To expand a bit on Jim's post: The discussion about the tests in 1902 are around page 19 of the Klinger's Clear Creek Memories book. The photo of #6 doing the tests is on page 31.
The part that was interesting to me were the notes that the C&S had interest in new oil wells around the Boulder area and so had a close captive source of the fuel. There were solid business reasons for looking at oil above and beyond not dropping cinders on the heads of the tourists.
So in a fantasy C&S using more oil burners, there is an excuse for increased tank car traffic from the Boulder area. Who knows? Maybe the need for good access to this oil would have allowed acquisition of the Denver, Boulder, and Western by the C&S in order to support this new oil-burning fleet. Just imagine the possibilities if the C&S had acquired the DB&W #30, #31, and #32. Boy! That big motive power would have really... Oh. Wait...
