Pulled my plugs at 60k and they looked fine, pulled them at 90k and wow
Same truck, same gas, but the gap had opened up way past spec and two of them had oil on the threads. Runs smoother cold now. How often are you all actually checking gap instead of just swapping them?
Man, I always just swapped them without checking. Figured the gap was close enough out of the box. Seeing your 90k ones has me rethinking that, guess I'll start gapping them every other oil change or so.
