That is one factor I consider when buying fuel, freshness.
In my area all fuels have 10% ethanol, so we have no choice to not use it.
I've used fuel from many different stations and none have yielded any negative running conditions.
But freshness is something I look for as ethanol is hygroscopic, and it's been said that if the fuel becomes water contaminated, then octane can fall by 2-3 points. Using 93 allows for water contamination octane drop to still adequate levels. Using 89 could drop octane to 86, not good for turbo engines running at high demand.
However, another factor is how well sealed the stations tanks are.
If they're properly sealed, then there isn't much chance of water contamination, or so it would seem. Interesting.
I still prefer stations that have high demand and turn around as there is less chance of water contamination due to the ethanol.
That seems more important than which brand is used.
