DPF oil for Defender is not easy to find.
I cannot believe that my local dealer will not sell top up or larger volumes of oils for maintenance purposes. It is a commercial vehicle for goodness sake!  It is ridiculous that these specialised oils are not sold by the dealers. You would be lucky to find them in the bush
