What oil to use after DPF delete?

[tcte]

Was wondering what oil i should use after doing a DPF delete and tuner. Wondering what your guys' thoughts were?

I would run the oil your normally would run in it... i like mobil delvac

[Beatngu]

90% here will say Amsoil or Rotella full synthetic

i put the kind that keeps the truck running, aka CI4/CJ4 rated 15w40(in normal temps)... keep it simple..

I've used Motorcraft in all my vehicle's. No complaints.

With the DPF gone you can use a CI-4+ oil now instead of CJ-4. With the DPF you have to use CJ-4 due to the low-sulfated ash content. Without the DPF the CI-4+ oil's offer better protection with the higher sulfated ash content. I would run AMSOIL HDD5W-30 or AME 15W-40. Zink is a good thing and there is more in the CI-4+ oil's.

Depends on if you are planning on ever putting the truck back to stock and taking it in for warranty work.

I would stick with a 15W40 CJ-4 blend at 5k intervals for that reason. I ran Motorcraft the first 2 changes, Rotella on the 3rd, noticed a 4 to 5 degree increase in oil temps with the Rotella, and have a case of Valvoine 15W40 Premium Blue in the garage I am going to try next.
