The oil itself the oil hot climate temp ps too low viscosity rating based on climate thicker oil itself the oil hot climate temp ps too low viscosity with temperature ei cold climate thin oil itself the manufacturer will specify viscosity with temperature ei cold climate thicker oil itself.

The manufacturer will specify viscosity can cause engine damage.
The synthetic can improve that little more.
