oil overheating unique to vq37vhr engine?

Pharmacist

so basically all cars overheat the oil, but nissan is the only one that bothered to protect the engine and put the limp mode there? that definitely doesn't reflect too good on the other car companies

Nissan changed the way it made bearings (dropped lead out of the formulation) and as a result saw a rise bearing failures at sustained temps over 300. 280 was the point they decided was a good place to limit to give themselves a bit of a buffer. I have no idea oif other car companies have done the same thing with their bearings.

Many vehicles see bearing failures at sustained 300+ temperatures. The oil thins out so much that it can no longer provide adequate film protection to vulnerable parts like bearings. A few weeks ago I was at a hot track event with a C5 Corvette that was continually pushing 300+, and sure enough a few sessions in he had bottom end engine failure.
