Hey Fellas,
I currently own a 2013 Ford F150 4x4 Super crew 3.5 Ecoboost with 3.31 gears, which I bought new. I like the truck. I get about 21ish MPG highway. The air conditioner is really weak! I used a meat thermometer to measure the vent temperature, which is about 50 degrees. My Wife's 2012 Chevy Equinox's vent temp is 39 degrees. Big difference when it's 95 degrees outside. The dealer drained and refilled the A/C system three times. Not much difference.


My question is for the 2015 Ford F150 3.5 Ecoboost owners. What kind of 'real world' MPG are you getting on the highway. Also, how is the air conditioner? Vent temp?


What kind of highway MPG are the 2.7 Ecoboost owners getting on the highway?


Thank you.

 

Thats horrible my ac works great even in dead of summer here 110 plus......I've been eyeballing some '15s as well

 

Mine is too new to say for certain, but with the 3.5L EB and 3.55s I'm seeing around 22 on the highway at 70 MPH. I'm under 1,000 miles though and have only filled it up once.

My '13 had the same engine and 3.73s with the max tow package and was very hard pressed to see 20 MPG.

 

We've only got about 3600 miles on our '15 crew cab, long box, 4x4, 3.31, and 3.5L EB. We've been getting between 18 and 26 MPG, but that's "indicated" on the Lie-o-Meter (LoM), which is about 5% high by my hand calculated measure. Is yours measured or the LoM?

Can't say about the A/C, but ours is cold enough by North California standards.

 

LoM, I've only filled up once. LoM said 17.3, hand calc was 17.1. That was mostly highway with ~100 miles towing some light things.

 

I have about 4000 miles on it, no towing and all easy driving, and I'm averaging 17.5 on a 3.5 EB with 3.55's and Max Tow. That's real, hand calc'd MPG as opposed to the LoM, which is showing 18.4.

 

Can't tell you about the 2013, my 2012 would freeze you out of the cab on a ninety plus day, we will see how the 2015 will do, my old truck would get on a long term average about 17 mpg, over the last 8000 miles, about 18.2 mpg.

 

My MPG is from the LoM. 😊
I hand calculated it when it was new. The LoM is about 5% higher.

 

I track mine with a cell phone app. Not sure how accurate it is compared to say, hand calculations. I haven't paid much attention to the LoM. in 2447 miles, I've averaged 17.48. I have a CC SB 4x4 3.5 eb, not sure of the rear end gears off the top of my head. I've also done some towing, and used 4wd across the outer banks, here in NC with some pretty strong wind and rain, where you almost couldn't see the road through all the sand. I'd say the AC worked fine, though I haven't stuck a thermometer in it. It's only around 60 here I beleive, so I'd suspect it would be down somewhere in the 30's if I measured it at the vent. If I get chance to do that I will this afternoon, especially if the sun comes out.

 

I have a 2013 5.0 4X4 and my A/C doesn't blow that cold either. That is one thing I wish was better.
