Motor oils are available in a wide range of brands, viscosities, and costs. The viscosity of all of these motor oils is critical. Knowledge about the right oil for your vehicle’s engine is essential for routine maintenance.
What’s the difference between 0w20 and 5w40?
In addition to your engine’s design, the climate and weather can have a significant impact on the type of oil you use. We’ll go through the distinctions between these two oils in this article.

About 0w20 and 5w40 engine oils
What the numbers and letters imply is crucial to our understanding of these motor oils. Oil viscosity is indicated by the letters ‘W’ and the corresponding digits (or thickness).
The oil’s cold viscosity is indicated by the number immediately preceding the word W. While the number after the word W indicates the viscosity of your engine at typical operating temperature.
Even though 0w20 is more popular, 5w40 is designed to guard against sludge accumulation, deposits, and other engine damage.
Some people prefer 5w40 synthetic oil since it is less expensive and more readily available than 0w20 synthetic oil. Since it is increasingly being employed in both new and preexisting automobiles, 0w20 is gaining in popularity. People are drawn to it because of its efficacy, which speaks for itself.
The suggested viscosity can be found in your owner’s handbook, but we’ll go over the most significant aspects of each type of oil nonetheless.
Features of 0w20 engine oil
Numerous car models now use engine oil with a viscosity rating of just 0w20. The following is a list of some of its features.
- 0w20 meets the API SN requirements
- It is approved by many vehicle manufacturers as a recommended oil
- Reduces friction between moving components
- Excellent cold startup
- Good anti-wear and anti-corrosion properties
- Capacity to improve fuel efficiency
- Highly recommended for use in cold environments
- Excellent lubricating ability
- Provides outstanding protection to the engine.
- Long time between oil changes
Features of 5w40 engine oil
The 5w40 oil has the following characteristics:
- It ensures the engine is protected from deposit buildup
- Covers a wide range of temperatures
- It provides wear protection
- Outstanding lubricating properties
- This oil also meets all the API SN requirements
- Recommended for a variety of vehicles with various engine types
- Prevent the engines from corroding
- Ensures good cold starting and quick circulation in freezing temperatures
What do 0w20 and 5w40 engine oils have in common?
The following are some common advantages shared by 0w20 and 5w40:
- They are both considered as multigrade oil, which means they can perform well at high and low temperatures
- They provide adequate lubrication for moving parts, resulting in improved engine performance
- 0w20 and 5w40 are both high-quality synthetic oils that ensure protection against deposits
Differences in engine oil viscosity between 0w20 and 5w40
For chilly climates, the 0w20’s temperature range is between 40 °C and 20 °C, making it suited for moderate summers. 5w40 oil can be used all year round because its working temperature ranges from 35°C to 35°C. 5w40 oil has a wider operating temperature range than 0w20 oil.
Viscosity
High-quality synthetic oils with low viscosities like 0w20 and 5w40 are made to be used in cold climates. As the temperature increases, the viscosity of 0w20 oil increases from zero to twenty. The viscosity is 5 at low temperatures and 40 at high temperatures, as indicated by the 5 in 5w40.
The lower viscosity of 0W20 than 5W40 means that it will flow more easily through the engine in cold weather. Because of its increased viscosity, 5w40 motor oil performs better in hotter weather.
Fuel economy
5w40 is less efficient than 0w20 in terms of fuel use. Because lubricant flows more smoothly at lower viscosities, the higher the fuel efficiency. The 0w20 oil is claimed to be more fuel efficient than the 5w40 because it is thinner and less viscous.
High mileage
Using 0w20 engine oil in conjunction with routine maintenance and normal driving behavior is sufficient for drivers who log a lot of miles on their vehicles. Some mechanics recommend using 5w40 oil. Higher-mileage engines frequently employ 5w40 oil. To preserve worn engine bearings, heavier base oil generates a thicker oil coating.
Keep engine clean
Protecting your car is the primary goal of both 0W20 and 5W40 lubricants. In order to maintain the engine clean, it reduces the amount of high temperature deposits on the cylinder walls. As a result, both two oils have the same ability to keep your engine clean.
When is it best to use 0w20 and 5w40 motor oils?
When it comes to chilly conditions, 0w20 is the best option for individuals who live in frigid regions.
If you reside in an area where temperatures frequently fall below freezing, 0W20 is the ideal choice. For cold-weather start-up, 0w20 gives somewhat less wear than 10w20. Because of its thicker viscosity, 5w40 is better suited to hot temperatures.
Conclusion
Your engine’s performance depends on the oil you use, so don’t skimp. It is important to use the correct quality of oil for your car in order to get the most out of your vehicle’s performance and save money on gas.
There was a clear preference for 0w20 when these two oils were compared. Because it is more efficient and better suited to cold areas, 0w20 is significantly more sought after. It is, however, more expensive and less common. In terms of temperature and performance, 5w40 has a wider temperature range and is also effective.
You can choose the best choice for your situation based on the facts supplied. Always consult your owner’s handbook to determine the correct type of oil to use in your vehicle. Use both options if they appear on the list.
