Jake. Very interseting stuff. Is there a theory as to what exact mechanism is causing the loss of oil pressure at elevated temperatures? It is not entirely clear me unless it has to do with oil pump efficiencies/effectiveness under less viscous conditions. Would your transducer placement potentially play a role in the trends you see ?'
