Can I use 10w30 Instead of 5w30? 10w30 vs 5w30

You may find yourself in an existential predicament the next time you go to change the oil in your car because there are so many different options and you don’t fully understand what each one is. The most popular oils are 5w30 and 10w30, and today at we will explain the differences between the two oils.

What is a Multigrade Oil?

Today most cars and trucks work with multigrade oils both 5w30 and 10w30 are multigrade oils but what is a multigrade oil is one that is designed to work efficiently at both low and high temperatures.

Difference between 5w30 and 10w30

Two factors need to be considered when determining which type of oil between 5w-30 and 10w-30 is best suited for your car: the environment in which it resides and the number of years or hours of use the engine has received.

5W-30 Designed to work

Specifically, 5w30 is designed to work effectively at temperatures ranging from 30 to 35°C, making it an ideal choice for those living in regions where temperatures drop too low in the winter and rise too high in the summer.

10w-30 Designed to work

The 10w30, on the other hand, does not have the same capacity and does not have the same working temperature range, as it works effectively from about 18 degrees Celsius up to 30 degrees Celsius in high temperatures.


Viscosity is the resistance that a liquid has to flow and this is quite important in oils because it determines the performance and the capacity it has to protect the engine and its parts.

Higher viscosity oils such as 10w30 tend to flow slower at low temperatures than oils such as 5w30 which tend to flow faster at low temperatures, however, the more viscous oils such as 10w30 for this same factor protect the engine parts more efficiently.

A high-speed oil will be a better sealant, it will seal the engine better and in addition, it will provide better lubrication to critical engine parts. Engine oil also plays a very important role in gasoline consumption, logically, an oil that is more viscous makes the engine work harder, therefore that oil makes the gasoline consumption higher, that is to say, it reduces the efficiency of gasoline consumption.

Can I Use 10W30 Instead Of 5W30?

The use of high viscosity oil can lead to increased resistance and excessive oil temperature since thick oil does not transfer heat better than thin oils. On the other hand, using oil with a lower viscosity than required for your vehicle will cause oil to fly out of internal parts when the vehicle is in motion.

Can I Mix 10w30 and 5w30?

This is a question that has been asked for years. The answer is yes, you can mix 10w30 and 5w30 oils in your vehicle.

However, with so many different types of oil on the market, it is important to test each oil individually.

This is because some oils are designed for specific needs – either high performance or low-temperature protection – that will be different from others.

Conclusion 5w-30 vs 10w-30

The 5w30 is an oil that is designed to work in a higher temperature range, that is if you live in a place where the temperature drops a lot in winter and rises a lot in summer this oil suits you better, in turn, the 5w30 having a lower viscosity index makes gasoline consumption more efficient.

In the case of 10w30 being a more viscous oil will be better for engine parts, that is, a car says, with higher mileage and an older car will benefit more from oil like 10w30, only at the end of the day you have to follow the instructions that say your owner’s manual.
