Hi I just picked up a 2012 XLT leftover with 160 miles on it in Gem Green at a great price. I am a little disappointed in the mpg only getting 15.3 in town. I like the truck have always owned Fords and will continue to do so. I have noticed a little lag when I get on it maybe just need to learn to drive it. What grade fuel does everyone run? Owners manual say 87 octaine so thats what I have been running. Just want to intorduce myself.
