Official EcoDiesel Oil and Filter Recommendations

[biodiesel]

Are you running GDE ? Have we seen any further data on the concerning aluminum # from gen 3? I think my qs euro numbers were decent for ~5000 miles.

I'm not running the GDE tune with the 3rd gen EcoDiesel. GDE was working on their tune to minimize fuel dilution. There are not enough high mileage folks taking samples to really make any conclusions about the aluminum wear numbers. Ideally, the aluminum wear numbers will decrease with miles. We also haven't seen any high mileage engines torn down. So, at this point, we aren't exactly sure where the aluminum is coming from.

I have their fuel fix tune just waiting to go in until after I get my pump. I'll run this qs to get sampled as well.

Correct. Amsoil SAE 5W-40 MS (AFL) has held up better than any other oil we've seen. I'm still running Pennzoil because I bought a bunch of it for cheap, but the Amsoil MS holds up better. The Pennzoil Platinum performs just as well, if not slightly better, than the Amsoil EFM.

That's interesting that the Amsoil MS has held up better than the Amsoil FS, given that Amsoil recommends the FS for the Gen 3 EcoDiesel. In what ways has it held up better? Less ash? Less oxidation? Less metals? I'm really curious, since I've been using the Amsoil FS to this point. I also just generally would want to know if a Mid-Saps oil is better for the EcoDiesel than a Full-Saps and why that would be the case. Hot Shots Secret has a Mid-Saps Euro 5W-40 that I don't think has been the subject of much (if any) UOAs in these discussions that could be an attractive option depending on the answer to that.

Amsoil makes their recommendation based on the specs that FCA publishes. Even though MS outperforms FS, Amsoil will stick with FCA's specs. MS holds up better to shear and it has approximately 20% less wear metals. Amsoil FS drops off to the 5W-30 range after about 6,000 miles.

Again, very interesting. Also somewhat counterintuitive. My understanding is that Mid-SAPS have less anti-wear detergents than Full-SAPS, so it's weird that the Amsoil MS would show less wear metals than the FS. Why do you think that is?

Why do you think that is?

I'm not exactly sure. The tribologists could probably tell you. It all boils down to the formulations being used.

We are testing lots of different oils. The top three best performers right now are:

#1 - AMSOIL AFL
#2 - HPL 10W-40
#3 - Ravenol VMO

We've also noticed that the Gen 3 engine takes a long time to break in. It's not uncommon to go through a quart of oil in-between oil changes for the first 15,000 miles. The wear metals don't start to drop until about 60,000 miles.

That makes me feel much better about my oil reports lol. I'm surprised mobile or rotella didn't make the list.

Now I'm thinking about using HSS's Gray Diamond 5W-40 Mid-SAPS Euro oil and throwing some oil analyses results into the mix. The "Mid-SAPS" thing may be a matter of correlation instead of causation, but the results between the Amsoil MS vs the recommended FS are intriguing. The HSS oil is infused with their "FR3," which supposedly reduces wear more than the average detergent in synthetic oils. If it outperforms or is comparable to the Amsoil AFL, maybe that could be a signal as to the correctness of FCA's current full-SAPS recommendation.

I’m about to send my oil for analysis through Horizon oil analyzers (the one you get when you buy Amsoil analysis kit). I’m running the Amsoil MS but can’t find the oil in their database to register the sample. What do you guys use?

looks like they have FS but not MS in their database?

Amsoil MS is product code: AFLQT-EA.

Yeah, it was very alarming at first, especially for those of us who have both the Gen II and Gen III engine. The Gen II has very minimal wear metals and the Gen III has super high wear metals. We're finally starting to get enough high mileage engines to see that wear metals do indeed begin to drop, but not until about 60,000 miles.

The owner's manual talks about oil consumption during the break-in phase, but they didn't say how bad it was. And since I use my 2020 mostly for towing, I saw some serious oil consumption for the first 15,000 miles.

From the samples we've seen, Pennzoil Platinum performs better than Rotella T6. Nobody has tested Mobil, so we don't have any data for their oil.

Let us know if you have samples to post. We have one guy that is currently running Hot Shot's Secret 5W-40, but he hasn't submitted any samples yet.

I still have a 3-year supply of Pennzoil Platinum, so I won't be making any changes anytime soon.

So after reading the many pages on different oils I’m still at a loss on if there’s any real world benefit of paying almost double for the Amsoil MS vs just using the Quaker state Euro and keeping oil change intervals around ever 5k miles?

For a 5K mile change interval, I think you will be wasting your money using the Amsoil.
