Thanks!

buy the lowest cost , high volume fuel for the freshest fuel.
ie the station with all the cars in.

Indiana had some bad fuel last summer and fall.

Short story is this. They did a test of fuel/gas stations all over, from Wisconsin, Illinois, Iowa, Indiana, Michigan, etc; and found the gas was 'often' not what it was advertised to be. The octane was often 2 or 3 points lower, than stated on the pump.
So, they recalled all the sleds with hi- performance engines, and re decked the heads to lower the compression. Then, they sent out notices to 'try' to avoid 'mom and pop' small town gas stations. In those, the fuel sat in the underground tanks too long (often), and the gas octane deteriorated over time. Also, condensation added moisture to the gas.
The problem was way less evident at main brand type gas stations, particularly busy ones which re-filled their underground tanks, more often. There was no measurable difference found, between brands! All, were sometimes lower octane than the pump said, by a point or two. 93 octane was often 91; 89 was often 87; and 87 was often 85 octane.
That is why we often burned Aviation fuel, 100 octane, in our high compression race engines. Federal regulations, for aviation safety, demanded that the octane was in fact, 100 octane. We were running 15.3/1 compression engines on 100 octane. That same engine would burn down in 1000 feet, on '89' octane fuel (which usually wasn't really 89). Ask me how I know that?

So, probably IMHO, any quality known brand station is alright. Especially if it is heavily used, demanding it to re fill it's underground tanks often with 'fresh' gas. That, is important!!!
