This is a long story, but I may get into it later. I have been surfing these forums a long time. I have read all the post about the 2 cycle oil to diesel fuel. I have an '02 7.3L Super Duty Lariet. I Filled up with diesel last Friday. I did not do any long drives, just a couple to our farm and back. Day before yesterday, I headed out to Tractor Supply, approx. 9 miles down the road the engine just quit in middle of road. I called a tow truck, took to a ford dealer that I use. Said I threw a bad CPS code. Changed it out, I picked it up. Truck started well, seemed to be a bit "rough" running, but not really bad. About 7 or 8 miles from dealership, truck died in middle of highway. Had towed back to dealership. I have been having trouble with this truck approx. 2 months, of not starting when hot, or not starting at all, but that is whole nother ballgame. No one has found out that problem yet. Please tell me that I did not cause this current problem adding tht 2 cycle motor oil! Regards in advance, Trisha
