Shopping guide
Taking care of your car’s engine is a simple task that you cannot neglect, and that begins with the proper lubrication of its mechanical parts. To do this, it is necessary to use an oil that adapts to the specific needs of each car, which provides greater performance on any terrain without causing wear to the series of gears. Here is a guide to buying the best 10w40 oil.
Composition
The composition of the product is one of the aspects that cannot be omitted from any comparison of 10w40 oils, due to its great level of importance in the operation of the engine. Therefore, the implementation of the wrong formula could seriously impair the performance of the machinery.
The important thing is that you know how to identify the right composition for the car. In this sense, you will find monograde motor oils that are of natural origin and have a single level of viscosity. For their part, multigrade lubricants are manufactured with chemical chains, capable of offering specific properties for each type of car.
In fact, this last type of composition allows maximum performance, both in the city and on long journeys, when going on vacation, because the formula adapts to low and high temperatures, for an effective cold start, without damaging the components. the motor.
Viscosity
The viscosity of the oil used in the car engine is of great importance for the correct operation and care of its internal parts, so we cannot select it at random, if we do not want to reduce the performance of the machinery. In addition, the issue of lubricant density is an aspect that, in most cases, influences how much the product costs.
Always keep in mind that the viscosity of this type of oil is determined by a numerical scale and a letter that, according to the nomenclature, corresponds to the type of starting offered. For example, oils designated with the acronym “W” indicate a cold start, which is the case with 10w40 lubricants. Therefore, you should check the specifications of the car, to get the right product for your needs.
In the market, you will find low and high density oils suitable for use in gasoline or diesel cars. These products, when incorporated into the engine, create a millimetric protective film between the gears, to prevent wear due to friction. In addition, they improve the performance of the machine in the most extreme conditions, without forcing the mechanical components.
Container
The container of the motor oil to acquire is an aspect that many people let go unnoticed, but which, in reality, is of great importance, since it is the structure that contains the lubricant and we will have to manipulate it to fill the engine. For this reason, it is not only necessary to obtain an economical product, but also an ergonomic and safe container.
In general, manufacturers of 10w40 oils use bottles made of robust and slightly flexible polymer, which will hardly break after an impact. In addition, these structures incorporate a top or side grip area with an ergonomic and non-slip format, designed in this way so that you can hold the container comfortably, both when pouring the product and when transporting it.
Likewise, these cans have been provided with a reduced mouth, to extract the oil moderately, while the screw cap and the seal in the form of a cap, preserve the good condition of the oil and prevent spills, in the event of an unexpected overturning at the handle the boat
Environmental care
The quality of the 10w40 oil purchased is of great importance, not only for good engine performance, but also for the care of the environment. Let us remember that, after starting the engine, a combustion process is generated in which all the residues that accumulate in the filter are incinerated, which immediately generates an emission of carbon monoxide, which pollutes the air we breathe.
In this sense, more and more brands are committed to the manufacture of synthetic type lubricants, since in this way they can create special formulas capable of enhancing the control of toxic emissions. Thus, it is possible to significantly reduce the high volumes of contamination common in conventional oils.
Frequently asked questions
Q1: How to use 10W40 oil?
To use 10W40 oil, you need to start by checking the level of lubricant in the engine tank, so you will have to remove the dipstick, clean it with absorbent paper, insert it again and remove it to know the exact measurement. Remember that the rod has a small mark, which is used as a reference for the measurement of the liquid.
Next, release the cap on the reservoir provided for the oil, carefully pour it in and wait at least five minutes. In this way, you will be able to repeat the initial procedure with the dipstick, to verify that the oil has reached the regulation measure for the correct operation of the engine.
It is important that, during the performance of this task, the machinery of the car is turned off and completely cold. Otherwise, the person could experience some kind of burn, due to poor handling of said areas of the car.
Q2: Every how many km is the 10w40 oil changed?
Changing the engine oil is a task that should be done periodically. In this way, you will be able to take care of the useful life of the mechanical parts and enhance effective performance. According to automotive experts, the time scheduled for the change could depend on the type of car, as well as the lubricant used.
For example, if you are one of the users who use mineral-type oil, you must change it after three thousand kilometers of travel. For their part, those who bet on oils with a synthetic formula, will be able to enjoy a maximum of six thousand kilometers of travel, before carrying out the oil change. Finally, if you pour 7100 full synthetic lubricant into the engine, you will have to change it after about 10,000 kilometers.
Q3: What base is 10w40 oil?
10w40 oil, both synthetic and semi-synthetic, has refined crude oil as its main base. However, the first of them is exposed to a laboratory process, in which the molecular level of the formula is changed through chemical processes.
In this way, a significant improvement is achieved in the results obtained when using it. For example, you will enjoy adequate temperature control and various levels of density, for better protection against wear of mechanical components.
For their part, semi-synthetic lubricants or also known as monogrades, add some mineral-type additives to the aforementioned petroleum base. Therefore, its formula only offers one level of viscosity.
Q4: What temperatures can 10w40 oil withstand?
With regard to the temperature supported by the semi-synthetic or multigrade 10w40 oil, it is important to note that it is suitable for climates that exceed 38°C and offers a smooth start from -30°C, while the synthetic or monograde models start from 10 °C onwards.
Q5: Which oil is better, 5w40 or 10w40?
Both 5w40 and 10w40 motor oil are high-quality products, but they have some significant differences, which could influence the performance of the engine in different scenarios.
For example, the 5w40 lubricant has a synthetic composition suitable for sports cars and, according to experts, its use is recommended for short trips, preferably within the city.
For its part, 10w40 oil is a semi-synthetic formula, which is convenient to be used in small cars, completing long road trips, without causing deterioration in the mechanical parts of the engine due to its high level of viscosity.
In fact, the density of both lubricants is one of the main differences between them, since, according to the 5w40 and 10w40 nomenclature, the first number indicates the viscosity; the letter, cold start; and the last number, the temperature. That is, the 5w40 is lighter than the 10w40.
Q6: Where is used 10w40 oil disposed of?
Once the engine oil change is complete, you must take care of the extracted lubricant, since it is a highly polluting substance, which we should not throw anywhere.
In this sense, it is important that you consult the official website of the brand used and investigate where the clean oil collection points are located. In this way, you will be able to help in the recycling process of this type of compound, taking said substance so that it receives the appropriate treatment and is regenerated, decontaminated or materialized.
Thus, this residual oil will be used to manufacture new products aimed at industrial plants or as part of the raw material necessary for asphalt, waterproof fabrics, among others.
