All that acid in RLI oil (Renewable Lubricants)

[benjamming]

So, API, ACEA, engine mfg, etc. testing protocols aren't always all that?

Thank you again, RI_RS4. You truly are an asset to BITOG.

I'm reviving this thread from June to show that the highest TAN shown above for used Bio-Syn 5w-*40* oil is 5.3 . And in that case, the used TBN was 3.

The TAN for my used BioSyn 0w-30 oil was an astonishingly high 8.5 (and TBN of a meager 2.0). I only went 7,510 miles on my oil, but over a long 9.75 months.

I don't know how many months the 40-weight Bio-Syn above was in use, but the table shows it being used for over 10,000 miles.

So I have to wonder about either (1.) quality control or (2.) excessive time lapse (9.75 months) on the 0w-30 weight oil, especially if the virgin TAN started between 2 or 3, as so many 40-weight BioSyn virgin samples have. I also hope no damage was done to my engine and/or seals.

I know this is an old thread but this may have interest for some. I'm about to get an oil analysis done on some RLI that's been in my Honda Fit for over 25,000 miles -- an accidental, extra-long OCI. I've been averaging OCI's between 15 and 20k in my '07 Fit and '01 Odyssey with good UOA's from Blackstone. I'll post my UOA's in a new thread after I get them back from Blackstone. I might pay extra to have the TAN done, just to see what all the fuss is about.
