My car just turned 5000 miles; so it is broken in. I see temps in the 220 to 260 range virtually every day. Once the air temp goes over 85 or 90, oil temps increase to these levels, whenever I maintain highway speeds and normal rpm ranges. I guess the real question is: what is considered "high" for oil temp under normal operating conditions, for street driving? For this type of car, I would hope that shifting at 5K RPM would not cause a problem. After all, it is a sports/high performance car. Cruising at 70 to 80 mph and turning 3500 rpm shouldn't result in 250 degree oil temps; at least not for any other car I've driven in the past. Any insight you can provide would be greatly appreciated.
