Oil temp question

Push370zzz

Looks like you may have already gotten things figured out, but FWIW, I have a 13 with the factory oil cooler. I recently added a 25 row Stillen oil cooler and am using Mobil 1 5w-30. Prior to the oil cooler, I would hit 210-230 with spirited driving in town depending on ambient temp. Now, it will stay right at 180 on the highway, 190-200 with spirited driving regardless of outside temp.

On the track, I was out for sessions of 15 minutes each. I was flooring it through all but braking/corner entrances and temps never broke 255. I actually like keeping the factory oil cooler because it helps keep coolant/oil temps consistent and actually heats the oil up to operating temp much quicker. The factory oil cooler does have one drawback, which is that it makes it very difficult to route cooler lines and the oil filter is very difficult to access compared to normal. That said, it takes maybe 1 minute to remove the oil filter whereas before it was 15 seconds. Happy with everything thus far.
