Ok, but did you know that the pontiac torrent's engine is made in china presumably from chinese steel and iron.
It says all steel supplies...one assumes that QA is on top of the quality issue in specified engines runs. However, it is fuel for thought.
My BIL used to have a crass name for steel nails made in Taiwan, S. Korea, or Japan. The nails would bend and snap when hammered. He bought only North American brands.
