Maybe viscosity and insolubles are a loose proxy for head buildup? I'm not an expert on this. I don't know if the oil ever even flows in that area.

Re: Blackstone oil analysis for EcoDiesel

These are the results of a 9910 mile oil change at around 36K miles. The remarkable thing is the TBN of 3.5 which is what some new oils have. That means that there was significant high pH left to combat acid build up and this oil could have gone a lot farther.

As a disclosure this Jeep is operated on the panhandle of Florida and not subject to temps below freezing and the majority of the time driven at speeds about 45 mph.

Do you have a clearer copy? I can barely make out most of it.

Re: Blackstone oil analysis for EcoDiesel

Another EcoDiesel oil analysis for comparison. approx 30k miles on the engine and approx 10k miles on the oil.

First oil change and analysis. Mine was about 95% highway driving and some dusty gravel roads. Using aFe ProGuard 7 drop-in oiled filter. No other powertrain mods. No towing, but lots of trips near max payload.

I'm watching my silver number closely since it is higher than others I've seen and it can be a telltale sign of early oil cooler failure (solder degrading because of bad interaction with coolant), which has been an issue on some of the RAM 1500 Ecodiesels. I've also seen a small amount of brown sludge on the inside of my coolant overflow tank. Could be normal, but time will tell.
Here's my second oil change and analysis. This time it's Mobil 1 ESP 5W30. The high flash point was notable and one of the reasons I chose this oil.

Iron was still a tad high, but not out of the ordinary for a second oil change. Still in the wear-in wash-out phase.

For what it's worth, my coolant tank has been normal. No more sludge besides that small amount when the engine was new. Still some silver in the report, but it came down slightly.

A note on my oil filter. With this change, it was the aFe ProGard D2. Insolubles were exactly the same as the first change that had the factory filter. I got a 4 pack of them from Amazon for about $60 recently, so they can be economical.

Still the same air filter. I just tap out the bugs/grass/seeds every 10K miles. When I get to 30K miles, I'll wash and re-oil the filter per aFe's instructions.

Still lots of highway driving with some light off-road.

I stayed with the Mobil 1 ESP 5W30 since I still had some on the shelf and it looks like this oil analysis supports that decision. Maybe I'll switch to the new 5W40 standard when FCA figures out what they want for the pre-2016 model years. I'm hearing about shorter oil change intervals with the 5W40 in the 2016 model year, which wouldn't make me happy.

And there is nothing to say you can't stick with Euro L 5W-30 indefinitely. There has been no real evidence that it is incorrect/damaging to any 3.0 CRD. ( If there is ..let's see it FCA...) Blackstone proves that the only real benefit of rotella (Although it is a fine oil...) is it is less expensive. Also no evidence of dealers charging any less for using cheaper oil in CRD oil changes....

It does have higher Zinc content which some say is better for the turbo. I would hate to see the bill on a turbo replacement.

Re: Blackstone oil analysis for EcoDiesel

Mobil Delvac 1 ESP 5w40 is the new CK-4 oil that I believe will be the EcoDiesel option from Mobil 1. Rotella T6 is supposed to get CK-4 ratings right about now as well, but M1 has the details of all the improvements CK-4 will bring to the table. CJ-4 is superseded by CK-4, and CK-4 will be all that is available going forward. M1 says this new Delvac 1 ESP 5w40 has a 12.1 total base.
