How did you setup affect your milage/drivability?

 

That's awesome. You get to have your cake and eat it too. Several years ago my wife had a Ranger, but it was a four banger. It got good gas mileage, but couldn't haul very much. It was more for hauling bulky things than heavy items. We traded that for her Explorer. It could handle heavier things than the Ranger, but it was a bit limited on the bulky things. It got good economy, at just a little more than my F-150. Now with this truck I can haul heavy, bulky things and I get decent economy.

 

I could do a 10 mile run with my EB and get the lie-o-meter to read 40 mpg on the right stretch of road, just isn't far enough to get a legit number.

 

The dealer installed those items, so I have noithing to compare it to, but I can say that it's a lot smoother of a ride than I expected it to be.

my 02 F150 4x4 with 5.4 used 20 liters of fuel for every 100 kilometers, and I ordered this truck from the factory and babied it from the start.

No matter what I did, it aberaged 12 MPG. (I'm pretty sure that's what 20 liters of gas per 100 kilometers equates to.

Yesterday I drove from Kingston to Syracuse, NY to get my bedrug and ARE lid installed, and the truck averaged 11.9 Liters per 100 kilometers, that wawith the cruise set at 65 MPH.

It's smooth, handles well and has plenty of passing power when you need it. I'm very happy with this truck and am looking forward to see how it tows.

Thursday I'm picking up a new 2012 Keystone 24 foot tt (actual size from pin to bumper is 29, 4'. I'm hoping it does a good job of towing.

 

I was just curious. I wondered if the flat torque curve of the Ecoboost would be less effected by taller tires than the 5.0 V8.

 

That will be an interesting question.

My wife now has a '12 Explorer with the 2.0 EB motor. It drives awesome but it takes very little additional throttle input and the instant mileage drops quickly. I have to believe that the turbos are controlled to eliminate the perceived "lag" and therefore mileage may suffer since the motor may not create much torque without the boost. If this is somewhat true, I would imagine the extra torque required to turn taller tires would put the turbos into a "boost" state to compensate and therefore reduce the mileage.

Just speculation on my part, but I am about to order a truck and will likely go with the 5.0 as it seems more folks are consistently getting better mileage than the group reporting with the EB.

 

A lot of it has to do with driving style and terrain with the EB.

I live in the Midwest and do a lot of flat open road driving, my last 5 fill-ups have averaged 19.6 hand calculated. I also drive 2-3 mph faster than the speed limit and have a soft foot. Filled-up yesterday and hand calculated 20.8 (best to date, 380 some miles). Life of the truck I am now in the 18.8 range with 7300 miles on the clock.

It'd be neat if I could have a 5.0 in the same set-up and see what I could mpg wise. I bet it would be very comparable.....

 

I think you are probably correct. I get a little better than that with my 5.0. even in hilly East Texas, but I have a 4x2 with 3.55s. I think it would be close if I had the 4x4 and 3.73s.

 

I'd love to see what I could get with a 2wd EB and the 3.15 rear.... I bet I could eek 23/24 out of it regularly....

Jay, I am running 3.55's, probably could have gotten away with the 3.31's really, but I have only ever had 3.55's in my F-150's.

 

Touche on your lie-o-meter comment but mine sounds like a truck and not some space car from the Jetson's On the same 10 mile stretch as before going at faster speed like 70 mph it drops to 20.5 mpg and at 75 mph it drops again to 18.5 mpg.
BTW I just made a 200 mile road trip and funny how it still averaged over 22 mpg at 65 mph. IMHO 10 miles is enough road to get a base mpg. I don't live in the hills

 

That is all very similar to what I get with the 5.0. I don't drive hard, but don't baby it either. The cruise will be set at 70 on the highway and I will go faster to pass when needed. Over the trucks life, I have averaged 19.5 for 25,000 miles. This is probably 80% highway with hills and many small towns and 20% in Fort Worth. I get about 17 in town and will average about 20 to 20.5 for a week. The absolute best I have gotten is 23.4 for a about 85 miles of interstate with a few hills, but mostly level. What I have found that kills the mpg is idling, wind, and continual climbing, even if gradual. Going into a headwind, even a slight one will knock off at least 1 mpg.

 

Glad someone else is seeing the same results as me

 

A side joke on myself, to prove I don't baby it. I go down this little rural East Texas highway every weekday. Got a ticket last week for doing 69 in a 55. This is the exact spot.

 

If you want a larger sample than a few people posting on a forum, go to fuelly.com and you can see what mileage people get. My 4 x 4 ecoboost is averaging 11l/100km or 21mpg. Had a 5.4 before and doing same driving I got 15mpg. Ecoboost is great in my opinion. One observation is that I notice mileage gets better after warmup which takes 15km or so and I drive 30 hwy km to work. I think short trips in the city the mileage would not be as good.

 

A big part of that is becuase it runs very rich until warmed up. So, if you are doing short trips, you are probably just reaching the efficient stage when you shut it off.
