Ew, that's nasty Jake! Good thing it was changed.
My fuel filter was last changed 20k ago at 65,000 miles, and isn't due for another 10k at 95,000, but seeing that picture makes me wanna change this weekend!
Even though i'm showing no signs or symptoms Id like to change the O2 sensors and intake/exhaust camshaft sensors as I'm approaching 90k miles.
What do you guys think, wasteful of me to change with no symptoms or no?
