Play around with this. http://www.ebicom.net/kitchen/page/tempconv.htm 150 Celsius is 305 Degrees Fahrenheit, pretty stinking hot -------------------- You say ----------*Most SAE 20-50 oils can effectively lubricate at at sump temperature of 150C. The bearing areas run hotter but are not conveniently measured. If we maintain an equilibrium below 150C under most operating conditions the amount of oil in the crankcase doesn't matter. BUT, an optimum level will PRODUCE less heat from crankcase splash and still supply a volume sufficient for cooling as each oil molecule on the average has longer to cool in the crankcase before being pumped into the higher temperature bearing regions.* -------------------- How much below 150c? Running 150 Celsius oil temperature oil is a great way to kill an air cooled engine. I try to keep my celsius oil temp down to 100c or 120c and I've never seen it over 130c (266f) Thanks for your help.
