Had a chance of taking my Toyota Passo for a long trip to Shorkot cantt. My car was imported by me with the help of Usman Bhai. It has just 1897 Km on the ODO meter at the start of the trip (1700km when imported). It was giving me 14-15km / Litre on normal fuel. Before the start of the trip, i went to Shell Petrol Pump on punch-sarki Saddar, Rawalpindi and got the fuel tank completely filled with normal petrol. I have heard about the good quality of fuel there. When I started the trip, i felt considerable loss of pick. The car had 65% of the original pick and felt heavy on the paddle. I knew at the moment that the fuel has issues. From Pindi - shorkot cantt the total distance was 400 km. The mileage i got was 11.7Km/Liter @ 130km/h. I was stunned.
During my stay at the shorkot, i kept making up hypothesis and rejecting them as to why the mileage was so bad. I checked oil, filters, tyres and every thing was fine. So i decided to try another fuel brand. I consumed all the fuel before starting my return journey and filled the tank up from Hascol Pump. I can feel the improvement in the pick of the car. When i reached home, the reading on the techometer shows an average of 16.5km/L @ 135km/h. It was quite acceptable.
At the end of the day i presume that the quality of the fuel at shell punch-sarki pump has either decreased or my car does not like shell fuel. In any case, i am not going to fill up my car from that fuel pump again.
