Why does my car struggles to start in the cold?

Cold weather makes the engine hard to start for two main reasons.

First, oil thickens when it's cold, which increases friction and makes it harder for the staner motor to spin the engine.

Cold also slows the chemical reaction in the car's battery, reducing its power output.
