2023 3.0 Duramax 25k miles; Mobil 1 ESP x2 0W-20 3.4k mile UOA

[fueldelusion]

Attached is my first UOA for my 3.0 Duramax. I usually change the oil closer to 4.5-5k. Changed this earlier as most of these miles are from short trips during a brutally cold winter. Report shows it was unnecessary.

ESP x2 can now easily be found at my Walmart and Walmart online at typical full synthetic Walmart prices so I’m pleased with that. Every jug I empty has additives sitting at the bottom, shaking the bottle makes zero difference. Clearly not an issue.

On every report I send to Oil Analyzers, they fail to copy the product information correctly and will update my sample after I clarify. I’ll repost with the updated results. I also requested a particle count out of curiosity. Filter is an AC Delco UPF66R.

Let me know what you guys think.

I see oxidation is colored red @ 32. What does that tell us?

If it’s a similar formula to ESP 0w30 virgin oxidation is around 30 indicating ester. I haven’t seen a VOA on ESP 0w20 yet.

Good first report on your Duramax. Will be curious to see how future UOA look. Like you said, ESP is a very good product off the shelves. Thanks for sharing.

Esters. This is best 0W20 off the shelf.

When they give me an updated sheet once they know what the oil is it won’t be flagged red. As stated by several others, ester responsible for the oxidation value.

Planning on doing another UOA during the summer with a longer interval.

Thanks all

@fueldelusion how much engine oil is your Duramax consuming?

Esters. This is best 0W20 off the shelf.

It seems to be. This is comparing VW 508 00 spec that the ESP has with Dexos1Gen3 spec. It beats any other 0W20 in every category.

Should have mentioned that in the post. The rate appears to be about a quart every 5,500-6,000 miles. Doesnt really change based on my driving. With my normal OCI I could get away without adding any.

 

[AZjeff]

Might be more applicable VW 508 00 vs Dexos D

Out of warranty, ESP 0/5W30.

That’s probably what I’ll do. I actually emailed GM Dexos: they said if Dexos D is unavailable, an ACEA C3 or C5 can be used in the mean time. Couldn’t get them to specify if it would or would not void my warranty (despite my best efforts).

ESP 0/5w30 meets or exceeds DEXOS D? That would be an interesting alternative to custom made HPL oil.

@edyvw and if LSPI in a 1.5T GDI engine is a concern?

@edyvw and if LSPI in a 1.5T GDI engine is a concern?

they both pass api sp or api sp engine tests....
no concern in a TGDI engine.

Exceeds. It is min HTHS 3.5. MB229.51/2 are gold standards in approval game.

MB229.52 has LSPI test. VW 1.5 doesn’t have LSPI issues

 

[AZjeff]

Daughter has new Jetta and will run ESP X2 in warranty. We just bought a car with the GM 1.5T

 

[Patman]

It’s interesting that even with 2.3% fuel in there that the viscosity was 8.1 cst at 100c, given that M1 says that it starts at 7.9

For Diesel? I'm not very familiar with Euro specs.
