As much as we would like to stress that combining motor oils is not a good idea, we cannot deny the fact that it is safe to do so, especially if they are all from the same manufacturer. However, you may want to inquire as to whether or not you may top off a 5W20 engine with 5W30.

Maybe you are interested:

At low temperatures, 5W30 and 5W20 will operate identically and flow uniformly. That’s encouraging, isn’t it? If the two oils are from the same company and belong to the same API class, they will blend better.

Can You Mix 5w30 And 5w20 Oil?

Is the basic response as stated in the preamble paragraphs above, YES? Mixing 5W30 with 5W20 is very safe and ok to do.. If you’re using 5W20 oil to top off a 5W30 engine, you’re not causing any harm to the engine’s essential components at all. There is a possibility that the oils have different additives, which is why they have varied weights. The additives in the two oils won’t mix, so it doesn’t matter; your car’s engine won’t suffer any harm as a result.

“Why do you want to blend oils?” Yes, I’d like to know why you’d like to combine different oils. No matter how much oil your engine is running low on or how much fresh oil you’d want to try, you’ll find it here at AutoAnything.com. Regardless of the cause for your journey, you should drain the new (irregular) oil once you reach at your location and refill it with your regular oil after you’ve there. Regardless of whether you drain the new oil and replace it with your old one (when you get it), your car will continue to run well. Those who want to totally change the oil in their car’s engine should do their homework on the possible drawbacks of not using the oil advised by the car manufacturer.

What Actually Happens When You Mix 5W30 with 5W20?

There will be no major events. It is improbable that the oils would combine to form a single oil, thus they will remain separate and continue to flow. Both oils would flow uniformly to the top ends at low temperatures because they both have the same viscosity for cold weather. Also, as previously said, it’s ideal if the two oils you’re about to mix are from the same brand. This suggests that there won’t be much of a performance difference, which could lead to improved results. Due to incompatible additives in the oils, your engine won’t be guaranteed to run better if you mix them together.

If you live in a state where the temperature is always high, 5W30 will perform better. As a result, some drivers use thicker oils in the summer and return to thinner oils in the fall and winter, respectively. It is still safe to practice this if that is what you choose to do.

Conclusion

“Can 5w30 and 5w20 oil be mixed?” is an excellent question to ask. Yes, and it’s preferable to stick with oils from the same manufacturer. To make a long story short, we think your car requires synthetic oils. Motor engines gain greatly from the use of synthetic fuels. The fact that motor oils deteriorate over time is also worth noting. In addition to following these guidelines, you’ll be less likely to suffer engine damage, which might cost you a lot of money.
