Below are UOA results from Blackstone.

2014 JGC EcoDiesel
Oil Type: Rotella T5 10W30
Current Mileage: 7,000
Miles on Oil: 4,000

Added 1/2 can of Liquimoly MOS2, roughly 8 oz.

TBN at 3.8 sounds lower than what I would've expected. 16 PPM iron sounds higher than what I would've expected for 4,000 miles.

Next sample will be, whatever the dealer puts in, which I assume is Euro L, run it for 4,000 miles and I guess to be fair I should put in 8 OZ. MOS2.

Consider this, the sample shows about 50% less wear than seen on other samples. I'm basing that from 16ppm iron vs. 50 ppm iron on other samples (and using 229.51 oils).

Ok trade off, it could end up on your DPF, IF your engine burns oil excessively.

Given this trade off, i'd rather protect the engine than the DPF. Everyone else looks at it the other way around, I just use common sense.

I'm at 23,000 miles, 15,000 of those miles with CJ4 oil, only regenned twice in 23k. Appears my DPF is in good condition.

Mobil1 ESP has around 75 ppm of moly in its additive package.

Why people feel the need to use incorrect viscosity oils which are unspecified by the manufacturer during their warranty period is beyond me:confused:.

Why even go there while under warranty!

At almost 14k miles, I have never seen a regen message. I also do a quick EVIC check on the DEF level and have seen it drop slowly, almost exactly "in time" with the mileage:thumbsup:.
