04 Cummins - 20K miles on Delvac 1

Lightman · Feb 2, 2005

This is 20,000 miles on an 04 Ram Cummins with 40k miles on the clock, Amsoil dual remote bypass system. This was from 20-40k, and I changed the full flow filter and sampled at 10k. The results were fantastic, and are viewable in this forum, I posted them a while back. Anyway these results have slightly higher numbers as expected with 10K more miles on the oil, but I still think they are pretty good. I added no makeup oil, and this run includes a 3000 mile road trip I took with 8700lbs behind me.

Good numbers.

Even the iron seems better than that oil usually delivers.

Were these winter miles?

Lightman · Feb 2, 2005

Sorry forgot the dates. The oil was in the truck from 10-27 to Jan 29.

I don't think I've ever seen Delvac 1 thin to 13.4 cSt before.

Tim - have you seen a lot of D1 results? My first two tests revealed 13.77 and 13.76.

Lightman, I believe that I read in another forum that you had put Mobil 1 Truck & SUV oil in your truck several months ago. Have you since changed it to Delvac 1?

Lightman · Feb 3, 2005

Billmac - I've been on and off with both. I was also told by a mobil employee that they are in fact identical products..

Here is what I found on some new oils.

The Cat DEO Synthetic and the Trk/SUV have slightly different levels. I would want to run a couple more to verify these results (make sure they weren't diluted with another oil) before I made any conclusions.

Aside from the truck/suv vs d1 discussion, since they are very close if not identical - how do you think the oil did after 20k miles?

Stinky Peterson · Feb 4, 2005

Hi Lightman

I think it looks good, I myself would keep running it, and maybe take another sample in about 5,000. See what that looks like before you change. I don't think 30-35K miles would be unreasonable but you need to keep an eye on it.

Someone mentioned viscosity, of 162 samples for 5W40 oils, 40 were below 13.4 cSt. I would not be concerned about your reading.

Good luck

Stinky Peterson · Feb 4, 2005

Rugerman, how did you do that? I spent 1/2 an hour formatting and putting tabs in and then they were gone when I posted it.

Lightman,

Considering the effort you put in the filtration system my first reaction is to not be impressed with these results. Visc100C at 13.4? As mentioned its very rare for Delvac 1 to shear down. I suppose the engine is still breaking in, or the newer engines aren't as nice as my old 1990 B5.9.

My 1990 B5.9 with nothing more than a Wix, LuberFiner, or Fleetguard paper filters and Chevron 5w-40 (Group III) at 200 hours turned in extremely low wear numbers even after a winter of cold starts where the truck was used to drive 20 miles to work.

Even shearing to 13.4, it's still well within 40 grade range. I ran the Delvac 1 fill in my '98 Dodge/Cummins last year to 17K miles, and the viscosity @100C was 13.8cST.

It does seem, though, the newest generation of the 6BT 5.9L Cummins is a little harder on the oil, than the earlier ones were. But still good numbers.

All I can say is consider how much more power my engine is making compared to your 1990. I'm making 380hp at wheels.

Also what effort are you talking about? The bypass system was simple to bolt on.

It would be interesting to see how Delo 400 would do with the filtering setup you have.
