14/19!!! OMFG...what are they smoking? Honestly, I average a solid 10-11 mpg. I've contacted both my selling dealer's service Dept., and a closer, more local one...and they both said 10-12 mpg is about what one can expect with a 4.8i. If you are getting 14/19....you are damn lucky!!! Also, for those who "think" they're getting great mileage in a 4.8i (more than the 14/19, you cannot rely on what the OBC says, those are really, really happy numbers!!
