I saw someone selling some old supertech full synthetic on Facebook marketplace. I don’t remember the bottles ever looking like this but I’m a younger guy who probably wouldn’t have given it the time of day until recent years.
I'm guessing it's an old bottle that was sourced from Citgo, I think all Supertech is now made by Highline Warren, and they don't have different regional suppliers and I don't think XOM nor SOPUS makes any private label products anymore..
