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.
