Helpful to nail down the proper interval. Also BITOG.
Having them done by two different companies adds to veracity of data.

Hi Buster.
The 4989 report was a 5/30 installed by a GM dealer. It was billed as “Dexos 1” it is probably AC Delco or Mobil Special I think.
Report here: Mobil 1 5W/30 ??, 4989 Miles, 2005 Civic 1.7
The 8948 report was 5/30 M1 EP.
Report here: Mobil 1 5W/30 EP, 8948 Miles, 2005 Civic 1.7
Next report on the AP is likely 15,000 miles and it will be over a year old. Question is If I change it then or keep going, which I have not decided.

Discussed extensively on the prior thread.
I’m not really worried about the make up because a good portion of it is due to sampling ALS bottles are actually a little larger than Blackstone. Finding out the exact measures is on my list of things to do.

Based on recent info … both M1 AP & EP in 0w20 had majority PAO and the same amounts … I’m buying EP for $25/jug and run to OLM around 7k … once out of warranty … will look at Tigs program at 10k on EP … no UOA needed …

EP 0w20 was about 70% PAO per MSDS, and AFE was around 30%. Base oil composition percentages are hard to really know. Both AFE/EP 0w20 are excellent oils.
AP is a more robust oil than both EP/AFE, but in what specific only XOM knows. Likely anti oxidants/oxidation resistance. They also clam unsurpassed wear control based in the SEQ IVA for the AP line, not the EP/AFE. That may not mean anything as a comparison though.
There have been so many varying opinons on TBN and TBN/TAN relation that I don't know what to think about TBN.

I know we like our SDS Buster to purportedly crack the XoM mixology nut, but I would not trust it as being representative of current formulations given the new base oil advances and GTL availability.
I will say that if I still had my Honda Fit Sport, Id be trying some Ep to see if it gave me that old PAO slip, clatter and free revving feeling from long, long ago in MObil 1 History.
You don't easily forget your first PAO

Very quiet for me now ... but the entire M1 20 vis evolution belongs to Tig ...

That is curious. We had some discussion in the previous thread about how TAN may not be as representative in newer oil formulations.

Maybe it's due to the makeup oil?
I am not sold on this TAN/TBN crossover point anyways. I never seen this on BITOG before. Can somebody point me to a reputable source advocating using the TAN/TBN crossover instead of TBN?

Perhaps. It is a pretty small amount of make up oil over a fairly long interval though.

We see too few UOAs with TAN to really draw any conclusions in my opinion. If you do some searches on machinerylubrication.com you will get some information, some of it conflicting.

Incidentally here are two sources which seem to disagree on TAN.

Personally I would value the companies doing the UOA's guidelines more. They are doing the UOAs and if they are giving people bad advice there could be issues.
From this chart the TAN is very unpredictable and varies a lot more compared to TBN. I'm guessing that's why it's generally not used to make guidelines.
