Ron is certainly correct as it pertains to the V10 driveline. In mine there is all kinds of unfavorable cruise control actions pertaining to fuel economy. One example would be attempting to maintain speed on a steep hill, the throttle is opened and the transmission downshifts to 4000 RPM. Driving without cruise control you can let the speed gradually scrub off, avoid the downshift, and keep RPM down. Another behavior on my cruise control is the downshift on downgrades in an attempt to keep speed from running away. Of course the driver knows best and letting 5-10 mph speed buildup on a downgrade may be be completely OK and it would improve fuel economy.
Keeping the speed somewhere in the 55-60 MPH range is probably the best overall tip. Coasting to stops is another one.
