I think my truck is on the low end of the spectrum when it comes to the 14s. I'm getting 12-15 in town stock and 18-20 highway at best. It's more like 13 city, 17 highway.

Mine too. Drives me crazy seeing people on here getting 18-24. I have a stock setup and drive mine like an old man, and I'm stll not getting what I expected (or as advertised).

I've driven allot of long distance road trips and have never hit anything near 24mpg. I think most of these high numbers you see are only small portions sample sizes or "best 25/50 miles driven. I only count mpg based on what I drove on that full tank. The highest I've ever averaged for the full tank is 20.5mpg.

I agree, I hit 25.3 on the last 50 reading on a trip a couple weeks back. The 25.3 was in a slower speed zone (60mph) and had a lot of downhill and was flat or very small grades going uphill. I set the cruise at 60 just to see what it would get. Adding in the rest of the highway with long uphill drives and long downhill drives, I'd say it was closer to 19-21ish overall with the cruise set at 73mph. That was all stock with a 5.3 and 20's. I'm at 17 for my lifetime average right now with a whopping 2090 miles lol. The average seems to be getting less the more I get used to driving it like a man and not a gramp as well.

Joelatkinson95, I would love to see some more pictures of your truck. Looks good and I am interested in the 3.5

to get the 23.8 on flat ground at 67 miles per hour I fixed the gas pedal flex and am incredible light on the pedal.

it is extremely difficult. The cruse only gets 21. I have to manually control it, letting the truck roll down inclines so it

can get up the next small incline without pressing on the gas more.

 

Its like a game, I watch the mileage the entire time. If I don't, it drops quickly.

My wife thinks I am nuts watching it that closely.

 

She drove the truck less then 5 miles and dropped my average down to 12. Took me two days to get it back up.

These trucks will drink the fuel if you let them.

 

68 it will drop, 64 it will drop. My truck has to be at 67 mph to get it.

at 32 mph I can get 28 on flat level ground.

pure gas always helps get better mileage for me. Most places only sell gas with 10% ethanol and it brings down the mpg.

The highest I have ever got was 15.6. I am about 60/40 city though. I understand that city driving is worse, but to be 3 mpgs worse, at my best, then what city is supposed to be rated at is a joke. My last tank I was at 13.1.

My "best 25" is 21.8 "best 50" is 20.1, "best 400" 15.1. 3500 miles and my mileage gets worse every single fill up, like I said my last tank was 13.1.

I also watch my mileage the whole time (and my fmaily thinks I'm nuts and laughs at me the whole time), and drive like a Grampappy. Coast when ever I can, and drive 65 (70 mph speed limit) on hwys, 45 (55mph) on country roads most of the time. I've never drove like this and it's starting to not be worth it, I wanna ripppp!!! :driving: lol

I wont keep doing it, just wanted a good base line to compare each mod.

For those who talk about coasting or downhill. I use a round trip.

 

I get better millage at 67 then 45. I have not found a perfect spot in a 55 mph zone.

Have not driven many of those.

 

For a quick test it is 15 miles one way, I check average there and back.

For long test it is 65 miles one way. I average there and back.

 

I am not picking all down hill.

 

My 2010 got 14 mpg and it drove my nuts. I want to be darn sure I know what causes this truck to get bad millage if it happens.

I think a lot of people are missing that I am a 2 door. I'm sure the lighter weight has some effect.

I'd like to find that magic number for the 55mph highway I travel to and from work on m-f. Problem is it's got about 8 stop lights on it and tons of traffic, so the cruise is usually useless. Basically like city driving but a little faster haha.

cruise lowers my millage slightly. I have decided it is cause it slows the truck down when going down an incline.

If I am driving I let the truck roll and get better numbers.

 

If you not in town, you might not have much traffic.

I have found that if I triple my normal stopping distance when coming up to the light, I can make up any lost fuel millage when taking off.

I let the truck start coasting as soon as the light is in sight, when no one is behind me. This gives me about the same distance at 99 mpg

as I get 6 mpg when taking off. Thus not effecting my average.

 

Yes... this is going to an extreme and I wont do it all the time. But its kinda like a game at the moment.

Remember, I have had my truck about 15 days. But I have 1800 miles on it.

I agree, I feel like I'm playing/trying to win a video game with the DIC while I'm driving still haha.

Read up on 'hypermiling'

 

Hmm... did not know there was a term. I figured all that stuff out on my own.

I was thinking about pulsing yesterday. I kinda figured that you could speed up and cost

and get better millage then just going one speed. Again no idea there were terms.

i have just been playing with my last few cars to get better millage when gas was $4 a gallon.

    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
