Is It OK To Mix Different Brands Of Engine Oil?

Does it matter if you put different oil in your car?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important.

Use only what the owner’s manual specifies.

Using the wrong oil can lead to reduced lubrication and shorter engine life.

If the manual says to use synthetic oil, do so..

What happens if you mix two engine oils?

Mixing different oils will not improve the performance or efficiency of the engine in any way. The additives in synthetic oil may have limited or no effect at all when mixed with a regular engine oil. … Now, as far as different grades are concerned, mixing between them isn’t something that will damage your engine either.

What happens if I use 5w40 instead of 5w30?

Takeaway. If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.

What happens if I mix 5w20 and 5w30?

You can mix a 5W20 with a 5W30 oil with minimal amount of issues provided it the same manufacturer and the same API classification. … I would suggest just getting the oil changed.

Is 0w20 better than 5w30?

It readily means that the 0 oil will flow well and better at a cold temperature more than 5W-30 oils even while maintaining the same viscosity. The 0W-20 is said to be the best oil in the market because it helps to reduce environment hassle on waste oil disposal.

Can you mix 5w30 with 10w30?

Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W30 and 10W30 are essentially the same at operating temperature. It is only for cold weather starting that the performance will be different.

Can I use 10w40 instead of 5w30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

What happens if I put 5w20 instead of 0w20?

The 0 oil will flow better at cold temperatures than the 5 oil. Both oils will have the same viscosity at operating temperature. Using one or the other should cause no issues. … Read the owners manual but seriously look at the OEM oil specs and 5w20 is going to be a superior oil than a 0w20.

What happens if you mix oil?

Answer. In general, oils should be compatible with each other. It is not likely that you would form gel by mixing the two oils. However, we would not recommend mixing oils as a general practice because oils are complex mixtures of additives and base oils that can be destabilized.

What happens if you use 10w30 instead of 5w30?

10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

What happens if you mix 5w20 and 10w30?

If you mean adding 10w30 to an engine full of 5w20, you’d create your own mixture of 7w24 or something like that. Your engine will be fine. … Can 5W-40 oil harm the engine if the manual says use 10W-40?

Can you mix synthetic and regular oil?

Yes, you can safely mix synthetic and conventional oil. … In the end, conventional and synthetic oils are completely compatible. However while you can safely mix synthetic and conventional oils, you’re diluting the performance of the synthetic oil.

What happens if I use 0w20 instead of 5w30?

0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. … I would suggest using a viscosity for your engine that your manufacturer recommends. You can find that recommendation in your owner’s manual.
