I got a Z1 oil cooler installed today. Mine has a 25 row core, and I got the Mocal thermostatic plate. I got the oil cooler because I intend to track the car. I am not a racer or anything, but I plan to do some HPDEs in the car.

I want to add one more data point to the discussion so that future searchers can make more informed decisions.

Driving from my home to Z1 on the highway prior to getting the cooler installed, (a 3 hour drone with traffic, but no actual stop and go driving, just disappointing highway speeds), my oil temp hung out at around 215 degrees. The ambient temp was mid to high 70s.

The oil temp on the drive to Z1 was consistent with the oil temps I normally see when driving the car on the highway and around town. It will get to 220 or even 225 if I really push it, but on public roads it is difficult to ever push it for very long at a stretch.

Driving the car back home from Z1 - this time a 2.5 hour run with no traffic to speak of and the cruise control on 75 - resulted in the oil temp never actually breaking the 180 mark on the gauge. It warmed up to the 175 line and got just over that, and then it never made it convincingly past 180. Sometimes it would flirt with 180, but it never got over. Temps on the drive in the low to mid 80s.

My conclusion from this is that a 25 row oil cooler is overkill for a DD, as I would actually prefer to see the oil temp a little higher.

As others have suggested, a 200 degree plate would be an improvement.

On another note, I will post a thread about my positive experience at Z1 getting the Z1 track prep package installed in the next day or so. Short version is that I had a positive experience, and I would recommend them to anyone wanting an oil cooler or other mods installed.
