[QUOTE="ElscottHavoc, post: 14089454, member: 93145"] Here's something I wonder. Here in Iowa, Super Unleaded has always been subsidized due to ethanol blending. The additional ethanol bumped up the octane to 89, but the subsidization made it 10 cents cheaper than 87. So 89 was cheapest, 87 was middle and 91 was highest for most stations. Some stations, such as Wal-Mart must have done further ethanol blending because they offered 89, 91, 93 with 91 being cheapest and they also typically beat competitors by 10 cents. Essentially, unless you specifically needed regular unleaded non ethanol blend, 89 was the way to go for most cars. Recently, Iowa (and perhaps Nebraska) started requiring all unleaded gasoline to be ethanol blended. Now, when you pull up to the pumps, most stations have both super unleaded and regular unleaded at 87 octane, but super unleaded remains 10 cents cheaper. My assumption is to be the same exact octane rating, they must share the same ethanol blend...otherwise, if one had more ethanol it'd be slightly higher octane - correct? Yet, there still remains a price difference between the two...so what's the difference now that would cause two equal octane ratings to necessitate separate pumps and prices?
