What is 5w20?

One of the renowned engine oils used for increasing the lasting time and helping the engine work smoothly is 5w20. The texture and consistency of the engine oil play a big role in determining the weather conditions that would support its results. The consistency of the 5w20 is flowy and thin, which helps it to help the engine work soothingly in a better manner. The thin consistency of the engine oil would not stay in good condition if used in hot weather as heat would make the oil go thinner, affecting its working mechanism.

Therefore, to protect the oil’s quality, people should use the 5w20 engine oil in cool weather so that the oil would hold its texture, quality, and consistency for the longest. The thin or less gummy texture of the 5w20 engine oil would go very smoothly in the engine, reducing the lubrication time.

What is 5w30?

The oil that is popular for its thick and gluey consistency is 5w30 engine oil. This oil would be the best choice for people using it for their engines in hot climatic conditions. The thick and less flowy texture of the 5w30 engine oil would be able to sustain the heat. If used in winter, the heavy or thick texture will get frozen or thicker due to the cool air. The quality of the 5w30 engine oil would be one of the best for making your vehicle’s engine work smoothly.

The oil would take some time to help the engine lubricate as the thick texture would cause a lot of friction. Due to its sticky and thick texture, the oil may cover the whole engine, as some parts may not get lubricated.

Main Differences Between 5w20 and 5w30

  1. The 5w20 engine oil would flow in a faster manner as compared to the 5w30 engine oil.
  2. The 5w20 engine oil would be able to cover all the parts of the vehicle’s engine for lubrication, which may not happen in the case of 5w30 engine oil due to its properties.
  3. 5w20 is an oil meant to enhance the engine’s performance in hot weather conditions. On the other hand, the cool weather calls for the 5w30 engine oil.
  4. The lubrication time for the engine taken by the 5w20 engine oil would be much less than the 5w30 engine oil.
  5. 5w20 is good engine oil but would not be suitable for observing the lubrication effects for a long time. On the other hand, the effects of the 5w30 engine oil would last long if used in summer.


 Engine oils are always the basic requirement of the engine to improve its performance. The person should choose the engine oils wisely as not all the engine oils would go in every weather. Both 5w20 and 5w30 engine oils are good enough to make the engine run efficiently, but they differ due to their texture.

If someone is looking for safe engine oils in slight or extremely hot weather, the 5w30 would always be on the top of the engine oils list. People pondering about engine oil to support the engine’s health during cold climatic conditions should go for the 5w20 without doing much research.
