Can you combine motor oil?

Even if two different brands of oil have the same viscosity, you still should not be mixing them together. Technically, using a grade of oil that’s recommended by your car manufacturer is correct. However, if you combine two different brands of motor oil, you could be at risk of damage.

What happens if you put 10W20 instead of 10W30?

Bottom line, no you will not hurt the car by putting in either 10W20 or 10W30.

What happens when you mix motor oil weights?

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.”

Can you mix 10W30 and 10/40 oil?

Mixing 10W30 with 10W40 Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle.

Can I top up oil with different oil?

You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car’s manual are your reference for using the right oil.

What happens if you mix different brands of motor oil?

No. Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. You may give up enhanced performance if you switch from synthetic or high mileage to conventional oil. MYTH: When motor oil becomes dark, that means it’s time to change it.

Does 10W20 oil exist?

HD Fleet Oil SAE 10W20.

Is there a 10W 20 motor oil?

MOTOR OIL EXTRA SAE 10W/20 is suitable for vehicles, motorbikes and stationary systems that are operated with monograde motor oils. EXTRA SAE 10W/20 monograde oils can also be used in specific gears and hydraulic systems for which monograde motor oils are required.

Can you mix oils of the same weight?

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.

What happens if you put 10W40 instead of 10W30?

The basic fact that “40” is greater than “30” tells you that. If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.

Can you mix 5W30 and 10W30 oil?

Yes, you can mix 5w30 and 10w30 oil. But only when both of them are at operating temperature. At operating temperature 5w30 and 10w30 are the same and can be mixed. But at low temperatures, they show opposite reactions.

What happens if you put 10W40 in a 10W oil pump?

Now that you put 10W40 in it. When cold, the oil is at SAE 10W characteristic which is within the capacity of your oil pump to handle, however, when it finally reaches operating temperature, the oil will then have a characteristic of an SAE 40 oil which is thicker. That is when your oil pump will suffer.

What happens when you mix two different engine oils?

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. Another uncertainty is the shear stability of a mixture of two different weights.

Can I mix 10W-30 and 15w-50 viscosity?

As the additive formula used to construct each viscosity (10W-30 and 15W-50 in this case) can utilize different chemistry, there simply is no way to project how well the mixture will actually work and whether the longevity of the oil mix will be affected.
