Circling back to the original intention of this post, I replaced all 8 injectors (2013 car, EU5 injectors) at 70k miles and as preventative maintenance. After removal and inspection, there were no obvious signs of leaking. I also replaced the MAF's at the same time so I can't say with certainty which parts were getting tired, but the car's driveability improved after the work.
That's a good sign that the old injectors appeared leak free on your '13 and dispels the rumour further that EU5 injectors are prone to failure more than the 6's.
