API SJ SL or higher. Specification of motor oils by API. Classification of ILSAC, GOST, ASEA - which means and how to decrypt

This post fully decided to devote API CF. (API CF-2, API CF-4). What interesting in the CF API? What unites the CF-2 API and the CF-4 API under the flag of the API CF, and what is the difference between them? Let's start, perhaps, with the fact that the CF API is a class. motor oils In the API classification, finally enacted in 1994 (the CF-4 API class was implemented and acted against engines issued in 1990, and the CF-2 API was established only in 1994).

Class API CF. - These are motor oils for diesel engines With divided injection using high sulfur fuel (more than 0.5%). The ratio of engine oil to the CF API class implies additives that are more efficient (compared with the outdated and canceled CD class) prevent deposits and tarts on pistons and piston groups, and provide increased protection of sliding bearings containing copper.

API CF-2

The feature of the CF-2 API is that this class refers to two-stroke (2 - in the abbreviation) diesel engines operating in heavy conditions operation. CF-2 API class oil provide reinforced protection piston rings And the whole group of deposits and nagar ("climbing" rings, etc.), contain "reinforced" attacks from coking and sludge in a diesel engine.

CF-4 API

As for the CF-4 API, this class, which came into effect since 1990, combined motor oils for high-speed and powerful four-strokes (it says 4 in the Abbreviation API CF-4) diesel engines operating in different conditions operation. Ideally, these are powerful trunk tractors, "charged to the endless race" on the highway. With a turbocharged, so without it. Moreover, the additives used in the CF-4 API oils provide enhanced protection. piston group From nagar and overheating, even on forced engines (it was the privilege of the API class, but the CF-4 API successfully replaced it). Another feature of the CF-4 API. Oils of this class often correspond to API SJ (i.e. gasoline) class. In this case, it is necessary to coordinate the use of such oil in a gasoline engine with a manufacturer.

Feature API CF.

Forgot to note the feature of the API CF. The fact is that the CF API is the most "ancient" of the current API classes. But "Loading" does not detract from his merits. The presence of the CF API on the market today only emphasizes its specificity. API CF Engine Oils will provide best defense Piston group from Nagar when using high-fired fuel, as well as copper-containing bearings protection against wear and corrosion. Oils, certified API CF, provide oil pumpability, both in the usual way and with a compressor or supercharger.

Continuing the topic "API Classification" We will analyze the class API SL. API SL. introduced in July 2001 for multiclapped turbocharged engines equipped with exhaust control systems and neutralization systems. S. - means belonging to the gasoline class, L. - Belonging to the requirements of ecology tightened in 2001 and energy-saving properties of motor oils.
API SL implies the following improvement of motor oils

• low toxicity exhaust
• protection of exhaust control systems and neutralization
• increased wear
• strengthened Protection of Wristwed Temperature
• an extended substitute interval

Of course, all these improvements were relative to the SJ API, the previous API class. The SL API was a new, modern API class at the beginning of the new millennium. The SL API included motor oils for the 2000 release engines and acted until 2004, having transferred the next class.

API SL CF.

"Neighborhood" API SL with CF on the label (often encountered API SL CF) is the possibility of using oil and in diesel engines (). It does not diminishing "gasoline" properties, the engine oil API SL CF is ready for use in a diesel engine, even with the use of high sulfur fuel (high-teridate 0.5% or more). Refers to the 1994 diesel engines and later.

API SL ILSAC GF-3

An API SL oil (in the sense of the corresponding API SL) can be certified by category, which indicates fuel economy and maintaining this savings for the entire oil life.

Oil API SL CF

On this site there are descriptions and characteristics of motor oils corresponding to API SL CF. Read " Semi-synthetic engine oil for diesel engines»About Motor Oil API SL CF Guardol ECT 10W30 Family Brand ConocoPhillips and" Motor oil 15W40.»About such Motor Oil API SL CF Guardol Ect, only 15w40. , the same family brand ConocoPhillips.

Classification of motor oils Under the conditions of application and levels of operational properties, the American Oil Institute (API).

By classification Motor APIs Oils are divided by two categories: "S" (Service) and "C" (SMMERCIAL).

S (Service) - consists of categories of quality engine oils for gasoline engines going in chronological order. For each new generation An additional letter is assigned alphabetically: API SA, API SB, API SC, API SD, API SE, API SF, API SG, API SH and API SJ (Category SI - intentionally missed API, to eliminate confusion with an international system system).

API SA, API SB, API SC, API SD, API SE, API SF, API SG today is recognized as invalid, as outdated, but in some countries of these categories are still available, the category API SH is "conditionally acting" and can Used only as an additional, such as API CG-4 / SH.

The SL class was introduced 2001 and differs from SJ essentially the best antioxidant, anti-wear, anti-inflated properties, as well as less evaporation.

C (Commercial) - It consists of categories of quality and destination of oils for diesel engines going in chronological order. For each new generation is assigned an additional letter according to the alphabet: API CA, API CB, API CC, API CD, API CD-II, API CE, API CF, API CF-2, API CF-4, API CG-4 and API CH -four.

API CA, API CB, API CC, CD API, CD-II API today is invalidated as outdated, but in some countries oils of these categories are still available.

Classes of oils indicating the scope of the application are denoted by the letters of the Latin alphabet in ascending order behind the designation category: "SERVICE" (SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN), "Commercial" (CA, SV, SS, CD, CD +, CD-II, CE, CF-4, CF-2, CG-4, CH-4, CG-4). The numbers in the symbols of CDII, CF-4, CF-2 classes, CG-4 provide additional information about the applicability of the oils of this class in 2-clock or 4-stroke engines. The introduction of each new class was due to the tightening of oil requirements, in particular caused by environmental legislation, expanding the use of turbocharged engines, recycling of exhaust gases.

To refer to universal oils, i.e. Such which can be used to lubricate gasoline and diesel engines, adopted double marking, for example SF / CC, CF-4 / SH, etc.

The classification of motor oils by API was developed in 1969. It is quite common worldwide.

It is marked with products of well-known manufacturers, such as "Castrol", "Motul", Shell. Marking Indicates Type car Enginewhich is possible to fill the oil fluid. Its decoding is quite simple. Accordingly, with the classification of oils by API, all lubricants are divided into:

• S - auto oil for gasoline engines;
• C - consumables for diesel engines;
• EC - energy-saving car. They have high quality, low viscosity, fluidity, are able to reduce fuel costs.

Lubricants suitable for any motors are marked with a pair of characters. The 1st symbol is considered the main one indicates that the petroleum product is possible to pour in the engine of a different type. Example: Oil API SM / CF.

Categories Oil Massels on Gasoline

The classification of the API contains the following classes of oil for engine oil on gasoline:

1. SN - approved 01.10.2010. Contains limited quantity phosphorus. Compatible with new systems neutralizing exhaust, is energy saving.
2. SM - approved November 30, 2004. The class API SM is intended for gasoline engines produced today. Better than SL, protects motor spare parts from oxidation and early wear. Almost does not change its own characteristics in low-temperature conditions.
3. SL. Optimally for cars made in the twenty-first century. Accordingly, with the tolerances of automakers, this grease Used in multi-chamber, turbocharged power units that work on a depleted stuel. Eco-friendly oil, energy-saving.
4. SJ. Suitable for gasoline engines released after 1996. Such a car is intended for use in cars, sports cars, minibuses, small trucks. When it is used, a little nagar is formed, lubrication retains its properties in winter.
5. Sh. Optimally for the engine on gasoline, made after 1994. It is well opposed to nagaru, oxidation, wearing, corrosion exposure. You can pour in the passenger cars, minibuses, cargo transport. The main thing is to comply with the tolerances of manufacturers. They are listed in the table existing in the operational manual.
6. SG. Suitable for machines released not earlier than 1989. The additives contained in the car are protected from the corrosion exposure and rusting of the Spare Parts of the Power Unit.
7. Sf. Outdated category in the Specifications of the Motor Oils by API. The lubricant relating to it may be inserted into the engine made after 1980.
8. SE Suitable for engines released after 1972.
9. SD. Automotive for use in gasoline engines released after 1968 (outdated category). The oil was used in gasoline engine cars, freight transport.
10. SC. Oil fluid for engines made not before 1964. Usually used in the engines of the passenger cars, trucks 1964-1967 production.
11. SB. Lubricant for gasoline engines that have low power. Provided rather weak protection of motor bearings from wear, oxidation, corrosion exposure. Similar machine can not pour in modern car (if the opposite is not spelled out in the operational manual).
12. SA. It differs from previous oils by the fact that it can be used not only in gasoline, but also in diesel engines. Very outdated group of lubricants, which are not used almost anywhere today. Earlier quality protection Motor spare parts by means of additives was not particularly required, so the SA api oils were quite popular.

Categories Oil Oils on Diesel

API motor oil for diesel engine may refer to one of the following categories:

1. CJ-4. It was introduced 01.10.2006. It was designed specifically for high load motors. Lubrication meets the basic requirements for the formation of Nagar and solid elements for the 2007 power units. There are limitations for certain characteristics: the ash content should be less than one percent, the sulfur concentration is less than four tenth of the percent, phosphoric - less than inxisted and hundredths of percent. Oils related to this Quality Class on the API have all the advantages of lubricants from other categories. They are also well suited for modern power units, comply with the entered environmental standards.
2. CI-4 Plus. Lubrication forms little soot, evaporates weakly, practically does not oxidize in conditions high temperatures. API Specifications Certified in this class has passed approximately 17 tests during production.
3. CI-4. In the specification API is given Class entered fifteen years ago. Similar machines are used in today's motors on the diesel different types Injecting and supervision. They enter into particular dispersing and detergent additives. Consumables are resistant to heat-acid, have good dispersing indicators. They also significantly reduce the amount of smoke during operation. The volatility is reduced, evaporation begins when the temperature reaches three hundred seventy degrees Celsius. Extremely fluid oil, perfectly passes throughout the lubricant complex in severe frosts. Due to this, the wear of the sealing elements of the power unit decreases.
4. CH-4. Class introduced 01.12.1998. Lubricants are used in four-stroke DVS on diesel engine operated in high speed mode. They meet all the requirements for the content of toxic substances in exhaust. These requirements were taken nineteen years ago. Oil fluidsThis category is recommended to pour automakers from Europe, the United States of America into the engine. Lubricants are designed for use in engines that work on a very high-quality stuel containing no more than five tenth of the percent of sulfur. However, they can be pouring during a sulfur concentration that exceeds the established limit. This is especially important for South American, Asian, African states. Consumables contain additive substances well-protective valves from wear, which do not allow curly deposits on motor spare parts.
5. CG-4. This oil class on the API introduced twenty two years ago. Petroleum products, ranked in this category, need to pour into four-stroke engines on diesel (buses, trucks, tractors - transport, operated in highly loaded conditions and at high speeds). The level of sulfur in a combustion should not exceed five hundredths percent. You can also pour this oil in power unitsFor which there are no special requirements for fuel quality (sulfur concentration can reach up to five tenths percent). Lubricants that are certified in this class do not allow the wear of motor parts, the appearance of curbing deposits in piston system. Elements of the power unit are less oxidized, few foam and soot are formed (similar characteristics are very significant for today's bus and tractors motors). The main minus, which limits the massive use of such consumables, for example, in Eastern European and Asian countries, is that the oils are significantly dependent on the quality of fuel fuel.
6. CF-2. API CF 2 oils are intended for use in two-stroke engine on diesel engines operated in difficult conditions. Class introduced twenty three years ago. Such autosals are commonly poured into high-load engines.
7. CF-4. This includes lubricants designed for filling into four-stroke engines on diesel engines, produced after 1990. If the automaker does not indicate the opposite instrument manual, the oil can be used in MOX on gasoline.
8. CE. Automal for use in engines on diesel engaged not earlier than 1983. They were used in very powerful turbovigats, which are characterized by a significantly increased working pressure compared to other.
9. CD. The class was introduced in 1955. Such oils were often used in agriculture (tractor, combines).
10. CC. This class appeared in 1961. Petroleum products are ranked here, which can be poured into medium-wide engines.
11. CB. The class was adopted in 1949. He represented an improved class CA.
12. CA. Lubricants were poured exclusively into low-loaded power units on the diesel.

Transmission Oil categories

With classification transmission oils It is necessary to read that when choosing a transmission lubricant, be able to perform labeling. Through the designations on the canister it is possible to understand what the product indicators are from which additives and basic oils it consists.

1. GL-1. Are intended for cone-spiral, worm and mechanical PPC (without synchronizers) installed in trucks and special equipment.
2. GL-2. Optimal for worm gearbox, which work in low-speed and unlucky mode. Creately used in tractor techniques.
3. GL-3. Suitable for cone-spiral transmissions operating in medium conditions. Designed to lubricate spiral and other gearbox trucks. It is impossible to pour into hypoid transmissions.
4. GL-4. Automal for hypoid transmissions operating in high-speed mode with a small torque / low-speed mode with a large torque. Today, lubricant data is often used in synchronized PPCs.
5. GL-5. Lubricants are suitable for hypoid gearbox, which are functioning in conditions of severe load on the gear teeth and high speeds. Usually they are poured into transmissions with displaced axes. For synchronized manual transmission, petroleum products approved by the automaker should be used.
6. GL-6. Automas are designed to fill in hypoid gearbox with a large displacement. Today they are not used due to their full displacement with oils GL-5.

Oh yes - the eternal question "What oil pouring .."

In principle, the answer to it is within the competence of the manufacturer of a particular motorcycle model. The fact is that the engine and graduation system Designed to work with a specific type of oil.
In order for the consumer to do not break his head if he chooses the oil itself, each model has a list of parameters that allow you not to confuse: oil viscosity according to the standard SAE (By the American Association of Automotive Engineers) For example, 10W40 and its classification on the system API. ENGINE SERVICE CLASTIFICATION SYSTEM), for example SG. Data can be found in the User Manual manual.
This information is almost enough to choose oil.

An650 from 2002 to 2005 - API: SF or SG, SAE10W-40
An650 from 2006 to 2013 - API: SF or SG or SH or SJ, SAE10W-40
An400 C 1998 to 2006 - API: SF or SG, SAE10W-40
An400 from 2007 to N.VR. - API: SF or SG or SH or SJ, SAE10W-40
An250 C 1998 to 2006 - API: SF or SG, SAE10W-40
An250 from 2007 to N.Vr. - API: SF or SG or SH or SJ, SAE10W-40

in the same place, in the instruction manual, SUZUKI does not recommend to use energy-saving oils using API classification Some of the SH, SJ, SL and SM, having an EC icon (Energy Conserving).

Another factor affecting the choice of oils is the presence of additives for clutch operation in the oil bath. This is important for all years AN650. Those. These devices cast only oil for motorcycles. In AN400 and AN250, it is permissible to upload even automotive oil suitable for viscosity and API classification.
