M91 petrol to be officially launched in Oman

Muscat: A new type of petrol, with an octane level between the existing M90 and M95 varieties, will be officially launched by the Ministry of Oil and Gas in Oman on Sunday.
The M91 fuel is being launched to replace the existing M90 which will be withdrawn. The ministry had earlier announced that M91 would be available in the market from early August. However, the launch was deferred due to technical reasons, the ministry had said.
