Check PQIA for a VOA on the conventional,
I worked at a Racetrac for a few years after high school/pre-military years, they didn't have synthetic from 2010-2012 when I worked there.
I ran the conventional a few times in my old 2.3L 2005 Ranger for 5K mi oci and it never had an issue, if I remember correctly, they're a Warren product, or were.
