Now my oil temp never moves off 230 degrees.

The Cummins tech told me that the oil thermostats were 239 degrees so 230 is about right.
Oil was tested and showed chemicals consistent with coolant. When the oil changer poked holes in the oil filter some green fluid came out before the oil.
When I took it to Cummins they said troubleshooting the problem took several steps. I was fully aware that changing the thermostats may not fix the problem. I am not making much money at this yet so I am careful not to spend more than I have to. I guess I havent spent enough yet.
