In the world of automotive, there are many myths and misconceptions when it comes to engine oil. One common question that often pops up is whether you can mix different oil viscosities, specifically 5W30 and 0W20. In this article, we will dive into this topic and provide you with the answers you need.
The Short Answer: Yes, You Can Mix Them
Contrary to popular belief, it is perfectly safe to mix engine oils of different viscosities. Whether they are synthetic, semi-synthetic, or non-synthetic, there will be no harm in mixing them together. Even if the oils come from different brands, as long as they have the same viscosity, you can mix them with confidence.
Some car enthusiasts argue that mixing different types or brands of oil can cause compatibility issues and potential damage to your engine. However, this is a misconception. The key factor to consider is viscosity. As long as the viscosities are the same, you won’t encounter any difficulties.
Understanding Oil Viscosity
Before we delve deeper into the topic, let’s have a brief overview of oil viscosity. Viscosity refers to the oil’s resistance to flow. It is measured using two numbers, such as 5W30 or 0W20. The first number indicates the oil’s viscosity at cold temperatures, while the second number represents its viscosity at operating temperatures.
In the case of 5W30, the “5W” indicates that the oil has the viscosity of 5 at low temperatures, allowing it to flow easily during cold starts. The “30” refers to its viscosity at operating temperatures, which means it is thicker than 0W20 oil. On the other hand, 0W20 has better cold-start performance but might be less durable at higher temperatures.

The Potential Effects of Mixing Different Viscosities
Mixing different viscosities, such as 5W30 and 0W20, can lead to slight changes in performance. The most noticeable effect could be a slight reduction in fuel economy. This is because the thicker oil, 5W30, may cause slightly more internal friction, resulting in a small decrease in efficiency.
However, it’s important to note that the impact on fuel economy is usually minimal and barely noticeable in everyday driving. Modern engine designs and advancements in oil technology have reduced the significance of this effect. So, if you find yourself needing to top up your oil and you only have different viscosities available, go ahead and mix them. It won’t cause any major issues or harm to your engine.
Frequently Asked Questions On Can You Mix 5w30 And 0w20
Is It Ok To Mix 5w And 0w Oil?
Yes, it is safe to mix 5W and 0W engine oils. All designated engine oils, including synthetic, semi-synthetic, or non-synthetic, can be mixed without any harm. Even different viscosities can be mixed. There may be a slightly reduced fuel economy in the short term, but it is not a cause for concern.
Can I Mix 5w-30 With 0w 30?
Yes, you can mix 5W-30 with 0W-30 engine oil. Mixing different viscosity grades of the same brand motor oil is compatible. However, it is always advisable to not mix motor oil brands. Mixing oils of different viscosities is not recommended.
Can You Mix 5w-20 And 0w-20 Full Synthetic?
Yes, you can mix 5W-20 and 0W-20 full synthetic oils without any harm. Different viscosities can be safely mixed. However, it may result in slightly reduced fuel economy in the short term. Always remember to use the same brand of oil whenever possible.
Can I Mix 5w-20 And 30?
Yes, you can mix 5W-20 and 30 motor oils without any harm. Different brands and viscosities can be safely mixed together. However, keep in mind that there may be a slight reduction in fuel economy in the short term.
Faq 1: Can You Mix 5w30 And 0w20 Motor Oil?
Answer: Yes, you can safely mix 5W30 and 0W20 motor oil. Both synthetic and non-synthetic oils of different viscosities can be mixed without any harm.
Conclusion
In conclusion, you can safely mix 5W30 and 0W20 oils without experiencing any negative consequences. As long as the oils have the same viscosity, you have nothing to worry about. Mixing different engine oil brands is generally discouraged, but different viscosity grades within the same brand are compatible.
So, the next time you find yourself in a situation where you need to mix oil viscosities, go ahead and do it without any hesitation. Your engine will remain in good shape, and the small trade-off in fuel economy will be negligible.
