Observations from 20 years working on my model is that they guzzle and leak shell and valvoline product even though the specs are essentially the same.

Castrol rx is easy to get and pretty cheap so that's what it'll get.
That is interesting, in the USA Cummins specifically recommends Valvoline Premium Blue 15-w40 oil. All of their preferred oils are Valvoline...
