mine got 15 city/17-18 highway when it was 100% stock.

 

its funny they have all this fuel saving technology on these shitboxes but they still get horrible mpg

I prefer driving a pickup and a truck has been my primary transportation since 1971. The new pickups get exceptionally good mileage over their predecessors which makes them a viable vehicle for everyday pleasure use. I thought I would have to give up driving a truck during retirement because of the cost of operating, but no need!

I don't know about that, my 2004 Silverado I traded in for my 2014 got a consistent 20mpg. and it had 212k when I traded it in. same cab config and both 4wd trucks. both 100% stock.

 

doesn't matter much now, with my new 35" tires ill be lucky to get double digit mpg

Not exactly surprising considering most of the information posted on this forum is how to remove said technology in pursuit of power, aesthetics, off road capability, etc

I do know that all vehicles are tested on 100% pure gasoline and not an ethanol mix when the mpg ratings are developed for the vehicles during manufacture. So the sticker on the window will almost never be what you get.

 

Not to mention the EPA tests are done on a controlled course at something like 55mph. So the number on the the window sticker labeled "highway" is inherently false from the beginning.

 

If they want to tell us a true "highway" mileage, the test should be done at 70 mph min.

I'm wondering why I'm get really poor mpg. All I have is a lvl kit with all terrains and a k&n air flow. On average I'm getting about 15 with no trailer and feathering the gas pedal to keep in v4... I'm not sticking my foot in the floor board all the time to hear the k&n roar[emoji848]. I see a lot of you guys getting 16-19 with pretty much the same setup. I think I was getting better mpg without the k&n.

 

 

I average about 18, but my problem is trying to stay out of the throttle. Two weeks ago I got almost 20mpg on a tank, but I didn't go over 60mph, I tried again this week but was running late monday and tuesday the DIC is showing closer to 17 when on Sunday it was showing 21. I have Cold air inductions CAI, 33'' Duratrac, removed the front airdamn, trailer mirrors, magnaflow off road cat back.

My daily drive is 8 miles each way in city traffic, so I average about 16 - 17 mpg if I'm lucky. When I go on trips, I easily get 22+ mpg on the interstate going 65-70 mph.

Let's not forget the few asshats here that claim 25+mpg running 80mph; and the one that claims almost 30mpg.

 

You have an interesting handle. I like it, It fits perfectly.

Crew Cab Z71 5.3. Deep gears and a 4 X 4 with a lift kit and off road tires. Yea, your K&N has nothing to do with your mileage. Isn't hurting it anyway. I run one too. Replacement type.

 

I'm the a$$hat I believe 'dork weed' was referring to. :dunno: They put the same sticker on all the Silverado 1500's making one distinction only. 2WD or 4WD. 24 mpg and 22 mpg respectfully. that is highway mileage. Dollars to donuts says the one they tested was similar to mine. RCSB 4.3 WT1 2WD and then guessed from there and guessed WRONG. There is a half ton or more of weight difference between yours and mine. A liter in motor size. Your run a good deal stiffer gear ratio. (Z71) Are 4WD. Run off road tires. Lifted. I run a bed cover. That's the difference in trucks in a nutshell.

 

Drive wise, even if you are prudent, if your trips are under 35 miles in the summer or a hundred in the winter (between trips where you completely cool down) your never fully warmed up. (watch your trans temps as an indicator not the water temp) If those trips are urban then there is a great deal of interruption in those miles. Lots of accelerating the load and even if done mildly they take a fair amount of fuel. Late to initiate stops waste huge amounts of fuel. Scares the crap out of cross traffic too and kills the brakes. Stop lights/signs, trains and traffic patterns kill mileage as well. Weather and terrain have an effect. And lastly I'm here to tell you that the difference between 50 mph and 70 mph is HUGE. Even in my rig. There is a wall you hit about 53 mph where the air over the truck looses the boundary layer and the truck becomes like pulling a fish net though molasses. If I run 70+ into a headwind of only 15 mph I can drag mileage down to under 17 mpg. Same trip at 55 nets 24-26+ mpg. I can run 65 mph with a tail wind on the Interstate and pretty much get 28 mpg at will. Slower speeds have netting a high of 32 mpg for a full tank of over 500 miles on my tiny teeny 26 gallon cell. 30,000 mile average over 10 months is a dead 26.0 mpg.

 

Now, all that said. I an not implying you have all those habits but you know which ones apply. Use what you can and ignore as much as you like. I don't buy your gas. :seeya:

I'm running KO LT285/65R18

I don't see a recommended tire pressure on actual tire. Just max of 80 psi

2.5 lvl kit

The 21 miles per gallon was in the hill country. I guess my truck really likes Central Texas

It's going to be very close to your original sticker pressure in your door jamb.

Good looking rig. Getting 15mpg with a level and 285/65R18 sounds about right. I get about 17.5 average per tank with a level and smaller non-LT tires than yours. I expect when I go to 285 or 295 tires, I will be in the 15mpg range.

 

Post up some more pics of your rig with those 285s. I'm torn between the KO2s and the Nitto RGs.

I've got the regular KO's ( old style A/T) I saw the KO2's today and they look pretty awesome and pretty sure that's what I'm getting next. Nittos may be a little too aggressive for all the hwy driving I do

6.2 8spd CC 4x4 I am seeing about the same mpg on this almost identically equipped 17 as I did my 16. Around 20.5 mpg average over 19,000 miles on the 16 and currently right at 21 mpg over 1500 miles on the 17. It really is mostly driving habits that produces the good mileage, I just like driving like a grandpa because I can. I know that if I wanted to I could burn over 90% of the vehicles on the road. I could probably take the OP's truck and wring out around 19 or 20mpg easily over several thousand (pretty boring) miles. So OP just drop it off with a credit card for fuel and I will run it a few week or months to see what we can get mpg.

We can trade. I'll pay for gas in your truck and you do the same for mine.

    • Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions? 
    • 2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!  
    • Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?. 
    • He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it. 
    • I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
