I've already done 180 degree drilled thermostat and switch to Prestone. Temp gauge reads lower than before, but since the gauge doesn't seem to be linear, I will have to wait until my scantool gets here to see what my actual temps are (and to make sure I'm not running TOO cool!). I run 10w30 synthetic year-round.
In Southern CA, cold weather is not my issue. It can get blazing hot in summer, especially on the desert side of the mountains and between here and Vegas. That'* the main reason for the t-stat and my questions re: water wetter.
Anyone got anything to say about LubeGard?
