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.

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
