Oil and filters once a year.

Cummins requires a milage and/or time limit, but, like Bill, we don't put many miles on our ISL during the year and the coach pretty much sets all year......so we too change oil and filters once a year which is Cummins' time limit.

me too.
or prior to any long trip.

Every 250 Hours if it has a Hobbs meter.

How often should you do an oil change on a diesel engine?

Follow what your engine manual says

IF you have just purchased this unit, and have proof of services. Then your driving has a lot to do with your own service tactics. Weather, dust and highway miles make a lot of difference on engine service. Plus mountains,deserts and such. So get to a dealer and a get a book on that engine.
Find out about it and do not wait for this internet place to say this or that.

I drove for several years 11 western states and Canada. hills and flats, we serviced my truck every 4500 miles and oil was changed every 8000 miles. All filters , that included oil, air and fuel filters.. Remember preventive maintenance is better than emergency repair work.

Not once did I have a break down.
Good luck. and get a book or have it serviced by a pro.

Pretty sure our Cummins ISL oil change interval is 20,000 mi according to the manual.

I do not know the proper miles,time etc. when to change the oil, but we do it once a year or about 5000 miles. I know that it isn't many miles but when the camper just sits with changing temps. I do not want any thing to go bad with the oil. We also change the fuel filters at that time. I figure that oil and filters are cheaper than some kind of breakdown.
Just my opinion
Our engine is a Cummins 325
