Difference Between 10w30 and 5w30

If we make a comparison between these two oils, we will see, both the 10w30 and 5w30 contain almost the same type of quality. But still, there are some differences that make them unique from each other.

Well, let’s see what the differences are and what the better option will be.

Differences of the Meanings

Both the oils contain almost the same type of features. But still, they have a different meaning. If we talk about the meaning of their names, then we can easily find some differences.

As we can see, there are two types of oils that we are talking about. The first one is 10w30 and the second one is 5w30 motor oil. We can find many differences in their names. The reason for the different names is the existence of viscosity.

The word W indicates the winter that the two oils stand for. And if we talk about the structure and thickness of both oils, then we will see that the 5w30 is thinner than the 10w30. And the numbers of these both oils describe it all.

That’s why you can say, there are some slight differences between these two oils. Otherwise, almost all the features of the two are the same. But for the meaning, it has a difference.

Comparison of their Lubrication

If we compare these two oils on the basis of better lubrication, then we would recommend you to choose the 5w30 motor oil. The reason is, it’s light and thin that’s why it can flow easily, and the engine can work in a smooth way.

Moreover, the 5w30 will be the suitable one because it works better for light-duty diesel, and also for petrol engines. Also, it works well if you use it for private vehicles.

And when it’s about motor oil, things should be considered carefully. Talking about 5w30 and 10w30 motor oils, we cannot recommend you to choose one. The two are good in their own way. But all you have to know is the right place to use.

If we examine the two then, we can see, both the 5w30 and 10w30 have the same SAE rating. And that’s why they will perform almost the same. Both have the digits 30. And it refers to the viscosity of at a high temperature.

Both oils have the same digits, and that’s why they will work the same way at the high temperature. But the first digits are different. 5 and 10 refers to the form of the oil. The 5w30 is lighter and thinner than the other one and thus it can easily move. And the 10w30 is thicker in a low temperature. So, the 5w30 can give you better service in cold weather.

Ideal Use Between These Two

Talking about the two motor oils, and the uses of those, the important thing that should be considered is the performance and how the thing is going to work. Both oils are good enough, but you need to choose the suitable one according to the situation.

Moreover, it’s important to know where you are going to use them. Weather is important at this point. And if you can figure out the thing then you can easily choose the perfect one and get the perfect result.

Though both engine oils are multi-graded, they work almost the same way. And as we know that the 5w30 is thinner than the 10w30, it can work effectively at a low temperature. So, the 5w30 can provide a better result in cold weather.

On the other side, 10w30 is better for hot temperatures. So, if there is hot weather around you, then you should choose the 10w30 one as it’s thicker motor oil than the other one.

So, in a sense, no matter whether you use 10w30 or 5w30 engine oil for your vehicle, you need to know the temperature and also where you are going to use it. And according to that point, you can choose the suitable one.


1. Should I use thicker oil in an old engine?

Yes, you should use thicker oil in an old engine because it can improve the quality of the engine and thus it gives much pressure on it. Moreover, the engine will demand the thicker oil, but not the less liquid one. The reason is, thicker oil can give the engine better protection when the engine is getting old.

2. What will be better among 10w30 and 5w30?

We cannot judge and select one between these two. Both oils are equally good for engines. They also work in the same way. The difference is that the 5w30 is the thinner one than the 10w30. So, this will be ideal for engines and you can use it in every season. On the other side, the 10w30 will be perfect for old engines.

Generally, almost all oils can mix together, and there is no problem in mixing these two. Though both the 5w30 and 10w30 have close viscosity, mixing these two won’t affect the engine. So, you can surely mix these two oils together if you want.

4. Is 5w30 good for old cars?

No, it’s not a good decision to choose 5w30 for old cars. As we know, it’s a thinner oil, and that’s why it can flow easily, it’s good for new and active engines, but for old ones, it will be a bad decision.

5. Will thicker oil manage my engine?

It will be tricky, but still thicker oil can manage your engine. Although you need to know first what the right oil would be for your engine. And after knowing that, you need to go further. Thicker oil won’t be appropriate for all types of engine. If you have an old engine then the thick oil can be helpful for you. But if it’s a new engine then you need to manage all the things carefully.

Final Verdict

To conclude, we must say, you can use 10w30 instead of 5w30, but you have to be very careful of some things that we have shared before.

Well, if you have 5w30, then you must use it for your new engine. But if you don’t have it then you can also use 10w30 motor oil. Though it works better for older engines, you can also use it as an alternative. All you need to do is to maintain the viscosity and then use.
