SINGAPORE- Saudi Aramco has agreed a term contract with Indonesia's Pertamina for the first time to supply gasoline over July to December this year, traders familiar with the matter said on Wednesday.

This would likely be the first time Aramco Trading is supplying term barrels into Indonesia, Asia's largest importer of the motor fuel, the traders said, though this could not immediately be confirmed.

Pertamina and Aramco Trading officials declined to comment.

Aramco Trading will be supplying a total of about 1 million barrels a month of 88-octane and 92-octane gasoline grades, traders said.

It was not immediately clear where Aramco planned to supply the cargoes from but it holds a majority share in S-Oil Corp 010950.KS , South Korea's third-biggest oil refiner.
