What is your average MPG (City) / (HIGHWAY)

[Okura_hubby]

Lots of rants on what is going on. So I thought lets collect info..

Basically what I would like to collect is modifications (Suspension/Tires) (yes or no) and modifications to exhaust/intake (yes or no)

And what is your City MPG and what is your Highway MPG.

Then we can see what is works best.

2.5" lift, 31" tires, K&N 63 Intake, Hypertech tune

17 City, 24 Hwy approx.

I averaged 4 tanks on several trips to college station. Texas is pretty flat though, where i live. I can normally travel from Beaumont to College Station/Bryan on a little over 1/4 tank. With a loaded trailer it was half a tank. Thats about 170 miles one way

My auto computer on my dash says 19.7 average for my last tank when I was doing mostly highway driving. Since I've been driving around town it's been 19.2. It has an aero turbine muffler, other than this, no modifications (at least until today when I found out I'm getting a new transmission -.-)

City 16MPG / Mixed 17MPG / Highway ?? (Haven't done pure highway yet...).

Stock, no lift. Although it's running a bit rough when cold, need to do spark plugs and check for vacuum leaks, no idea when previous owner did them last, haven't really checked them either.

My absolute best so far is 21 (100% highway. And mostly downhill Averaging about 125kph)
City average is about 14.2 (usually about 90% city)

Stock. Low mileage. I don't understand how guys can be getting mid 20s. I don't have a heavy foot...
