Mercedes oil change is similar to blood for our body. It is vital. It is a crucial element that allows your car be able to travel and to last. The selection of engine oil is not easy, since every oil is made to be able to handle a specific engine. Imagine for a second a negative blood transfusion within your body? It is possible to imagine that this could cause harm… It’s the same in the case of an oil that is not properly selected that your engine might not enjoy it. Don’t worry we’re here to assist you make an informed decision, mercedes oil change.


Motor oil allows for the moving of the vehicle with no breaking. It’s used for

Reduce friction between mechanical parts

Reducing wear of mechanical components

Guard against corrosion

Provide engine cooling

But, the wrong choice of engine oil could cause the opposite anticipated effect:

A low viscosity causes contact between the parts which accelerate wear and leaks. A viscosity too high can cause an inability to power up and trouble getting started.

An index of viscosity too low may result in too much dilution when the oil is hot. Likewise, an oil that is too dense cold.

Foaming oil can cause loss of the lubricating properties as well as loss of oil inside the engine. The oil must not be insecure to oxidation or chemical attack to protect its benefits. The decomposition of an oil on hot metal components may result in a deposited brown or yellow layer, also known as “varnish” or “lacquer”. The layer is then transformed into solid carbon, which hinders the motion of mechanical components.


Each oil is made up of base oils as well as additives. Base oils are the base product. They are mineral, hydro-cracked, or completely synthetic. They are made through various refinement processes, and then enriched by adding additives that enhance the fundamental properties of motor oil.

Different types of oil: mineral semi-synthetic synthetic:

Mineral oil is a byproduct of distillation of petroleum. It is generally less costly in comparison to synthetic oil it’s not being used in modern engines but in older, non-turbocharged petrol and diesel automobiles. Mineral oil-powered vehicles require more frequent oil replacement since the oil gradually begins to lose its lubricating capabilities.

Synthetic oil is manufactured created, which is higher priced than the mineral oils because of the more complex design procedure. It is designed for diesel and gasoline engines, and is resistant to heat and age. Changes in oil are further apart. Changes in oil are not as frequent as mineral oils.

Additives that work on the base oil:

Pour point improvement. The additive alters the threshold of hardening for the oil at low temperatures. This can result in an oil that can be used at very low temperatures.

Increased viscosity index. The additive affects the change in viscosity and viscosity when it is exposed to significant changes in temperature.

Anti-foam properties. Oil may foam when in contact with air, which can cause damage to the engine components.

Antioxidant properties. The oil begins to oxidize with time and loses its lubricating qualities the additive slows this process, and also increases the life span for the oil.

Additives that directly affect the surface of the material:

Increased coefficient of friction a film of oil on the parts of the engine to reduce wear and friction, mercedes oil change.

Anticorrosion characteristics: The additive guards the engine against corrosion.

These are the primary properties of the additives found in oil for engines, and the list of additives is not complete.


Selecting the right engine oil for your vehicle is a delicate process It is easy to get lost in the arguments for brands, viscosity indexes as well as international standard.

Checking the maintenance log is an important step to ensure that you don’t make any mistakes and to select the correct oil. The manufacturer suggests a specific type of oil that is recommended according to the engine as well as the time of the entry to service for the car. It is only necessary to follow the manufacturer’s suggestions regarding viscosity grades as well as international standards to be followed.

For normal vehicles it is crucial to adhere to the recommended oil by your manufacturer . To select the oil you want to use and identify the kind of engine you have that you are using, the registration number on the vehicle will be the primary element, while the year of the vehicle’s release is the next important factor. There are however variations:

Technology advancements are advancing engines that are more precise machine tolerances, but also because pollution control standards are evolving.”


Before we get into the particulars, it is crucial to establish the concept of viscosity. In the Larousse dictionary, it’s “the characteristic of the physical properties in a fluid which is the result of a relationship between stresses and strains. 

As a rule the manual that you receive for servicing your vehicle doesn’t specify a specific viscosity class instead, it specifies the range of viscosity based on the usage of your vehicle as well as the weather conditions within the area you operate. It is crucial to know it.

The SAE (Society of Automotive Engineers) has established an array of cold and hot viscosity levels to be used to describe. The grade is displayed in motor oil bottles with the combination with two numbers, separated from each other by letters “W” which stands for “winter”.

The number that is before “W “W” indicates the viscosity of the oil at a cold temperature. A lower number will result in faster cold start and better the lubrication process. Example An example: A 0W30 oil will be more fluid in cold temperatures than an oil 5W30. The number following “W” indicates the viscosity of the oil at a certain temperature. A higher number offers greater protection from hot.


In addition to viscosity grade and viscosity grades, it is essential to think about the guidelines for the use of engine oil. The requirements to be met to are listed in the maintenance manual for your vehicle and are listed on the bottles for engine oil.

The two main ones of these are European standards ACEA (European Automobile Manufacturers Association) and the American standard API (American Petroleum Institute). Some car manufacturers issue additional requirements to international standards, these are manufacturer-specific standards. In this case, a decoding exercise is required.

ACEA European standard:

Within the ACEA classification the letter denotes four possible groups of applications

Tourism Essence

Passenger Diesel

Diesel and gasoline for tourism, according to specific standards

utility diesel

The figure represents the amount of oil in the engine according to the kind of engine. The higher the value higher, the more effective the oil is:

Entry stage


High end

The top of the line for direct injection engine

Extremely high-end

American API standard

For the API classification the first letter signifies the type of engine:



The second letter indicates an index of performance. The further a letter is located in an alphabetical order, the more up-to-date the technology utilized.

Example of the petrol engine, the SN motor oil specification is much more up-to-date in comparison to those using the SJ standard.

Car manufacturer standards:

To get approval the oil of a manufacturer (Peugeot as well as BMW for instance) depends on the control procedure and the specifications that are based on international standard.

Today, all car makers use their own standards for engine oil. This is the situation for Volkswagen, Ford, BMW, General Motors, Fiat, Mercedes Benz, PSA Peugeot Citroen, Renault. Also, make sure to read the user manual to your vehicle.


Viscosity grades, standards for use, and the oil intervals that are recommended by the manufacturer are unavoidable factors, however they’re not the only criteria to determine the type of engine oil.

Consumption of oil is influenced by the speed of your engine. The more RPM you have the higher the amount of oil will use. In reality, more pressure is applied to certain areas of the engine which allows oil to move through the crankcase and into the combustion chamber.

There are a variety of reasons that can cut down the time between oil changes:

Traffic jams

Short distance driving

Engine oil quality

Cold start

Very low or high temperatures


“Yes it’s important. Oils stamped large surface for example, are not oils of the same quality, they are not totally noble. There is a percentage of recycled oil. They are attractive in terms of price but do not have the same quality as branded products.”
