I purchased a GIP Diesel fuel in France. Almost immediately my car started playing up, the car went into 'limp home' mode. Power was lost and speed severely restricted. These symptoms remained until the car was filled up with a fresh tank of Esso fuel - when the symptoms virtually disappeared. Clearly I'd been supplied with some VERY inferior fuel. This in itself was bad enough, but it's made worse by AGIP's refusal to respond to communications. Customer services are non-existant!! If you can avoid AGIP at all costs
