That is just the oil going milky white do to not letting it warm up at proper operating temperatures before driving,basically condensation build up,or the opposite,Pre mature warm up,continuous rev holding to warm up the engine faster,and quicker,and when it cools down in the cold,that is what you get.
So if you are....starting stang,drive to destination,turn off stang, with no warm up when you first start it,then shut it off just as the engine is getting warm,this is the end sesult,especially when the temps out side get colder.Doing this continuously,will obviously leave you what you see right know in those pics.
Or sitting and holding the throttle to warm it up quicker.
Short trips in the cold is the worst on the engine,it doesn't allow time for the engine to warm up to temp "properly".It's like putting a fresh hot meal in the fridge,what happens,it starts to condensate once it hits the cold.So similar situation in one way.LOL!
Up here in the GREAT WHITE NORTH,Canada,you will see that threwout the winter in many cars/trucks.The first time i saw that with my first vehicle in the winter,i was like wtf,and my mechanic at the time explained to me the cause,so now i let my cars warm up a bit before driving,and i get to work a bit ealier,and let the car idle a tad more (since my job is 5 minutes away),this way it allows the engine to get to it's proper temp,and run at proper temp for a bit,then i will shut it off.And i have not seen that issue ever again since doing that.
No matter what oil brand you use,this will continue to happen.
I'm not saying this is what you are doing,but may be part of the reason.
