Cutting-edge fuel certification technology

 

Fuel quality control

Coral implements a full fuel quality control system at all its retail stations through:

Daily unannounced checks by the 4 specially-equipped Mobile Quality and Quantity Control Units.

The addition of a specific molecular marker to its differentiated fuels.

The company's 4 specially-equipped mobile crews have been performing checks daily since 1999.

The aim of the quality control system is to better protect your interests as a consumer and to ensure the highest level of protection, and excellent performance, of your engine.

Our teams operating the 4 specially-equipped Mobile Quality and Quantity Control Units have been performing daily unannounced checks on the entire network of Shell retail stations in Greece since 1999. Each year we cover more than 100,000 km carrying out over 2,000 checks on retail stations to ensure that:

There is no humidity in the tanks and fuel pumps at Shell retail stations

There is no dirt, or other foreign matter/impurities in the tanks and fuel pumps

 

Fuel quality control

There is no mixing of different petrol (e.g. presence of 95-octane unleaded petrol in a tank containing 100-octane unleaded petrol) and diesel grades in our retail stations' tanks.

Checks performed by Shell retail stations include:

  • Determination of fuel density
  • Determination of government-added fuel markers
  • Determination of the RON rating in petrol using Mid-IR analyzers, a methodology similar to the one used by the government’s fuel handling and storage control teams (KEDAK)
  • Detection of additives in all differentiated products (FuelSave, V-Power)
  • Sampling and full analyses in the company's state-of-the-art Laboratories *(if additional checks are required)

 

Driven by our passion we are constantly striving to develop and improve our fuels; this is why we introduced a unique molecular marker technology for their quality control.

All Shell´s differentiated fuels now incorporate the new molecular marker technology which makes it possible to verify the identity of the product and its unique characteristics.

The molecular marker is added to Shell fuels in minute quantities (mg/m3 or ppb). It can only be detected by specialised instruments and it cannot be removed or even altered. Consequently, our fuels can be identified with extreme precision.

 The molecular marker:

  • Is added to the fuel in minute quantities and can only be detected by specialised equipment in the company's chemical laboratories and Mobile Quality Control Units.
  • Detects changes in fuel composition with remarkable precision.
  • Can be used in all types of fuel without altering any of its physical or chemical properties and is completely safe and approved for all engines.

Implementation of this molecular marker system further demonstrates our unwavering commitment to offer our customers high-quality, high specification fuels.

 

Fuel Quantity Control

Alongside its quality control, Coral intensely monitors and controls the pumps and fuel stocks at its retail stations to ensure that the correct quantity of fuel is always dispensed to the end consumer.

Unannounced checks for the proper functioning of retail station pumps.

The 4 Mobile Quality and Quantity Control Units perform unannounced checks on the retail stations to ensure that the pumps dispense the correct quantity of fuel by:

  • Performing quantity control at the pump using certified volumetric containers (volumetric provers)
  • Verifying the correct sealing of the fuel pumps (in accordance with the current legislation by the accredited crews for adjustment/sealing of pumps) and
  • Verifying that the retail stations' control instruments (volumetric provers) are suitable for use.
Fuel Quantity Control

Through the input-output system installed in ALL Shell-branded retail stations (in accordance with the applicable legislation).

The input-output system permits constant monitoring of all pump transactions for comparison with the fuel tank stocks. Any deviation in the quantity, exceeding the permitted limits, automatically activates an alarm with notification to the Ministry.

By a special control team that performs unannounced checks on stocks at the company's retail stations.

The state-of-the-art Smart Ring is a cutting-edge method for electronic quantity control of fuel supply to homes or vessels. It contains the unique details of the customer and the fuel supply process using Smart Ring technology is designed to prevent any deviations between the quantity of fuel ordered and the actual amount received by the customer. This makes it the most reliable and most technologically advanced system for quantity control upon receipt of a fuel.

Specifically, fuel flow from the tanker to the tank is only permitted when the refuelling nozzle (with its special ring) is inside the inlet of the heating oil tank on which the ring has been installed. When supply is complete, an automated receipt is issued showing the amount recorded by the ring mechanism.
