If you do not have BH on ur car, by using synthetic oil you can also prevent oil frozen from happening.
A good synthetic oil, 5w20 or 5w 30 , or 3w 20 have a pure point of -30 to -40 degrees.

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.
