0w20 Vs 5w20 Oil: Perfect Answer !

You will often see 0w20 vs 5w20 in newer cars or any other small engine. With turbocharging and lubricating moving parts, they have become a prevalent fuel in today’s society.

Currently, a lot of people are interested in these two synthetic engine oils. Especially for those passionate about cars or any mechanic, this begs the question of which oil is best.

So to dig deeper, let’s analyze the difference for a better overview.

Difference Between 0w20 Vs 5w20

Difference Between 0w20 Vs 5w20

Both oils have a “w” in their name, making them ideal for cold climates. And now let’s go into detail about the differences between 0w20 and 5w20.

# Viscosity

Viscosity is the specific property of any oil, so the most significant difference between 0w20 and 5w20 is their viscosity.

Viscosity is an essential factor you need to consider when deciding to change your engine oil. It is a criterion that shows the thickness of the oil at different temperatures. At extreme temperatures, the thinner the oil, the better it is to deliver more practical functions. And typically, the ability to prevent friction will be better.

At low temperatures, 0w20 is very light, its thickness is zero, and 5w20 has 5. Overall, 5w20 is also common but still thicker than 0w20. If you only use the naked eye to see the flow, you will see that both are very thin when in cold temperatures. So when conditions like that, you use either one, will get high efficiency. However, at high temperatures, 0w20 has better performance.

# Subclass

At the engine oil level, we have mentioned viscosity. Currently, there are 11 different memory levels, and people use symbols to mark starting from 20 to 60 and from 0w to 25w. The manufacturer’s division of these grades allows you to evaluate each oil’s performance at different temperature conditions.

As for the two types, they are multi-level to work in both hot and cool conditions. However, 0w20 is ideal for cold areas around 20 degrees, while 5w20 is suitable for more relaxed environments.

These values ​​represent less oil concentration under low-temperature conditions. It can be that this feature makes 0w20 and 5w20 the ideal solution for you to move freely in the engine and thereby help prevent and reduce friction.

Generally, 0w20 has a lower grade, so at maximum cold conditions. In similar situations, we see the 5w20 as a higher level. And both can operate at high temperatures but only moderately.

# Performance

Many people have asked us: in terms of performance, which oil is better. The answer is that they have similar performance.

After going through the tests, we found both oils to work the same. From a technical perspective, 0w20 has a slight advantage when operating at too cold temperatures. In this situation, the oil will flow freely, so you can quickly start your engine.

In the case of high temperatures, both also work but with limitations. So 0w20 vs. 5w20 is not a good choice for hot weather conditions in some areas.

# Fuel economy

Besides considering the characteristics and parameters, the level of fuel economy is also of great concern for any customer. It is a criterion many people consider before making a selection decision.

Even when it comes to fuel economy, there’s not much of a difference between the two. Although both have low fuel consumption, if you calculate the details, 0w20 seems to have won.

With a fantastic foundation, 0w20 and 5w20 will translate into a smooth and easy flow to ensure efficient engine operation. At the same time, it also helps to keep the engine parts free of problems. Thereby this enables you to save significant maintenance costs and save more fuel.

# Price

In general, the price depends on the manufacturer, so that the price will have a significant difference in each region. However, in general terms, 0w20 is a bit more expensive than 5w20. Because of the best performance that 0w20 provides in low-temperature conditions, it will be more expensive.

Compared to the prices of many other single-grade motor oils, they are more expensive. Although it is more costly, we believe you will get more value for what you spend. That will show off in the functions of the oil.

Frequently Asked Questions

Can I replace 0W20 with 5W30?

Although the properties and functions of these two oils are similar and there is not much of a difference, we think it’s best to respect the manufacturer’s instructions because this will be safe and avoid problems for your engine.
Many people think that 5w20 is an excellent combination of two common and high-grade synthetic oils, replacing 0w20. But if your motor is 0w20, then you should prioritize following the recommendation.

What if I use the wrong engine oil?

When you use the wrong engine oil level, the conditions you may encounter are leaking oil, reducing engine life, making the engine operate, making noise, etc… In addition, the problem of starting the source and the consequence, even more severe, is burnt oil.

When experiencing an oil leak, consider how much it costs to fix an oil leak because the manufacturer will not provide a warranty for the engine. The reason is that you used the wrong type of oil specified, resulting in engine failure, and you are responsible for it.

How long does 0w20 oil last?

If you ever refer to some documents, you will know that 0w20 is a synthetic oil appreciated for its long service life. Especially in low-temperature conditions, you will find 0w20 to be the ideal choice for long-term use.


0w20 and 5w20 are two common oils used in synthetic multistage engines. The above information is our sharing about the difference between the two oils and related questions. Both work well in cold conditions, so it’s best to rely on the manufacturer’s instructions to use the right oil for your engine.
