Actually, I drove a Lincoln LS for 5 years that required premium fuel and never used anything but.

It wasnt until I read many posts on X5World that said there was no discernable change in performance with the switch to mid-grade that I ever even considered it using a lesser grade fuel. Still havent done it, was just a consideration.

I am now crucified.
