I'm inclined to agree with this conclusion.

1) Limp mode would be set at 260F if Nissan was concerned about engine components at this temp

2) synthetic oil is fine at 260F

3) Nissan engineers have said this temperature is fine

All this about engine components being 'soft' and 'degrading' at 260+ seems to be based on people's experiences with other engines. I have yet to see any hard evidence that the 370's VQ engine has metals with melting points near the 260F mark. Aluminum certainly doesn't melt at this temperature...engine parts would have to be made entirely of very soft metals for this temperature to be an issue.

Of the three metals in the technosquare article, only tin has a low melting point.

Aluminum 660 C
Zinc 420 C
Tin 217 C

I highly doubt any part of the metal in the engine is composed MAINLY of tin. If someone knows differently please post the respective component and its relative composition of tin to provide some reputable evidence towards the contrary.
