It is my understanding that oil needs to get up around 195 F or so to evaporate any water out. Oil viscosity is measured at 100 C, or 212 F, considered the temperature of a "warmed up" engine. Keeping the oil too cool is no better than letting it get too hot, because it is designed to work in a certain temperature range. My question would be where the temperature should be measured. Does one measure in the sump, in the little "pool" in the head on the Savage/S40, or somewhere else? I think the hottest oil is found on the rings, but it would be difficult to measure it there. The simple air-cooled engine doesn't have any way to control the oil temperature, anyway.
