It's called polymerization.......Sorta turns the oil into plastic. It's real and it destroys veggie powered engines.
>From what I understand BioDiesel doesn't do the same thing but I could be mistaken. I think I need to look into the analysis a bit more myself as I'd like the old GM 6.2 in my truck to last a while...... My blend of WVO and diesel costs me $1.21 or so per gallon x 20 MPG from a 1 ton crewcab works well for me. At that cost I could easily replace the engine and still make out ahead but I'd rather not.
