How can you be so sure Steve, especially since you do not own a SVT Contour? The SVT supplement to my Contour manual states Premium Fuel Only, with a 91 octane stated as minimum. There is also a sticker on my fuel filler door that states it as well. I am also pretty certain under the fuel gauge it also states the same.
exactly what i was going to post.......and yes it also says premium fuel only in the gauge cluster
