2018 Toyota Sequoia Castrol Edge 0W-30

[edyvw]

Here is the UOA of Castrol Edge 0W30 in Sequoia. I am a bit disappointed with this new version. Zinc and Phosphorus are down compared to the previous version. Overall, it is good report, but IMO, nothing exceptional about this Castrol now. We'll see how it does in BMW, which has a much harder life than the Sequoia.

 

[The Critic]

Lower levels of metallic additives will provide some theoretical benefit to catalyst longevity.

These numbers may also just be wrong, this is Blackstone after all. I'd recommend switching to Polaris/OAI.

I wouldn't give BS Labs another dime. TAN is creeping up but from what I have read, the TAN/TBN cross over is not entirely indicative of the oil being shot. This is where the corrosion inhibitors take over. At some point they would deplete and if the oil is acidic enough you'd see a big spike in corrosive wear.

I can't tell what this oil is; assuming its ACEA A3/B4 + certs - not and ILSAC given the high-ish KV100
Must be a reform to meet API SN+/SP also?

Sind die Deutschen nicht gerne Mobil eins 0W-30 ESP?

Only, possibly, if it’s burning oil

This looks to be C3

Phosphorus looks really down for such oil.
I will run a sample in BMW over the winter and send it elsewhere to check.

Not true. All oils will experience some quantity of oil evaporation. All things being equal, higher levels of metallic adds will have an adverse effect on catalyst life.

Eh, I think any effect would be negligible with a healthy engine.

Agree to disagree -- if the effect was negligible, OEM's would have no issues using high SAPS oils across the board. OEM's have to warranty catalysts for as long as 150K in some states and clearly, this continues to be a concern.

I read Castrol states its API-SL - unlike some lighter grades are now API-SQ. Bkstn #'s are suspect.
Though we did also see reported lower Phos in reformed M1 0w-40 FS.

I pulled the PDS link

Based on API SL spec. It should have higher phosphorus.

Thanks for this @edyvw.

I use Castrol Edge Euro 0W-30 in our entire fleet, including our Honda Element.

Here is the latest MSDS, dated April 25 2025. It still looks pretty much the same as previous versions. I'm glad to see it's still PAO.

Sure, but that's often with API-mandated oil quality standards which allows up to 15% Noack for example and their own guidelines for allowable oil consumption, which is something like 1 quart per 1,000 miles (depending on the OEM).

We didn't Euro marques, who spec'd heavier oils, go after reduced phosphorous until GPF's and DPF's were introduced and even then, oils are typically blended with near-limit levels of phosphorous.

 

[EllieMae94]

I’m surprised to see Titanium in this version as I thought Valvoline stopped using it. Or is this coming from residual oil you had in previously?

 

[chris719]

It looks like a slightly higher visc TPT 0W-30 LL01FE now.
