5w30 Vs 10w30: Which One Is better?

Are you finding 5w30 and 10w30 lubricating oils the same? Are you confused about which oil is best suitable for your vehicle? Choosing the right type of oil for your vehicle is crucial. This article will unfold about which oil is the best.

As these two oils vary in terms of their thickness, this marks one of the key features to rank them. 10w30 should be used in the winters instead of 5w30. 5w30 is thinner if compared between the two and its performance will be better in the summers.

It is important to use the manual before using any lubricating oil. If they have prescribed oil, refer that oil only.

Don’t use any other oil. Let’s start reading!

What does the number mean?

Most people think that all the lubricating oils are the same. But they are might be wrong if we go with the advice of experts. The life of the vehicle is depended on up the oil you are using. The right quality of oil can enhance the life span of the engine and vice versa.

Just like normal people, if you are wondering what kind of name are these. But here we have a real logic and a fun fact!

5 or 10 (a letter before the W): It refers to the viscosity of the oil at low temperatures.

W stands for the winter.

30(a letter after W): the viscosity of the oil at high temperatures (100 °C).

Engine oil, motor oil or the engine lubricant all are same, one way to understand engine oils is to characterise them by their viscosity.

The Key Difference Between 5w30 And 10w30

5w30:

Less viscosity.
The most suitable temperature for the oil ranges from -30 to 35-degree celsius.
Mostly used in gasoline and petroleum engines.
Provides smooth start in cold weather.
In lower temperature, the oil is mostly thin.

10w30:

High viscosity.
The most suitable temperature for the oil ranges from -18 to 30 degree Celsius.
Mostly used in a truck or heavy weight lifting engines.
Provides smooth and better sealing action.
In lower temperature, the oil is mostly thick.

Understanding The Importance:

The main agenda for using the lubricating oils is to reduce the friction between the different parts of the vehicle to the engine and increasing the life span.

They hold a very important part for normal and accurate functioning by flaming the fuel inside the engine body which is also called as internal combination engines.

As the fuel has to be burnt within the engine, they require a high temperature of around 600 degree Celsius.

Categories Of Oil Division:

The society of Automotive engines (SAE) ranks the oils on the basis on their viscosity and gives them a specific numerical grade accordingly. If more the thickness of the oil, higher the rank and better the grade of the oil.

The oils are further divided into the two categories i.e. single grade and multi-grade.

Single grade oils as the name suggest the soil consisting of only one viscosity grade.

Multi-grade oil refers to the oil consisting of more than one or two viscosity grade. It is usually denoted by “w” in it. As the oil consists of two viscosities, one refers to the cold temperature while the other is for the warm temperature.

Both of the oils are the example of multi-grade engine oils.

10w30:

As the soil is an example of multi-grade engine oil. 10 refer to the viscosity at low temperature and 30 at the higher temperature. This shows that oil will be thin at low temperature.

The oil is certified from API SN, ACEA. Meaning, oil has been met by the certain specification made by the companies to keep a check on the quality of the product.

Key features:

To reduce the wear and tear and the friction between the moving parts of the engine, the oil forms the continuous layer which further protects the engine from being too hot.
On increasing the life of the engine, it further protects it from the rust.
It ensures the smooth and the noise-free working of the engine.
It can be used with advancing fuels like biofuels.

Uses of 10w30:

The oil is best suitable in the summer season. Although, it can be used for starting the vehicles in the winters season.
It is mostly used in the vehicles which are associated with some heavy weight lifting.

5w30:

The name of the oil suggests that the viscosity grade in lower temperature is 5 and in higher temperature are 30. The lower grade of viscosity suggests that the oil will stay thin in such weather conditions and thick in higher temperature conditions.

The oil has gained ASI SN, ACEA and MB approval but depending upon the brand.

Key specification:

The oil tries to maintain its properties even if the weather conditions are getting worse.
It tries to ensure the minimum oil wastage and uses in a small amount.
The oil forms multiple layers over the moving parts and the engine to avoid friction and wear and tear.
It tries to avoid the engine from being too hot.
For increasing the life of the engine, it prevents rust.

Uses of 5w30:

The oil is mostly used in light-duty engines like petroleum and gasoline engines.
It is better suitable for cold temperatures.

Conclusion:

Engine oil defines the life of the engine. The main purpose of the oil is to reduce friction and protects the engine. 5w30 works best in the summer climate with light-duty engines whereas in the winters 10w30 works at its best with the heavily loaded engines.

10w30 can also be used for the engines which are old as it provides better sealing actions.
