Temps reached the teens amd my truck wouldn't start the engine wouldn't even turn over and acted like it was froze up. So I turned on key and engine and transf fluid temp showed 19 degrees pulled oil dip stick and oil appears to be froze on dip stick. I have since plugged in the heater but with Temps only reaching the teen I didn't think this would really effect the oil. This truck has been in this Temps multiple times and never had this issue before. Does this sound right?

 

Unless you have water contamination in your oil, I seriously doubt this is an oil issue. My bet is battery.

 

Looks like oil was fine other than dip stick. My passenger side battery and or cables seems to be issue. Voltage was low so I tried jump starting truck at drivers side battery but made no difference, jump started at passenger side and it fired up.
