1. Oil can be emptied from tank cars to storage tanks by one man;
2. Smaller storage space for oil versus coal;
3. Cinder pit and all attendant costs done away with;
4. Oil crane can be placed near water tower so engine can take water and fuel at the same time;
5. Grates and smokebox netting eliminated, reducing air resistance and increasing draft;
6. Large engines are as easy to fire as small engines.
7. Full steam pressure can be maintained at all times regardless of grades;
8. Oil can produce 25% more steam than the max rate for coal;
9. Heating value for oil is fairly constant, while heating value for coal can vary widely.
10. No clinkers with oil;
11. Engine can be turned at terminal in less than 1/2 hour because no cinders to deal with;
12. With oil there is no waste of fuel corresponding to cinder loss with coal;
13. Less waste at the safety valve, due to better regulation of the fire with the oil burner;
14. Fewer fires cause by sparks (although it can and does happen).
