It's a 2002 Ford Taurus SEL. DURATEC 24V.
The sticker on the flap for the fuel cap access panel says to use ETHENOL or Regular Unleaded only. But the Vin number of the car doesn't start with the right letter for it to be a flex fuel. So what gives? Was the sticker placed there in error? Is the DURATEC set up for burning alcohol from farms instead of petroleum? Or will this damage the engine? The Flex Fuel is a modified 3.0 Vulcan from what I remember.
