Car owners want to know if they can mix 0w20 oil and 5w30 oil. This article will answer the question for you if you have the same one. You should stay and read.

You can mix 0w20 and 5w30 oil, but it’s not recommended.

Experts do not encourage or recommend mixing different oils. They said that if you can avoid that activity, then do so.

Many car owners reported that there were no severe damages to their vehicle and that they had already been doing the mixing.

Some car owners say doing such mixing is harmful to the engine. You are here to learn more about this.

We will discuss if you can mix 0w20 oil and 5w30 oil, and what happens if you mix them. So, without further ado, let’s start.


Is It Possible To Mix 0w20 and 5w30 Oil?

It is possible to mix 0w20 and 5w30 oil. It does not necessarily mean that you should. If you can, you should not mix 0w20 oil and 5w30 oil.

They seem to have no significant problem with their vehicle. There can be a small problem with a reduced fuel economy, but that is why other car owners started doing it.

You should get your oil changed if you get home because you will have to mix both oils. The rule of thumb is that you should always follow the instructions in the owner’s manual.

Is It Possible To Add 0w20 to 5w30 Oil?

There is a way to add 0w20 oil to 5w30 oil. You should remember that this is not a good idea. Adding or mixing two oils is not something you should do.

Some people say that you might consider not doing this if your vehicle is new. If the fuel economy is affected, you might have to top up your oil with a different one.

Again, if you don’t have any other choice, you can top it up. When you have the right oil for your vehicle, you can always do an oil change.

Is It Possible To Add 5w30 to 0w20 Oil?

Yes, but it doesn’t mean that you should. You should use the recommended oil for your vehicle. Refer to your owner’s manual for the recommended oil for your vehicle again.

Possible Downsides

It is okay, that’s right. If we talk about a complete engine failure and significant damage to your vehicle, you don’t have to worry about that at all.

Your vehicle’s warranty can be voided if you have a vehicle that is under warranty.

What Happens When You Mix 0w20 and 5w30 Oil?

There isn’t anything that would happen if you mix 0w20 oil and 5w30 oil. There are no problems with your engine.

Many people say that mixing 0w20 oil and 5w30 oil will not bring good results and that it will not bring bad results.

If you want to benefit from the oil, it’s best to stick with just one oil.

What Is the Difference Between These Two?

The viscosity of the two oils is different. Some oils flow well in low temperatures and oils flow better at higher temperatures.

Protection to engine parts is provided by highly viscous oils that are thinner with high temperatures.

They maintain their consistency and drag through the engine, which reduces the performance of the engine.

In high temperatures, low-viscosity oils get thinner and do not provide enough protection to engine parts, even though they are thin enough to flow through the engine.

In the long run, using the wrong engine oil in extreme temperatures could cause engine damage.

Viscosity Difference

To understand the right oil for you, it’s important to know that winter-grade oils are thinner than oils suited for higher temperatures.

Considering the number included in the oil names, 0W20 has a lower winter number than 5W30, indicating that it’s better suited for use in winter.

5W30 oil has a higher figure for its suitability for high temperatures than 0W20 oil, which indicates that the oil is better suited for high temperatures.

The ability of both fuels to adapt to both warm and cold climates will not be affected by the difference in viscosity.

Both oils can operate effectively in both warm and cold temperatures. 0W20 and 5W30 adapt better to cold climates, while 0W20 and 5W30 do not.

Fuel consumption

Lower-viscosity oils do not affect the fuel economy of the car, because they have higher efficiency. 0W20 is about 10 to 20% more efficient than 5W30 because of its low viscosity.

Despite the low fuel consumption of 0W20 oil, the cost of the oil is higher than the cost of 5W30 oil, which gives approximately the same costs.



If you mix 0w20 oil and 5w30 oil, you can do it. The rule of thumb is to stick with only one oil, that’s why it’s not recommended by experts.

While mixing 0w20 oil and 5w30 oil will not give your vehicle terrible results, it won’t give your vehicle good results.
