Chevron's Vartech was added at a 5% concentration and was in use for the entire OCI (not vetted for automotive use).

Found it interesting how the fuel dilution has greatly improved since switching to 91 octane.
More previous UOAs of this engine, it's obvious which had 87 octane in use:

I've been doing short oil changes due to fuel dilution from short trips. In the last 6 months, I've been using 91 octane as the car seems more responsive. Looking at the analysis, there might be more benefits to using 91 octane. Only 4 of the fill ups were 10% ethanol, the rest were ethanol...
