Well, I was checking my oil and stuff while I was adding washer fluid this morning, and for the first time, at 33K, I was down to the add mark on the dipstick, so I went to add a half quart of Mobil 1. When I unscrewed the oil filler cap, there was a little moisture inside, just clear water drops, no "scuzz", but the entire inside of the filler cap was coated with this brick red stuff, almost like it's painted on. It's not rust, and it doesn't rub off with a paper towel. I've never seen anything like it before.
Is this the way it normally is, or is this something I should ask about when I take it to the dealer for it's last visit before the bumper to bumper warranty expires?
TIA,
