Engine Oil Change: Know All About This Procedure


Lubricant is a necessary replacement item. This means that after a particular time or if the vehicle runs a specific mileage, the car’s engine oil must be changed. This product is losing its properties throughout its numerous work cycles.

Therefore, an engine oil change is essential for the car. Despite being a simple procedure, it can catch many drivers off guard and result in immense injury. Shell technical lubricant manager César Cerbam explains that the oil protects the engine parts internally, reducing friction between moving parts (which are metallic), prevents rust formation, a buildup of dirt and aids in cooling.

Old oil cannot provide to fulfil all these functions. If you are a lamb and do not pay attention to the propellant lubrication, you will have to deal with the consequences of sloppiness. And there are many: sludge formation, power loss, and even the engine melting.

If your car is still under warranty, be sure to follow your car’s overhaul plan, which already includes an engine oil change. But if your warranty is already gone, it’s time to know how to handle it yourself. So follow these tips and make sure your vehicle mechanics have a long life.

When to Change?


The first thing is to know when the engine oil change should be done, information that is in your car manual. Let’s use Chevrolet Onix (best selling in the country) as an example. It is read in the model manual:

With the engine warm, change the oil every 5,000 km or six months, whichever comes first, if the vehicle is driven under “Heavy-duty conditions.”

When 5,000 km have passed since the last replacement, change the engine oil. If you haven’t reached 5,000 km yet, but it’s been six months, it’s time to change too. At the same time, the oil filter should be replaced as it accumulates debris that may contaminate the new lubricant.

It is worth mentioning: we are using the example of Onix, which, in this case, predicts the mileage of 5,000 km. But this does not apply to all models. The recommendation to change the engine oil may occur at a lower distance (every 4,000 km, for example) or higher mileage (every 10,000 km, citing analogous case). To find out the correct time, consult your car manual.

Is My Use Severe or Mild?

When severe car use occurs, the oil should be changed at shorter intervals. And this type of use is common, especially in large cities. Ipiranga Lubricants Director Miguel Lacerda explains that this is the condition of vehicles that face heavy traffic in large cities, with traffic moving or short distances. “Dirt roads are also considered to be severe use because they provide greater oil contamination,” adds Lacerda.

So make no mistake about using it lightly. Henrique Pereira, a member of the Otto Engine Technical Commission of the Brazilian Society of Mobility Engineers (SAE), points out that one of the most severe conditions is that of the underused vehicle. “For example, who goes out to take the child back and forth; go out again, shop and come back; Then she looks for her son again,” he details.

Light use would be for transport fleet vehicles, which run on roads and over long distances. For them, the frequency is higher, as in the case of Onix:

If the vehicle is not driven in severe conditions, change the oil every 10,000 km or 12 months, whichever comes first.

How to Choose the Lubricant

You need to know three things to choose the right engine oil for your car: the API index, the SAE index, and, in some cases, the oil type. This information is also in the manual, as in the case of Onix:

Specified oil Dexos one or equivalent API SN quality, ILSAC GF5 or higher, and viscosity SAE 5W30.

Dexos 1 is a specific lubricating oil recommended by Chevrolet. This means that Onix has undergone many tests with this fluid, and they were made for each other. But it doesn’t hurt if you choose another oil from the same API and SAE, as long as it’s from a trusted brand.

In other manuals, there may still be the name of the type of oil, which is mineral, semi-synthetic, or synthetic. If not, it is because that lubricant is only available on a basis, as in the case of Onix. The 5W30 is always synthetic.

Lastly, here’s a tip: Once you choose the lubricating oil, be true to it. Avoid changing a brand, type, or quality. Mixing different oils can lead to unexpected and dangerous engine reactions.

Car oil: Better than the Others?

Generally, the vehicle manufacturer indicates in its owner’s manual a lubricant oil of its own brand. Who produces the fluid, however, is not the automaker, but some oil company. This is a trade agreement, which governs the supply of
