Oil comes up to temp fairly quickly and when it is around 205 it comes back down to 190 ish with in a minute or so. From what I’m seeing summer temps would increase maybe 20-25 more degrees across the board on the hottest days . The factory cooler definitely does assist the A to A cooler and works great in cold weather bringing the oil temp up.
