For a street car, would driving at 80-90 mph for 7-9 hrs cause internal temps to come close to those temps? Or would it require the abuse of track use to reach those elevated temps? I always monitor my coolant temp but have no idea what my oil temp is at during my interstate drives.
I've been chaning my oil every 5k miles and I reach that in two to three months.
