What do Mercedes oil tolerances show? This question is of interest to many motorists. The automobile concern from Germany Daimler AG today is rightfully among the leaders in vehicle manufacturers. Last but not least, the auto giant owes its success and fame to the Mercedes-Benz brand, which has been owned by it for over 100 years. All this time, cars of this brand were considered one of the most reliable. The foregoing is true for all groups of vehicles from this manufacturer, regardless of which type the car belongs to.
For a long time, Mercedes vehicles have been firmly held at the top of the pyramid of the most prestigious cars.
For a long time, vehicles of this brand are firmly held at the top of the pyramid of the most prestigious cars. For such premium-class devices, lubricants must also be of the appropriate quality level. To indicate the quality standard, the manufacturer introduced the concept of tolerance.
What is an oil tolerance?
A tolerance is an alphanumeric set that informs about the characteristics of a lubricant. This marking must be given in the service book of the Mercedes-Benz car. By comparing the markings from the service book with the markings on the oil canister, the car owner has the opportunity to purchase exactly the oil that the manufacturer intended to use in this car. This system quite clearly formalizes the quality indicators of the oil product that enters the lubrication system of the Mercedes-Benz engine. The first indication that a product has received such access is a character string beginning with the letters MB at the beginning of the document.
The procedure for obtaining a quality certificate from Mercedes-Benz is quite complicated even for the manufacturer himself, whose lubricant claims to be approved.
In order for a branded approval mark to appear on a container with an oil product, the oil product must pass a number of serious tests. Daimler AG puts forward strict conditions for the oil to meet the required quality class. A candidate lubricant must pass certain tests in order to obtain specific Mercedes oil approvals. The characteristics determined in this way are compared with the manufacturer's quality requirements, based on the result of such a comparison, a conclusion is made about the possibility of issuing a certificate from Daimler AG to the applicant.
With such a formulation of the issue of quality certificates for Mercedes-Benz vehicles, quite a lot is issued, so let's try to consider the most popular product quality documents.
A similar lubricant is poured into vehicles equipped with exhaust aftertreatment accessories. There are a lot of such tolerances, the main thing is not to forget about the hint that the manufacturer gives in the car's service book.

Demanded oil quality documents
MB 229.1. This document defines the range of oil products for filling in Mercedes-Benz vehicles, which were produced over several years: in 1998, 1999, 2000, 2001 and 2002. These are diesel vehicles (OM648, OM647, OM646) and petrol vehicles (M28, M271 and M275). This transport provided for quite serious standards for the amount of soot and soot.
Lubricants with increased resistance to thermal stress were required. The oil product should protect the engine elements as much as possible from wear and corrosion. The requirements, it would seem, are standard for any modern oil, but Mercedes manufacturers categorically prohibit the use of this brand of oil in the engines of newer cars. In these cases, Liqui Moly OPTIMAL Diesel SAE 10W-40, OPTIMAL SAE 10W-40 lubricants are used. Suitable products from ARECA F4000 5W-40, S3000 10W-40, S 3000 DIESEL 10W-40. MEGUIN products are represented by SUPER LL FAMO 10W-40 and MEGOL HD-C3 15W-40 oils.
MV 229.3. Lubricants certified for this approval are intended for use in motors of machines manufactured from the conveyor starting in 2003. These include Compressor petrol engines and CDI diesel engines equipped with ASSYST PLUS devices. Unlike the lubricants presented in the previous group, these lubricants primarily provide maximum fuel economy. Then come the increased ability to resist thermal oxidation and the formation of soot. Lubricants Liqui Moly Synthoil High Tech SAE 5W-40, OPTIMAL Synth SAE 5W-40, as well as ARECA F4500 5W-40, F4500 DIESEL 5W-40, MEGUIN ULTRA PERFORMANCE LONGLIFE 5W-40 meet all of the above conditions.
MB 229.31. Petroleum products from a canister adorned with this sign are intended for passenger cars and minibuses with DPF filters that trap soot and exhaust gas cleaning devices. These oil products meet the requirements of the Low SAPS class, which indicates a low sulfur content in them. Traces of phosphorus and its compounds in these products contain a minimum amount. A lubricant suitable for motors in such cases is Liqui Moly Top Tec 4100 5W-40.
MV 229.5. Oils that have received this quality certificate can be filled into Mercedes engines manufactured by the concern after 2003. This lubricant meets the highest requirements that can only be made to a lubricant. This oil can withstand a run of up to 40,000 kilometers, while being an almost environmentally friendly product. When such a lubricant is used in the engine, significant fuel savings are achieved. It is worth paying attention to Liqui Moly LEICHTLAUF HIGH TECH SAE 5W-40, Molygen NEW SAE 5W-40, MEGUIN QUALITY 5W-30 and HIGH CONDITION SAE 5W-40 lubricants.
MB 229.51. A similar certificate of quality is obtained by Low SAPS class oil products, which guarantee high environmental safety of Mercedes gasoline and diesel engines. Their composition contributes to the organization of optimal fuel consumption as much as possible, they work for quite a long time before they have to be replaced.
Oil is the main consumable and the most important component for the proper operation of the Mercedes engine. The performance of the motor and its guaranteed service life directly depend on the quality of the oil and its condition. 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 the Daimler concern decided to simplify the answer to this question and in 2011 began to produce original Mercedes engine oil under its brand. 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 a complete line of 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.

API CLASSIFICATION
The American Petroleum Institute (API) is developing international requirements for the quality of oils and criteria for their verification. The letter S indicates that this classification applies to gasoline engines, the letter C - to diesel. The next letter indicates the classification of the oil. API-SL is the latest classification to date, which defines the highest quality oil for gasoline engines.
ACEA SPECIFICATION
The ACEA Association (Association des Constructeurs European d "Automobiles) has been the official successor of the CCMS association since 01.01.96. They determine the quality of motor oils in accordance with European requirements. The new ACEA classifications have replaced the old CCMS requirements. The new classifications for gasoline engines of cars have the following designations: A1-98, A2-96 edition 2, AZ-98, which replaced the old designations CCMS G4 and G5. For diesel engines of cars, the designations are: B1-98, B2-98, B3-98, B4-98, which replace the old designation CCMC PD2.For diesel engines of trucks, the following designations apply: E1 -96 edition 2, E2-96 edition 2, E3-96 edition 2, E4-99, E5-99.
AUTOMOTIVE COMPANY APPROVALS
Various car manufacturers impose additional requirements on engine oils: Mercedes-Benz 227.1 and 228.1 for truck diesel engines, Mercedes Benz 228.3 and 228.5 for truck diesel engines with extended oil change intervals, Mercedes-Benz 229.1 and 229.3 for gasoline engines.
VISCOSITY
Viscosity determines the amount of internal friction in a fluid. It depends to a large extent on temperature and shows by means of a numerical value, for example, 5 W-40), how the oil behaves at low (5W in winter) and high temperatures (40 in summer). For example, motor oil 5 W-40 can be used in winter at temperatures down to -30 ° C and in summer at temperatures up to 35 ° C
ADDITIVES
Additives are chemically active substances. They are added to the oil to improve their characteristics and give them new properties. Antioxidants, for example, increase the resistance of the oil to aging, wear-protective additives protect the engine from increased wear, detergent additives give the oil cleaning properties. Depending on the area of application and load properties, various additives are added to oils in different quantities. In professional language, they say: maspo is alloyed. In modern oils, the proportion of additives is from 15 to 20%
MINERAL ENGINE OILS
Traditional motor oils are made from mineral oils. These oils, however, are limited in their ability to meet ever-increasing demands for extended oil change intervals, increased engine power and anti-friction properties. Typical viscosity values for mineral oils are: 15 W-40 or 20 W-50.
HYDROCRACKING (HC) ENGINE OILS
Hydrocracked oils are mineral base oils that have undergone complex processing. They contain a small amount of synthetic components. Their typical viscosity value is SAE 10W-40
SEMI-SYNTHETIC ENGINE OILS
Semi-synthetic engine oils are mineral oils with the addition of synthetic components. These components improve the properties of oils during cold start of the engine, keep the engine clean and provide good wear protection. A typical viscosity value for semi-synthetic oils is 10 W-40.
SYNTHETIC ENGINE OILS
Synthetic base oils serve as the basis for the production of engine oils with significantly improved properties. Synthetic engine oils are suitable for both gasoline and diesel engines, provide optimal wear protection, good lubrication during cold starts, reduce friction in the engine and keep it clean. They meet the highest quality standards according to API, ACEA and according to the tolerances of automotive companies. Typical viscosities for synthetic oils are OW-4O and 5W-40.
DIESEL ENGINE OILS
Currently, the ACEA specification VZ-98 and V4-98 and VW 505.00 brand approval from Volkswagen make the highest requirements for diesel and turbodiesel engines of passenger cars. These oils are suitable for both turbocharged and non-turbocharged diesel engines.
"EASY-STROKE" OILS (LEICHTLAUF)
These oils have a low viscosity at low temperatures and are characterized by increased thermal and oxidative stability. The oil pump operates in an optimal mode, ensuring oil is pumped through the channels at low temperatures. Thanks to their viscosity-temperature characteristics and modern high-tech additives, they help to reduce fuel consumption. Typical viscosity values: SAE OW-30, OW-40, 5W-40, 10W-40.
ENGINE OILS WITH GOOD ANTI-FRICTION PROPERTIES
These oils have good fluidity at low temperatures, are characterized by low oil pump work and withstand high thermal loads. They provide reduced fuel consumption. Typical viscosity values for these oils: OW-40, 5W-40, 10 W-40.
ALL-SEASON ENGINE OILS
In our temperate climate, multigrade engine oils can be used all year round. In winter, they do not thicken too much, and in summer, at high engine temperatures, they do not thin too much, for example: OW-40, 5W-40, 10W-40, 15W-40, 20W-50.
MOLYBDENUM ADDITIVE MoS2
MoS2 (molybdenum disulfide) forms a strong film on the rubbing and sliding surfaces of the engine that can withstand high loads. Due to this, friction in the engine is reduced, its wear is reduced and the likelihood of motor failure is reduced. Scientific studies have shown that when using MoS2, oil and fuel consumption is reduced, and wear is reduced by more than 50%. Despite all efforts to make the surface of metal parts smoother, it remains with microscopic irregularities. These irregularities are smoothed out by the formation of a film of MoS2. Thanks to this improvement in surface quality, the coefficient of friction and engine wear are reduced.
In total, two types of motor oils are considered in factory documents - primary fill oils and With service oils .
First, i.e. oils poured on the conveyor are assigned tolerance sheets 225.XX; The second - used when changing oil in engines in car services - tolerance sheets 228.XX and 229.XX.
First fill oils are very specific products. It is very difficult to buy them. Most likely you don't need to do this. There are many reasons: not all primary fill products fully comply with service approval sheets.
For example, for engines M272 , M273 , M276 and M278 oils of primary filling from sheets are used 225.16 and 225.26 , which are essentially LowSAPS oils, i.e. oils with a low content of sulfur and phosphorus, low ash content (fully complying with the tolerance sheets 229.31 and 229.51 , which are strictly forbidden to be used when changing the oil in service conditions) .
According to the nomenclature of oil producers for primary filling, Mercedes broke down the production program for each supplier - there are Shell (general partner in the lubricant business) and Fuchs, ExxonMobil and Petronas.
Engine oils from approval sheet 225.8 (primary fill oils, filled at the factory). For gasoline engines of the M1xx family and OM6xx diesel engines with a service interval of no more than 15,000 km (without Assyst) and 30,000 km (with Assyst), primary fill oil MB Erstbetriebmotorenoel Saphir N with a viscosity of 10W-40 from Fuchs from tolerance sheet 225.8 was used.
Engine oils from approval sheet 225.10 (primary fill oils, filled at the factory). The M266 and M275 engines and the OM640, 646 diesel engine (without a particulate filter) are initially filled with Shell Helix Ultra DC225.10 primary oil from the approval sheet 225.10 on the conveyor. Oil viscosity 5W-30. It was and remains the most common primary fill oil. It's just that document 223.1 is constantly changing and out of production engines fall out of it.
Engine oils from approval sheet 225.11 (primary fill oils, filled at the factory). The OM 629,640,646,660 diesel engine (with a particulate filter) is filled with MB Formula 225.11 5W-30 primary oil from ExxonMobil from tolerance sheet 225.11 (lowSpash); now replaced by approval sheet 225.17;
Engine oils from approval sheet 225.16 (primary fill oils, filled at the factory). The engines M271 (Repo and Evo), 272, 273 and 278 are filled with Fuchs Titan EM225.16 (HTHS 3.5) primary engine oil with a viscosity of 5W-30 from tolerance sheet 225.16 (lowSpash);
Engine oils from tolerance sheet 225.17 (primary fill oils, filled at the factory). OM642, 651 diesel engines without and with a particulate filter are filled with Syntium MB35D primary engine oil with a viscosity of 0W-30 (manufacturer - Petronas Lubricants International, Villastellone (Torino), Italy) from tolerance sheet 225.17 (corresponds to oils 229.31 and 229.51);
Engine oils from tolerance sheet 225.26 (primary fill oils, filled at the factory). Fuchs Titan EM225.16 (HTHS 2.9) primary fill oil with a viscosity of 5W-30 from tolerance sheet 225.26 (lowSpash) is poured into M276 engines. At the same time, all service documentation strictly says that it is impossible to use lowSAPS oils in M276 engines during further operation.
Engine oils from tolerance sheet 229.1. Used for diesel and petrol engines. Not applicable for diesel engines with DPF particulate filters (code 474) . The sheet appeared in 1997 along with the introduction of a new tolerance system. Complies with the European standard ACEA A3-04 or B3-04 (where A is the quality class for gasoline engines, B is for diesel engines, respectively; 2 or 4 is the performance class; "04" is the year the specification was published, i.e. 2004). Until 2004, classes A and B were separate, since the 2004 classification, classes A and B can be combined.
According to specification 223.2 on the dealer website bevo.mercedes-benz.com/oils from approval sheet 229.1 are not used on any of the currently produced engines! On motors manufactured before 2002 - please.
Engine oils from approval sheet 229.3 Used for diesel and petrol engines. Not applicable for diesel engines with DPF particulate filters (code 474) . Complies with the European standard ACEA A3-04 or B4-04 (it differs from oils 229.1 in high quality, low oxidizability, low content of chlorine and phosphorus).
Applicable:
- for all gasoline engines, except M278;
- for gasoline AMG engines, except: M152, M156, M157, M159, M275 AMG, M113 AMG, M112 AMG;
- from diesel engines (cannot be used only for cars with a DPF diesel particulate filter);
There is one specific engine - M155, installed on the Mercedes Benz SLR McLaren, for which approval sheet 229.3 is the only one. But not all oils from this leaf can be used. Only Mobil brand oils and only with SAE 5W-50 ratings. This is an agreement between the engine manufacturer AMG and its partner in terms of lubricants - ExxonMobil. As for the choice of a brand, this is more of a commerce than technology and technology, but the viscosity - I think - is the requirements of the designers (most likely this motor was simply created for such oil).
Engine oils from approval sheet 229.31 They are used for diesel cars with code 474 (DPF particulate filter), at least for these engines these oils were created. The sheet appeared in July 2003. Conforms to the European standard ACEA A3-04, B4-04 and C3-04 (C - class for Low SAPS oils). In addition, it can also be used in gasoline engines (but only: M266, M271). According to document SI18.00-P-0011A on engines 271 Evo, 112, 113, 272, 273, 276, 278 and 275, it is forbidden to use engine oils from approval sheets 229.31!
In general, these are already high matters, but stringent requirements for soot formation force oilers to reduce the content of zinc, calcium, molybdenum and other elements in oils, on which most of the usual additives are based.
A different principle of operation of additives is the main difference between oils 229.31 and 229.51 from 229.3 and 229.5. That. using e.g. 229.51 in a 273 motor can actually damage the motor.
Engine oils from approval sheet 229.5 Applicable to all petrol and diesel engines of Mercedes Benz passenger cars, except for diesel engines with a particulate filter (code 474 in the data card) . Conforms to the European standard ACEA A3-04 , B4-04 . The sheet appeared in May 2002.
Not so long ago, in the description of oil 229.5 on this page, it was written that sheet 229.5 is not applicable for engines M104, M119 and M166. I want to rehabilitate oils from tolerance sheet 229.5: except for the M166 baby and the M155 compressor monster, these oils are applicable to all gasoline and most Mercedes Benz diesel engines (hereinafter, we are talking only about cars). The fault is both mine and not mine: a whole bunch of mutually exclusive documents - according to some, the use of oil 229.5 in engines 104, 119, 120 is unacceptable. According to others - please (example: documents BF18.00-P-1000-01B and AP18.00-P-0101AA) . I have no right to cite documents in part or in full: intellectual property of Daimler AG. See WIS for yourself.
The confusion has led to the well-established opinion that the use of oils from sheet 229.5 on engines 104, 119 and 120 is unacceptable due to the use of paper oil filters in them, which, according to this opinion, are destroyed by the components of these oils. As a consequence, sheet 229.5 oils are considered to only work with fleece oil filters. This is mistake. The fact is that tolerance sheet oils began to be used on Mercedes back in May 2002, and A000 180 2609 fleece filters for M112/113/137 engines began to be delivered only from September 2003. This time. Secondly, in the oil systems of M111 engines, which, according to all documents, have a tolerance of 229.5, the same paper oil filters A104 180 01 09 are used. Thus, the historical linkage of oils from tolerance sheet 229.5 and fleece filters is just a coincidence, caused by an indispensable combination of both factors (both oil and filter) to increase the service interval (for example, for the M112, the interval when using this combination increases from 15,000 km to 20,000 km. In Germany). Apparently, by the time the documents for increasing the intervals were put into effect, it was believed that all cars with M104 and M119 engines were already out of production and it was simply pointless to change something in the maintenance system. It is clear that an increase in the service interval is a kind of advertising that promises to reduce the cost of maintaining a car, and therefore convinces you to buy a new car. It is financially unprofitable to convince to buy already sold cars, the money for which has long been eaten away.
There is one, but a big BUT! When using 229.5 in engines with a paper filter, the mileage should not really exceed 10,000 km.
Let me explain: among the many reasons, the very principle of a “long-playing” oil lies in a higher content of alkali, the task of which is to neutralize the oxidation products. The longer the oil should work, the more alkali should be stored in the oil: for oils 229.1 and 229.3, the base number TBN was 6.6 ... 8.6, for 229.5 - already in the region of 12. This alkali, among other things, “finishes off” the cellulose of the paper filter. The paper filter becomes brittle with the possibility of crumbling it. Fleece filters (they were called fleece in Russia. Translated from German Vlies - non-woven fabric. In fact, filters are made of two-layer polyester. The first layer is frame, the second is actually filtering) resist about 7 times longer and can work up to 50,000 km.
In fact, in engines with paper filters, oils from sheet 229.5 can be used, but at the same time reducing the service life even compared to 229.3.
As mentioned above, when using oils from tolerance sheet 229.5 and a fleece filter for gasoline M112, M113 and M137, it became possible to increase the service interval from 15,000 km to 20,000 km. This does not apply to motors 112.960/961 and 113.990/991/992 - for them the intervals remain the same.
Oils from approval sheet 229.5 obviously vary greatly in performance and are not equally useful for Mercedes Benz and AMG engines. So for AMG engines M112, M113, M152, M156, M157, M159, only oils from the XW-40 series are allowed, where X is 0.5.
Engine oils from approval sheet 229.51 They are used for diesel engines of Mercedes Benz passenger cars with a particulate filter (code 474 in the data card) . The sheet appeared in 2005. Conforms to the European standard ACEA A3-04, B4-04 and C3-04. In addition, it can also be used in gasoline engines, but only: M266, M271, M271Evo. Oddly enough, it can also be used in AMG gasoline engines M156 and M159. According to the document SI18.00-P-0011A on engines 112, 113, 272, 273, 276, 278 and 275, it is forbidden to use engine oils from approval sheets 229.51!
