I have been using Penrite HPR5 5w40 Ford M2C913 C/D in a MY11 SDV6 [Non DPF] buy it in 6 litres and a good price at Supercheap $44.89. Noticed Penrite Enviro stated on the 6 litre container that it was suitable for DPF and non DPF...cost nearly twice as much though!Inox and Lanox not bad priced at $12.15 each.
