UNIT ID: 08 RAM 2500
OIL REPORT DATE: 9/19/2012
Cummins 6.7L OIL TYPE & GRADE: Valvoline Premium Blue 15W/40
Diesel FUEL TYPE: OIL USE INTERVAL: 10,086 Miles
Oils: VPB /Unit Ave./CTE/VPB/CTE/VPB/CTE/Univ.Ave (Castrol Tection Extra)

COMMENTS: This oil was in use 10,000 miles, but the engine handled it very well indeed. Iron is the only metal noticeably higher than last time, but that metal tracks with time on the oil, so it's not really a concern. Plus, wear metals are looking good compared to universal averages and the other metals stayed low and flat. No fuel or coolant showed up in the oil and air and oil filtration are fine. The TBN was 4.1 showing lots of active additive left; less than 1.0 is low. This engine could honestly handle 12,000 miles on the oil, but 10,000 is working well. Nice report.

What kind of air filter. The silicon is super low.

 

[sikesix]

Just the stock air filter system.

I don't remember seeing that Calcium/Magnesium blend in anything but a synthetic before.

Nice report!

 

[gregnash]

Seems strange that your Zinc/Phosphorous/Boron/Moly numbers are kind of all over the place.

 

[sikesix]

The fluxuation is due to the additive package differences of the two oils. And the spike in Moly (319) & Boron (51) are due to the oil additive I poured in half way through that OCI (see last paragraph).

Valvoline Premium Blue 15W40 is higher in:
Moly, Magnesium, Phosphorous & Zinc

Castrol Tection Extra 15W40 is higher in:
Boron & Calcium

The extreme spike of Moly in the next to the last OCI was due to my adding two 10 oz. cans of LubroMoly MOS2. I did this to add Moly and got the added benefit of an increase in Boron as well. You may notice that the increased Moly even carried over into this current OCI of VPB doubling it's Moly readings.

1) very nice numbers; no reason not to increase the OCIs. 12k is very doable, and even futher not out of the question. There is another memeber here (biggreymegacab IIRC) that has success running this oil in an Cummin out to 18-20k miles, all on dino oil with no bypass filter. These ain't your daddy's engines and oils ...
2) leave out the additives; not needed (waste of money and blurs the UOAs)
3) use the data text block tool, please!
4) this belongs in the UOA forum; I'll move it for you

I wouldn't get too carried away with the moly. It can tend to eat away at the bearings if too much is added. 100pm is plenty to get the wear benefits.

Is this a stock 6.7 cummins or did you delete it ?

I doubt it's stock wear numbers would never be that good.

 

[sikesix]

Good call, it's deleted, but not till 62K.
