Didn’t we already discuss this in detail back in 2019?
Ravenol NDT 5w40. End of discussion...
You very kindly offered advice on my Jeep 3.0crd with the Mercedes unit. My observation/enquiry is for the later VM Motori unit found in the latest Jeep. Totally different engine.
I just found it interesting that FCA in UK decided on a different Oil spec than North America.
I would like to upgrade to the later model Jeep Diesel but after reading a fair amount I am put off by the Engine issues.
Also wonder how DPF friendly the Selenia A3/B4 is. It does not give an ash content.
