The Nissan Path

I recently used Valvoline full synthetic 5w-30 oil for my last oil change in my 2011 pathfinder with 43k on the odometer. I drove just over 5,000 miles on the oil and upon discarding the used oil I noticed it had a slight (dark) red color to it. Is this a characteristic of Valvoline oil, or do I need to investigate further? I haven't experienced any issues with the vehicle, but at the same time I have never seen used oil come out this color. The first thing that goes through my head is somehow tranny fluid got in there?? I checked the trans fluid and all looks normal. Any helpful hints would be appreciated. Thanks!

You may want to post this on Bobistheoilguy.com the oil guys on that site will prob have a few answers for you.

Doesn't sound abnormal to me. I use NAPA synthetic (which I'm told is Valvoline) often but also Mobil 1 and iirc they both usually come out with a red tint. I've had both sampled and at 10k intervals and they were both extremely clean.
