What Is the Difference Between 5w40 and 5w50 Oil?

5w40 and 5w50 motor oils differ in terms of fuel economy, hot weather, and viscosity, so let’s begin by comparing the two.

Viscosity

At 0 degrees Celsius, the oil viscosity of 5w40 motor oil is 5. At 100 degrees Celsius, the w stands for winter, and the 40 indicates the viscosity at that temperature. The velocity of 5w40 and 5w50 motor oils is the primary distinction. The forty is thinner, while the fifty is larger in diameter than the earlier model.

Fuel Economy
