Sharing some shearing test results about Mobil 1 ESP 0W-30...

[MultiLuxem]

As many have stated in other threads, the new Mobil 1 ESP 5W30 is likely to have a different formulation compared to ESP 0W30 (Lower oxidation number, different additives, etc.).
In the meantime, the Mobil 1 ESP 0W30, 0W20, and 0W40 have similar formulations (based on VOAs online).
What's interesting is that Mobil 1 has different marketing strategies across the world. In mainland China for example, the Mobil 1 ESP series is marketed as the "top-tier" oil (sold at a higher price), and the Mobil 1 ESP there only contains viscosity grades of 0W20, 0W30, and 0W40. The Mobil 1 ESP 5W30 equivalent in China is called "Mobil 1 Classic Euro 5W30", and it's marketed as a slightly lower-tier product. The Mobil 1 ESP series is claimed for 25,000KM OCI while the Mobil 1 Classic Euro 5W30 (Mobil 1 ESP 5W30 equivalent) is claimed for 20,000KM OCI.

In addition to this, in one of the Chinese oil forums (BITOG equivalent over there), there are some oil tests (including shearing tests) for both US Market Mobil 1 ESP 0W30 and Chinese Market Mobil 1 ESP 0W30. Both showed very good results with excellent shearing stability.
Here's the original post: (link removed - MOD)
Both the US and Chinese market Mobil 1 ESP 0W30 have an HTHS of 3.53. Mobil 1 ESP 0W30 (US) has a shearing loss (SH/T 0505, similar to ASTM D2603) of 4.77% and volatility loss (ASTM D5800) of 8.12%.
They have not done tests on Mobil 1 ESP 5W30 (US) or Mobil 1 Classic Euro 5W30 (China), but for reference, they did perform similar tests on the US market Mobil 1 Extended Performance 5w30. Here's the link: (link removed - MOD)
The Mobil 1 Extended Performance 5w30 showed a shearing loss of 7.61% and a volatility loss of 7.97%.

Motor Oil Geek has posted a video earlier of various Mobil 1 oil. In that video, the ESP 0W40 has shown incredible shearing stability compared to other Mobil oils. Considering ESP 0W30 and 0W40 have similar formulations (based on VOA), despite I could not find shearing test results on Mobil 1 ESP 5W30, the Mobil 1 ESP 0W30 is probably one of the most shear-stable Mobil street oils in 30-grade. What are your thoughts?

I think what you said is correct. The Mobil 1 ESP 0w line is the top tier. I'm inclined to think now that the 5w30 may be a tier lower since the reformulation, but I don't know if that is true. The Mobil 1 ESP 0w30 is definitely the most shear stable Mobil street oils in a 30 grade. Mobil 1 Extended Performance 5w30 (US) drops out of grade very easily. It's the type of VM they use. On the Russian oil site, they also found the Mobil 1 ESP line to be very shear stable. Min vis loss.

I agree. Mobil 1 ESP is the top Mobil 1 performance line.

Good detective work ! This sheds light on the popular question of: “Forget the cold temp rating - is Mobil 1 ESP 0W30 an over all better quality oil than Mobil 1 ESP 5W30” ? Conversely , do we know if the two 5W30 oils discussed above are actually the same formulations (i.e. Mobil 1 ESP?)

I think what you said is correct. The Mobil 1 ESP 0w line is the top tier. I'm inclined to think now that the 5w30 may be a tier lower since the reformulation, but I don't know if that is true. The Mobil 1 ESP 0w30 is definitely the most shear stable Mobil street oils in a 30 grade. Mobil 1 Extended Performance 5w30 (US) drops out of grade very easily. It's the type of VM they use.

Based on your post - even with shearing, would you still run Mobil 1 ESP 5w30 for a 5K mile / 6 month OCI in a Kia 3.3L V6 GDI engine with a 7 qrt. oil sump ? *In hindsight , I should have grabbed the 0W30 ESP off the shelf as both ESP oils were side by side at Walmart for the same price ($27) .

Definitely.

X3 looks nearly identical to X4 on FTIR. Seems like it was drop-in replacement for updated SP approval and C40 GT split? Who knows until someone does real testing.

No problem going 5K on that oil. Although we don't know how ESP 5W30 exactly performs when compared to 0W30, its VOA and specs look pretty good. It also carries a bunch of German car certifications.

Not much testing information I could find regarding ESP 5W30, but the Chinese market "Classic Euro 5W30" and US market "ESP 5W30" show the same properties/Specs on the Mobil website.

Take a look at the Chinese PDS for Mobil 1 ESP 5w30 they give you the following:

While the Mobil 1 ESP oil is good, notice how it doesn't necessarily exceed some tests as much as some of the Extended Performance oils, which was my point that in some areas, it's not as good as the boosted Extended Performance SP counterparts. Still very good and when combined with the Euro specs even better (higher HT/HS than Extended Performance 5w30). 20% better sludge than Seq VH and 30% better on IVB. Decent but not exceptional.

So ESP does 30% better on API Seq IVB. Not bad. Also, notice they look for oxidation and max Fe of 400ppm.

Test Parts Evaluation • The volume loss due to wear on each of the 16 bucket lifters is measured using a 3D macroscope. The mass loss of each lifter is also recorded. • Average intake lifter wear volume and end of-test oil iron concentration are the primary evaluated parameters.

The new Mobil 1 ESP 5w30 and Mobil 1 Full Synthetic 0w40 formulas seem to be a mystery. Honestly I’m not sure where they fall now. As a creature of habit I’ve stuck to the Mobil 1 ESP 0W lineup.

With the HPL sale coming up I may make some changes on my new Jeep(Also considering AMSOIL Signature Series). The rest of my fleet will stay on Mobil 1 ESP 0w30.

Purely a guess but I think they may have cut costs a tad and made the Mobil 1 ESP 0w line more premium. But who knows that's just a guess. Mobil 1 Full Synthetic 0w40 now has a Noack of 10%. So it went up a tad.

That’s what I’m thinking as well. With the official SP approval they’re looking to move some product in the US with an attractive price point.

I think I will switch my Corvette from Mobil 1 ESP 5w30 to Mobil 1 ESP 0w30 once I finish up with the last of the old formula 5w30 that I have

I remember times when Mobil 1 ESP 5W30 was absolute gold of an oil. The version prior to the last one, up until maybe 2018.
It had Noack 5.6% and Sulfated Ash at 0.6%.
But, race to the bottom….

Yep! I’m running that exact older version in my Corvette right now but it’s the very end of my supply of it

I had some stash of it when I had BMW X5 35d. But I used it in Tiguan long time ago.

****, here we are with the new bitog darling, 0w30 Esp.

 

[chris719]

This is why I use Mobil 1 ESP X3/X4 in non BMWs. I feel like it’s their flagship product now. Would really like if this oil and the 0w30 got some sort of BMW approval. BMW - harmonize your stupid oxidation requirements.

And it primarily is to allow long drain capability. If you’re not running (very) long OCI that doesn’t really matter.

If I still had my BMW that is the oil I’d use. VW 504 00 is good e enough for me.
