I put 18 month old petrol into a half full tank in my wifes car. Ths car was running perfectly well before I did this, so I assumed that the fuel was too old and 1 should not have done this. I have home start as well as fuel drainage so I contacted your any for assistance. I can quite easily drain the fuel myself but as I had paid for this service I thought id leave it to your engineer. a guy came round to assist but all I got was him turning over the engine endlessly. fuel was getting through, it did start momentarley but ran lumpy. he than used my diagnostic machine, but this showed no codes. he didn't think it was the old fuel that was causing this to happen, but the injectors may be at fault. I fail to see that this was the answer but agreed to book somebody in who he recommended to get this car started. He then left. I am only pleased that this problem occurred in the middle of no where, because It is not my car, but my wifes.. I expected more from your company but the 'service' she's got is way below your competitors are offering. I just hope that when I get this car functioning I don't have any other breakdowns, because I have had negative results right from the initial phone call to the so called mechanic that came round. this car has done only 20000 miles that's probably the reason you only take younger cars and not ones older. However it seems you cant even get the younger one going.
