I've read the whole thread. Blackstone has the capabilities to test wear metal which ultimately matters most. If the RL oil was the godsend oil he says it is, the difference is wear metals should be obvious but I just haven't seen it. Everything Daniel said makes sense, but tangible benefit hasn't been seen. Lance is the closest to a scientific test we've gotten, and likely will get.
This might actually help you. This post shows the drop in iron from both break-in and from switching to RLI. I switched to RLI at the 10k mile point, so the first RLI report is at 20k miles. I missed a test at 15k.

Very impressive wear numbers. I still question whether wear is actually any lower than it would be with another synthetic but great to see such good-wearing results from RLI none-the-less. If I saw your iron drop into single digits I'd be a true believer haha.

Yeah, tell me about it. I was hoping to see the same thing. Going from 14 to 12 is better than nothing, but definitely not a huge drop.
3rd owner, first UOA @ 123,004 miles. Quaker State Ultimate Durability 5W-30, after valley plate repair, sampled mid-drain after warmed up (oil temperature gauge at one hash below midpoint).
Comments welcome.
Has anyone correlated this battery of tests to the "Quotes/Orders" section on the Tribologik web portal?
It is a bit opaque, but as near as I can tell, these correspond to:
Test package: Bearing – Basic
Additional tests:
Base Number (TBN) - (ASTM D4739)
VISCOSITY INDEX - (ASTM D2270)
Water (Hot Plate) - (TRIBOLOGIK)
Fuel Dilution
Glycol Detection - (TRIBOLOGIK)
Have not been able to find “VISCOSITY/100 [ASTM D445]”.
Do we have a feel for fuel dilution threshold or measurement tolerance? Maybe I missed it in Daniel's part of the thread. I always feel weird about making decisions based on small numbers without knowing the tolerance or error bars.
I am 3k miles into current fill of Pennzoil Ultra Platinum with 3x RLI Booster Paks (85901). It will be interesting to compare results.
Blackstone's fuel dilution numbers are not even close to reliable. They do not have the proper equipment nor do they have the certifications to make any fair assessment of fuel dilution. That's why I was saying I should send a sample to Tribologik or an equivalent certified lab to see where RLI is on the magic fuel dilution scale.

I just changed the oil on both cars, so it's going to be a bit before that gets done. I'm starting to get a collection of 5 gallon pails in the garage now. I'm wondering if I should just get a drum instead. At least it would last about 12 oil changes, and I seem to be in the 4 to 6 a year range between the two cars getting daily driven.

I agree completely.
I have perused the "Real or Synthetic Oil..." thread and understand the background.
In post #202 I was referring to the Tribologik test report for the GSF attached to post #130 showing fuel dilution @ 2.3%, which is in-family with my ISF result @ 1.6%.
I need to send a sample off to "whoever is reliable/certified/cost effective" to see how my driving habits stack up. Since moving to Hawaii, I barely get 2-3K miles in a year on the IS-F. Lots of stop and go driving around here so my driving habits/environment are roughly 90/10 (city/hwy). Plus I need to see how I can send my samples off because Hawaii is big on ECO everything. We get charged plastic bottle fees and required to buy some oil absorbent to dispose of used oil (Autozone, Oriellys, etc. does not nor have a used oil drop off like most stores in the mainland).
I'm currently using Cost Kirkland 5W-30 (from what I can tell by the Dexos license number is from Warren Distribution). I didn't see the need to buy boutique oils at the time since I do not drive the car much nowedays and either was doing a 1 year/3K mile oil change (whichever comes first) due to my driving environment and habits here. Any opinions and tips are welcome so post up. I appreciate your years experienced input over the years on this forum lobux.
Here is mine, oil was in the car for 1.5 years ( I know, it slipped my mind to get it done) but I only drove around 2k miles in that time. I think I used Costco Synthetic or it might have been Mobil1, but in any case..it was 5w-30 with OEM filter. Going Costco oil this time around and will post in a year or so from now.
Finally had an oil analysis done on my F, overall I'm happy with it. I wish I was cool enough to be in the single-digit iron club but oh well. This was a one year run with Costco Kirkland Synthetic 5w-30 and OEM oil filter. Looks a bit fuel diluted so I may run a bit shorter from now on but not sure yet, certainly doesn't help that I drive it 5 miles to work each way everyday but I make sure it gets longer drives each week. I do short pulls most days (when not raining, dang PNW) and did one autocross this summer.
For those of you doing extremely short trips and have less than 3K-5K miles in one year or more, I may do the same by just changing the oil out by time instead of distance if there's decent fuel dilution. From what I've gathered over the years is Blackstone Labs doesn't accurately measure fuel dilution so I'm going to use someone else (previously used them for my prior vehicles). I drive maybe 1-3 miles at any given time since work is so close to me and not much places to drive distance wise on Oahu (Hawaii). Every now and then I take it on the highway for about 30 minutes but even then I'm not even sure if I'm doing a good deed on this engine/oil by doing that? Back when I was in Texas I didn't drive as much either but I was still able to manage at least 3K miles within 6-8 months.
