Vegetable Oil and Alternative Fuels
Diesel trucks and cars can run very well on used vegetable oil, used transmission fluid, used motor oil, among other carbon based liquids. The processing of these alternative fuels and some modifications to the vehicle are paramount to your success. I am not selling anything here. Use this information at your own risk. Posts are listed newest first, but if you scroll down to the right and start at the oldest, the information will be in order for the newcomers to veggy oil.

Heat your home with waste vegetable oil
Yes, you can heat your home with the same alternative fuels you can put into your vehicle. The processing is about the same and when you come across some oil you would rather not put into your truck or car, you can save it for your oil heater. Post a question and I will be glad to answer,
Your Diesel to a Veggy Burner
I have a number of Chevrolet 6.5 turbo diesels. In choosing the type of processing you want to use, you must consider your vehicle. The one truck I ran the most on veggy is my 1998 Chevrolet K3500 6.5 Diesel. These trucks have an electronic injector pump. This is a Stanadyne electronic injector pump. I used a blending method initially and I got the idea from “Diesel Secret.” This was a mistake, plain and simple. Although the blending method is viable, the factory electronic setup gave me big problems. I became a wiz at replacing injector pumps until I got smart. I knew that the optic sensor was clouding up and fouling and that I had to go mechanical. After much blogging and being told that it could not be done, I retrofitted my 1998 K3500 to a DB2 Stanadyne IP and never looked back. This is 1993 technology fitted to my electronic setup. Many diesel guys told me that the transmission would not shift if I took away the IP control from the computer. This made no sense to me, so I went forward and with great results. Now I burn used veggy, used motor oil, used transmission fluid. My truck is a little dumper, so I have complete access to the tank, which came in handy as I had to clean it out many times. It was the blending process that was at fault. I would not advocate the “Diesel Secret” to anyone. My journey was documented in several locations online:

My Retrofit Mechanical Injector Pump replacing the Electronic Injector Pump
  
I have conversed with several guys using the titration method without issue on the newer IP’s and even the common-rail injector systems. I have spoken to guys that burn motor oil and tranny fluid without issue. I would suggest that you proceed carefully if you have a newer system, from 1994 onward. For those with later models, I would suggest the titration or salt & baking soda method. I will go into that later.
Acquiring the Oil
You will need 50 gallon drums and a dolly to move them around. The pump to use for obtaining the oil is a Macerator Self-Priming Pump. This is a pump for cleaning out boat toilet tanks. For under $150 and some swimming pool hose, this setup will suck out any grease-pit. I have not found any other method that works and I have tried a few. Forget the hand pumps and any other pump out there.
This pump can be used to transfer your oil. The pumps usually shut down after 15 minutes of continuous use to save the pump. In that time, you can transfer 200 gallons. You will need a truck and some heavy truck straps to secure your tanks. The last thing you want is veggy oil all over the road and a hazmat crew on site with the cops siting you with a major oil spill.
Processing Vegetable Oil for Diesel Fuel
The three methods used are:
1. Titration method.
2. Blending method.
3. Salt & Baking Soda method.
I will discuss all three methods in later posts. As far as alterations to your vehicle, you must first decide which method is best for your vehicle based on the type of fuel injection system you have in your vehicle. I speak from experience with the Chevrolet 6.5 turbo diesel.
Peanut Oil was the Original Diesel Fuel
Vegetable oil is the most puzzling item on the list and information is spotty online for this application. As one who knows and has been through the troubles of trying to turn out a reliable fuel from this stuff, I can enlighten you in your quest for information. First, we have to discuss the several methods and the reasons for them. Second, we must discuss the alterations that have to be made to your vehicle in order to run your finished product.
In order for used vegetable oil to be made into fuel, you must first acquire the product. There are also pumps that you should use that will help you in you acquiring of the product. I will discuss this a little later in a subsequent posting. Used vegetable oil is readily available and obtaining it is simple but it is messy, so be prepared. You can go a long way to keeping your operation clean with a few simple methods that I will discuss in a later post.
Vegetable as Alternative Fuel
Did you know that Mr. Diesel invented his engine to run on peanut oil? Did you know that modern diesel fuel is a byproduct of modern petroleum refining? Diesel was cheaper than gasoline for a long time prior to the environmentalist driven removal of sulfur from the product. When the new low-sulfur product emerged, it was more expensive and it was stripped of its natural lubricating properties. The diesel engine injector system is full of moving parts that are designed to be lubricated by the fuel. This is no longer possible using modern low-sulfur diesel. This is also the reason that alternative carbon based liquid that lubricates the engine is far better for the moving parts of the injector system.
There are limitations to the use of the vegetable oil fuel product in newer engines and the type of processing you use will depend upon your vehicle.
