in hot oil

Just my opinion, but if there are questions that one is needed by some significant % of the people that buy the car (and there is apparently) then it should be either standard to err on the side of safety and lessening warranty issues coming up.... or in a 'track pkg' that can be purchased and dealer installed. That way everyone is happy. IOW, not everyone is happy running an engine on the bleeding edge of acceptable temperature ranges, just because the engineers say it's possible and the engine will last (at least until the warranty runs out).

Alternative question. If the Z was a plane, would you be satisfied with the oil temp performance/lack of oil cooler as evidenced by multiple peoples reports on this forum? In that case - your life could depend on it - in the car case, it's potentially (only) your pocketbook.
