34 row, thermo plate, bottom 1/4th blocked off during winter, wanna share my personal experience:
During coldest days of last winter, like around 30 to 40 degrees, I would start the car about 30 min before I leave office (just a large window between me and the car, so it's ok). This yielded a 180 degree oil temp by the time I started driving.
About 3-4 min onto the freeway at about 65 mph, i would watch oil temp fall back to and stay at 160 (which commonly believe to be about 180 while circulating within the engine). Still a bit on the cool side.
On cold start, even with the block off plate, it took noticeably longer for oil to climb pass 140 during winter (if getting on the freeway right away) and I would keep rpm not much more than 2k to avoid oil pressure spikes.
I may just slap some tapes over it next winter, quick and easy to remove, instead of doing another block off plate.
