18-5-2011 is the most shocking day with regard to my car today. I own Ritz diesel. On 12-5-2011 I filled up fuel tank full of diesel from Tulip petrol pump beside Himalaya book depot, Punjagutta, Hyderabad. My car engine started to get noisy and cranky, I took my car to the service centre and got it checked. We found out that the diesel is mixed with kerosene (SHOCKING). The owner of the petrol pump argues with me saying his petrol pump has a reputation and that cant happen. He also was rude in telling me to go anywhere or complaint where ever you want. I had to empty the fuel tank and got diesel filled in one Indian Oil outlet. The knocking sound in the engine still exists and the service people say that it will take atleast 500 to 600 kms so that the car can get to normal condition. Later i came to know that mixing of kerosene and other type of spirits is happening in many outlets. So, be careful guys its all cocktail over there.
