Description of the programme

Framework and logic of the programme | Description of the programme


The research is organized and performed under the exclusive responsibility of the Fuel and Lubricant Technology Laboratory (FLTL) of the National Technical University of Athens (NTUA), to ensure in all cases the identity of each sample taken from specific fuel stations. Visits are scheduled exclusively by the FLTL of the NTUA and are performed without warning. The testing procedures comply with international standards in all their stages (time and place chosen, sampling method, method of analysis, recording results, etc.) without any involvement by elin or its fuel station owners. The substantial cost incurred for the operation of the above programme is covered exclusively by ELINOIL.



Researchers working for the FLTL of the NTUA are mainly postgraduate students. They pay surprise visits to fuel stations of the elin network and take samples of all types of fuels sold in each station (unleaded petrol, super unleaded petrol, new super petrol, automotive diesel and heating diesel). The fuels are taken from the nozzles of the pumps used in each station, that is, at the very places where consumers get their fuels from.


Chemical tests

The samples taken as described above are tested immediately in the FLTL of the NTUA. Testing is done in accordance with applicable international standard methods (EN, ASTM), and the equipment used complies with recent technological advances.


Frequency and number of checks

Based on a relevant agreement, the FLTL of the National Technical University of Athens performs on average three visits per year per fuel station, and no less than two visits per year in any case, irrespective of how far a fuel station might be situated in Greece. Over 3,000 sampling checks, along with the respective chemical testing, are performed annually on all elin fuel stations.


Presentation of results

The FLTL of the National Technical University of Athens submits semi-annual progress reports regarding the programme, which lay down the results of the checks per area, fuel station and type of fuel.


Non-complying samples

If a sample is considered as “non-complying” based on chemical testing, then the FLTL of the NTUA notifies elin immediately in order to investigate the matter. It then determines whether the quality was compromised during the transport of fuel to the fuel station or at the station, whether it was the result of a random event, a human error or wilful adulteration. In either case, elin takes the necessary measures, including onsite investigation of the problem, immediate replacement of the product, enforcement of a period of close surveillance on the fuel station and the transport operator through successive sampling checks and, if necessary, suspension of the partnership with the station or transport operator in question.


Acceptance of the programme by fuel station owners

Before implementing the Quality Control Programme, elin informed all fuel stations included in its network and allowed its partners to suspend their cooperation with the company, without any other consequences, if they felt that they might be compromised by the continuous checks performed on their stations. This led to an initial cleanup of its network, which now comprises honest businessmen governed by the principles of business integrity. The programme also served as a “filter”, since new fuel station owners that decide to establish a partner with elin after the implementation of the Quality Control Programme make an initial commitment that they will accept the performance of sampling checks on their stations, in accordance with the schedule prepared by the FLTL of the NTUA. In fact, it is an inviolable term of their contract that they will accept any check, at any time, and if they refuse to take part in the programme their partnership with the company will be suspended immediately.

Elin fuel station owners genuinely appreciate the importance of the Quality Control Programme and have asked to be subjected to as many checks as possible during the year, in their desire to have uncontested evidence of the top quality of the fuels they offer to their customers.


Quality Control Certificate

Depending on the results of chemical testing performed in the previous year, the fuel stations whose samples comply with the specifications are awarded a “Quality Control Certificate” for the year in question by the FLTL of the NTUA and ELIN. The certificate is put up at a conspicuous place in the station.


Informing consumers

All fuel stations of the elin network have put up appropriate signs informing consumers about the said programme. Public information in the fuel station is ensured through special posters placed at conspicuous places in the station reading “This fuel station is also monitored” and posters placed in special frames upon the pumps reading “This pump is also monitored”. Furthermore, special information material is distributed to consumers providing them with plenty of useful information.


Additional checks on elin fuel stations

In addition to the above checks, which are part of the Quality Control Programme carried out by the FLTL of the NTUA, elin itself checks each batch of fuel taken over from the refineries, by taking a series of samples and thorough chemical tests at all relevant stages, from the refineries and its facilities, to the tank trucks, the tankers and the tanks of its fuel stations. The said checks, both scheduled and non-scheduled ones, are performed by specialized elin employees and are part of an integrated Fuel Quality Management System.
