Presentation
The GFC is comprised of four technical committees:
Technical Committee on Lubricants for Thermal Vehicles (CTLVT)
The objectives of the CTLVT are to identify the needs, at the French level, for test procedures for the evaluation of the performance of lubricants used in land vehicles (cars, trucks, tractors, construction,...). , develop, publish, disseminate and monitor these procedures in the areas of:
- Motor lubricants (former CTLM committee)
- Transmission lubricants and greases (former CTLT committee created in 1967)
Technical Committee for Motor Fuels (CTCM)
The CTCM, Technical Committee on Motor Fuels, is the forum for discussion and study of issues relating to fuels and engines of all types within the GFC. Made up of French experts in these technical fields, the CTCM’s main tasks are to share national and European experiences and to manage the sub-working groups attached to it.
Technical Committee on Other Fluids (CTAF)
The Technical Committee of Other Fluids (CTAF) was created in 1991 to be integrated into the CEC first as FSG (Fluids Special Group) in 1996 within the framework of the CEC’s committees (ECTC Engine Coolants Technical Committee). Following the meeting of 20 April 2001 in Paris, it becomes a technical committee of the GFC with the same active members: French, Italian, Spanish, English and German. He is currently mainly focused on coolants, but has in the past worked on brake fluids and vehicle cleaning products
Electrified Vehicles Technical Committee (CTVE)
The Electrified Vehicles Technical Committee (CTVE), created in 2022, brings together the growing activities on electrification initially carried out by members of the CTAF and the CTLT; The objective is to identify, develop, publish, or develop test methods for current and new lubricant and heat transfer fluids in hybrid and electric vehicle applications, to disseminate and monitor
Several working groups are already open on the aspects of corrosion, presence and consequences of water, electrical properties, lubrication/wear.

Technical Committee of Transmission Lubricants
Introduction TO BE UPDATED
Technical committee of Transmission Lubricants ( CTLT) The CTLT, Technical Committee Transmissions Lubricants, is the French equivalent of the former TLTC (Transmission Lubricants Technical Committee) of the CEC. It was created from 1967 and is interested in lubricants necessary for the transmissions of the ground vehicles (automobiles, heavy trucks, tractors, machines of construction site); It is worth to notice that it works also on greases.
Technical Committee of Engine Lubricants
Presentation TO BE UPDATED
Le CTLM
The CTLM, Technical Committee of Engine Lubricants, is one of the four Technical Committees of the GFC, the activity of which focuses on the evaluation of the performances of the lubricants for internal combustion engines.
The history of the CTLM dates back to the origins of the GFC in 1963.
The GFC was the French equivalent of the CEC-ELTC (Engine Lubricant Technical Committee) until the profound reorganization of the CEC in 2001.
CTLM members
The CTLM brings together GFC member companies and has 18 members in 2018.
- Automotive and equipment industry
- Oil companies, lubricating industry and additives manufacturers
- Testing laboratories, Engine or petroleum product users
The main missions of the CTLM
- Allow technical exchanges between manufacturers, the oil industry, additive manufacturers and users
- Identify the need for test procedures for the evaluation of the performances of engine lubricants and for the characterization of engine lubricants

Activities
THE USEFULLNESS OF CTCM
The CTCM tests methods created by the CTCM are tools reliable and regularly used by the industry to evaluate the performance of fuels for internal combustion engines.
They were created in the continuing effort to offer to the end user - the motorist - quality products, validated by a set of tests standardized, relevant, reliable and recognized by all the oil and automobile industry.
The main methods used to evaluate the influence of the quality of fuels or additives on the performance of the engines. So the GFC-CTCM catalogue offers test methods aimed at reproducing the following phenomena:
- clogging of injectors and other components,
- oxidation phenomena,
- wear of some mechanical parts ( injection pump…),
- driveability, cold or hot, of gasoline or diesel vehicles.
THE BIRTH OF A TEST METHOD
The creation of a test method is primarily motivated by the aim of reproducing - at a lower cost-, a phenomenon identified or potential on engine in service. This may be necessary as a result of a problem observed in use, or during the development of new engine technologies, which we want to assess the sensitivity to the properties and the quality of fuels.
A working group, said investigative, can therefore be established to document the problem, make a synthesis and assess the need for the creation of a specific test method. Where this need would be clearly established, When the test method is no longer used or becomes obsolete, it loses the official recognition of the GFC. The group becomes a project group, which is entrusted with the role of development of the test method to reproduce the phenomenon.
The final product of the Working Group is a ready to use test method, validated by inter-laboratory tests, which have demonstrated the statistical validity (discrimination, repeatability, reproducibility) of the results obtained.
After validation of this method, the Group becomes a monitoring group, and is responsible for the organization of regular round robin tests, in order to follow closely, during the lifetime of the method, its characteristics of accuracy and relevance.
It is also this monitoring group that can organize campaigns of exploitation of the method e.g. operating to characterize a market or to decide on the obsolescence of a method and its withdrawal (availability of parts, loss of representativeness…).
THE DEVELOPMENT OF A TEST METHOD
When the first version of the test method is finalized and the circular test campaign is ready to be engaged, the method is known as experimental, and it receives the "X" status. When this campaign is concluded and if the results were good in quality and acceptable in precision, the method is said Tentative, and receives the "T". The status 'A', as approved, is obtained only after circular tests showing a good reproducibility, defined with the participation of statisticians from the GFC.
When the test method is no longer used or becomes obsolete, it loses the official recognition of the GFC.
Methods
The most recent work of the CTCM focused on the following themes:
- Diesel fuels lubricity: Applicability and reproducibility of the HFRR method.
- Characterization of the stability of present diesel fuels at low temperature: Forum for the exchange of customer complaints and changes observed in terms of fuel quality. A study on long term storage is launched.
- Guide to good practices for the control and treatment of contamination by microorganisms: The document is issued as GFC-CA-46-A-15 and available (see « methods » in the website)
- Characterization of the effectiveness of anti oxidants additives: A new methodology for determining the position of an anti oxidant additive compared to another and to BHT additive has been created ; this method GFC-CA-42-X-11 is being finalized and will be soon available.
- Impact of the volatility of gasoline on the cold and hot driveability of vehicles: Those works were recently included in a comprehensive study (more than 250 tests vehicles on chassis dynamometer) realized with CONCAWE (CONservation of Clean Air and Water in Europe), consortium for environmental studies related to the oil industry.
- Evaluation of the cold start of diesel vehicles: The constraints of pollutant emissions reduction associated with the necessary reduction of fuel consumption cause an increase in the problem of the cold start. A methodology related to this issue was created under reference GFC CA-39-T-13. This methodology is proposed in the European commission H2020 consortium.
- At each meeting a place reserved to discuss market issues and fuels qualities primarily in Europe.
Technical Committee of the Other Fluids
Presentation
Chairman: interim Claude DELARUE (GFC)
Vice chairman : M. Ralf Strauss (BASF-D)
Since 1980, a working group of the GFC in the CTLM (engines lubricants technical committee), has developed methods of testing the cooling liquids. A collection was published in 1990: GFC-L-100-A-90, “coolant for Internal-Combustion engines”, containing 8 methods at the "approved" status. Their repeatability and reproducibility is perfectly defined, these methods were transmitted to the BNA (Automotive standardization office in AFNOR) and contributed greatly to the development of the first French standard on the cooling liquids: NF-R-15-601.
In 1991, the technical Committee on other fluids was created and took over the activity of the Working Group of the CTLM by expanding beyond the cooling liquids. Integrated in 1996 within the CEC as Fluids Special Group (FSG), the CTAF continued its work in the context of the ECTC (Engine Coolants Technical Committee) until 2001. Following the meeting of 20 April 2001, the ECTC had no longer enough dynamics to continue its work within the new CEC and the group returned to the GFC in retaining its European members (French, German, Belgian, Spanish, English,...).
Today, the CTAF has 15 participants, and its members meet 2-3 times a year. This number is growing since 2001, and the CTAF remains a working group with a European vocation. The CTAF activity focuses on the cooling liquids. To date, some of the methods of 1990 have already been reworked, and others will be revised soon. In addition new methods, initiated from the work of the GFC.
Activités
The CTAF has several missions within the GFC; these are mainly:
- Create or develop, on the theme of automotive fluids (excluding oils, greases and fuels), French testing methods, which may be introduced at European level.
- Enable, through regular contacts, technical discussions between manufacturers, chemical industries, fluid manufacturers and users.
- Promote methods validated with the standardisation bodies (AFNOR, BNA,...).
- Ensure the relevance and sustainability of methods validated through the monitoring committees and the periodic revisions.
The main topics are:
- Physico-chemical determination
- Performance Evaluation
- Compatibility testing
- Contribution through BNA to update the AFNOR standard NF-R-15-601 on coolants
