2022 Corolla Cross HPL PP 0W-8 30k mi OCI

I am curious though - why?
Do you doubt my data ?
It is enough of a challenge to create an image and post it already.
All info is provided to WearCheck in the first place.
Should I do additional UOAs, I will be sure to mention this.
Gotta go.
Rush deliveries to Monterey and Tracy.
Let's talk oxidative thickening !

No, not the “data” you’re posting.

No one's doubting you - but minimizing modifications to the report adds credibility.
It takes under a min to use the Windows snipping tool, followed by Paint to cut out personal info. I'd be happy to help...

Understood. Thank you friend. No one critiqued my penmanship in any previously posted UOAs.

I can think of other crucial, more compelling things to talk about.

-Oxidative thickening.
-Fuel dilution.
-SAPS vs boosted add packs.
-Competition for surface bonding.

This is a horrific UAO.
But it is real.
Embrace the efficiency.
 
But you do.
Others ponder over the invention of the wheel.
My next frontier is the mythic, mystical world of "sludge precursors."
Back to work.
I'm only drivin'.
No, not at all. I don't think you falsified the spectrographic results.

However your post above does illustrate the problem I do have and that's with your ability to adequately interpret and understand the UOA, more along the lines of competency and cognitive ability. The reason I say this is because every time anyone asks you technical questions about your posts (or questions the applicability altogether) you revert to this type of response.

I'm only reading and asking.

Once again, for the record, I stipulate that there is no technical background here.
 
Nitration creates sludge precursors that can cause sludge formation, but only in the presence of other contaminants such as water, fuel, or soot, and mainly as the engine is warming up. In this particular case, with an engine that is almost never cold and with those other contaminants in check, I wouldn't be worried too much about sludge. Oxidation products are mainly what contribute to varnish.
These are my thoughts Sir.
 
Folks I'll be direct, any member I have to moderate, again, in this topic will receive time away.

I re-opened this topic, as a courtesy, so folks could discuss.

Stay on topic and skip the petty bickering.
 
What does HPL show for the KV100 and HTHS specs for this 0W-8 oil?

As already meantioned, the UOA KV100 was half way into the 20 grade range, so that helped give some added MOFT. If the oil actually stayed in the 8 grade range for the whole 30K miles, the results could be somewhat different. Keep in mind this engine is speced for 0W-16, so it has design features to handle thin oil from the get-go.

Great report. Try 40,000 next oci? lol

[edit] Ok finished reading the thread since my prior response. What's equally as remarkable as the report is how much you drive. I personally could not do it, my (backside) does not have range in it for the short amount of time this oil was run. My parents are orginally from the Bay Area and I've spent lots of time there. I really don't like driving in traffic and for that reason the last 3 years have been a win for me in that regard. I work 90-95% from home. If I had to take runs to Monterey and Tracy in the same day, I would need a Xanax when I got home.

I feel ya on all this, Brons2. It's a little different, delivery driving vs a long commute.

Audio books, podcasts. Shame there is no SXM BITOG Radio station.

I have actually had a repetitive motion injury on my right foot from stepping on the gas/brake pedal so much. The pain was only managed by using a special curcumin supplement, a great NSAID.

I have always liked the idea of Texas, and what it is all about.

Thank you for the feedback, Zee06.

My sense is that all is well, even with the jump in viscosity from 20k miles to 30k miles.

ILSAC GF-7 will arrive a little after pictures of my oil filter and under of valve cover are produced and posted.

HPL PP 0W8
cSt @ 100° C 5.62
HTHS 1.929
Reported virgin numbers.
 
I would love to see HPL ANY oil do those miles in a small TGDI vehicle.

FTFY. No oil is going to last long intervals in a heavy diluter. The benefits of lower volatility (reduced piston and valve deposits), better shear stability (still in grade despite the dilution), and higher TBN/alkalinity (organic acid growth prevention) are still there.
 
Direct…. I’m retired 😁 so I don’t put many miles on. But right now I do more local short trips with 2 weekly highway runs. I’m chicken about going over OLM.
