get the best you can afford if its a turbo engine.... much les lickly to crack in the turbo and cause the black death! I realy would recomend a good synthetic oil if you have a turbo! and £22 for 5L of 0w-40 diesel oil for is is a good deal! the 40 weight oil is fine for the TD and the 0w part mains better flow when cold. snd any way film strength is what really counts.
