For a car engine to perform smoothly, survive a long time, and be protected from damage, it is critical to use the right motor oil. The viscosity temperature properties are an important selection consideration.

According to the international standard for lubricant viscosity, or SAE, these qualities are referred to. No matter how good the oil is, this indicator only tells you how viscous it is at a given temperature. All-season, winter, and summer oils are characterized based on this.

Features of 0w20 engine oil

0W20 vs 5W30 Oil

SAE 0w20 engine oils are multi-grade products. In order to run at temperatures between 5°F and +68°F, the oil must have at least 5.6 mm2/s viscosity at an engine operating temperature of 100°C (212°F).

It is displayed by the first digit (winter index) and the last digit (20 (summer index) on the oil recipient that shows the temperature range.

The 0w20 oil recommended by Japanese vehicle makers is widely utilized in the automobile sector. While this oil type is rarely recommended by producers in the European market, at the same time,

This is because of the internal combustion engine’s design features and the most common operating modes. In addition, the degree of engine wear is a significant element and should be taken into consideration first when choosing an engine oil.

Because of this, the use of 0w20 engine oil is advised for engines with less than a 30% degree of wear.

Characteristics of 5w30 engine oil

For this reason, many lubricant makers aim to increase production of engine oils with a minimum SAE 5w30 designation, rather than the more limited use of 0w20 motor oils. This type of motor oil is more popular with engines and sells more frequently, but at a lower cost.

Considering that 5w30 oil may be used in any season due to its operating temperature range of 35 °C (representing the 5 winter) to + 25 °C (representing the 30 summer), this means that it can be used year-round. When the temperature of the engine is 100 °C, the viscosity of the 5w30 oil is 9. 5 mm2/s.

The usage of the 5w30 mark is advised for internal combustion engines with a wider degree of wear in the range of 0% to 60% of the engine’s resource when this kind is recommended by the automobile manufacturer.

What do 0w20 and 5w30 engine oils have in common?

Following a discussion of their features and a comparison of these two types of engine oils, the following general aspects may be observed:

Differences between 0w20 and 5w30 engine oils

There are several important variations between these oils, despite the fact that they share some features.

When it is best to use 0w20 and 5w30 motor oils?

0w20 and 5w30 engine oils are, in reality, in the same manufacturer’s line and have sparked a lot of debate among enthusiasts regarding which is better.

Once all of the information has been weighed, we can say with confidence that using the oil the manufacturer suggests is a must starting as soon as the vehicle is purchased.

This may be simply done by checking your car’s manual, where you’ll find a greater choice of options to pick from based on your engine mileage.

Increase the viscosity of 0w20 oil to 30 when driving for an extended period of time, especially under harsh operating circumstances. An increase in oil consumption, which is likely to be eliminated after the replacement, is a primary factor to consider when making this decision

If your automobile has an annual mileage of more than 9, 000 miles and the oil is changed at least twice a year, you should use 0w20 in the winter and 5w30 in the summer because the viscosity will dramatically decrease in hot weather.

You should also avoid using 0w20 and 5w30 oils at the same time.

Though the oil’s properties are an important consideration, it is important to remember that they are not the only factors that should be taken into account when selecting an oil to lubricate your car’s engine.


Finally, if you’re unsure what kind of oil to use, the car’s owner’s handbook is an excellent place to start. There’s some wonderful advise in there, but only after considering the big picture of things like engine mileage and how you drive your car..
