Is it possible to mix car oils of different brands?

The short answer is yes, it is possible to mix car oils from different brands. However, it is important to note that each brand of oil has its own formula and specific additives. By mixing two different brands, you run the risk that the additives will not be compatible and could affect engine performance. Also, some brands may have particular specifications and recommendations for their oil, so mixing them together could void the vehicle's warranty.

If you decide to mix oils from different brands, it is advisable to do so only in emergencies and on a temporary basis. In these cases, it is important to ensure that the oils are of the same viscosity grade and meet the vehicle manufacturer's specifications. In addition, it is advisable to carry out an oil change as soon as possible to avoid long-term problems.

Consequences of mixing two brands of motor oil in a car

Mixing two brands of motor oil in a car can have various consequences. First of all, the additives of each brand may not be compatible with each other, which could affect the lubrication and protection of the engine. This could result in increased wear on internal engine parts and a reduction in engine life.


Also, each brand of oil has its own specific formulation and properties. By mixing two different brands, there is a risk that these properties will be altered, which could affect engine performance and efficiency. It's also important to note that some brands of oil have special additives to clean and protect the engine, so mixing two different brands could compromise these benefits.


In summary, mixing two brands of motor oil in a car can have negative consequences for the engine and its performance. It is advisable to follow the vehicle manufacturer's recommendations and use only one type of engine oil to ensure optimum performance.

Consequences of mixing two different oils for cooking or frying

In the culinary field, doubts also arise about the mixture of two different oils for cooking or frying. The answer to this question depends on the type of oil being used.

In general, mixing two different cooking oils has no negative consequences. However, it is important to note that each type of oil has its own smoke point, which is the temperature at which the oil begins to break down and release smoke. By mixing two oils with different smoke points, you run the risk of burning the oil more quickly and generating toxic substances.

On the other hand, mixing two types of frying oil can have more serious consequences. Some oils, such as olive oil, have a lower smoke point than other oils, such as sunflower oil. If these two types of oil are mixed, the olive oil could burn before reaching its smoking point, which could generate toxic substances and affect the flavor of the food.


In conclusion, it is advisable to use only one type of oil for frying and take into account the smoking point of each oil to avoid health problems and maintain the flavor of the food.


Myths and truths related to the use of oil

There are many myths and popular beliefs related to the use of oil. Next, we will demystify some of them:

Is it true that motor oil should be changed every 3,000 miles?

Not necessarily. How often motor oil should be changed depends on the type of oil used and the vehicle manufacturer's recommendations. Today many synthetic oils can last up to 7,500 miles or more before needing a change. It is important to follow the manufacturer's recommendations to ensure proper engine maintenance.

Is it true that olive oil is the best cooking oil?

While olive oil is known for its flavor and health benefits, it is not necessarily the best oil for all culinary preparations. Olive oil has a strong flavor that may not be suitable for certain dishes. Also, its smoke point is lower than other oils, which means it is not ideal for high-temperature frying. For frying, it is recommended to use oils with a higher smoke point, such as sunflower oil or canola oil.

Is it harmful to reuse cooking oil several times?

Reusing cooking oil several times can be harmful to health. Every time oil is heated, it breaks down and toxic substances are generated. These substances can be harmful to the body if consumed in excess. Additionally, used oil can contain food residue and bacteria, increasing the risk of contamination and disease. It is advisable to dispose of used oil properly and use fresh oil for each preparation.
