How Oil Viscosity is Tested

In this video, we explore the fascinating world of engine oil! We'll delve into the science of lubrication, covering key aspects like:
* API Gravity: Understanding how oil density impacts performance.
* Viscosity Measurement: Exploring different methods for determining oil's flow characteristics, including kinematic viscosity and viscosity index.
* Viscosity Testing: Hands-on demonstration of common viscosity tests and their significance.
* Oil Analysis: The importance of used oil analysis for identifying wear metals, contaminants, and overall engine health.
* Fluid Mechanics & Dynamics: How fluid properties like viscosity influence engine performance, fuel efficiency, and wear.
* Lubrication Properties: Examining key oil properties like pour point, flash point, and their impact on engine lubrication.
* Synthetic vs. Conventional: Comparing the advantages and disadvantages of different oil types.
* Best Engine Oil: Factors to consider when selecting the best oil for your vehicle.

Please make second part with same oil examples on work temprature.

Why each one called that way what the W and the 40 means why each one increases with a 5
