|Reg, I have been using both graphite (lock lubricant) and light machine oil successfully for decades as a spark suppressant/contact improver. Both indoors and out.
The graphite method was as a result of the findings of a well known Australian modeller who when moving to the then new Triang TT range in the 50's became frustrated with the poor electrical performance. He found a solution in a suggestion from a local long time O gauge modeller who used powdered graphite to solve the same problem with some cast loco wheels.
This modeller later moved to N gauge and continued the practice that had worked so successfully in TT.His layouts ran reliably with no attention month in month out unlike the rest of us.
Use of a light machine oil such as Wahl hair clipper oil came about as a result of article in a US magazine in the 1970's. Hundreds if not thousands of modellers have used that method since with similar results.
Indoors I normally use the graphite method but outdoors I have given both a try.
Outdoors I first tested with just a clean track to define a baseline for performance. A day or two at best before signs of hesitancy started.
I initially thought the graphite was the longer lasting solution but repeating the tests a year or two later with a little more oil than the first tests proved to change my mind. I am now using the oil outdoors.
I am happy to trade a little adhesive performance of my locos for weeks of trouble free running.
