Engine Oil( Motor Oil)
Engine Oil is an important part of the trading and training of Naft Andish Yekta PTE Company.
The company started importing one of the Fully Synthetic based motor oil brands from Japan in 2015 through Singapore.
The customers of this oil were reputable companies of Iran Benz( setareh iran co.), Toyota ( irtoya), reputable and large repair shops in Tehran and provincial centers, and the brand was viewed on the main site of German Benz standards and had approval certificates of MB229.5, MB2295.1, MB229.3, etc.
SAE : Society of Automotive Engineers -This society is responsible for establishing a classification system based solely on oil viscosity.Organization SAE works for the quality of motor oils of automotive and industrial lubricants while monitoring the quality of production based on the viscosity. Writing and displaying this standard on the containers of all lubricants is mandatory.
* Engine oil is made on the basis of two big types of base oil :
Mineral base - Synthetic base
*Mineral engine oils are from the bases of API groups 1, 2 & 3, and synthetic oils are from the bases of API group4 (PAO s) & group 5 (ESTER s ).
API : American Petroleum Institute - API is a big global standard organization.
-In its first 100 years, API has developed more than 7000
standards to enhance operational safety, environmental protection and
sustainability across the industry ...
* The advantages of groups 4and 5 (Fully Synthetic groups) compared to oil engine oils are many, including: long consumption life, high oxidation resistance, reduction of car engine fuel consumption, environmental compatibility, no corrosion, no friction, low SAPS ...
Disadvantages: They are expensive and not produced in many countries.
Important Note : semi synthetic motor oils are only blend of two base : ( %X mineral base oil groups 2 or 3 + %Y synthetic base oil groups 4 or 5 ) , and means depend on process & formulations of companies . semi-synthetic is not API base oil group .It is only for the purpose of market sales by companies.
Engine Oil Yekta Group, since 2015, has been importing 4th and 5th generation car lubricants under the TOTACHI brand as an exclusive representative from Japan and through Singapore.
Due to the valuable experiences of the founder of the company regarding car lubricants and his reputation in the oil industry, the above brand was introduced and recognized in the market very quickly and the star companies of Setareh Iran (Iran Mercedes Benz), Iran Toyota (IRTOYA) and many Ramak khodro dealerships The car (Ramakkhodro) became a regular customer of the company.
* Activity in this case: Imports from Japan, Singapore, Austria and in the coming months will open a factory for the production of automotive lubricants based on Fully Synthetic.
At API performance level of engines, S means is spark system( gasolines) engines & C means is commercial and passenger cars diesel engines.
API S :
API C - Series Services Classification For Commercial Cars DIESEL Engine Oil :
The current and previous API Service Categories are summarized in
convenient charts. Vehicle owners should refer to their owner's manuals
before consulting these charts. Oils may have more than one performance
For automotive gasoline engines, the latest engine oil service
category includes the performance properties of each earlier category.
If an automotive owner's manual calls for an API SN oil, an API SP oil
will provide full protection. For diesel engines, the latest category
usually - but not always - includes the performance properties of an
API’s Engine Oil Licensing and Certification System (EOLCS) is a
voluntary licensing and certification program that authorizes engine oil
marketers that meet specified requirements to use the API Engine Oil
Quality Marks. Launched in 1993, API’s Engine Oil Program is a
cooperative effort between the oil and additive industries and vehicle
and engine manufacturers Ford, General Motors, and Fiat Chrysler and
those represented by the Japan Automobile Manufacturers Association and
the Truck and Engine Manufacturers Association.
requirements and test methods are established by vehicle and engine
manufacturers and technical societies and trade associations such as
(ASTM), (SAE), and the American Chemistry Council (ACC).
SAE's charitable arm is the SAE Foundation, which supports many
programs, including A World In Motion® and the Collegiate Design Series.
Founded in 1905, SAE strives to serve its primary constituents in a
variety of ways. Through its globally-recognized magazines, Automotive
Engineering International, Aerospace Engineering, and Off Highway
Engineering, SAE informs the mobility community about the latest
developments in the field.
SAE's broad array of technical, historical, and statistical
publications are distributed to customers in more than 65 countries
annually. SAE's Training and Professional Development capabilities have
been expanded in the past 20 years - SAE now produces more than 450
separate professional development events every year.
ISO-International Organization for Standardization
ISO is a big global & international organization to all industry sections.ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
Each member body interested in a subject for which
a technical committee has been established has the right to be
represented on that committee.
International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
MIL-L engine oil quality level standard:
The word MIL-L stands for MILitary Lubricant, motor oil and lubricants related to military applications. Some of the quality levels of this standard are MIL-L46152A, MIL2104D, MIL-L2104A, B, MIL-L2104C, MIL-L45199B, and MIL-L46114. , 5.
Of course, there are many other classifications for the quality level of engine oil that are not general. Such as the classification of Volkswagen (VW), MAN (MAN), Mercedes-Benz and Mack.
In most of the countries and the dear country of Iran, among the above classifications, the most common API is the standard of the quality level of engine oil. Therefore, in detail, the quality level standard of engine oil is described in the section.
AGMA : American Gear Manufacturers Association
ILSAC : International Lubricants Standardization and Approval Committee
The ILSAC standards,
denoted by the terminology ILSAC GF-x, are based upon the API service
categories and bring additional performance requirements, for example
fuel economy improvement, and restrictions in the viscosity grades that
may claim to meet an ILSAC standard.
Founded in 1992, the International Lubricant
Standardization and Approval Committee (ILSAC) is an organization
through which Ford, General Motors, Chrysler and the Japan Automobile
Manufacturers Association, Inc. (JAMA) develop minimum performance
standards for passenger car engine oils used in gasoline fuelled
The ILSAC standards, denoted by the terminology ILSAC GF-x, are based
upon the API service categories and bring additional performance
requirements, for example fuel economy improvement, and restrictions in
the viscosity grades that may claim to meet an ILSAC standard.
ILSAC utilizes the API’s Engine Oil Licensing and Certification
System (EOLCS). This is a voluntary licensing and certification program
that authorizes engine oil marketers who meet specified requirements to
use the API Engine Oil Quality Marks. These emblems go directly on each
container of oil that retains the certification for and is there to help
consumers identify a engine oils for their gasoline-powered vehicles.
Only oils meeting the latest ILSAC standard may use the API
As you can see in the tables and diagrams above, engine oil is completely affected by its viscosity factor against engine temperature and geographical environment.
Therefore, in purchasing and using any type of engine oil, it is necessary to pay attention to the geographical conditions and type of technology of the year of manufacture of the car engine, as well as the number of cylinders and the type of mineral or synthetic base oil so that your car repair costs do not increase.
There are cars that have old technology but are still being produced and we need to pay attention to their engine type and degree of viscosity.
xx W is SAE viscosity grade The start time of the car is in the cold of the engine & yy is SAE viscosity grade at car driving

As you can see, the thin film of full synthetic engine oil has better protection than mineral engine oil due to the uniformity of the molecules that make up the oil.
The engine has always been the ultimate platform for identifying the
required quality of its oil. Even as engine design has changed to meet
performance, fuel efficiency and environmental standards, the engine
continues to be the ultimate arbiter of oil quality.
However, using the engine to measure oil quality in dynamometer tests
can be an expensive proposition. Even so, to help control warranty
costs, the development and use of engine tests is unavoidable for engine
manufacturers when determining the oil quality needed for a particular
design or component.
Although necessary, generating repeatable dynamometer tests for an
engine can be challenging. As engine design has progressively increased
power from smaller engines, the difficulty of establishing repeatable
dynamometer tests has grown even more rapidly. Fortunately, once the
quality level has been determined on the dynamometer or in the field,
there is a much less expensive approach that can be applied to more
precisely appraise the oil quality.
Engine oil is for a car, what blood is for a human being. It won’t be
wrong to say that any vehicle can’t survive without engine oil. It
serves as a protection for car components against wear and tear even
when temperatures inside the motor go in access of 120 degrees.
choosing the wrong grade of engine oil for a car or opting for an
inferior quality one can have very bad results. To serve the engine, oil must possess certain physical and chemical
During the oil’s service, the engine generates a number of
operating stresses that adversely affect the long-term ability of the
oil to function at a consistently high level. Service conditions may
also vary widely depending on the environment and the way the vehicle is
Consequently, choosing an engine oil to meet particular service
needs and conditions requires knowledge of several important oil
properties, including viscosity.
This is because wrong fluids lead to increased friction between the
movings parts of the engine, which in turn causes accelerated wear and
tear. Also, using the wrong viscosity of engine oil can lead to a huge
drop in the performance of the car. Also, in case of an oil leak, the
engine is sure to seize, which will lead to an expenditure of lakhs in
repairs. Therefore, it’s really important to know how to choose the best engine oil for a car.
