Biodiesel is a fuel that can be used directly in any diesel engine generally
without modification. It's viscosity is twice that of regular diesel fuel which means it is better at lubricating your diesel engine than regular diesel. And... emissions are cut dramatically vs using standard diesel fuel. You can buy
Biodiesel already made. Your other option is to make it yourself using your own homemade equipment or by purchasing something like a Fuelmeister biodiesel processor. It costs $2995, but it comes with everything you need to make many, many
gallons of biodiesel fuel. One other option is to burn straight vegetable oil (SVO) in your diesel engine. To do this, you must do three things: 1) You must pre-heat your vegetable oil including the storage tank and all feed lines, 2)
You must start your engine using regular diesel or biodiesel, and 3) You must clean your system by burning only regular diesel or biodiesel before shutting the engine off. I don't recommend the SVO method because there is the possibility of
carbon buildup in the long run and that may damage your engine. Here are the instructions on making your own biodiesel...
WARNING!!!! - Methanol is flammable and toxic. Do not let it touch your skin or get in your eyes. Wear proper protective gloves, clothing, and eyewear at all times. Same thing with ethanol. Lye is also very caustic - do not allow it to touch your skin or clothing. When you mix the lye with the alcohol, it creates an even more toxic substance and toxic fumes which you should be very careful with - do not come into contact with it in any way. Always be in a well ventilated area. Also... you are 100% responsible for your own safety. The author is not responsible in any way whatsoever for personal injury or damage to your engine.
Here is a general description of how to make biodiesel fuel using methanol, lye, and used cooking oil. This process is called transesterification.You can buy methanol from your local racetrack or chemical supply store. You can buy granulated lye (sodium hydroxide) from your local grocery store or hardware store. Make sure you filter the used cooking oil before using. Fry oil filters can be purchased in any good restaurant supply store. The oil also must be warmed up so it is not solid or lumpy or thick. You can use the sun to heat the oil or some kind of water heating element or a electric or gas burner of some sort. The ideal temperature is 120° F. If you are using flames, remember that the methanol is extremely flammable and you should turn your burner off before getting the methanol mixture anywhere near it. Of course, this should all be done in a well ventilated area too.
Two more things....
1) You might be wondering... what kind of engine I need to use biodiesel... basically, biodiesel will run in any diesel engine unmodified. Biodiesel is
a solvent, so if you put it in an old tank or use it with a diesel engine that has been running regular diesel, it may clean and dissolve some "residues"
and then the residues will clog your fuel filter. Changing the filter often when you first start using biodiesel usually fixes this problem. Usually,
manufacturers warranties are not voided when biodiesel is used, but check with your manufacturer to make sure. Sometimes a blend like B20 is
required (20% biodiesel). If you are running straight vegetable oil (SVO), then you need to make modifications to pre-heat the oil to decrease its viscosity.
2) The only other problem you might have is with natural rubber gaskets and hoses in vehicles made prior to 1992. The biodiesel may degrade these types of rubber and they may need replacing after a while. Newer engines have been modified (synthetic rubber) to stand up to the newer blends of diesel fuel that have been in use since 1992 and these engines will work fine with biodiesel
