Can you mix 5W30 and 10W30 oil?

Can you mix 5W30 and 10W30 oil?

Can you mix 5W30 and 10W30? The simple answer is YES; you can mix the two oils; not just because they have the same weight, but because it is safe to mix two different engine oils. But if you’re stuck with no other choice, then you can go ahead to pour in that 10W30 into your engine that has been running 5W30.

Is it OK to mix different oil weights?

Generally, mixing oil weights is not recommended. But several viscosity grades are compatible and possible to mix, provided that they are under one motor oil brand. However, doing so will produce a new viscosity that is not the same as the original oil in the engine or the original oil to be added.

Can you mix different brands of motor oil?

“Yes. It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added.”

Is it OK to mix different oil grades?

In general, mixing oil weights is not recommended. However, several viscosity grades are compatible and possible to mix, provided that they are under one motor oil brand. But still, doing so will produce a new viscosity that is not the same as the original oil in the engine or the original oil to be added.

What happens when you mix two engine oil?

While the viscosity of the mixture may result in an engine oil somewhere in the SAE 40 range, where the “W” (winter viscosity) will end up is anyone’s guess. Again, different chemistry can be used to “build up” the viscosity of an engine oil, so mixing two from different viscosity ranges is not likely going to deliver the result that you desire.

Can different brands of synthetic motor oil be mixed?

Yes, all designated engine oil, synthetic, semi-synthetic or non-synthetic can be mixed with no harm. Even different viscosities can be mixed. This is a requirement all engine oil. The only problem comes from the fact that different types and brands have different additive packages.

Is it OK to mix motor oil?

Mixing Motor Oil. According to Mobil Oil, it should be fine to mix oils. This manufacturer states it would be unlikely anything bad would happen, such as a gel-forming from an interaction of the chemicals (a common fear), because the oils are compatible with each other.
