When it comes to engine oil, there are many different types to choose from. Two common types are 0w20 and 5w30. But what exactly is the difference between these two oils, and which one is right for your vehicle? In this article, we will explore the differences between 0w20 and 5w30 oils and help you make an informed decision.
To start, the main difference between 0w20 and 5w30 is the viscosity. Viscosity refers to the thickness or resistance of a liquid to flow. The “w” in the oil’s rating stands for winter, and the number before the “w” indicates the oil’s viscosity at low temperatures. So, 0w20 is thinner than 5w30 at low temperatures.
This means that 0w20 will flow more easily through your engine when it’s cold, which can lead to better fuel efficiency and less wear and tear on your engine. However, 5w30 is thicker at high temperatures, which can provide better protection for your engine in extreme heat.
