Best 5w30 Synthetic Oil 2023 | Ultimate Buying Guide

Now that we have seen which are the best brands of 5w30 oil, below we are going to make a complete overview so that you can have all the answers on this type of product.

What does 5w30 oil mean?

The letter W stands for the English word winter, meaning winter. The figures before the W are those relating to the viscosity that the oil has at low temperatures, at -18 ° C. The lower these figures, the better the viscosity of the oil at low temperatures, an oil therefore suitable for the winter period. Consider that if the viscosity is low, it means that the oil remains fluid even when it is very cold, so as to favor a correct start of the engine, without any effort, so as to guarantee the circulation of the oil and impeccable lubrication of all its components. In this case, the viscosity in winter is 5, which is really excellent.

The digits after the W instead indicate the oil viscosity at high temperatures, 100 ° C. In this case, the viscosity is 30 at maximum effort. We must admit that motor oils with a higher viscosity in the summer are available, but 30 is an excellent value for the temperatures reached here in Italy.

Viscosity is certainly not the only important feature when choosing engine oil for your car. If you are looking for a good 5w30 engine oil , we, therefore, recommend that you also consider:

• Composition. There are synthetic oils and mineral oils on the market. The choice depends on the engine of your car. In fact, some engines can only work with synthetic oils. Others, however, with synthetic oils risk being damaged and it is therefore absolutely necessary to choose mineral oils. Obviously, it is important to check these elements in the registration document of your car.
• API and ACEA. These classifications allow us to understand the number of additives present in them, the ash content, and other similar characteristics. These are also elements to be taken into consideration depending on your engine, to always check in the car booklet.
• Car manufacturer approval. Car manufacturers put their engines through rigorous tests before putting cars on the market. Thanks to these tests, they are able to indicate which oils are best suited to respond correctly to the specific needs of that car. Precisely for this reason, it is good to check that the oil you are about to buy has been approved directly by the manufacturer.

From the considerations we have just had the opportunity to make, it is obvious that 5w30 motor oil should not actually be considered as an oil suitable exclusively for the winter period. It is in fact a multigrade oil, which works well at both low and high temperatures, both in winter and in summer. In short, it is the ideal oil to be used throughout the year.

5w30 engine oil, most important features

The 5w30 engine oil allows obtaining a really excellent viscosity in the case of starting the engine at -30 ° C. It also allows you to get an equally excellent fluidity at -35 ° C . As for the kinematic viscosity, it ranges from a minimum of 9.3 and 12.5 mm2 / s. As far as the dynamic viscosity is concerned, we are in the order of 2.9 mPas.

Precisely for these characteristics, the 5w30 motor oil is able to be pumped flawlessly by the lubrication system, without any kind of difficulty even in the long run. In this way, all the elements that make up the power supply system are always kept clean. In this way, it is also possible to favor a correct cooling of all the components and to be able to avoid excessive fuel consumption.

Are there any negative characteristics that 5w30 motor oil possesses? In our opinion, this engine oil has one and only negative characteristic. When gaps are created between the friction pairs, this oil fails to fill them perfectly, thus making it possible to incur oil leaks.

5w30 or 5w40 motor oil?

As we have just seen, the benefits of 5w30 motor oil are innumerable. It is also true, however, that this is certainly not the only multigrade engine oil available on the market. In fact, there is also 5w40 engine oil. Wouldn't it be preferable to use this second product?

5w40 engine oil has very similar characteristics to 5w30 engine oil. Also in this case, in fact, the viscosity is excellent at -30 ° C and the fluidity at -35 ° C. The discourse is different as regards the kinematic and dynamic viscosity. In the case of the 5w40 engine oil, in fact, the kinematic viscosity ranges from 12.5 to 16.3 mm2 / s while the dynamic viscosity is equal to 3.5 mPas.

With this oil it is undoubtedly possible to eliminate the risk of oil leaks at the root , which instead are possible with 5w30 motor oil. This is because it produces a much thicker film , which is why it is also extremely resistant. The film fills without any difficulty the empty spaces that are created, so as to be able to work even with particularly important loads. This detail is extremely important for high-powered sports cars. However, it is also true that the engine could suffer in the long run.

If yours is a city car, avoid it unless you live in an area where the outside temperatures are very high . In this case the situation changes, because this is an oil that allows the engine to work at its best even when the conditions are extreme. But, let's face it, here in Italy it is rather difficult for conditions of this type to be reached. In short, you don't have to go and drive your car in the desert!
