Here's are 2 cents to the debate.. I drive an 2010 7AT 370z, 3,100 miles on the clock.. 2 oil changes w/ Ester so far. It's my weekend ride.
Here in Northern Va, it was 95 degrees and humid today.
I took out the Z for a 125 mile run from Alexandria, VA to West VA (roundtrip) started at 1pm. On the highway, got up to 85mph, and used paddle shifters no traffic, so i opened up the car pretty good. The temp got up to 210, but stayed there for the entire run..
When i went from 85mph > down to like 70mph > back up the temp came down to 190 and stayed put..
I only rested the car for a stop for drinks and gas.. and the car drove beautifully. I wasn't trying to redline the car or anything, but at high speeds, my temps were within the expected range..
I have never tracked it, so I don't know how the car will react, but, this is my weekend ride, and for type of driving i do, I don't think i will get an oil cooler..
