Petrol is a component having high energy of combustion. The product is produced from naphtha a raw material to produce gasoline, Industrial Technologies Program (2006). In terms of PSQCA (Pakistan standard of quality control authority) it is known as Premium (unleaded) Motor Gasoline (PMG). The product is use in electricity generators, two wheelers, three wheelers (auto rickshaw), motor cars and heavy vehicles all around the country.

The specification for research octane number (RON) of gasoline was revised from 87 RON to 92 RON during financial year 2016-17.
