(yes, I realize that might depend on air temperature and RPMs)

I just went through a few of my logs and found one that starts with the coolant at 114F and oil at 94F. About 6 minutes into the drive the coolant plateaued at 190F. When the coolant first reached 190F the oil was at 158.5F. It took an additional 3 minutes for the oil to stabilize at 185.46F. So in this case it took me 8mins total to reach normal oil temps. But this isn't from a completely cold start. Also IAT was around 78F so this wasn't in cold weather, even for Florida.
Tomorrow morning I will do a log from being completely cold and post the results.
One other thing, I feel like I've read that the water temp gauge on this car climbs up and then stopped just before the middle mark and from there it stops moving even though the temp hasn't reached 190. The gauge only moves above the midpoint if the coolant goes way over 190. When I do my log tomorrow I will take a timestamp when the needle first hits the 1/4 mark and another timestamp right when it hits it's normal resting place and then compare these timestamps to the real data.
