I was thinking about buying a 1500 HD 6.0 and was wondering what MPG thispickup isgetting?

If not I will probably buy a2005+ 1500 5.3 and was wondering whatMPHthis truck isgetting?

And ifanybodyresponds do you have an aftermarket exhaust,air intake/filter, ect.....that helps improve the MPH onthe abovepickups?

Thanks!!!!!!!!!

 

what year 1500 6.0 and 5.3 for that matter, and is your driving mostly city, highway, or hauling.

I've got a NBS 07 1500 with the 5.3, i get 15.5-16.5 city/highway mixed (mainly city) This weekend I'll be (hopefully) be taking advantage of an empty highway and reporting mileage of close to or over 20. But with the NBS models you have the AFMS which will save highway mileage.

Used trucks are going to vary in mileage depending on how they were kept up on maintanence. Search the forum for "mileage" you should get a thread where alot of people posted what they get.

 

By the way, my truck isstock, and I've tried to get my mileage to go below 15mpg (to see how aggressively I could drive without killing mileage) and as of yet (15 months) I've been unable to get below 15.4 mpg on a tank.

 

2000 silverado 5.3 vortec
17.5 mixed
22 freeway
k&n airfilter/HALO plugs
mpg improves after 70K miles, it losens up.

 

I've got a 2008 GMC crew cab with the 5.3, that gives me about 13-15 miles to the gallon in the city and about 18 on the highway. When i pull my trailer i get really crappy gas mileage. I get better gas millage out of my 1994 silverado with the 5.7 that is bagged on 22's, but that is only a weekend crusier!

 

ive got a 2006 5.3 z71 14.5 mpg city

 

2001 2500hd 4x4 6.0 4.10 gear's . average 11.5-12.5 best 13 in 2wd summer winter with the plow 8.5-9

 

My 2007 6.0L gets about 13.5 city & 18 hwy with 3:73 gears & GM cold air. Pulling either trailer it's about 8! It sure is a hoot to put it in netural down hill & try to hit 99mph

 

my son has the 6.0 liter in a 2007, 2500 series with 4.10 ratio. He gets about 11 mpg, but company pays so no big deal to him.

I have a 2000 obs,2500 series, 350 engine with 3.73 ratio 81K miles and drive itvery conservatively.

Truck runs/starts great, but got 12 mpg today, wonder if a tuneup would help, however, a complete AC Delco parts only tuneup is about $250.

Might be better to save my $250 to buy $4-5 gas.
any experience on this,would a tuneup help at 81K miles?

have a good day,

 

plug's and wire's would not be a bad idea ,i had a 98 k2500 w 350 and 3:73 gear's it's just the nature of the beast ,posted right on the sticker (milage epa estimate's do not apply ) 10-12 is not out of the question ! it's a work truck.
