the question is techincal and will probably not get exact answers that is unles your motor gives trouble and you have to take it to a main dealer for the moodel wererupon they will probably immediatly test the viability of the fuel and find it not up to their spec after which i leave to your imaginnation what happens next ..my advice to people using a ford motor expecially a diesel is to buy popular branded trusted fuels like Esso ..texaco. shell. or other good brand fuel it is not and i repeat not worth the saving of a few pense buying supermarket fuels as they are not determinable in use..as in the last few years in the U.K the debacle regarding fuels and ruined engines.now forgotten by some but firmly in the memories of anybody who purchased these fuels at the time
