no i dont intend to use it before anyone asks
however i suspect the person who owned my tdci fiesta before me did use it
i may be wrong though
however when looking for a coolant leak i thought i had found it near my EGR valve
but on closer inspection the pink/red dried in stains had been due to it dripping onto the egr and parts around it and the only thing above those parts is the fuel filter
also the previous owner stayed on a farm
so i still aint found my coolant leak but i suspect the previous owner was using red diesel and some spilt when they changed the filter at some point
would dried in red diesel leave a dark pink/red stain and be quite powdery ?
