14.0 gas mileage in an 07 v8 sr5

Lie o meter sticks either there or 13.9.

It's been the same before and after a 3" 5100 lift, 1.5" body lift, stock engine air filter replaced and hdc filter removed. No change.

Shouldn't I be a little closer to 16 or 17 at least?

Fluids look good. Not sure what to check.

My 07 v6 was getting like 21-22 mpg and I was expecting a drop but not all the way to 14.

Ignore the lie-o-meter and check it manually first off. 14 strikes me as good with the mods & the V8.
 
You should be happy with 14mpg. I typically get 11-12 in the city with the a/c running

thats what i average with my v8 on 35s, and all my other mods. thats pretty normal. now if im just cruising on the highway for an entire tank i can get between 18-20. im interested to see how mine changes once my gears are done.
 
Seems about right. I get 13-14 daily driving. I got 14.7 on a road trip through moderately hilly but minimal stopping terrain with AC on last week.
 
Filled up half a tank today. Lowest mileage I ever got, it was 12.8 hand calculated. Everything stock. But I did race a highlander onto the freeway yesterday... he almost kept up

city driving for the whole half tank, also a half hour of idle

My lie-o-meter always stays around 13.x on my completely stock '03 V8. I was expecting slightly more but it is what it is. That is with 98% city driving. The one time I did a tank or two with a lot more highway driving it jumped up to 15.x for a while. That is without resetting it between tanks. I was hoping for more but it is a relatively heavy truck with a V8. Much better thar the sub 8mpg from my old '78 big block Bronco!
 
I just 310 miles after filling up. 17.2 mpg, cruising between 70-80 through the hills of PA in the rain with semi traffic. That was calculated manually. And I also put 89 in this trip.

Just like above, I'd do a manual calculation. I've done a Seafoam bottle in the fuel tank in the winter and will be doing it again this week prior to another long road trip.

2006 4x4 V8 with 265/70's. New plugs, oil, carbon air filter removed, pcv valve, air filter with 148k on the engine and I get about 13/16 city/highway.
next up is to cycle the trans fluid but let me know if you find and answer.
 
No mods here except a rola rack on roof, and I consistently get 16/20 per trip computer but I do drive conservatively.
 
If you don't have stock tire size then the lie o meter is null and void. I run 285's which throws off my speed by 9%. If the speed is off then the distance traveled is off.
Mine will usually stay between 14.7 and 15.5. My SGll will always show 1.5 to 2.0 mpg higher than the vehicle. The SG is dead accurate which always amazes me.
 
HA. I get 13 on my v6 with just 275 ko2s and a 3 inch cornfed
