From what I've seen in youtube videos, it's possible to run E85 in a SN95 vehicle. From my understanding, the fuel pump and injectors would have to be upgraded and a return fuel system is necessary. Plus a tune would be necessary. I'm thinking more along the lines of doing E15 instead so I'm wondering if anyone has tried to do so. If others have successfully got their SN95 Mustangs to run on E85 then E15 should be possible without having to do a bunch of upgrades. I suppose the E85 upgrades...
