Judged by their viscosity, 5w30 tends to be more liquid and better suited for cold weather use. So, thicker oil is preferable to protect these car parts. (Answer Explained)Continue, As an Amazon Associate, I earn from qualifying purchases. The first number, 5 or 10 indicated on these oils stands for the viscosity, or how easily the oil pours at low temperatures. So now, let us differentiate the 5w30 motor oil and the 10w40 motor oil in terms of viscosity, hot weather, and fuel economy.

The first number refers to viscosity at low temperature and the second number, which sits after w, refers to the viscosity level at a higher or warm temperature. For newer engines, it is better to use 5w. To answer it shortly, viscosity refers to the thickness of any liquid and is measured with water as the standard viscosity level. If we talk about the viscosity of the oil, 10W-40 is a bit thicker than 5W-30. But in actuality, it finds the thinness as well.
