When should I have my car’s engine oil changed?

The process of making oils has been known to humans for millennia.

Still, the first people who picked olives could not have imagined that there would one day be vegetable oils, animal oils, oils derived from petroleum, and synthetic oils and that one of the uses for these oils would be to ensure that motor vehicles function correctly.

When should I have my car's engine oil changed?

However, technological progress proceeds unabatedly, perhaps too unabatedly for you, to whom thousands of thinkers and inventors have devoted their time and effort to provide you with a good car, to end up forgetting to change the motor oil in your vehicle.

Check Let’s the manual to see when and how the car’s engine oil should be changed.

What exactly is the function of engine oil?

Because changing the Oil is equally as crucial as adequately refueling the vehicle, it is not something that should be done whenever we remember (perhaps one year after purchasing the car or perhaps ten years later).

This article will make it abundantly clear what the appropriate tempos are and the kind of Oil that works best for us.

But before we get into that, let me give you a quick rundown on the significance of motor oil: The primary function of the Oil is to act as a lubricant for the engine, ensuring that everything operates as it should.

In addition to these benefits, it protects the engine from wear and tear, cleans out impurities, and keeps it from overheating.

The machine can be protected from illness by performing regular maintenance. What else do you need from me? It provides more benefits to you than you provide to it.

The oil schedule has been used for the majority of its history.

Let’s look at the recommended oil change intervals based on mileage and total driving time, which is the most common and convenient method.

There are two distinct checks that mechanics will perform on a brand-new vehicle.

Some people suggest doing it once a year or every 15,000 kilometers, while others say you should do it once every two years or every 30,000 kilometers.

Is one of these choices superior to the others in any way? Before making a purchase, it is in your best interest to inquire about the vehicle’s technical specifications at the dealership.

This is because manufacturers of automobiles typically research when the optimal time for an operation is.

There are brand-new automobiles.

When it comes to used cars, even if we have the vehicle’s history, there is no way for us to know for sure what challenges it has faced because we can never know what the future holds. As a result, it is necessary to perform an oil change before beginning to drive.

After that, the Oil should be changed every year or every 10,000 kilometers, whichever comes first.

This disparity in mileage is not without significance: In the past, cars were lubricated with either mineral or semi-synthetic oils.

These oils have nothing in common with modern motor oils, which are entirely synthetic and engineered to provide superior protection and longevity.

What different kinds of motor oil are there to choose from?

Not all oils serve the same purpose or have the same characteristics.

One can categorize them in various ways, including according to the production standards, the viscosity standards, or the approval standards.

1. Based on the results of their production

Mineral, synthetic, and semi-synthetic oils are the three types of oils that can currently be purchased from retail outlets.

Mineral oil

It is manufactured using a refined petroleum base as its starting material.

It is recommended for engines that have already reached a high mileage and are pretty worn.

Mineral oil’s change periods are significantly shorter than those of synthetic oils.

Synthetic Oil

The crude petroleum that has been refined and distilled is then subjected to a transformation process for it to acquire specific characteristics and a higher level of quality.

They protect the engine and keep their properties for a more extended period because they have low volatility and can withstand higher temperatures.

For demanding engines, synthetic is the material of choice.

Partially synthetic Oil

It is a combination of mineral and synthetic oils, as the strong tagline indicates.

Their excellent performance makes them the product of choice for customers, but compared to synthetics, they do not compare favorably.

2. Based on the thickness of their consistency

An oil’s viscosity is considered one of its most essential characteristics. We differentiate between multigrade and monograde materials based on the grade of the material.

This characteristic determines how much resistance the oil molecules offer to flow when it is being measured.

It is essential for adequate protection of the engine that the viscosity be high when the temperature is high but that it flows nicely when the temperature is low.

The viscosity index provides information about how the density of a substance changes as a direct result of temperature changes.

Multigrade Oil

A highly refined oil with a high viscosity range that shifts in response to changes in temperature, allowing it to perform admirably in any given set of circumstances.

It is appropriate for automobiles that will be driven in regions that experience significant variations in temperature.

Monograde Oil

Because it has a low viscosity index, it can only be used in regions where the temperature is relatively consistent over time.

3. According to approval standards

The American Society of Automotive Engineers (SAE) and the American Petroleum Institute (API) are the organizations that establish the specific vocabulary for engine oils.


The Society of Automotive Engineers has established 11 types of Oil, ranging from 0W to 60, where the viscosity is related to the engine’s temperature.

In SAE terminology, the first number describes the substance’s density when cold and at low temperatures.

The second number indicates the Oil’s viscosity when it has been heated.


The American Petroleum Institute is the organization that was responsible for developing the API mark.

The first letter identifies the kind of engine that this component is designed to work with (S, in the case of specific lubricants for gasoline engines, and C, to particular oils for diesel engines, although they are only valid for diesel engines of heavy machinery, trucks, buses, etc., and not for light vehicles).

In the same way that the alphabet is arranged in ascending order, the quality level of the lubricant is denoted by the second letter of the alphabet.

Currently, the following types of gasoline engines are available: SH, SJ, SL, SM, and SN. And these designations apply to diesel engines: CH-4, CI-4, CJ-4, and CK-4.

According to the RACE, the most common type of motor oil used in gasoline-powered vehicles in Spain is multigrade 0W-20, while the most common type of motor oil used in diesel-powered vehicles is 5W-30.

What exactly are oil sensors, though?

Oil sensors have been a significant step in improving the accuracy of determining when a vehicle’s Oil should be changed.

The timing described earlier already works for us (as a result, we are prepared for any mishaps).

Still, the new oil sensor functions improve overall fuel efficiency and safeguard the properties of the engine oil in a wide variety of different situations.

The majority of today’s engine oil management systems are designed to provide the driver with information in real-time to cut down on operational expenses.

We can more precisely adapt to the oil change and reduce our overall fuel consumption thanks to this method.

A warning light will immediately illuminate when the driver’s vehicle detects that the oil level is dangerously low.

When should I have my car's engine oil changed?

How exactly is it that the Oil in the engine should be changed?

We have saved the question that first-time drivers typically pose to themselves until last: Am I able to adjust on my own? Of course, you can. In addition to that, carrying it out is a straightforward process.

You will only require gloves, a funnel, and a motor canister, typically 5 liters in capacity.

Going to a garage guarantees the quality of the service (it will cost you between 50 and 100 $), but if we are sure how to do it, we can get it without any problems.

Going to a garage guarantees the quality of the service.

The following are the steps that need to be followed:

To change the Oil properly, a more complicated method involves emptying the crankcase; however, if we want to use this method, it is best to delegate the task to someone trained.

The oil filter is recommended to be replaced each time the Oil is changed.

We must be aware that the engine may sustain significant damage.

It is not a problem if we go a few more kilometers or stay a few more weeks, but we can’t go much further over the limit than that. The Oil deteriorates, and mechanical failures begin to take place.

It is doubtful that your insurance company or the manufacturer provided their warranty, still covers you, and will pay for the repair.

We need to determine from the car’s manufacturer what Oil the vehicle uses.

It is never a good idea to mix engine oils because doing so results in creating a new mixture with different characteristics, which may have implications for the maintenance of the engine.

In any event, when faced with an emergency, we ought to select an oil with the same viscosity as the one we carry.
