Discolored fluid in oil cap and spout.

Just wanted to find out if anyone had seen this before.
I have a 2014 Tacoma with 30k on the clock. I did an oil change on it tonight for the first time since the dealer only gave me a few free oil changes when I first bought the truck. Oil change has been done every 5k by the dealer other than tonight. I opened the oil cap and found this strange colored fliud around the cap and in the spout. Any ideas would be appreciated

 

This was brought up on the fb group a couple weeks ago. Its normal and happens to us guys in colder places

 

Condensation from short drives. It's not a problem and you're not the first to notice.

Go for a long drive (1 hour) and the engine will be hot enough not to produce condensation.

 

Yep, short trips without letting the engine warm is the cause.

 

Thanks all. Much appreciated.

 

Part of the cause is probably the plastic tube/cap - it doesn't get as warm as metal, and what gets left there contains water from humidity from the air.

My Dakota 4.7L V8 had a long plastic oil filler tube and would get this very bad, but only in colder months. It's likely a water/oil emulsion forming from the condensed water and hot oil vapor. I had to wipe out the tube with a rag at every oil change. It was like a light grease.
