Where did you buy the fuel from? if its somewhere like a cheap independant, serves you right. If you filled up your car, and then went away for a few months and came back to the car, its your fault too. 1. Prove the fuel is contaminated. Its easy to say it is, much harder to prove it. 2. if the fuel is contaminated, ring the oil company, not the petrol station itself. How much access do you think the station franchisee/operator has to the petrol they receive? Answer - None. Oil company is responsible for the fuel people sell on behalf of them. 3. If no one is going to fix the car for you, just fix it yourself. Remove the tank, empty it (environmentally friendly way of course). Clean the tank, fuel lines, rails and injectors. Fill up with good quality high octane fuel.
