Thanks for pointing that out, so its like Mobil 1 oil that gets black but still works? makes sense, from all the information I'm going thru, it's also an indicator of high temps that made the color change, what I'm reading is if it stays around 170 190 degrees it should not turn a different color.
I'm going to do an experiment with some clamp on temperature probes, they record the temps every couple minutes, and I can do a graph on a say 40 minute beach cruise, it will be interesting to see just how hot that little trainy runs.
