Steve:
I used it once when the noise of my fuel pump became pronouncedly louder. The thought was, it would help lubricate the bits that might be wearing out. I don't know. I didn't notice any improvement either in the noise level or the MPGs. It did puff out a few plumbs of bluish smoke, though, as kind of rebellion. Still, my fuel pump continues in strength.
Cheers!
Scott

Well something is wrong with my car as it has very finicky power issues to boot. Put that stuff in there and my car wont go over 50 MPH. However used in an S Type and my car (before it 'broke') and saw no difference.
