Official EcoDiesel Oil and Filter Recommendations

[SIO2GA]

Mobile Delvac is a good oil, it just doesn't meet the Chrysler MS-12991 specification. You can always give it a try, pull a sample, and post your UOA results.

I noticed it wasn't on your list - although amsoil is. I'm curious, can you tell me in what ways does it not meet the specs? Not being snide or facetious, I'd just like to know what areas it is lacking?
Or do you just mean it doesn't have the approval (just like amsoil on your list)?
I can't seem to find the "specs" for Chrysler MS-12991 specification. I can't find the saps levels for pennzoil, either. Since I am not an oil expert its hard to figure things out.
I've done a good bit of searching to find out what the specs for MS-12991 actually are. Same with Pennzoil's sap levels and it seems that neither company has that information available online.
So when you say it "doesn't meet the specs" I'm wondering if you can say exactly what area it doesn't meet?

Here's a 400-hour study comparing Rotella, Mobil, Valvoline, Chevron, and Amsoil. TBN isn't that important anymore for modern oils, so I would ignore that part of the test. But if you look at the bottom chart, you can see that Amsoil and Rotella holds viscosity better than Mobil, but Mobil is still very suitable. Very few people run their trucks for 400 hours. If you look at my last two oil changes, you'll see that my engine logged 148 hours in a 5,586-mile interval.

I run Rotella T6 in the gen 2 engine because it gives excellent UOA results. I run Pennzoil Platinum in the gen 3 engine because it gives good UOA results.

Every oil on the front page, including Amsoil, met the Chrysler MS-12991 specification at the time of posting. If it doesn't have the MS-12991 spec, then I need to know so I can edit the front page. Oil manufacturers can change formulations and auto manufacturers can change specifications, so that's why this can be tricky. Chrysler, for example, changed their oil specification for the gen 3 engine at least 2 - 3 different times since its release.

I'm curious, can you tell me in what ways does it not meet the specs?

You would need to ask a tribologist if you really wanted to know specific details about formulas and what key elements are needed to meet certain specifications.

For whatever reason, FCA (who has a contract with Pennzoil) decided to go with the MS-12991 spec for the gen 3 engine. FCA decided to give the gen 2 engine the MS-10902 spec.

What bothered me is that you said that the oil I asked about "doesn't meet the spec" when I was pretty sure that you didn't know that as a fact. I think the exact Mobile oil is pretty close to the same thing as the Amsoil efm product. Amsoil isn't "approved" with Chrysler and Mobile isn't either. I'm not so sure that Amsoil meets the specs for the Gen 3 ecodiesel - they certainly don't have it in writing on the bottle or in their advertisements.
I have nothing against Amsoil and I've spent a lot of money on Amsoil products in the last year, but it bugs me that you have Amsoil on the list but not the Mobile product and even went as far as to say that the Mobile oil I mentioned "didn't meet the specs". I don't think you should say that if you don't know for sure and can't tell me how or where it doesn't meet the specs.
It is a bewildering topic to me trying to figure out which oil is the best for my truck while at the same time won't jeopardize my warranty and won't cause my particulate filter to fail prematurely. I suspect that Pennzoil doesn't "meet the spec" either, and that's why it doesn't post the sulphated ash content (as far as I can tell).
Going from memory (which is sometimes poor), I think the mobile delvac 1 esp oil has the same sulphated ash content as the Amsoil efm: I think it is 1.0 for both of them if I am remembering correctly.
Engine oil properties are a very complex thing and it can be a struggle to figure out what oil is the best, or even what oil is sufficient for vehicles that have Diesel Particulate filters. So it was upsetting to see you say that Mobile "doesn't meet the specs" when I don't think that you know that for a fact. Lots of people visit this forum and just repeat things they see here so I don't think you should have made that statement.
I've only recently became aware of the Mobile Delvac 1 ESP oil and it seems to be a suitable oil that just might be the best option since it goes on sale for $26 per gallon and is at brick and mortar stores as opposed to ordering like with Amsoil.
So I was hoping to get some feedback on if - and why - it might not be a good option.

I knew that as a fact since we (as a group) spent weeks calling the oil manufacturers and asking these questions.

I'm not so sure that Amsoil meets the specs for the Gen 3 ecodiesel

Amsoil verified that they meet spec.

I suspect that Pennzoil doesn't "meet the spec" either, and that's why it doesn't post the sulphated ash content (as far as I can tell).

Not only does Mopar recommend Pennzoil Platinum, but the spec is written on the bottle.

Sorry, but we did our homework. Mobil doesn't meet spec as verified by Mobil.

I'm waiting for my 2nd sample results back from Blackstone. Using Mobil 1 Turbo Truck 5w40 oil.

I'm looking forward to that report. If you don't want to wait forever, switch to Oil Analyzers. Blackstone can sometimes take up to 3 - 4 weeks!

For my Canadians, canadian tire sell motomaster 5w40 and it meets both requirements. Also it goes on sale for $32 for a 5L jug. Says it's engineered by shell so I can only assume it's good quality for about half the price of penzoil.

My latest oil report from Blackstone. 5864 miles on oil. Total mileage on JT 40,163. Mobil 1 5w-40 Turbo Diesel Truck.

"This report looks a lot like your last, which is good news. A stable wear profile tends to equate to a healthy-wearing engine, even if a metal or two read high compared to averages for the engine type. Aluminum is the metal that's high for this engine, but it's rock steady, so it really doesn't look like a worsening problem. We theorized last time that it could show flux compound, and that may well be the case. It's just a matter of watching the trends at this point, but it doesn't seem like aluminum is anything to lose sleep over at this point. The TBN is a strong 6.8."

My aluminum is 19. Fuel, anti-freeze, and water is zero. The oil is holding up.

What were aluminum & iron ppm?

I switched over to amsoil ms but I haven’t cared enough to do an analysis. I expect aluminum to plummet with the surgery

Good tuning makes a world of difference on the Gen 3 engine. Assuming you have the EOC tune, then your aluminum numbers should be down to about 2 - 3. Amsoil MS is still one of the better oils. HPL and XClean Gen2 are also really good oils. Pennzoil Platinum performs very well, too. It just doesn't hold up to shear as well as the others.

Aluminum was 19. and iron was 23.

Actually, it is an MR Tune EOC the reseller.

Unfortunately, if it’s from black stone , the numbers are going to be way off.

The numbers won't be way off. Blackstone isn't a certified lab, and they lack some testing equipment, but the wear numbers will be fairly close.
