Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Tourism, Trade and Industry established by the Act of Parliament of 1983, of the Laws of Uganda. UNBS is
The work of preparing Uganda standards is carried out through Technical Committees. A Technical Committee is established to deliberate on standards in a given field or area and consists of representatives of consumers, traders, academicians, manufacturers, Government and other stake-holders.
Draft Uganda standards adopted by the Technical Committee are widely circulated to stake-holders and the general public for comments which are reviewed before recommending them to the National Standards Council for declaration as national standards.
This Uganda Standard was elaborated by the Sub committee on Petroleum products under the guidance the Uganda National Bureau of Standards (UNBS) Technical Committee on the Chemicals and Environment. It specifies the performance requirements of both automotive diesel and petrol engine oils based on the API (American petroleum Institute) classification.

UGANDA STANDARD SPECIFICATION FOR ENGINE LUBRICATING OIL (FOR API SERVICES SF AND CD)
This Uganda standard covers crankcase lubricating oils, for automotive type internal combustion engines, meeting or exceeding the, API service classification
The standard does not cover the chemical requirements for oils as these vary with the type of additive used in the formulation of a particular oil for a particular category.
NOTES –
The following standards contain provisions which, through reference in this text, constitute provisions of this part of US 249. All standards are subject to revision and, since any reference to a standard is deemed to be a reference to the latest edition of that standard, parties to agreements based on this part of US 249 are encouraged to take steps to ensure the use of the most recent editions of the standards indicated below. Information on currently valid national and international standards can be obtained from the Uganda National Bureau of Standards.
For the purpose of this Standard the following definitions apply.
Acceptable: In relation to the certification mark and to consignment inspections carried out by and acceptable to the National Bureau of Standards.
Additive: An oil-soluble chemical compound added to base oil to improve its performance characteristics.
1The engine lubricating oil shall consist of approved petroleum products, or of approved synthetically prepared products, or of a combination of these two types of products, compounded, in all cases, with such functional additives (detergents, dispersants, oxidation inhibitors, corrosion inhibitors, etc.) as are necessary to enable it to meet the other requirements of the standard. It shall be free from suspended matter, sediment, water, and other impurities and,
When so required by the purchaser, the ash content or the phosphorus content or both shall not exceed the value agreed upon between supplier and purchaser.
Automotive engine oils are classified in two general groups by API. Those designated with
These groups are further divided into categories with intended service application as indicated below
SF - 1980 – 1989 US petrol engine warranty maintenance service for petrol engines in passenger cars and some trucks. Oils developed for this service provide increased oxidation stability and improved anti-wear performance relative to oils which meet the maximum requirements for API Service Category SE. These oils also provide protection against engine deposits, rust, sludge, wear and corrosion. Oils meeting API Service Category SF may be used wherever API Service Categories SE, SD, or SC are recommended.
SG – Service typical of gasoline engines in passenger cars, vans and light duty trucks, beginning with the 1989 models operating under manufacturers’ recommended maintenance procedures. Oils developed for API Service Classification SG provided control of sludge and varnish, oil oxidation and engine wear relative to engine oils developed for previous categories. These oils also provide protection against rust and corrosion. Oils meeting API Service category SG may be used when API categories SF, SE, and earlier categories are recommended.
These oils meet the performance requirements measured in the following gasoline and diesel engine tests:
SH for 1994 Gasoline Engine Warranty Maintenance Service
Service typical of gasoline engines in current and earlier passenger car, van and light truck operation under vehicle manufacturers’ recommended maintenace procedures. Oils in this category were first available in 1994, and they exceed the minimum performance requirements of API service category SG in the areas of deposit control, oil oxidation, wear, rust and corrosion. Engine oils meeting API service category SH have been tested in accordance with the Chemical Manufacturers Association (CMA) Code of practice and may be used where API Service Category SG and earlier categories have been recommended.
SJ for 1996 Gasoline Engine Warranty Maintenance Service
Service typical of Gasoline engines in current and earlier passenger car, van, and light truck operation under vehicle manufacturers’ recommended maintenace procedures. Oils of this category exceed the minimum performance requirements of API service category SH with a slightly different simulated distillation and evaporation loss, plus meeting the requirements of bench tests for wet filterability, gelation index, high temperature foaming, and high temperature deposits. API service Category SJ also introduced a limit on phosphorus content of 0.01 mass %. API Service category SJ may be used where API SH, SG, and earlier categories have been recommended.
CD - Severe duty diesel engine service
1955 – 1987 Service typical of certain naturally aspirated, turbo-charged or supercharged diesel engines in high-speed, high-output duty requiring highly effective control of wear and deposits. These oils provide protection against bearing corrosion and high-temperature deposits in supercharged diesel engines when using fuels of a wide quality range.
CE - Oil meeting the performance requirements described in category CD by the 1G2 and L-38 tests, plus the Macks Trucks, Inc. T-6 tests (1984) and the Cummins engine Co. PTC-400 (1983) to address oil consumption, deposits, wear and oil thickening. Provides turbocharged, direct injection diesel performance.
CF for Severe-Duty Diesel Engine Service (Two and Four Stroke-Cycle)
Service typical of certain high-speed, turbocharged and supercharged, two and four- stroke-cycle diesel engines since 1990. API Service category CF oils exceed the requirements of the API service category CE, and provide improved control of oil consumption and engine deposits. Oils meeting API Service Category CF may be used when API Service Categories CE and CD are recommended for diesel engines.
CG for Severe-Duty Two and Four Stroke-Cycle Diesel Engine Service
API Service category describes oils for use in high speed, two and four-stroke-cycle diesel engines used in both heavy-duty, on –highway (0.05% weight sulphur fuel) and off-highway (less than 0.5% weight sulphur fuel) applications. These oils provide effective control over high temperature piston deposits, wear, corrosion, foaming, oxidation stability and soot accumulation. These oils may also be used in engines requiring API Service category CF, CE and CD.
All engine oils shall satisfy the requirements specified in the table 2 below

(Informative)
The following classification do not meet the requirements of this standard.
Service typical of engines operated under such mild conditions that the protection afforded by compounded oils is not required. This classification has no performance requirements. These oils should not be used in any engine unless specifically recommended by the equipment manufacturer. This oil contains no additives, except that it may contain foam depressants
Service typical of engines operated under such mild conditions that only minimum protection afforded by compounded oils is desired. Oils designed for this service have been used since the 1930’s and provide only anti-scuff capability, resistance to oil oxidation, and bearing corrosion. They should not be used in any engine unless specifically recommended by the equipment manufacturer.
Service typical of petrol engines in 1964 - 1967 models of passenger cars and trucks operating under engine manufacturers’ warranties in effect during those model years. Oils designed for this service provide control of high-and low-temperature deposits, wear, rust and corrosion in petrol engines.
Service typical of petrol engines in 1968 - 1970 models of passenger cars and some trucks operating under engine manufacturers’ warranties in effect during those model years. May also apply to certain 1971 or later models (or both), as specified (or recommended) in the
6owners’ manuals. Oils designed for this service provide more protection against high-and low-temperature engine deposits, wear, rust, and corrosion in petrol engines than oils which are satisfactory for API Engine Service Classification SC, and may be used when this classification is recommended.
Service typical of petrol engines in passenger cars and some trucks beginning with 1972 and certain 1971 models operating under engine manufacturers’ warranties. Oils designed for this service provide more protection against oil oxidation, high-temperature engine deposits, rust, and corrosion in petrol engines than oils which are satisfactory for API Petrol Engine Warranty Maintenance Classification SD or SC, and may be used when either of these classifications is recommended.
Service typical of diesel engines operated in mild to moderate duty with high quality fuels. Has occasionally included petrol engines in mild service. Oils designed for this service were widely used in the late 1940’s and 1950’s. These oils provide protection against bearing corrosion and high-temperature deposits in normally aspirated diesel engines when using fuels of such quality that they impose no unusual requirements for wear and deposit protection.
Service typical of diesel engines operated in mild to moderate duty, but with lower quality fuels, which necessitate more protection against wear and deposits. Has occasionally included petrol engines in mild service. Oils designed for this service were introduced in 1949. Such oils provide necessary protection against bearing corrosion and high-temperature deposits in normally aspirated diesel engines with higher sulphur fuels.
Service typical of certain naturally aspirated, turbocharged or supercharged diesel engines operated in moderate to severe duty, and has included certain heavy duty petrol engines. Oils designed for this service were introduced in 1961 and used in many trucks and in industrial and construction equipment and farm tractors. These oils provide protection against high-temperature deposits in lightly supercharged diesel engines and also against rust, corrosion, and low-temperature deposits in petrol engines.
