Oil is the main consumable and the most important component for good work Mercedes engine. The performance of the engine and its guaranteed period services. Car manufacturers are well aware of this and therefore create their own maintenance regulations, as well as forcibly, in order to maintain a guarantee, they are obliged to change engine oil at intervals of 10 and 15 thousand kilometers.
What kind of oil to fill in a Mercedes? There are many points of view, as well as a variety of oils. But concern Daimler decided to simplify the answer to this question and in 2011 began to produce under his own brand the original engine oil Mercedes. And it turned out to be an extremely effective marketing and financial decision!
Of course, Mercedes does not produce motor oil on its own, but purchases from leading manufacturers (Mobil, Shell, Fuchs, etc.), then packaging and labeling under its own brand. But for the end buyer, this simplified the selection process, because with this step, the manufacturer himself made the choice for the client, guaranteeing quality and reliability. And unlike other car companies, Mercedes now offers full line consumables for complete maintenance.
During the time that motor oil began to be produced under the sign of a star, it has successfully established itself. At the moment, under the name of the original Mercedes engine oil, several types of oils are produced, including for forced AMG engines. Each of them has its own tolerance and its own unique characteristics.
- Old oils from tolerance sheet 229.3 and 229.31 are almost never used at the moment;
- New synthetic oils With Mercedes approval 229.5 for gasoline engines and 229.51 for diesel engines;
- The latest engine oil with a tolerance of 229.52 for diesel engines.
Mercedes engine oil change
The manufacturer's regulation states mandatory replacement engine oil as planned. Maintenance intervals depend on many factors - the manner of operation, the statute of limitations of the previous maintenance, the distance traveled since the last maintenance.
Structural elements and operating materials must be coordinated with each other. Mercedes-Benz recommends that you only use products that have been tested and approved by Mercedes-Benz. They are listed in the relevant sections of this "Operating Instructions".
You can recognize the operating fluids approved by Mercedes-Benz by the following markings on the containers:
MB-Freigabe (Admission "Mercedes? Benz", for example: MB-Freigabe 229.51),
MB-Approval (Admission "Mercedes? Benz", for example: MB-Approval 229.51).

Do not mix such fuel with the fuel recommended for your vehicle. Do not use additives. Otherwise, engine damage may result. Exceptions are cleaning additives for removing and preventing deposits. Only cleaning additives recommended by Mercedes-Benz may be added to petrol, see "Additives". You can obtain further information in this regard at any Mercedes-Benz service point.
E10 fuel contains up to 10% bioethanol. Your vehicle has been adapted to refuel with E10 petrol. Your car can be filled with E10 petrol.
As an exception, and only if it is not possible to refuel the recommended quality, the car may be temporarily refueled with regular unleaded gasoline with O.CH.I.M. 91 / O.Ch.M.M. 82. As a result, engine power may decrease and fuel consumption may increase. Avoid driving with a full engine load and sharp accelerations. Under no circumstances fill your car with gasoline with a lower F.H.I.M. / O.Ch.M.M.
In some countries, commercially available gasoline may not be desulfurized enough. The use of such gasoline may temporarily cause odor formation, especially when driving short distances. The odor formation is reduced as soon as refueling with sulfur-free fuel (10 ppm sulfur content) is performed again.
GLK 350 4MATIC
Refuel your vehicle only with Super unleaded sulfur-free gasoline with O.H.I.M. not less than 95 / O.Ch.M.M. not less than 85, complying with the requirements of the European standard EN 228, or gasoline of similar quality.
Otherwise, engine performance may be adversely affected or the exhaust gas aftertreatment system may be damaged.
In some countries, commercially available gasoline may not be desulfurized enough. The use of such gasoline may temporarily cause odor formation, especially when driving short distances. The odor formation is reduced as soon as the sulfur-free fuel (10 ppm sulfur content) is refilled.
Additives
Operating the engine with additional fuel additives may result in engine damage. Therefore, do not add any additives to the fuel. The exception is additives for the removal and prevention of deposits. Only additives recommended by Mercedes-Benz may be added to gasoline. Follow the directions for using the product in the instructions that come with it. Further information on recommended additives can be obtained from any Mercedes-Benz Service Center.
In some countries, the quality of commercially available fuel may not be sufficient. The use of this fuel may lead to the formation of deposits.

AdBlue® reducing agent is a water-soluble exhaust gas aftertreatment for diesel engines. He is:
non-toxic,
colorless and
Flammable, odorless liquid.
If the AdBlue® tank is opened, a small amount of ammonia vapor may escape.
Ammonia vapors have a pungent odor and are primarily irritating to the skin, mucous membranes and eyes. As a result, there may be a burning sensation in the nose, throat and eyes. Coughing fits and lacrimation are also possible.
Do not inhale escaping ammonia fumes. Fill the AdBlue® tank only in well ventilated rooms.
Low outdoor temperature
Freezing of the AdBlue® reductant occurs at a temperature of approximately 11°C. The vehicle is factory-equipped with an AdBlue® preheater. Thus, operation in the winter period is also ensured at temperatures below 11 .
Additives
Use only AdBlue® reducing agent that complies with ISO 22241. Do not add any special additives to AdBlue® reducing agent and do not dilute it with water. Otherwise, the BlueTEC exhaust gas aftertreatment system may be destroyed.
Purity
Contamination of the AdBlue® reducing agent, e.g. with other operating fluids, cleaning agents, leads to:
Increasing emission values,
Damage to the catalyst
Malfunctions of the BlueTec exhaust aftertreatment system.
The cleanliness of the AdBlue® reductant is especially important to avoid malfunctions in the BlueTEC exhaust gas aftertreatment system.
If the AdBlue® is drained from the tank, for example during repairs, it must not be refilled into the tank. The purity of the product is no longer ensured.

Engine oil viscosity
Viscosity characterizes the fluidity of a liquid. When it comes to motor oil, high viscosity is equivalent to its thick flow, and low viscosity is its fluidity.
Depending on the outside temperature, use engine oil of the prescribed SAE grade (viscosity). The table shows which prescribed SAE grades viscosity is recommended. The properties of engine oils at low temperatures can deteriorate markedly due to aging or the ingress of soot and fuel into the engine oil during vehicle operation. Therefore, we strongly recommend that you regularly change the oil with an approved SAE grade engine oil.
The qualitative composition of engine oil affects the resource, efficiency and common work engine. Therefore, when choosing a lubricant, it is worth considering not only its base (synthetic, semi-synthetic, mineral), but also the group, class, and also the viscosity of the liquid. This article describes the characteristics of the recommended engine oil for Mercedes-Benz E Class.
