I have a DX55, and it's been dicussed here many times the 55's run with their temp gauge at the bottom edge of the normal range. Mine typically runs right on the edge, within the normal band by a hair, even when brush hogging on a hot summer day.
This week the temperatures have dipped to the lower 20's. I added a double shot of Power Service to the fuel, per the instruction on the white bottle. I was hauling firewood in the front end loader, with it sitting at idle half the time. I noticed the temp gauge was at least 1/4 way into the normal zone for the first time. The outside temperature was in the 40's. Just thought it was interseting it rasied the operating temperature that much, which is good in the winter.
