Absolutely Senior; On the way from SoCal to Denver (uphill most the way) I averaged 7.8 MPG at an average cruise control set speed of 58-60 mph. On previous trips with flat terrain, I have achieved a high of 11.3 MPG. Not too pretty but you didn't buy it for the gas mileage :) Be aware that on steep hill climbs, your cruise control will completely cut off if it can't maintain the speed that you set it at. Scared the beetle juice out of me the first time it happened! Lesson learned . . . cruise control has it's limits! According to various web sites, the V-10 gets it's best mileage at about 2300 RPM. Let that be your guide and of course, your experience (and others) will vary. HAVE FUN!
