Dead car? Block heater and Synthetic Oil

guangdao

there are a few kinds of BH that help cars start from extreme cold weather,
basically ,  BH keep the car warm by heating up the oil pan-which keeps the engine oil from frozen, or by heating up the coolant/radiator, and keep the engine block warm.
Either way, the engine shall not be frozen with use of BH.

A good synthetic oil, 5w20 or 5w 30 , or 3w 20 have a pure point of -30 to -40 degrees.
