The 0W-20 Oil Guide (Meaning, Uses, 6 FAQs)

November 24, 2021

0W-20 oil is an increasingly popular motor oil for the typical passenger car. It’s good for engine protection and helps with sludge buildup, fuel consumption, and fuel economy. 

But should you be using 0W-20 oil?
If not, what can you use instead of 0W-20 oil?

In this article, we’ll take a close-up look at 0W-20 oil. We’ll also cover some other related queries, including what it’s used for, whether it is bad for your car and if it is only available as synthetic motor oil.

Let’s get started!

What Does 0W-20 Oil Mean?

0W-20 is a winter viscosity multigrade SAE oil that provides excellent cold start performance and lubricates your engine parts in colder temperatures.

0W-20 oil is very thin in cold temperature climates, so it flows very easily without causing a lot of friction. At a normal operating temperature, it also flows very smoothly and lubricates critical engine parts. 

Additionally, this multigrade oil also performs adequately at relatively high engine temperature settings. While it may not give a thicker engine protection barrier, like 0W-30 or 5W-40 oil, it is still considered a decent choice for seasonal climates.

So what are some applications of 0W-20 multigrade oil? 

What Is 0W-20 Oil Used For?

0W 20 oil is commonly used for modern petrol and gasoline engine cars. It is the perfect choice for everyday use, especially in colder climates.

It is usually not recommended for two-wheelers and aviation vehicles since these operate at extremely high temperatures. 

Apart from fast lubrication (which helps avoid engine wear), 0W 20 oil also helps prevent engine deposits, sludge formation, and corrosion. 

Note: Always refer to your manufacturer’s manual for the right kind of oil for your car. Using the wrong oil viscosity can be detrimental to your engine life and affect your car’s fuel efficiency.

Keeping that in mind, what are some other things you need to know about 0W-20 oil? 

6 FAQs About 0W-20 Oil

Let’s take a look at some frequently asked questions about 0W-20 oil and their answers. 

1. Is 0W-20 Oil Bad For My Car?

It depends. 

Is it the recommended oil viscosity for your car? 
Does your car run smoothly on this viscosity grade? 

No oil viscosity is inherently bad for your car, it just depends on how appropriate it is.

0W-20 is a popular oil viscosity grade, especially during colder winters and in low operating temperature conditions. It prevents viscosity breakdown and engine wear and offers better fuel efficiency. 

With the right engine and environmental conditions, 0W-20 is certainly not bad for your car. The best way to determine this is to consult your mechanic and vehicle manufacturer manual for the recommended oil viscosity of your petrol or diesel engine. 

Just remember that even with the right oil grade, wrong oil change routines can still damage your engine life and lead to engine deposits and sludge. 

2. Is 0W-20 Oil Good For High-Mileage?

0W-20 engine oil offers decent mileage and fuel economy for older engines. If you drive a lot in cold temperature climates and practice routine maintenance combined with normal driving habits, it should be a good fit for your car. 

Fully synthetic motor oil or semi synthetic motor oil will give you a longer oil change interval on average, with better fuel efficiency. 0W 20 synthetic oil will also perform better in preventing oil breakdown when compared to conventional motor oil. 

Suppose your car has any special requirements for engine oil (like certain additives, or mileage limits for a diesel engine or gasoline engine). In that case, you can also look for a specially formulated high-mileage oil.

3. Is 0W-20 Always Available As Synthetic Oil?

To make a winter viscosity oil like 0W-20, you need high-quality synthetic base oil and additives. The synthetic base oil prevents viscosity breakdown and ensures smooth lubrication in low temperature conditions. As such, 0W-20 does not make for a reliable conventional oil.

Synthetic oil is more refined and predictable in its quality, engine performance, and fuel economy. Most times, 0W 20 oil has a partial or fully synthetic base oil and additives in it. 

As a result, it’s either available as a semi synthetic engine oil or as fully synthetic engine oil. 

0W 20 synthetic oil will certainly perform far better than similar grade conventional oil in preventing sludge buildup, oil breakdown, and engine wear. 

4. How Is 0W-20 Oil Different From Other Oils?

It depends on the oil in comparison. 

0W-20 engine oil is quite versatile with its operating temperature range. It provides excellent cold temperature performance, along with a decent hot-temperature performance. 

Compared to, say, 0W-30 or 5W-20 oil, you won’t notice much of a difference. 0W-20 will act slightly better in a low temperature climate, but there won’t be a noticeable difference in engine efficiency. 

But compared to higher viscosity oil grades like 10W-30 or 20W-50, 0W-20 is a much thinner oil. It will provide superior low temperature performance and flow smoothly through the engine parts with almost zero friction or resistance. 

On the other hand, 20W-50 is a high-temperature motor oil that’s more resistant to oil breakdown. It is not suitable for everyday vehicles and typically used for heavy-duty diesel and gasoline engine models.

5. What Can I Use Instead Of 0W-20 Oil?

Generally, 0W-30, 5W-20, and 5W-30 oil grades behave very similarly to 0W-20 oil. So you may want to look into those if 0W-20 oil isn’t available. 

These are a thinner oil, similar to 0W-20, and flow smoothly throughout the engine. They also offer similar benefits, including improved engine performance, fuel efficiency, better fuel economy, and preventing sludge buildup.

However, if you decide to shift to a different oil grade, consult your car mechanic beforehand.

It’s always advised that you stick to your recommended motor oil grade. Using the wrong oil can result in improper engine protection.  

6. What Are Some Popular 0W-20 Oil Brands? 

When buying engine oil, it is best to stick to reputed manufacturers that use quality ingredients. Irrespective of whether you’re using conventional oil or 0w 20 synthetic oil, high-quality oil has several benefits.  

Some popular brands are:

Remember, a good car oil can boost your car’s engine efficiency, and help lower fuel consumption while offering a better fuel economy. 

Closing Thoughts

0W-20 is an excellent winter viscosity grade oil that provides superior engine performance and a smooth oil flow. Its thinner oil structure makes it ideal for cold starts and below-freezing temperatures. In the right engine, it can do wonders for the car’s critical engine parts and performance.

Most importantly, remember to get routine maintenance and regular oil change intervals to give your car some TLC.
