How does it work Bill? Any idea if it's a friction or viscosity modifier? I remember when I started using Mobile 1 in my old Mercury Marquis, that I got about a 2 mpg increase, but it had a much lower viscosity rating than the "standard oil" I'd been using. Now, of course, Ford's oil for gas engines is 5W20 as I recall, so there's not much you can do to improve on that.
And, any idea if Rev-X for gas engines is supposed to be as good as what you found for the diesel?
