How often do they change the oil on a diesel locomotive?

Santie Oil stocks train engine oil in 40–60-gallon drums or 40–260-gallon totes to help diesel mechanics keep locomotives in top condition. The Federal Railroad Administration requires train engine oil to be changed every 180 days (formerly 92 days), and the time may be extended based on the oil's condition.

1000 miles between refuellings would not be unreasonable for a road locomotive with a 4000 gallon tank averaging 40 mph on a line with a maximum grade of 1%. However I would want refuel before I am running on the bottom third of the tank, so perhaps 700 miles is more realistic.
