Traveller for Cummins ISX

[Redland1]

Is Traveller 15w40 a good choice for my 2004 Cummins ISX CM870? It has 450k miles and is new to me.I’m thinking of doing 10-12k OCI’s.Oil filter is a BD7154.

Here is a Traveller thread from a couple years ago. I would think Traveller would work just fine.

Last voa that PQIA did of traveller 15w40 looked pretty good.

Cummins recommends Valvoline Premium Blue. My 6.7L has had nothing but Mobil Delvac since I bought it. Pick an oil that meets or exceeds the manufacturers recommendation and motor on.

Just my $0.02
