All Eagles are unleaded. All gas is unleaded these days. Those stickers were for back in the day when leaded gas was still available. The filler hole was decreased in size so the leaded nozzles would not fit. Also, you can use Ethanol blends of up to 15%. Most blends are around 10%. I have used ethanol in all my vehicles for many, many years, with no problems. My Ambassador was converted to use unleaded gas with the installation of new valves in the engine. Its a high compression engine (10:1) and runs the 87 octane just fine.
