I can't get the search to work, what oil should I be using?

Cummins says go 15K on oil changes if you're not using CG-4 oil... You have 3 options and even though I'd rather not go with CG-4 to increase my intervals I've read to not use the new oil for the emissions diesels since they don't lube right.

So which is it CI-4, CH-4 or CG-4 that is the new oil they have to use on the 07.5+ trucks?

mobil delvac 1 fully synthetic the best oil in my opinion. Amsoil is also really good

I would go with CI. Doubt you can find CG or CH on the shelves at most places.
Or you can use the new CJ oils.

CI it is then. Why does cummins say reduce your intervals if using CG oils? I'm assuming that is the new oil and doesn't lube properly.

MikeyB, CJ isn't an option on that link I posted above.

CJ+4 is the new oil required on the new '07 emissions equipped engines.
