Is it possible I stressed the car by driving it for so long during break-in? I never exceeded 4.5k rpm but I did drive the car for 5-6 hours straight around town trying to get miles done for the break in... the car never over-heated or anything but I am asking this because I have heard mixed opinions on break-in procedures.
I've heard mixed opinions about using sport settings during break-in but I couldn't help myself...1200 miles with just the valves open in efficient mode is pretty bland
All opinions appreciated!
