Short little trips can leave me with a 16 or 17 mpg on the gage, but it always averages out to about 12 mpg, so

These can’t be HD numbers?!

 

Sure they can.

 

Mine are better than that. 

34.1

29.8

24.4

Yes, that set was in the mountains and I don't expect a repeat.

 

Any day when its' not windy I can take you on a drive on a flat ground out-and-back trip and get the average at or above 25.  Even on winter fuel.

 

But that's at 55-60 mph, not at 75-80.

My 2015 WT1 doesn't have a resettable at those increments. Only a resettable tank average. Often over 33 mpg. It lies. 

 

Hand calculated: 

 

Over the trucks 107,000 miles the average miles driven per tank has been 391 miles. Average fuel load has been 14.2 gallons.

So 27.57 mpg life time. 1 standard deviation is about 2.25 mpg for a range of 25.25 to 29.75 mpg lifetime. Best single tank of a least 400 miles has been 33 mpg and worst about 23 mpg. For only the summer months of 2019 (180 days) it averaged 30.15 mpg.

Yeah, you quoted me last month saying the same thing. I didn’t reply because I wasn’t buying it then & I’m still not buying it now. [emoji3]

 

I guess if you’re coasting down the mountains it’s possible...

L5P

 

28.7 - 25 miles

26.0 - 50 miles

22.8 - 400 miles

10,000 more miles, and quite please with L5P. I live in the Midwest, so no, I didn’t glide down any mountains.

 

25 - 31.8mpg

50 - 28.9mpg
400 - 22.8mpg

Damn some of y'all are smoking some good ****** if you believe these mileage claims.

When you spend $60K, you think everyone is gonna stomp on the pedal all day long, day in and day out? Nor does anyone put their truck on blocks and runs it for 400 miles. Believe what you want, it's not like anyone is getting a f'n ribbon in the mail for their MPG.
Only Ford sends out second place ribbons from what I heard.

18.4 on the 50 mile average.  75 mile commute to work, flat, 2 lane roads.  I can usually hit between 16-17 pretty regularly.

This was the 2018 L5P just before trade-in

    • 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?
