Today in this blog post, we’ll go through the detailed comparison between 5w30 vs 10w30.
As you know, the engine is the essential part of every Vehicle, and without its normal functioning, a vehicle couldn’t perform at its maximum potential. An engine requires time to time maintenance and lubrication for an average level of functioning. It also takes in the air for combustion apart from gasoline.
So there are chances that your engine can get contaminated with dirt and debris during this intake. Most of this dirt cannot be clear during the maintenance; therefore, it leads to sludge formation, which can further raise the issue of engine failure. Here the role of a high-quality engine oil comes in.
A multigrade engine oil such as 5w30 and 10w30 not only serves as the lubricating fluid but also filters out the contaminants. It can increase the Engine longevity by lubricating the hundreds of moving parts and by reducing the friction.
Nowadays, engine oils come in 5w30, 10w30, and other different variants depending on the viscosity factor. But both of these ratings are known as multigrade engine oil due to their wide temperature range.
What do 5w30 and 10w30 Numbers Mean?
Since the engine oil differs in terms of their oil characteristics, therefore Society of Automotive Engineers (SAE) has introduced a numerical code for their differentiation. Temperature directly influence the Viscosity of engine oil; for this reason, companies have started formulating multigrade oil. Multigrade oils offer comprehensive protection to your engine even in different temperature ranges.
- In 5w30, the first digit 5 refers to cold Viscosity, the oil thickness of the oil at low temperatures
- The W stands for winter
- The last two digits, like 30 in 10w30, refer to the thickness at high temperature.
If you’ve chosen oil with a much higher viscosity (maximum thickness), it can cause some problems. These problems can be related to an engine’s different components, and if unchecked, it can even lead to engine failure.
5w30, a Lower Viscosity Oil is an Excellent Choice for Both Cold Weathers and Warmer Temperature Due to its wide Working Temperature Range.
Similarly, if you go with a too much thinner oil, it will result in metal contact within the engine. With this subsequent increase in the drag, the components’ connection will lead to wear and tear of different engine parts.
What is Viscosity? And How is it a Crucial Factor?
Firstly, let’s understand the concept of Viscosity in engine oil, and then we’ll move on to its importance.
When we talk about Viscosity, we’re referring to this engine oil’s ability that how easily it can pour. Thin-oil due to lower Viscosity, can pour and move more efficiently in colder conditions. But, thicker oil, which has comparatively more Viscosity, doesn’t flow easily as thinner oil does.
To make it more transparent, we can say 5 or 10 is the grade that represents the rate through which any engine oil can flow. Here Lesser rate refers to more ease of flow. On the other hand, these multigrade vary their Viscosity during warmer conditions.
Why is it essential to look for the Viscosity before choosing any engine oil?
These numerical codes are assigned by the Society of Automotive Engineers (SAE) to differentiate the engine oil based on the viscosity factor. Motor oil is considered the lifeline for any engine and it determines how long it is supposed to last. Tech-Savvy understands very well that engine oil not only serves as the lubricating oil, but it also has many more to do with your engine.
Let’s deeply analyze the role of Viscosity with some examples.
For instance, you’ve poured 10w30 oil within your engine, and you’re living in a region where the average temperature is -25. Since 10w30 oil has a slower pouring capability due to its higher viscosity factor; therefore, it will pour very slowly. Due to this reason, it is expected that your engine performance will get affected.
While on the other hand, if you had opted to use 5w30 instead of 10w30, there would be no effect on the engine’s performance. Similarly, engine oil should have higher Viscosity during Summer for optimal performance.

5w30 vs. 10W30 – How both differ from each other?
5w30 is a multigrade engine oil with a viscosity grade of 5 and 30 at colder and warmer temperatures, respectively.
Key specification of 5w30
It meets the requirements and standards set by FORD, Mercedes Benz, API SN, Porsche, ACEA grade, and Volkswagen. Hence, it has the approval of all these Car Brands, and you can also use it if you own a similar car.
Its Major Benefits
Its unique characteristics are as following:
- In terms of protection, it provides above-average lubrication to the components of your car. As it creates a layer above the moving parts of the engine, which reduces the chances of deterioration of any component.
- The life of your engine will get extended as it also provides a shield against rust. Components of the engine will keep on working interruptedly years after years.
- This engine oil is designed to reduce oil consumption, so a small amount of oil can be sufficient for lubrication.
- Since it is multigrade oil, which works equally in both extreme warmer and colder conditions, therefore, due to its good thermal capability, you will not feel any difference in its performance regardless of any state.
Satisfactory performance is guaranteed whether you’re living in Africa or Canada.
The oil is specifically made to suit both harshest conditions and provides better lubrication to your engine. In warmer conditions, it can work quite well even at 35 degrees centigrade. Similarly, in colder conditions, it Viscosity varies according to state, but performance remains optimal.
It can be used in different vehicles but better suits the automotive gasoline engines, light-duty diesel engines, and light-duty petrol engines. Due to lower Viscosity, it flows quickly in extreme lower temperature.
10w30 is multigrade engine oil, which is fully capable of withstanding higher temperatures without affecting the engine.
Key specification of 10w30
American Petroleum Institute has introduced API SN, which is an engine oil category. This category has set individual specifications for engine oil. According to this, engine oil should have the capacity the protect the engine piston from any fuel combustion. Also, it should have better sludge control and must be seal compatible. Fortunately, 10w30 meets all of these requirements of API SN.
Not only API SN, but it is also approved by European Automobile Manufacturers Association.
Its Major Benefits
10w30 comes with many unique benefits, which are jotted down below:
- Even with the fluctuation of temperature, it keeps the Viscosity in balance.
- The lifespan of your engine can be significantly increased because it also protects the engine from getting rusted.
- Your engine will remain cool because it works to decrease the wear and tear of engine components. Also, for lubrication, it creates a layer over different parts for non-stop operation.
- Your engine will work smoothly without creating any noise.
This multigrade oil can be used for vehicles that carry heavy loads or heavy luggage. In terms of engine type, you can use it for petrol or diesel engine. If you are an inhabitant of a region where the temperature remains higher throughout the year, you should go with 10w30.
When to Use 5w30 vs 10w30 – Ideal Temperature
If you’re living in the Northeastern United States or Canada, then 5w30 is a brilliant choice for sure. Similarly, if you’re a resident of a region where the temperate hits 35 Celsius in Summers, then 5w30 can be your first choice of engine oil; its wide temperature range can enable your car to work optimally regardless of any temperature.
10w30 is also manufactured to meet any temperature requirement and provide excellent protection plus performance simultaneously. Although it has less temperature window as compare to 5w30, it comes with different and unique advantages. To sum up, this multigrade oil works best between -18 degrees Celsius and 30 degrees Celsius.
5w30 vs 10w30 – Which oil is better for your car?
10w30 is comparatively thicker and provide better sealing capabilities. Due to these characteristics, it is useful if you use it for older engines. When a machine gets older, most of its clearances become widen and consequently require a thicker oil for better lubrication.
5w30 put less drag on bearings and other moving parts of an engine, resulting in less wear. The most important thing about 5w30 is its versatility in terms of the different temperature ranges. It can withstand both kinds of harshest conditions, and you don’t need to worry about any subject condition. For this reason, I’ll suggest you go with 5w30 for standard usage, but in case of heavy loads or luggage, 10w30 is a better option.
If you’re residing at a place where the temperature remains low most of the time, 5w30 performs much better and at startups. On the opposite side, if you live where the temperature remains continuously higher, 10w30 can be a perfect choice as it allows rapid movement. In simple words, light oil ideal for cold climate, whereas thicker oil is best for constant warmer conditions.
