I have an 05 Newmar Kountry Star with a Cummins ISC 330 in it. Spartan is telling me 20 quarts pan and filter, Cummins is telling me 24 quarts pan and filter. Which one do I believe? I have called both places 4-5 times so I could talk to different customer service people and they are all telling me the same thing. Should I go 22 quarts and see if I'm still getting blow back on my toad?

Thanks for any help you can give me

Why not go with 20 and then check the dipstick? Of course run it for a couple of minutes before you check.

Check oil level on dipstick before change. Drain oil and measure amount of drained oil plus one quart for filter. Add same amount as drained. Should be same point on dipstick. Some motors like to run a couple quarts low and only experience will tell.

From what I understand the dipsticks are known to be wrong. I just don't understand how Spartan could tell me one thing and Cummins tell me another?

The ISC filter holds 3+ quarts,
and you must fill the filter before you install it.
I have an 08 ISC, and my dipstick shows
full when I put in a total of 21 quarts.
I've been running mine this way for 90,000 miles.
Whatever you put in, after running the engine you
have to wait at least an hour to get an accurate
dipstick reading.
If you have your engine serial number, Cummins might
be able to give you better info. But asking some phone
jockey how much oil an ISC holds can lead to bad answers,
as Cummins made the ISC with several different pan configurations.

I would start out with 20 quarts and then check it. It's easy to add more than taking out some. My 03 Dutch Star with the 350 holds 22 quarts

Maybe the difference is an external oil cooler that Spartan added....

Ooh Mr. Tileman71, you are new and naïve I see. That is all right after reading this forum for a while you will no longer harbor such a simplistic view of things. We can help with that.

Not niave, just trying to figure how much oil to put in my engine. Like I said Cummins says 24 and Spartan says 20. What would you do? Dipstick is not doing me any good with a gallon discrepancy for I believe it is missed marked.

Yup. Put in 20qts, run the engine for a few minutes, shut it down. Now wait for about a half hour for all the oil to drain down.

For many years I would check my oil about 10 minutes after shutdown. I was always about a qt short. Not too many months ago I was reading the engine manual and it mentioned this wait time. I am not really loosing oil. I was blowing the extra out.

I have started using 10w-30 also. It is recommended by Cummins. Blackstone Labs did a piece on viscosity that made sense to me. Lighter oil gets to the vital parts quicker. Last oil test came back very nice.

Happy trails,
Rick
