You have finally seen what oil is like when it's cold.
Now go the other way any get it up to 200 degrees and pour it.
Oil doesn't freeze,,, period.
That's why there is 5W, 10W, and so forth. It's all temperature related how it pours at a given temp.
It's what makes the engine either spin easy or tough as snot to start.
The one factor thats missing is the fact we have fuel injection now thats so perfect, that the engine will fire off regardless how stiff it is.
Now do this back in the 70's or 50's. Your not going anywhere.
If we had to go some where as kids when it was that cold, a fire had to be built under the oil pan. With quilts over the motor to trap the warm air.
Your 50 miles from town.
