I'll see how it does on my 180 mile trip again tomorrow.
I'm at just under 17K miles on my 2012, also average low 30's tank/tank. I've had the idle drop off, resulting in a shudder a few times during parking maneuvers. Could be the idle speed not kicking up enough to compensate for the load put on the engine from the power steering pump? Dunno. It hasn't happened enough for me to pursue further.
Royal Purple is good stuff. I used it years ago. I'm doing ~7K mile oil change intervals with Napa Full synth.
