You should only get filled from large, renowned company operated pumps of Shell, Total and Attock. Their quantity and octane level is good. Avoid PSO and Caltex because they sell poor octane level fuels in same price.
Also try mixing 2,3 liters of Hi octane fuel in it. Maybe GD's engine needs better octane level fuel...something that is very common in developed countries.
Hence try mixing Hi octane and regular in a ratio of 1:3
Hi octane costs 135 Rs but its octane is 93 or 95. Premium unleaded fuel should have ideally 91 octane... which is offered by above stated pumps, however PSO offers 87 octane rating.
Even my CG needs 91 or plus octane otherwise it knocks... its stated in its manual. I also mixed hi octane in its fuel and results were amazing, I have got great milage from my CG.
Im sure its near 50kmpl at least.
