Yes I had oil in the fuel. Berry says that diesel is fine in the Kingtech. I am going to give it a go in this turbine.
It will be interesting to see what kind of thrust the 140 has at sea level. I saw one on you tube that was putting out over 32 lbs of thrust. I am very happy with 25lbs 10oz to 14oz thrust at my 7400 ft alt. George
