    Foreword

    GCC Standardization Organization (GSO) is a regional Organization which

    consists of the National Standards Bodies of GCC member States. One of

    GSO main functions is to issue Gulf Standards / Technical regulations

    through specialized technical committees (TCs).

    GSO through the technical program of committee TC No7 "Gulf Technical

    committee for Oil & Gas Industry" has updated the Gulf technical Regulation No. GSO 1785:2007 Lubricating Oils for Internal Combustion

    Engines" The Updated Standard has been prepared by (UNITED ARAB

    EMIRATES) this will withdrawn and replace GSO 1785:2007.

    The draft has been prepared based on relevant, International and National

    Standards and references.

    This technical Regulation has been approved as a Gulf (Standard / Technical

    Regulation) by GSO Board of Directors in its meeting No. ( ), held on

    / / H, / / G. The approved standard will replace and

    supersede the GSO standard N.( / ).

    Lubricating Oils for Internal Combustion Engines

    1. Scope And Field of Application The Gulf standard is concerned with lubricating oils for internal combustion

    engines suitable for gasoline and diesel engine services excluding marine

    application.

    2. Complementary References*

    2.1 GSO 126/1990 Methods of Sampling lubricating Oils.

    2.2 GSO ISO 3987:2011 Petroleum products - Lubricating oils and additives - Determination of sulfated ash

    2.3 GSO 873/1997 Determination of Apparent Viscosity for Engine Oils at Low Temperature Using the Cold Crank Simulator.

    2.4 GSO896/1997 Determination of Phosphorous Content in Lubricating Oils and Additives.

    2.5 GSO1078/2003 Determination of Kinematic Viscosity and Dynamic Viscosity for Petroleum Products..

    2.6 GSO ISO 2909/2008 Calculation of Viscosity Index from Kinematic Viscosity.

    2.7 GSO ISO 3771/2011 Determination of Base Number-Perchloric Acid Potentiometric Titration Method.

    2.8 GSO ISO 6247/2008 Determination of Foaming Characteristics of Lubricating Oils.

    3. Definition 3.1 Mineral Base oil: Petroleum product produced after refining,

    (separating fuel distillates) by extracting asphalt, aromatics, resins,

    unstable materials, wax and moisture to improve its characteristics.

    Also it can be separate mineral oil base types according to whether

    they are Conventional or hydro-processed. Conventional base oils are

    refined using traditional methods (applying chemicals) and tend to

    leave undesirables behind, such as sulfur, oxygen, nitrogen and carbon

  • 3

    GSO STANDARD GSO 1785 /2012 compounds, and trace metals. These can affect the performance of the

    oil.

    Mineral base oils that have been hydro-processed have undergone

    additional, more advanced refining processes than their conventional

    counterparts. The name "hydro-processed" is derived from the fact

    that refineries use hydrogen reactions (in a process known as hydro-

    cracking) to remove impurities. When base oils are subjected to even

    more hydroprocessing, they attain the status of severe

    hydroprocessed oils, which means they contain minimal amounts of

    impurities.

    Hydro-isomerized mineral oils reconstruct cracked waxes into

    branched paraffins. This technology is growing globally to meet

    global standards for lubricants.

    3.2 Base stock: Mineral or synthetic oil or mixture of both.

    3.3 Additives: Chemical materials designed to be mixed with base stocks to enhance its performance properties.

    3.4 Lubrication: The act of adding lubricating oil to reduce friction and wear between the moving parts, to control the increase in temperature

    rise caused by the friction, to minimize corrosion and to remove

    residues resulting from internal combustion.

    4. Classification Lubricating oils are classified according to their viscosity and

    performance as follows:

    4.1 Classification according to viscosity

    Lubricating oils are classified according to viscosity based on SAE

    classification (see Table 1).

    Multigrade oils are the combination of winter (W) and summer

    grades.

    4.2 Classification according to performance

    Lubricating oils are classified according to performance based on API

    classification (see Table 2& Table 3).

    Multigrade oils are the combination of winter (W) and summer

    grades.

    4.2.1 Service categories for passenger car oils:

    The lubricants covered by these categories are for gasoline

    passenger cars, some trucks and off-highway equipment. (Service

    category S).

    Note: The letter following service category S indicates the performance category of the oils.

    4.2.1.1. SJ-1997 Gasoline Engine Service Category SJ was adopted in 1996 to describe engine oil and was

    first mandated in 1997. It is for use in service typical of gasoline

    engines in present and earlier passenger cars, van and light trucks

    operating under vehicle manufacturers recommended maintenance

    procedures. Oils meeting API SJ requirement have been tested

    according to The American Chemistry Council (ACC) Product

    Approval Code of Practice and may utilize the API base oil

    interchange and viscosity grade engine testing guidelines. (They

    may be used where API Service Obsolete Categories SH and earlier

    categories are recommended). Note: SJ represents the minimum category used in this gulf standard.

    4.2.1.2. SL-2001 Gasoline Engine Service Category SL was adopted to describe engine oils for use in 2001.

    These oils are use in service typical of gasoline engines in present

    and earlier passenger cars, sport utility vehicles, vans and light

    trucks operating under vehicle manufacturers, recommended

    maintenance procedure. Engine oils that meet API service category

    SL requirements have been tested according to the American

    Chemistry Council (ACC) Product Approval Code of Practice and

    may utilize the API Base Oil Interchange and Viscosity Grade

    Engine Testing Guidelines. They may be used where API Service

    Category SJ and earlier categories are recommended.

    4.2.1.3. SM-2005 Gasoline Engine Service Category SM was adopted for use in describing engine oils available

    in 2004. These oils are for use in service of gasoline engines in

    current and earlier passenger cars, sport utility vehicles, vans, and

    light-duty trucks operating under vehicle manufacturers

    recommended maintenance procedures.

    Engine oils that the API Service Category SM designation may be

    used where API Service Category SL and earlier S categories have

    been recommended.

    Engine oils meeting API Service Category SM requirements have

    been tested according to American chemistry Council (ACC)

    Product Approval Code of Practice and may utilize the API Base Oil

    Interchangeability and viscosity engine testing guidelines.

    4.2.1.4. SN-2010 Gasoline Engine Service API Service Category SN was for use in describing Engine Oils

    available in 2010. These oils are for use in service typical gasoline

    engines in current and earlier passenger cars. Sport utility vehicles,

    vans, and light-duty trucks operating under vehicle manufacturers

    recommended maintenance procedures.

    The API lubricants Group finalized the user language and test

    requirements for both API SN and its supplemental Category-

    Resource Conserving (RC). This new supplemental category

    expands the previous Energy Conserving supplemental Category

    (which provided only fuel economy claims) by also adding greater

    emission system protection, turbocharger

    Protection and enabling engines to operate on ethanol-containing

    fuels up to E85. API SN, when licensed with Resource Conserving,

    is equivalent to ILSAC GF-5.

    The first allowable license date for API SN coincides with the

    ILSAC GF-5 first license date of October 1, 2010.

    4.2.2. Categories for Diesel Engines Oils The lubricants covered by this category commercial (category C)

    cover diesel engine t
