I was just wondering what you guys get in miles per gallon and how you increased yours.

I get around 15 but havnt done anything to my truck yet.

 

i get high 15's/low 16's. Maybe 18 on a trip. Could squeeze a couple more mpg on both if I could keep my foot out of it.

 

High 16 to low 17's

What I've done? K&N filter. Flowmaster exhaust into duals. Bored throttlebody.

All I really need to do is learn to keep my foot out of the engine, and I'll be better...

Naaahhhhhh.... :-)

 

+1 for me too. Most of my driving in around town, less than 5 miles with multiple starts a day.

What is the best anyone has gotten with a fill up and pure highway cruising at consistent speed with cruise.

 

I have gotten driving highway with cruise control set a 60mph around 24 mpg. I only got k&n filter and borla exhaust. i'll get around 18-19 mpg on the city if i'm not flooring it all the time. Damn borla exhaust ! lol
But i'll do it because the awesome sound and like to see the people turning heads and asking questions... AWESOME.....

 

4.7l, 14/20.

 

High 21
Low 16

Average 19 (21 mile commute mixed driving)

2008 4.7L

 

when i run e85 i get about 14/17
on reg 87oct around 15/22

 

With the blower on and current mods 16 in town and 22 on the highway.

However, that changes drastically with WOT and when I take the blower off. With current mods and blower out I get around 10 mpg.

 

ALSO got to remember what the variances of 4X4 or just 2wd that will effect the gas average also...i did an experiment with mine last summer.

I have Injen CAI
3923 Autolite spark plugs
69 true Bore TB
flowmaster exhaust exiting out the side
Truck is 4X4

when taking it easy...granny pace acceleration i got 18.2 city and 24.6 HWY at 50MPH.

when always in the throttle i got 14.7 City and 21 HWY
