After reading the posts on oil foaming and the early Renesis engine foaming problems I believe that is probably what is causing my lack of oil cooling.
I have maintained my oil level at the top of the full mark.  My engine is from an early RX-8 car and the dip stick has the full mark above the pan partng line.
Unfortunatley I will be traveling for the next week and can't try a lower oil level until I get back!!

Does anyone know how much the new Renesis dip stick lowered the oil level?

Bobby - I am in the market for the aluminum wedge pan you have.  Call me when you are back.
