The state-run Indian Oil Corporation on Friday said it has tied up with the world's fourth largest oil firm Total of France for the marketing of diesel and petrol additives, and research and development.

The agreements were signed by M S Ramachandran, chairman, IOC; Alain Gremmiliet, director (marketing), Total and Sylvan de Lescaze, director (R&D), Total, a company statement said in New Delhi.

Under the terms of the agreement, IOC will market Total's diesel and petrol additivies under the brand name Servo Adon D for diesel and Servo Adon P for petrol through its countrywide network of retail stations.

These additives are complementary to the premium fuels IOC Premium and Diesel Super, introduced by IOC in almost all the markets earlier this year.

"These additives will enhance vehicle performance through improved fuel efficiency, lower emissions and ensure overall better drive," the company said.

The research collaboration between IOC and Total covers fundamental research in hydrocarbon chemistry, processes, development and use of pilot plants, engine testing facilities, analytical techniques and catalysts.

"The collaboration between the two oil giants will provide a vital thrust to upgrade technologies in refining processes and additives so as to cost-effectively offer best quality fuels and meet the challenges of the new fuel-efficient engine designs and stringent environmental standards," the statement said.
