   The plugs in my Silverado are still factory with 72k on them. Even though   
   they're 10yo, they perform just as good as they did when it had 28k on   
   it, aka the day I bought it.

   Oil will be and is contaminated by water condensation, creating sludge   
   that gathers in crankcases, etc.. Cats will also be cooled by that same   
   condensation, that is, until it gets hot enough to make steam out of   
   it...then it'll exit the system.
