Let me share with all the PW visitors that I used to get the Engine Oil Changed from Panj Sarki Petrol Pump for last few years, despite the opposition of many mechanics I practiced the same to ensure that I am getting the genuine engine oil.
Last month I was driving on rawal road and my car started loosing pick, I parked the car on the roadside and found that all the engine oil has been leaked and now engine is running dry. I called the nearby mechanic and he told me that your engine has been seized. The reason: Oil filter was of very poor quality and it got leaked from its seal. Basically I used to purchase the oil filter and air filter from Panj Sarki Petrol Pump Tuck shop which is being practiced by mostly customers.
Now I got car's engine overhauled and found a very reputable lubricant which not only have free home delivery but many outlets for oil changing and to my amusement that the oil quality is much better. I will not name the company because people will consider that I am biased to the lubricant I am using now a days. Although I am using Gaurd Oil Filter which is of good quality.
