Does anyone know the lifespan of diesel fuel? I have approx 50 litres of Shell Diesel in my garage but it is over 2 years old. Does this fuel deteriorate or harm a diesel engine in any way? I have a tdci Mondeo *sorry no Mondeo NG* so hopefully the Focus tdci users in the group will see we are brothers after all! T I A. Howie
