oil temp debate

After reading through some posts about oil temp issues I began to wonder how big of a problem this is for us Z owners. This issue seems to be consistent with all the Z's not just some. People began to notice the oil temp rising pretty quickly in a short amount of time thus resulting in power loss and throttle lag due to the ecu limiting the cars potential. We all know there are different variables that lead to high oil temp such as weather conditions, driving at high RPMs, etc..but the rate at which the oil is heating is the main concern. Here are a few things that I noticed when I went out for a little experiement. After about 15 minutes of normal driving my oil temp was at 200, I then drove a bit more aggresively and it reached 210. After 25 minutes it was at 220. A bit later it was at 240 and this was when I noticed the first symptoms of high oil temp. I was getting lag in the throttle response but the power was still there. At 250, I felt a noticeable loss in power. I didn't want to go above 250 so I let it rest. After 30-40 minutes of fairly aggressive driving my oil temps hit 250 and I noticed a pretty big loss in power. It was around 85 F. I don't know about you guys but this is a pretty big concern for me, as my Z is a DD and I usually drive long distances on the weekends. I dont always drive aggresively but I do like to enjoy my car. Oil coolers seem to be the only fix for this but I always thought that was only for tracking. Do you guys think its necessary for me to get a oil cooler for street purposes only? Inputs? Thoughts?
