Is it OK to mix different grades of engine oil?
The short answer is yes, it is generally safe to mix different grades of engine oil. However, this should be done only occasionally and as a temporary solution until your next regularly scheduled maintenance check. It’s important to note that mixing should only be done if the oil you use is within the weight (or viscosity) range recommended in your owner’s manual.
Effects Of Mixing Different Viscosities Of Oil
Mixing different viscosities of oil can potentially affect the overall viscosity in your engine. This can lead to reduced lubrication and increased wear on engine components. Therefore, it is generally not recommended to drive with the wrong viscosity of oil in your engine, as it may cause long-term damage.
However, if you have no other option and need to top off your oil, mixing 5W20 and 10W30 oils of the same brand and type may be acceptable. Keep in mind that this should only be a temporary solution, and you should consider getting an oil change as soon as possible.
Expert Opinions
There are several opinions on this topic from experts and automotive enthusiasts. Some state that mixing oils won’t hurt anything, while others recommend avoiding it altogether. Here are a few perspectives from different sources:
- Bob is the Oil Guy: Mixing different oils won’t cause any harm.
- SVTPerformance.com: Mixing oils is fine, but avoid overfilling and try to change the oil as soon as possible.
- Ford-Trucks.com: Mixing oils will result in slightly thicker oil, but it will be fine.
It’s important to note that these opinions are based on personal experiences and may not apply to all scenarios. It’s always a good idea to consult your vehicle’s owner’s manual or seek advice from a professional mechanic.

Can You Use 10w30 In A 5w20 Car?
Yes, it is generally safe to mix different weights of engine oil in a car as long as the oil used matches the weight recommended in the owner’s manual. Mixing occasionally for topping off oil should not damage the engine.
However, it is not recommended to drive with the wrong viscosity of oil in the engine for long periods, as it can lead to increased wear and reduced lubrication.
Is It Ok To Mix 5w And 10w Oil?
Yes, it is okay to mix different grades of engine oil occasionally, as long as you use the weight or viscosity recommended in your owner’s manual. However, mixing different viscosities of oil can affect overall viscosity and potentially lead to reduced lubrication and increased wear on engine components.
It is generally not recommended to drive with the wrong viscosity oil in your engine to avoid long-term damage.
Is It Ok To Mix Different Grades Of Engine Oil?
Yes, it is generally okay to mix different grades of engine oil occasionally. If you need to top off your oil between scheduled maintenance checks, using the same viscosity (or weight) of oil recommended in your owner’s manual is important.
However, regularly mixing different viscosities can affect overall viscosity, potentially causing reduced lubrication and increased wear on engine components. It’s best to follow the manufacturer’s recommendations to avoid long-term damage.
What Happens If You Put 30 Oil Instead Of 20?
Mixing different oil weights, such as putting 30 weight oil instead of 20, is generally alright for occasional use. It shouldn’t damage your engine as long as the oil used matches the weight recommended in your owner’s manual. However, it’s not recommended for long-term use as it can potentially lead to reduced lubrication and increased wear on engine components.
Can Mixing Different Grades Of Engine Oil Damage Your Engine?
Mixing different grades of engine oil occasionally should not cause damage to your engine. If you need to top off your oil, as long as you use the weight or viscosity recommended in your owner’s manual, mixing is safe.
Conclusion
In conclusion, while it is generally safe to mix 5W20 and 10W30 oils on a temporary basis, it is not recommended for long-term use. Mixing different viscosities of oil can affect lubrication and increase engine wear. It’s best to follow the recommendations in your owner’s manual and seek professional advice if you have any concerns. Ultimately, it’s important to prioritize regular oil changes and use the proper oil for your vehicle to ensure optimal performance and longevity.
