The government is working to bring Pakistani fuel up to Euro-Five standards, which emit less pollution but may face resistance from oil refineries as they upgrade their plants.

The government has asked oil companies, including PSO, Shell, and Hascol, to import only Euro-5 standard petrol from September 1, 2020, while Euro-5 diesel should be imported from January 1, 2012. PSO has more than 3,500 petrol pumps in the country.

Euro Five fuel is available at Rs 120 per liter, which is about Rs 20 more expensive than regular petrol.

Euro Five standard fuels have the least impact on the environment because they contain 98% less sulfur and 80% less benzene. It reduces vehicle emissions and improves engine performance. Low gasoline fuels do not adversely affect the health of industrial workers.
