Went to garage to fill up with diesel for 200mile trip towing a caravan the next morning. Stupidly I put 3ltrs of petrol in before I noticed my mistake.Then in a panic I filled the tank with diesel. Drove 2 miles home then did some internet research and found good advice on the Fuel fixer website. Phoned them and the lady I spoke to was sympathetic to my problem and I decided to go ahead and arrange for an engineer to visit. Called a 2000hrs, engineer arrived at 2120hrs as advised. Job done in 45 minutes. The engineer was polite, efficient, familiar with my car's fuel system and very competently completed the job, leaving me with 20ltrs of fresh diesel in the tank. Overall I can't praise the service enough.
