When it comes to choosing the right motor oil for your vehicle, it is essential to ensure that you are using the recommended viscosity specified by the manufacturer. However, there may be instances where you need to mix different viscosities of oil, such as 0W 20 and 5W 30. In this article, we will explore whether it is safe to mix these two oil viscosities.
What does the viscosity rating mean?
The viscosity rating of an oil refers to its resistance to flow at different temperatures. The numbers before the “W” represent the oil’s viscosity at low temperatures, while the numbers after the “W” represent its viscosity at high temperatures. For example, 0W 20 oil has a thinner consistency at low temperatures compared to 5W 30 oil.
Manufacturer’s Recommendation
It is generally not recommended to mix different viscosity oils than what is specified by the manufacturer for your engine. Manufacturers determine the appropriate viscosity based on the engine’s design and tolerances. Using the wrong viscosity oil can affect the performance and longevity of your engine.

Opinions from Experts
There are differing opinions on whether it is safe to mix different viscosities of oil. Some experts claim that mixing oils of different viscosities, including synthetic, semi-synthetic, or non-synthetic, poses no harm to the engine. They argue that even different viscosity oils can be mixed without causing immediate issues, apart from potentially slightly reduced fuel economy.
However, it is important to note that the consensus among manufacturers and automotive forums is to follow the recommended viscosity and avoid mixing oils. Mixing oils of different viscosities, even if they have the same viscosity grade, may lead to potential compatibility issues and impact the oil’s ability to provide adequate lubrication.
Frequently Asked Questions For Can You Mix 0w 20 And 5w 30
What Happens If You Put 5w-30 In A 0w20 Car?
Mixing a different viscosity oil, such as 5W-30 in a 0W-20 car, is generally not recommended by the manufacturer. However, it may not cause significant issues in the short term, except for slightly reduced fuel economy. It is best to stick to the oil specified by the manufacturer for optimal performance and to avoid potential long-term damage to your engine.
Is 0w 20 The Same As 5w-30?
No, 0W 20 and 5W-30 are not the same. It’s important to use the viscosity oil specified by the manufacturer for your engine to ensure optimal performance. Mixing different viscosities or oil types is generally not recommended.
Can You Switch Between 0w 20 And 5w 20?
Yes, you can switch between 0W-20 and 5W-20 without any issues. Different viscosities can be mixed and it won’t cause harm to your engine. However, keep in mind that using a different viscosity oil than what is specified by the manufacturer may result in slightly reduced fuel economy.
Can I Mix 0w20 And 5w40?
Mixing 0W20 and 5W40 oils is generally not recommended. It is best to use the viscosity oil specified by the manufacturer for your engine to ensure optimal performance. Mixing different viscosities can lead to slightly reduced fuel economy. It is advised to stick to the recommended oil for your engine.
– Can You Mix Different Viscosities Of Engine Oil?
Yes, all designated engine oil, synthetic, semi-synthetic, or non-synthetic can be mixed with no harm. Even different viscosities can be mixed.
Conclusion
In conclusion, while some sources claim that mixing 0W 20 and 5W 30 oils may not cause immediate harm to the engine, it is always advised to follow the manufacturer’s recommended viscosity. Mixing different viscosities of oil can potentially lead to compatibility issues and affect the engine’s performance in the long run. For optimal engine health, consult your vehicle’s manual or reach out to a certified mechanic for guidance on the appropriate motor oil viscosity.
