) systems can be a tidy, effective and cost-effective choice. Unlike biodiesel, with SVO you have to modify the engine. The 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 example you can utilize petro-diesel, biodiesel or SVO, in any mix. Just start up and go, stop and turn off, like any other car. Journey to Forever's Toyota TownAce van utilizes an Elsbett single-tank system. More
There are likewise two-tank SVO systems which the oil to make it thinner. You have to begin 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 switch back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.
More details on straight veggie oil systems in my blog site.
3. Biodiesel or SVO?
Biodiesel has some clear benefits over SVO: it works in any diesel, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has better cold-weather properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,
it's backed by numerous long-lasting tests in many countries, consisting of countless miles on the roadway.
Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's reasonable to say that many SVO systems are still speculative and need 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 new oil or utilized oil (and depending on where you live). And unlike SVO, it needs to be processed first.
But the big and quickly growing worldwide band of homebrewers don't mind-- they make a supply weekly or when a month and soon get used to it. Many have been doing it for years.
Anyway you need to process SVO too, especially WVO (waste grease, utilized, prepared), which lots of people with SVO systems use because it's inexpensive or complimentary for the taking. With WVO food particles and impurities and water must be gotten rid of, and it most likely 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 say. To each his own.
