Super unleaded was midgrade until late last summer when ethanol was mandated in regular grade. At that time many chains stopped carrying 89 octane and started to carry two formulas of 87 octane. GasBuddy defines midgrade as 89 octane, so we are playing by GB rules. Yes, for years "super unleaded" meant 89 octane in Nebraska and a few surrounding states, but we were the exception from the rest of the country. The "super" label is a holdover that does not mean the same as it did a year ago. Now it still means ethanol, but the octane rating is only 87. Some vehicles need 89 octane, why send them to a station that doesn't have it? That erodes the integrity of the site. There is a topic open in the Lincoln forum. Would like to have a discussion there.
