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.

if you have BH or SO, but ur car still could not be started up, and you have not checked/replaced your battary before the winter came, I bet the battary is dead.
