Advantages of 5w30 engine oil in extreme climates

19 December 2023

When it comes to facing extreme climates, choosing the right lubricating oil is essential, which is why it is important to understand the differences between the various SAE grades in their behavior in hot and cold conditions. An oil with the right viscosity will guarantee optimal protection and engine performance, avoiding problems from excessive friction or unnecessary consumption.

In this context, 5w30 engine oil is a popular choice that offers a series of significant advantages in adverse weather conditions, prolonging the engine's useful life, and contributing to its energy efficiency.

What is 5W30 engine oil ?

5w30 engine oil is a multigrade oil, meaning it varies from low to a high viscosity grade. This wide range of viscosity makes it a versatile choice to combat extreme temperature changes.

As we already mentioned in this article, the first number of the SAE (5W) refers to the oil viscosity at low temperatures, which makes it flow better and makes the engine easier to start in winter. And the last number (30) indicates the viscosity at higher temperatures, when the engine is running, ensuring adequate lubrication when the engine warms up.

What are the advantages of 5W30 engine oil?

5w30 oil is one of the most widely used because it is suitable for a broad range of vehicles, engine types, and climates. Let's take a look at what the advantages of this lubricating oil in extreme climates are.

Wide viscosity range: Its range of viscosity helps lubricate and protect internal engine components in different climates. Furthermore, this feature allows for optimum performance in both winter and summer, without the need to carry out oil changes depending on the season. In fact, 5W30 engine oil is capable of operating at temperatures as low as -30ºC and as high as 35ºC.
Greater engine durability: This oil, used in both gasoline and diesel engines, facilitates cold starts, minimizing wear and tear at the critical moment of starting up the engine. Meanwhile, it reduces friction and wear and tear when the engine heats up while driving, which translates into longer life. In turn, thanks to its additives, deposit formation in the engine is reduced, ensuring that the internal components stay clean and in good condition.
Fuel savings: The low viscosity of 5w30 oil also translates into less stress on the oil pump, which reduces internal resistance in the engine and means that it does not need to work as hard to overcome friction. This results in lower fuel consumption since a well-lubricated and protected engine, if operating with less friction, requires less energy.
