Shell Helix Diesel Ultra 5W-40
Shell Helix Ultra 5W-40
Shell Helix HX7 C 5W-40
All this oils are for diesels too.
And which one is OK for Pathfinder 2.5 Dci 126kW ?
I'd go with the Mobil 1 synthetic 5W-40.
I don't have the diesel manual here in the US to see what it says, but if either 5W-30 or 5W-40 is acceptable and it's not unusually cold wherever you are I stick with higher viscocity.
Helix is a good product too though...I don't think you could go wrong with "diesel ultra" if that's easier to get.
