I'm happy with my mostly city, lifetime, truck-calculated 14.8. I've seen as high as almost 21 on the highway.
My 04 titan never touched any close to 20. Around town I was getting 12ish and highway 16ish.
More than pleased with my mileage in this V8 1/2-ton.

I average 18 exactly with mine.

Much better than my 2004 4.0L Ranger (15 MPG)

Jeff's 157 4x4 3.55 has averaged about 19.5 mpg US lifetime on E10 87 (20.3 on the Lie-o-meter) but that's with temps that are seldom below 20F and often hit the 60's in the winter. It would likely be over 20 mpg if he could keep his wife from driving it.

Always would like more.... but, got 33"x 11" tires on 18x9 wheels, 3.31 gears ( would rather have 3.73) but mix of city and highway below. Log most every tank since I have had it.

I own an ac company and drive in the city. All day start and stop. Traffic in Austin too is a bitch My truck is loaded down with at least 1500 extra pounds of tools and parts and I'm pretty hard on it and still average 14.5. It went up about 3/10s after the magnaflow. Lifetime average is 14.9. Unloaded on the highway I can get about 18-19 doing 75-80 mph.

Gas tracker + app for Fuelly.

You have to enter the info on a fillup and it does the rest then syncs data with fuelly online.

14mpg here. But my foot is heavy.

18-18.5 lifetime, 26K miles. Stock Hankooks for now and 3.55 rear. My Lie-O-Meter inflated huge today up to 24 MPGs after I installed my new SCT X4 canned tune. Waiting on my custom MPT tunes and will post an update.
