The Ministry of Commerce and Industry said that the ministerial decision about the Omani standard specification of unleaded petrol will come into effect from July 21, taking into account the Gulf Standardization Organization's (GSO) standard for unleaded petrol.

The announcement about the implementation of this decision was made on January 20.

In a press release, Hiba bint Yasir bin Saud al Mazrouiya, a chemical product specification expert in the Directorate General of Standards and Metrology, said that these standard specifications detail the requirements for unleaded petrol for engines designed to operate with such fuel.

'The unleaded petrol is classified according to the octane number to excellent, which has octane 95 and normal petrol which has octane 91. High octane petrol can also be produced up to 98,' she said.

The standard specifications for unleaded petrol was approved by the ministerial order No 205/2018, which was prepared to upgrade the local technical specifications of petrol, as well as to meet the requirements of the new vehicle models launched in 2018.

Hiba said that the international specifications were to keep pace with the continuous upgradation of petrol, which took place between 2004 and 2012 to improve the quality of petrol. 'There is no doubt that the Omani standard specifications of unleaded petrol matched with Euro 5, especially in terms of the proportion of sulphur that is supposed to be in petrol.'

Hiba said that the standard specifications included the complementary references to the methods of testing, which helps in indicating the correct proportions of the components of petrol. 'There are international references accredited by international and regional organisations. The specification also talks about the chemical and physical requirements of petrol such as the limits of octane number and allowed limits of heavy metals such as lead, manganese, sulphur, iron etc. It also talks about other requirements such as colour, evaporation pressure and corrosion rate of copper.'
