New truck MPG question

So I recently bought my first ever F150. 2014 FX4 Ecoboost appearance package.

Love this truck.

My question is about gas mileage.

I have about 1200 miles now on the truck, and it is pretty bad.

I just returned from my first trip to the lake pulling my 20' bass boat.

About 100 miles each way, mostly highway (Ohio,very flat roads) never going more than 2-3 over the speed limit.

10.8 MPG for that round trip. Truck is getting 12.9 overall since new.

My question is will this improve as I get a little more miles on her?

It will improve a little bit but nothing earth shattering, you have to realize you have not 1 but 2 turbos pumping extra air into your engine and since an internal combustion engine does not run on air alone you must mix something with it, can you guess what?

.

Iv got an 2014 XLT and just hit 17 MPG.... AT 3200 MILES.

I was not expecting 20 MPG or anything, but 12.8 without boat, and 10.9 with?

I am not sure there is any truck in the class of the F150, that would get worse mileage than that. I might as well have gotten the Raptor.

I pulled in June a Ford Fuson on a tow dolly from Florida to New Jersey with the bed full doing 70 MPH most of the trip and got 16.5 for the complete trip. I would think that you have a problem. My truck is a 2013 ecoboost and I only have 3700 miles on it. The one item that I have found out is to use the cruise control any time I can. I cannot get the good mileage without using the cruise.

Excerpted from the 2014 F-150 owner's manual .....

Calculating Fuel Economy

Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine’s break-in period); a more accurate measurement is obtained after 2000 miles - 3000 miles (3200 kilometers - 4800 kilometers). Also, fuel expense, frequency of fill ups or fuel gauge readings are not accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least 3 to 5 tank fill ups, fill the fuel tank and record the current odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For Metric: Multiply liters used by 100, then divide by kilometers traveled).

Keep a record for at least 1 month and record the type of driving (city or highway). This provides an accurate estimate of the vehicle’s fuel economy under current driving conditions. Additionally, keeping records during summer and winter show how temperature impacts fuel economy. In general, lower temperatures mean lower fuel economy.

11 mpg towing a bass boat is a smidge low but not that bad. Any truck pulling a bass boat will get 10-14 at best unless it's a diesel, then maybe a tad higher. Overall you mpg should average 14 for heavy city driving to 18+ for mostly hwy driving. I'm at like 18.2or maybe a couple tents higher over truck lifetime with Eco. Last Eco was lifetime around 17 including pulling an 8k lb boat thousands of miles. Getting low 10s mpg during those runs at 72 mph. Maybe buy a tuner, will help with power and could net you 1-2 mpg more.

My 2014 XLT 5.0L just turned 3200 on the OD after a 2200 mile round trip MI to NC and back. Averaged 19.5mpg and that was 70 mph interstate, stop and go in the construction areas and 200 miles of slow driving on the outer banks including some runs in deep sand in 4wd. I'm pretty happy with it.

I've owned the 3.7L, and now the 5.0L. Both took approx. 3000 miles before they started showing decent mpg's. From reading here the 3.5L is the same. Give her awhile longer, and you should see a good improvement. Also, your driving habit will greatly affect your mpg's. With more experience comes more gas mileage, especially with the turbos.

I have had the same experience with a 2014 FX4 Ecoboost with the 4.10 Electronic locking differential option. Nearing my first 1,000 miles and I am exactly at 13 MPG for mostly surface street driving and a little freeway driving.

Does it get any better with a few thousand more break in miles or is this reality?
