Is Synthetic Oil Actually Better – A Demonstration And Explanation Of Its Benefits

Today we are going to see which motor oil is better – the synthetic or the conventional? The guy from the video had Pennzoil as a sponsor for this video and that’s why he is using Pennzoil motor oils for the demonstration. There is something that you must be aware of before proceeding with the video – viscosity. This is the resistance of the oil to flow. In other words a greater viscosity means more resistance to flow. A greater viscosity means a thicker oil as well. On the other hand the lower viscosity stays for thinner oil and less resistance to flow. We are going to start with the rating system used for motor oils.

If you are about to buy a motor oil you will find lots of bottles with something like this written on the labels of the bottles – 5W-30, 0W-20, etc. Motor oils with viscosity rating like this 5W-40, for example, means that it is a multi-grade viscosity oil. The viscosity grade of such motor oils changes with temperature. The first number (ending with W) is the number for the cold rating. The letter ‘W’ stays for ‘winter’. If we take 5W-30, for example, it’s going to behave like SAE 5 grade motor oil when cold. When reaching its operating temperature (about 100 degrees C), it operates like an SAE 30 grade motor oil.

You might be thinking that the oil would get thicker at higher temperatures, but this is not the case.

One important thing to mention is the low viscosity at low temperatures. This is the point where a significant amount of engine wear occurs.
