[QUOTE="Black AOD, post: 1545201, member: 16536"] I Averaged about 14.5-15mpg between city and highway. I'm averaging between 18.5-19mpg now, same driving scenario. A lot of my driving is highway rolling 70-80mph. My to and from work trip every day is 55 miles round trip and that's at minimum. Of those 55 miles (daily average, 85-90% of it is highway) It's not uncommon for me to drive 500+ miles some weeks I'm not convinced quite yet that this is right. I'm going to go through a few more fill ups first to see if it continues.... If it is, this is going to be an unexpected nice surprise since my truck has the factory big fuel tank capacity (48 gallon) [/QUOTE]
