Typical V8 driver response! In fairness, a friend of mine with an S reg BMW E38 728i gets about 25mpg from his straight six on similar roads as I drive whereas I average about 23mpg in my 4.2 V8. In for a penny, in for a pound...might as well live a little with the V8! I can confirm a 4.2 A8 will blow a 728i into the weeds. Hardly likely to make the news, but still!
