0W20 vs 5W30 Oil: Which Is The Best Oil?

Based on the viscosity, engine oils are categorized into many types. Among these types, the 0w20 and 5w30 are two. These two types are very popular but many users don’t where are these two types have main differences and where they are the same. To help them know, the 0w20 vs 5w30 discussion is designed.

Here we will talk about both the oil types, where they are better to use, and which one is good for what type of vehicle. So, this is going to be a worthy discussion to read from first to last.

0w20 Vs 5w30 Oil

There are so many things that we can discuss here but some key points should get the most priority in this discussion. Here the main features of these two types of oil are given in the below table based on the comparison.

Besides these, some more differences are there that you need to know to get a better idea about these two oil types. For a better understanding of 0w20 vs 5w30, let’s start with their definition.

What Is 0w20 Motor Oil?

The 0w20 motor oil is a synthetic blend of oils that was designed to provide superior performance and protection in vehicles. It contains 20-weight percent mineral oil, which makes it both long-lasting and versatile.

What Is 5w30 Motor Oil?

5w30 motor oil is a blend of semi-synthetic and synthetic engine oils that are used in manual and automatic transmissions. It’s the most popular type of engine oil among car owners, as it provides good performance and protection at a reasonable price.

Difference Between 0w20 And 5w30 Oil

This section can be said to be the heart of this discussion because here, you will get the main element of 0w20 Vs 5w30. These differences are a must to know to understand why these two types are created and which type of oil will be best for your vehicle.

  • The 0w20 is a synthetic blend of oil while 5w30 is a semi-synthetic oil. Though both works in the same way but the working temperature is different.
  • The viscosity is the main point of difference between these two types of oil. 0w20 has a lower viscosity, making it easier to work with and control; however, 5w30 offers better protection against corrosion and dirt buildup.
  • The 0w20 can work at lower temperatures. And it can keep glow plugs active even if the weather is -40 degrees celsius. On the other hand, 5w30 had a wide working temperature. It can keep transmission smooth from the temperature of -30 to 30 degrees celsius.
  • 0w20 is a lightweight oil that can be used in cold weather conditions while 5w30 is a heavier grade oil designed for use in warmer climates.
  • 5w30 is general-purpose engine oil that is used in many different types of engines. On the other hand, 0w20 is a synthetic motor oil that is designed for high-performance engines.
  • 5w30 is a light oil that helps reduce heat build-up in the engine and provides better fuel economy. But 0w20 better protection against wear and tear and extreme weather conditions.

Some more minor differences are there but they are not worth mentioning. Most of them are talked about here. Besides knowing the differences, we should know the similarities between these two types of oil. It is also important. Let’s see then in the following section of the discussion.

Similarities Between 0w20 Vs 5w30 Oil

The similarities are more than you expected. Because some common issues are drawn here to provide pinpointed detailed picture of similarities. Let’s have a look at what these are.

  • 0w20 and 5w30, both are quality oils that can be used in various engines.
  • To improve engine performance by reducing friction and helping in the lubrication of moving parts, both are experts.
  • Both also prevent metal-to-metal contact, which can result in wear and tear.
  • They are also non-toxic and have low toxicity levels.
  • Both oils are synthetic and heat up quickly in an engine.
  • They can help in reducing engine noise.
  • They both have a low smoke point, so they should not be used in high-performance engines.
  • They both have a smart viscosity index that resists shear and lowers the friction factor in the engine.

Though these are the similarity between these two types of oil, the differences between them are main and you need to know them.


Q: Is 0w20 Better Than 5w30?

Ans: Both have their own good sides. 0w20 is good in its own weather in the same way, 5w30 works best in middle-temperature weather. Thinking of the working temperature range, 5w30 can be called better.

Q: Can I Use 0w20 Oil Instead Of 5w30?

Ans: If you drive your vehicle in a cold area then you can use 0w20 instead of 5w30. But 5w30 will work in hot areas for its viscosity.

Q: Does 0w20 Damage The Engine?

Ans: No, both save the engine from friction and make the transmission smooth. The people who say 0w20 damages the engine are wrong.


While there are many types of motor oils available on the market that may be better suited for your vehicle, 0w20 and 5w30 are often considered the best choice overall due to their versatility and high-performance features. But they have their own features that make them different.

So if you’re looking for the best performance from oil, consider your weather and then select one. Thanks for reading the 0W20 Vs 5W30 Oil discussion, we hope this helped you a lot.
