Thanks in advance!

You live in California, how frigid does it really get there? Be kind to your engine, that Delvac Extreme full synthetic 15W-40 is great oil and gave you good results. If it aint broke, don't fix it.

What's up with the coolant?

I've never done Wix or other Blackstone type reports so not really familiar with reading the metrics but do the time on unit/time on oil numbers add up for the last submission?

There was a short OCI between with a blend of oils.

Gasket maker from replacing the oil pan. Good question!

Well, as you can see that is snow in the bottom pic. ❄

The other thing I noticed was a 12 quart sump listed. Man, that seems like a lot of oil to be dumping every 4-5k for a 3 liter engine.

Yes, the OEM pan holds 10.5qts. The aftermarket AFE pan brings ot to an even 12qts. I agree, 5k OCI may be overkill but I do this for a hobby and for fun. I feel most comfortable with limiting the OCI to 5k.

With you there 100% on the fun and hobby ...

His soot is ~ 1%, that seems high especially when you consider it's 12 qts and only 5K miles on the oil. This is also CARB diesel which burns pretty clean. I think the updated tune FCA gave the EcoD after the emissions recall isn't that great and it burns dirty. I'd change it early too.

OP can probably cut his soot production by 50-75% by using a diesel fuel additive like Redline catalyst or TDR-FL

Thanks for posting i’ve been using Delvac Extreme in my ecodiesel also.

recently changed the oil cooler too - “proactively”

I'm going to use Delo 600 ADF and see if that helps.

How would that help? Soot is from combustion, not the oil itself.

Can someone help me understand how my sample at 5700 miles with low wear metals, has a viscosity that is uncharacteristic of Delvac?

 

[Sword_of_the_Spirit]

It’s your motor. Not the oil. You said you ran this twice. Same lot or time of purchase for the 4.5l required for each change?

 

[whizbyu]

Yes. Just found out through the TDi forums that Stanadyne contains naphthalene and toluene. OF COURSE I did not read the label of Stanadyne. I'll stop using that additive.

I'm curious. Is the Delvac approved for this application. The oem warranty did not cover the DPF. The Mopar extended warranty did not cover the DPF. The extended warranty they gave us with the emissions settlement gave us 100K if I remember correctly. If the Delvac is not a low SAPS oil, will that affect your warranty?
