I used to get a good 15 to 17 even in the city, but now with the ATZ's, only 13 lol. Doesn't sound like much but i can tell a big difference
I've only had my 04 FX4 for a month or so but averaging 17 overall which is what I expected. Came from an 01 Expy that did about 16. Sent from my DROID BIONIC using Tapatalk
