no complaints here, havent towed yet though

 

17.4 mpg on my first tank of gas. 50/50 city/freeway, and I was flooring it and speeding on the freeway more than normal.

3.55 rear end.

 

22 on hwy and 16.5-17.5 on mixed and 16-17 city only.

This was prior to my 2" level and new tires though. We'll revisit this after a few tanks.

 

Only 4K miles on my 13', but around town I get between 15-17 mpg (depending on how I drive, red lights & traffic). Drove the truck from NC to GA and back on I95, cruise control most of the way at 73mph and I averaged 20 mpg. I very pleased with the mileage overall for this big truck and don't expect anything better, but if anyone has someway to squeak out a couple more mpg's...please share :-)


2013, F150 XLT, SuperCrew, HD/Max tow package, 3.73

 

paired with the Edge tuner shell premium gas gives me the best mpg.

 

Use imperial gallons.
It sounds better.
lol

 

I have a 2004 XLT CrewCab 4x4 with +/- 140000kms (87000 miles) and I average 14.1 MPG (17 MPG imperial 16.8 L/100km).
I've changed the plugs and added a k&n air filter.
My lowest was +/-7.5 MPG (9 MPG imperial 31.36L/100 km) towing an 8x16 trailer while going moose hunting...
Total rig grossed out at a tad over 12000 lbs... I checked the weight at a closed DOT scale on my way home.

 

Okay, admittedly, the "shiny" hasn't even worn off yet, but so far this picture makes me a happy camper!

 

Just got back from a 400 mile road trip, avg 21.5 for the trip. Cruise set @ 60 mph, 1500 rpms.

Midwest MPG Update

It appears midwest and northern states winter blend fuel (also 10% ethanol) as well as the
bitter cold air plays HELL on EcoBoost MPG's. I got 17.5-18mpg driving it home 45 minutes
on back roads the week I bought it Dec 2013. I have no idea what fuel the dealer used to fill
the tank but it obviously was not winter blend.

On my next fill up winter blend apparently was out and I was getting 12-13mpg city and only
15-16mpg highway. I even reset my tripmeter while on flat lands expressway doing 65mph and
I got 15.x mpg. It's been this way since the week after Christmas til the 1st week of March 2014.

So now that March 1st has hit, I guess some of the stations have already been getting Summer
blend fuel in. My MPG's jumped up to 18.1mpg on my 45 min drive to work on regular suburb streets.
Most of it was stop n go too with 35-45mph speed zones.
