My Toyota service department says they’ve noticed that over time gasoline from Costco tends to cause more wear on engines because it doesn’t have additives like techron or techroline found in some brands of gasoline like Chevron, Texaco or Mobil. Does this make sense?

Costco gas is fine. Was the guy telling you this wearing his tin foil hat? I wonder what other tripe he’s been feeding customers.
