EcoDiesel UOA (Oil Analysis) Results Thread

[Idlethunder]

Just got my first one back on the ecodiesel. Have done a few things to it in the past few days so I'll change the oil again in a couple of weeks.

Here's my first analysis, for background the first change was at 5k and about every 10k after that, the first I did myself with Pennzoil and a factory filter then the next three were Jeep Wave changes with the dealer using Shell Rotella T6 with factory filters. Next two I did myself with Shell Rotella T6 with a Doc's filter then a Carquest Premium filter. So this analysis is Shell Rotella T6 and a Carquest filter with about 5700 miles on the oil. I changed to Castol Edge Euro this change with a ECOGUARD filter, I'm thinking about going 8k this time and see how the Castrol holds up. So what the consensus on my report and with the Rotella T6 being low SAPS should I consider going back?

Here are my Blackstone analysis results for my past six oil changes. I have always used Pennzoil Platinum Euro 5W/40. I have noticed that my viscosity is on the low end or just below where Blackstone says it should be.
Some recent reports from users of Shell Rotella T6 and Amsoil Euro that had better Aluminum and Iron results than I have had, but reports were only for a single change interval. I'll continue to watch for results from them and decide if I want to give one a try. I feel like I have a good sampling of results for the Pennzoil Platinum Euro in my engine by now.

HPL 5W-30 and 10W-40 are the best oils we've seen that hold up well against shear. We've seen up to 18,000-mile intervals with HPL with great results.

Some recent reports from users of Shell Rotella T6 and Amsoil Euro that had better Aluminum and Iron results than I have had, but reports were only for a single change interval.

As for wear numbers, Amsoil MS has been a top performer. It also holds up well in factory tuned engines. I was going through a quart of oil every 2,000 miles of towing with Pennzoil Platinum. I don't have that issue with Amsoil MS.

I noticed that the report showed "tuned". What tune do you run?
My GDE EPA legal tune shows higher fuel dilution than I like.

Yeah, the GDE Afterlife tune is the one to go.

I know. Having to state my mileage when it's not quite where it needs to be to be in compliance is the problem.

I can appreciate your honesty. All three of my Ecodiesels are bone stock and that's because I've followed the federal emissions laws. I live in New Mexico in which I can buy a brand-new truck today and delete it tomorrow; however, that doesn't make it legal to do so.

I'm now at the point in which I can legally run the Afterlife tune on my 2015 Ram EcoDiesel, so I will be purchasing that soon. Unfortunately, I've got long wait before I can put the afterlife tune on my 2020 and 2023.

Even on the 2015, I plan to disable the EGR function only. I will continue to run the other systems (DPF/DEF).

This is my oil monitoring method.. No sense in worrying about mine. Jeep won't warranty the damn thing anyway so might as well drive it unstressed till it blows and keep the 20K under the matress it will take for me to drop in a new crate motor.

I have the same tune, GDE EPA legal since 44,700 miles, so for the last three oil change intervals.

You can do two things at once. It's okay to monitor the condition of the engine and still set aside money for future repairs. I can't speak for everyone, but oil sampling isn't something I do because I'm worried. Oil monitoring gives me the confidence to keep driving my vehicles knowing that there isn't an underlining issue. Actually, I would be more worried if I didn't take oil samples because then I'm not monitoring engine health or detecting potential mechanical issues. The idea is to detect issues before they result in a catastrophic failure.

Yep. It's like never going to doctor for blood work and tests, then suddenly you have to get a million dollar quadruple bypass.
