- aggressive driving on the street, or lots of high RPM e.g., 1st/2nd/3rd in traffic
- driving over very steep gradients, 6+ degree continuous
- driving in very hot temperatures, 110+F
- manual transmission

The last one is controversial with some folks, but as it turns out if you have a manual transmission, you're much more likely to experience overheating... See data below from our forum survey.... We have basically zero reports of limp mode on the street with automatic transmissions, and very few reports of temps over 260F


This pretty much nails it, IMO. I have a MT, like to drive aggressive (albeit safely) winding out 2nd and 3rd, temps in summer reach 100F air temps, ambient pavement temps hit 115, and.... being on the coast I see a lot of inclines (bridges/steep gradients). This is also combined with a rush hour issue where, after some open road enjoyment, I come to a total standstill and crawl in thick congestion............ I hit 260 all the time in July and August. Now that it's cooler, the most I am seeing is about 240. Looks like an oil cooler for me next spring
