2019 worse mpg than 2012?

[mcaveman]

I’m getting about 12-13mpg with my 19 Limited, use to get 13-14 with my 12 Laramie both hemis . I know it’s a truck and all that but is something wrong with my new truck or does that sound right ?

To be fair both trucks mainly all city driving .

To quote RHeller above:
"same gears? both same cab configuration?" Current mileage?

 

[Uncledude13]

Not sure about the gears but the rest is all the same 1300 miles

Different gears could definitely have an effect (3.21's vs 3.92's). How much of a difference are we talking from your old to the new for the mpg lost?

2019 2" MOPAR Lifted Laramie....3.92 gears.... 35" tires.... Borla Touring Exhaust... PULSAR programmer and forced induction vararam intake

I am averaging 13.8MPG

Sometimes my 3.5 TT F150 Lariat is missed hahaha

2016, 3.92 gears, 2.8/1.5 lift, 33” oem size AT tires. I was averaging 14.5. I dropped a K&N filter a few days ago. It’s now reading 13.5 but I think I’m just punching it harder since I got it... Either that or the fuel management system is spitting out more fuel with increased air flow?? But other people say they gain 1mpg, so I guess it’s my lead foot lol.

jrod, I also dropped in the K&N filter and thought it will help increase MPG but not so sure. I will give it some time and then drop the OEM back in and check it out again. I don't have any good data to compare with yet.

I am thinking about unhooking the battery to reset the system as others had suggested and allow the computer to relearn the new air/fuel mixture. Not sure if that will work either? Some have said it increased performance after they unplugged but there is not a lot of information on the subject.

I'd like to hear from others if they have done that.

My 18 Longhorn gets 14.5 mpg in the city.

 

[RammerHarder]

Give it some more time to break in, it should get better.

I played around with it some more and managed to get more MPG’s. I posted more about it here.

I have no clue what MPG I am getting. I assume it sucks compared to most other vehicles since it's a huge truck. Lucky for me the MPG doesn't matter, short of something stupid like 1 MPG.

2 MPG worse in 15k miles of city driving, assuming 10 & 12 MPG:
10 MPG/15k miles = 1500 gallons
12 MPG/15k miles = 1250 gallons
@ $2/gallon = $500 per year. And that's a lot of city driving in a year.

I would assume the MPG is worse on these trucks when they're brand new, and that it gets a little better as the truck breaks in. But I could be completely wrong.

My 2019 4x2 gets 24 on a trip, 20 mpg city

I drove a 2012 Longhorn, 2015 and 2017 Limited and now 2019 Limited E-torque. The biggest thing I see is that the 2019 lie-o-meter tells the truth. Hand calculated mileage is almost identical. The first 3 trucks were driven a combined 313,000 kms and the 2019 only about 12,000 so far. The 19 is getting marginally less but 8000 kms was with between 1000-1500 lbs in the box in mostly cold and stormy conditions in western Canada. I don't do much city driving. If you don't calculate mileage you will be very disappointed with a 2019. These 4 trucks have all been better than my 2007 SLT and 2010 Laramie. (221,000 kms combined)

I highly recommend installing Fuelly on the phone. Nice being able to chart over time. I get around 19 commuting in town and 17 on the highway.
My 16 Longhorn EVIC is inflating my #'s by about 10%. Last night the EVIC said 21.8 for the tank, actually it was 19.6!

I snap a pic of every fill-up, here is last night's. I wish I could get the 700-mile range that pops up on a fresh tank!!!

My 1-ton diesel averages 14.5 mpg around town which is why I usually take the Prius that gets 45 mpg for my errands that do not require a pickup truck. If I do 50% of my trips with the Prius my "fleet" average is 30 mpg.
I can also more months between oil changes and suspension lubrication and my filters last longer.

K&N filters are not going to provide a gain over the factory filters unless you are driving on unpaved roads all the time. Important to also try to understand and appreciate that an air filter as with a fuel filter is least effective at filtering when it is new. It takes time for loading to take place and in the interim more particles get past the media.
