End of story so far. Fuel test showed very low Cetane rating of my fuel. There was no fuel in the motor oil. Lousy fuel = blown motor, no warranty on the motor. I had a brand new motor installed in my tractor. I picked it up today and it purrs so nice. I don't ever recall it being so quiet. I paid for the motor. Warranty covered eveything else. The CCRT DPF exhaust has been changed, new turbo, new high pressure fuel pump, latest injectors, hoses, filters and everything related to the motor including all sensors, switches etc. On the fuel issue. I almost always buy my fuel from one station. I asked them after I bought my Kioti about their diesel fuel. They told me it was real diesel. After my motor launched I asked them about their diesel again. They said BioDiesel. From my research, a few others here and what the dealer and Kioti Rep told me is that BioDiesel will destory a tractor motor like these and not to use it. NEVER run BioshitDiesel in your tractor. I have ordered a Cetane reading hydrometer for testing my fuel. I will never let this happen again. Taxachusetts does not require gas station to list the Cetane ratings on their fuel pumps or if it is BioDiesel. Big lesson learned on this. I will be complaining to the State AG about making gas stations list the type of fuel that they are selling.
