Welcome to our article where we will address one of the most common concerns for those who use olive oil in their cooking and for those who need to keep their engine in good condition. In this article, we will answer the most frequently asked questions about how to identify if an olive oil or motor oil is in bad condition and how to take the necessary measures to solve it.

How to identify if an olive oil is in poor condition?

Olive oil is an essential ingredient in many kitchens and it is important to ensure that it is in good condition before using it. Here are some signs of deterioration to watch out for:

color changes

One of the first signs that olive oil is bad is a change in its color. A good quality, fresh olive oil should be golden or light green in color. If you notice that the oil has turned a dark yellow or even brown color, it is probably bad and unsafe to consume.

Rancid smell

Another indicator that olive oil is in poor condition is its smell. A fresh olive oil should have a pleasant and fruity aroma. However, if you notice a rancid, vinegary, or even musty odor, the oil is likely bad and should be thrown away.

Effects of heat and cold

Olive oil can also deteriorate due to the effects of heat and cold. If the oil has been exposed to extreme temperatures for a long period of time, it may have lost its properties and is in poor condition. If you notice that the oil has solidified or become too liquid, this is an indication that it has been affected by heat or cold and should not be used.

How to identify if a motor oil is in bad condition?

For those who own a vehicle, it is essential to keep the motor oil in good condition to ensure optimum performance of the car. Here are some tips to identify if the motor oil is in bad condition:

eye check

An easy way to check if your motor oil is bad is to perform a visual check. If the oil is dark and opaque in color, it is likely contaminated with dirt particles and engine debris. Also, if you notice that the oil looks thick or viscous, it is an indication that it has lost its lubricating properties and should be changed.

Indicators on the car dashboard

Most modern vehicles are equipped with a monitoring system that displays the condition of the engine oil on the dashboard of the car. If the gauge shows a low oil level or an oil warning light on, it is important to check the condition of the oil immediately. These indicators are a sign that the motor oil may be bad or that the vehicle needs an oil change.

Unusual noises and vibrations

If you notice unusual noises or vibrations while driving, this may be an indication that your motor oil is bad. Poor engine oil can cause excessive friction between engine parts, which can lead to abnormal noise and vibration. If you experience these symptoms, it is advisable to check the condition of the motor oil and take the necessary measures.

Frequently Asked Questions (FAQs)

1. What is the shelf life of olive oil?

The shelf life of olive oil depends on several factors, such as the quality of the oil, storage conditions, and exposure to heat and light. In general, good quality olive oil can last up to two years if properly stored in a cool, dark place. However, it is important to be aware of the signs of deterioration mentioned above and discard the oil if it shows any of these signs.

2. How often should I change the motor oil in my vehicle?

How often you should change your vehicle's motor oil depends on the type of oil used and the manufacturer's recommendations. In general, it is recommended to change motor oil every 5.000 to 7.500 kilometers or every six months, whichever comes first. However, it is important to consult your vehicle's owner's manual for specific recommendations.

3. Can I mix different brands of motor oil?

Mixing different brands of motor oil is not recommended, as each brand may have different formulations and additives. Mixing oils from different brands can affect the quality and performance of the oil, which can have a negative impact on your vehicle's engine. It is best to use the same type and brand of oil recommended by your vehicle manufacturer.


In summary, it is important to watch for signs of deterioration in both olive oil and motor oil. Changes in color, rancid smell and effects of heat or cold are indicators that the oil is in poor condition and should not be used. For motor oil, it is advisable to perform visual checks, pay attention to the indicators on the car's dashboard and be alert for unusual noises and vibrations. By following these guidelines, you will be able to identify if the oil is in poor condition and take the necessary steps to fix it.
