2012s on lots....where are the oil coolers?

It's not to say that "our oil is better than competitor X." It's to gain scientific understanding. You must keep that in mind when reading a scientific journal entry.

Nissan's commercial ester oil they sell very well be outperfromed (depending on metrics) over a given oil change interval by a premium synthetic, a higher quality base oil, especially if it also contains the specific compound that makes this friction magic happen. No arguments there. But without that compound, you don't get that breakthrough in friction reduction.
