I have a 2004 chevy 2500HD 6.6 Duramax Diesel, I get 12.5 city and about 15 on the highway with no performance upgrades. Those 6.0 vortec motors always seem to get poor mpg. To increase mpg and even more horsepower you can try buying upgrades that save fuel such as a programmer (chip), exhaust system or air intake system. I recently ordered a turbo-back exhaust system and a banks ram-air intake system I am getting about a 3-4mpg increase. I am soon purchasing the ATS diesel programmer which i am told will give me an additional 2-3 mpg and a huge power increase, (but these are diesel numbers, gas is a whole different world) but it can still help you out at the gas pump. If you are running regular unleaded gas in your truck you can try running a higher octane gasoline such as plus(89 octane) or premium(93 octane) in your truck because higher octane fuel burns cleaner and can give you better fuel milage. Hope this helped! - George

Your numbers are about right. I have a 2006 HD 4x4 its getting between 12 to 14 mpg. I'm running it half and half hwy and town. We feel your pain at the pump.6.0 ltr. Vortec pay for the power.

I had a 2007 2500HD Ext'd Cab Long Bed with the 6.0L (2WD) and I got 9.9 in city and 14.8 on highway. But when I add Octane Booster (fuel additive found at most Auto Parts stores) with every other tank full and the MPG went up to as high as 17MPG. Now I own a 2012 2500HD Crew-Cab shortbed (2WD) with the 6.0L and I am practicing the same method of additive enhancement. Try it and let me know if it worked for you.

Trying too make this my Performance Truck/While getting the job done. Can anyone tell me how to get. Lots of HP Gain and MPG Gain. Please Help.

check your rearend ratio- there will be a code in the glovebox on a silver or white tag with a black strip on top- they are in alphabetical order- GT4 is a 3.73 and GT5 is a 4.10 rearend- if it is a GT5 then that is about right- if it is a GT4 then it should get 16 or so hwy and 12-13 city.

I have a 13 Chevy 2500HD 6.0 Single cab long bed similar to the white truck I have Airaid cold air intake throttle body spacer with throttle body, custom true dual exhaust with headers high flow cats Flowmaster 50 Sieries with echo tips, 2inch level lift kit, running 33's, upgraded ignition coil packs with thicker spark plug wires and upgraded spark plugs with high volume oil pump to get rid of that annoying knock in the morning no programmer. I run mostly highway and average 18mpg while pushin close to 400hp now bhp I don't know about. But I do pull a fifth wheel travel trailer with weighing a little over 10thousand pounds and my 6.0 hates pulling the trailer at 80mph but with the trailer I average about 12mpg with my foot buried to the floor. I should of bought a diesel.....

Canada here. 6.0 2008 on gmc 2500 wt long bed. Ext cab. I get about 4.5 to 6 km/L. Converting to miles it's about 10.125 miles per galon. On the low end. That is city driving. Considering what the engine is. It's probably the best we'll see. Now it's your choice. Dump a lot of money in stupid upgrades to get a mediocre economy increase. Or just drive it and use de money for gas and avoid premature repairs!

Get a Honda if you want gas mileage. Duh
