Blackstone oil analysis for EcoDiesel

I'm about to change my oil this weekend for the first time. I'm only at ~4,100 miles, but due to the firmware bug I only have 6% oil life remaining. I'll get the flash patch later this month.

My question is: which tests should I order? For example, because this is a diesel with a PCV, should I be ordering "Oil + % Ash" as well? Long term coking of the turbo, etc, might be an issue and I don't have a catch can yet. I'm planning to keep this vehicle for many years, and I think that caring for it—starting now—is the best way to ensure long-term reliability.

So, what else? TBN?

Re: Blackstone oil analysis for EcoDiesel

I am not the chemistry guy (nearly failed in High School), so I am here because I am interested, not because I know tons about oil.

Super idea though, Thanks.

Re: Blackstone oil analysis for EcoDiesel

TBN is the most important test you can have Blackstone run and it costs extra but at least for the first one I plan to add that to mine.
The other numbers are expected to be higher than normal just so you know because of engine break in. Blackstone will tell you that but the quantity of oil protectants (more than just a higher pH additive (potassium hydroxide) which Wiki states) which is what Total Base Number (TBN) means is the important one because Blackstone should tell you that you changed it at the correct time or you could go XXXXX miles before changing next time.

I will be doing mine but not as soon as I hoped since I will soon be leaving mine in the garage on a Deltran battery tender for the summer...

Please post your results. I will be posting mine once I get mine done. That should help all of us know how good or bad the algorithm is Jeep uses (actually should help Jeep too since they will see these reports)...

I was planning to do so. I think it might be useful to collect some additional data, such as engine hours (total and since last oil change). I know other people have this data on their WK2's, but I'm not sure how to get it.

Can anyone think of other useful metadata for the report? Right now I am thinking: mileage, mileage since last change, days since last change, engine hours (total/since last change), and percentage oil life remaining on EVIC.

These metadata would give a relative comparison for others. For example, since I do mostly in-city driving I probably have a higher than normal number of engine hours for the mileage I have.

Re: Blackstone oil analysis for EcoDiesel

Two significant factors is climate you live in and the nominal amount of time used per day. For example I live in Florida in the late fall, winter and spring and Ohio late spring and summer. Temps are almost never below 50F. Typical commute for me is a mix of 5 minutes a few times a week to 45 minutes a few times a week at highway speeds.

Not exactly ecodiesel generation but worth looking at....

Vehicle Milage 70,000km

The results and the commentary all look quite positive so am quite happy with how the M1 ESP is performing. I was not previously an M1 fan but am now quite content with the ESP after seeing these results.

That's a great data point. As I suspected—and fun2drive explained—ordering the additional TBN test makes sense.

The only question is whether the "Oil + %Ash" test is worth doing once or twice. It's an expensive additional test. We use low-ash oil; the question is whether this would be a rating of the quality of our oil or if it would be an indicator of wear due to accumulation of "crap" (this is pure speculation on my part).

Basically, ash in the DPF is incombustible/cannot burn off during a regen, unlike soot (the normal combustion particulates) which will. Ash from your engine oil is not your friend and can kill your DPF, so it's critical to adhere to the engine oil specifications for our vehicles.

Looks like your oil ignites a bit too quickly. What was your oil spec?

No idea. You would have to ask Chrysler what they put into the engine at the factory.

Re: Blackstone oil analysis for EcoDiesel

The states (viscosity, flash point) on his Blackstone analysis is pretty darn good. The following linky is to the Shell MSDS sheet for the Pennzoil Ultra Euro L 5w30, which Chrysler uses (and recommends) in our VM Motori engines :

I sure hope that isn't what they use.
" Also suitable for turbo-charged and inter-cooled direct injection high performance diesel engines fitted with 'blow-by' recirculation and exhaust gas recirculation without particulate filters. "

Without particulate filters...... pretty sure our Jeeps have them.
