Pink plugs?
Just curious:
I swapped out my stock (15K mile) plugs last week. They all had pink coloring on parts of the insulator.
What's that from?
The only info I've dug up suggests I've been running some fuel injection cleaner or something. I haven't.
Is it something in the gas? I run 93 all the time. No specific brand. We have MTBE here with different oxygen levels in winter and summer.
