Can You Mix 0W-20 And 5W-30

Yes, you can mix 0W-20 and 5W-30 oils. However, it is not recommended as it can lead to decreased performance and increased wear on your engine.

While it is generally recommended to use the same viscosity grade of oil in your vehicle, in certain situations, it is possible to mix different viscosities such as 0W-20 and 5W-30. However, it is important to note that mixing oils can alter the overall viscosity and performance characteristics of the oil.

When you mix oils with different viscosities, you end up with a blend that has properties somewhere between the two original oils. For example, mixing 0W-20 and 5W-30 oils would result in a blend that is slightly thicker than 0W-20 but slightly thinner than 5W-30.

If you find yourself in a situation where you need to mix oils due to unavailability or other reasons, it’s generally recommended to stay within the same viscosity range and try to keep the difference minimal. In the case of 0W-20 and 5W-30, the viscosity difference is significant, so it is not an ideal blend.

It’s important to consult your vehicle’s owner’s manual or speak with a qualified mechanic to determine the recommended oil viscosity for your specific engine. Following the manufacturer’s guidelines will help ensure optimal performance and protection for your engine.

What Happens If You Use 5W-30 Instead of 0W20

If you’ve ever wondered what would happen if you used 5W-30 oil instead of 0W20, wonder no more! We’re here to give you the scoop on this commonly asked question. To start, it’s important to know that 5W-30 and 0W20 are both motor oils.

They are designed to lubricate your engine and keep it running smoothly. However, there are some key differences between the two oils. 5W-30 is a thicker oil than 0W20.

This means that it will provide better protection for your engine, but it may also lead to increased fuel consumption. In addition, 5W-30 can be used in a wider range of temperatures than 0W20. This makes it a good choice for use in colder climates.

On the other hand, 0W20 is a thinner oil than 5W-30. This means that it won’t protect your engine as well, but it will improve fuel economy. Additionally, 0W20 is less likely to cause leaks than 5W-30 oil.

Can You Mix 0W-20 And 5W-30


Will 0W20 Hurt a 5W30 Engine?

The answer to this question is no, 0W20 will not hurt a 5w30 engine. The reason for this is because the two oils have different properties and are intended for use in different types of engines. 0W20 oil is a synthetic oil that is designed for use in newer, high-performance engines.

It has a lower viscosity than 5w30 oil and is therefore thinner and less likely to cause wear on engine parts.

Can You Mix 5W And 0W?

Yes, you can mix 5W and 0W motor oils. However, it is not recommended as it could potentially damage your engine. The two oils have different viscosities, meaning they flow at different rates.

Mixing the two could result in an oil that does not flow properly and does not protect your engine as intended.

What Happens If You Put 5W30 Instead of 0W-20?

If you put 5w30 oil into a car that requires 0W-20, the oil will be too thick and won’t flow properly. This can lead to engine damage as well as decreased fuel economy.

Will It Hurt Your Engine to Add 2 Different Oil Types?

It’s not recommended to mix oil types as it can cause sludge build-up and deposit formation, which can lead to decreased engine performance and increased wear. The best way to avoid this is to use the same type of oil for top-ups and changes.


If your car requires 0W-20 oil and you can only find 5W-30, is it okay to use the 5W-30 oil? The answer is yes, you can mix 0W-20 and 5W-30 oils without any problems. The two oils have very similar viscosities, so they will mix together just fine.

However, keep in mind that using a higher viscosity oil may put more strain on your engine, so it’s best to use the recommended oil if possible.
