2007 Silverado 6.0L Vortec Max

Hey out there,

Can anybody that is driving one of these share their average fuel mileage? I am getting like 15-16 on average. I have the active fuel management.
Thanks

I think book calls for 20+mpg on highway and 16 city....

I know real world most people are getting about what you get..

sounds right. The government website says a combined 15 so your right on target.

A friend of mine bought an 07 silverado with the 5.3 engine and with active fuel managment and he gets terrible mileage. For a while he was getting 12-13mpg with a 2wd brand new truck (after break in period). My 97 Z71 gets a solid 14-15 and it has 192,000 miles on it and a 5.7 liter!!! Whats the deal with that?

I have the 5.3L and got 403 miles out of a tank this past weekend. Granted it was all highway driving but it was about 17-18 mpg. 20 mpg is what they rate it at but that is not a reality.

i have a 4" lift on mine with 20's and 33" mickey thompson mud tires i get about 11.4.. and thats gone up i have the edge evolution chip on it which has brought it up about a mile and a half per gallon along with exhaust. need a cold air which will help a bit too!

I had a 6.0L with 4:10 gears and it got 13mpg at best.... 8-9 when towing.

While that's not great, you guys need to remember that trucks are built to work. If you want fuel mileage buy something else. The 1/2 ton trucks are gonna get the best mileage over the 3/4 ton's and up. V6 trucks don't get any better mileage either. I just bought an 08 Sierra 5.3L 1/2 ton with 3:73's and it gets about 15-16, but only has about 2,500 miles on it. Hopefully it'll get better after 3,000, but if it doesn't, at least I know it'll still tow my boat to the lake.

my 08 with 5.3 gets about 15-16 in town, and 18-19 on the freeway.

I have a 2003 Suburban with the 5.3, and I consistantly get 18-19 on the freeway at about 70-75...and it doesnt have the the fuel management technololgy
