I am not accountable to you; but there were further details I did not mention...
The car she was drove for 6 hours to see me was "new to us" and had whatever cheap XXXX oil the dealer put in it to call it "fresh." I own too many cars to mess with "short" OCI's; and they are BITOG maintained,
all fluids. I use Amsoil SS 5W30, Amsoil SS ATF, Amsoil PS fluid, Prestone Dexcool, and Bosch ESi6 brake fluid. I have an Excel spreadsheet and I can tell you everything done to those cars since 2005. I usually run OCI (Amsoil) more than a year and I have gone almost to 40K with bypass filtration and UOA. You can change your oil every weekend if you like. You do you and I'll be me.
