That said, it's not really a big factor for me as price and convenience tend to rule the day so I end up filling up at BJ's or Sheetz quite a bit. I drive all my cars for well over a decade and have never noticed any issues with deposits.

Consumer Reports picked up on the AAA analysis of Top Tier.

I'm sure there is a difference in a lab. Whether it's meaningful in a given situation, whether Costco is scrupulously adherent to the program (or sells non-Top Tier gas in a pinch), and whether the mutual distribution system of pipelines, tanks, and delivery tankers always preserves the distinctiveness of Top Tier are reasonable questions. I buy gas at Costco mainly because of the price.
