The year 1993:
Petrol history - Nova GoricaIn June 1993 Petrol introduced its own brand of motor oil under the name PROTON, which was created in collaboration with the international oil corporation TEXACO. In June 1993, Petrol’s environmental efforts and its endeavours to ensure more efficient operation of vehicle engines resulted in the introduction of the “PLUS 5” additive. In September 1993 vendors at 20 of Petrol’s service stations began to change vehicle motor oil using special equipment for enabling a more environmentally-friendly servicing procedure (MOPO). In December 1993 a new cutting-edge laboratory for the analysis of oil derivatives began to operate at Petrol’s storage facility in Zalog.

Petrol history - BledThe year 1997:
The year 1997 was one of the more successful years in Petrol’s history, with sales exceeding two million tonnes of oil derivatives, of which nearly one tenth was sold in Croatia and Bosnia-Herzegovina. At that time Petrol constructed or fully refurbished as many as 30 facilities, opened a new oil laboratory, and acquired an ISO 9001 certificate. On 4 April 1997 Ljubljana's Cankarjev Dom hosted the founding meeting of Petrol's shareholders. One month later, on 5 May, Petrol’s shares were listed on the A stock quotation at the Ljubljana Stock Exchange.

The year 1998:
In 1998 the company’s management began to draw up a new company development strategy and to plan a comprehensive change of the company’s internal organisation. A further 20 service stations were refurbished, which was accompanied by the opening of Petrol's representation office in Sarajevo. Petrol’s laboratory acquired international accreditation. The volume of sales again exceeded two million tonnes, a good tenth of which was sold abroad.

The year 1999:
The year 1999 brought about the third oil crisis and a period of huge imbalance between domestic fuel prices and corresponding price trends on the global supply market. As a result, Petrol designed and submitted to the Government of the Republic of Slovenia a proposal for a Model for the Formation of Prices of Oil Derivatives, according to which domestic prices were to be promptly adjusted to price trends on the world market. At the same time Petrol formulated a new corporate vision and strategy, which was to serve as the basis of Petrol’s further development, mainly as an international trade company and a national energy company. In 1999 Petrol built 18 new service stations and opened its first three stations in Croatia. Ninety-seven stations were included in the proprietary service stations network. The same year Petrol bought its Slovenian subsidiary from the multinational Shell. In addition, a comprehensive refurbishment of the Zalog storage facility was carried out, which thus became one of the best equipped oil terminals in Europe.
