It is a 2013 and I think it has the new 5.0L. It is a 4X4 four door short box with a cover on the bed. The trip started in Colorado Springs. The dash picture looks just like mine. I need to check the sticker for EPA numbers. Will check and post numbers. Is there any other info from me that may be useful? My 2 big things are the bad MPG and the service person saying that the readings won't be accurate until after getting 8K - 10K miles on it.

 

Mine is a 2011 Fx2 SCREW with 3.73 cogs. My lifetime is 17.2. Even with the 4x4 you should see decent mileage from the getgo.

 

Very happy, Freeway can get 24mpg. Mixed with 50/50 freeway traffic it's reporting 21.4

800 miles, supercrew 4x4 3.55 axel:

EPA rated 21/15

 

I have a 2012 XLT EcoBoost SuperCrew. No mods. 3.31 Regular Axle. Stock 18" wheels and tires.

Currently, I have about 10,000 miles on it and the computer says I'm averaging around 15.2 mpg.

This was not the case before my first oil change (I've only had one so far). I was averaging 18.1 mpg combined. I was shocked when the mileage just plummeted after my first oil change. I mean, it was almost instant. Picked the truck up from the dealer, reset the computer, and watched it struggle to stay around 15 mpg combined.

My driving habits haven't changed at all really. So I'm wondering about a few things that I'm hoping you all can help me out with:

1. Does anyone know what kind of oil these trucks ship from the factory with? Synthetic Blend or Full Synthetic? The oil change I had done was with a Synthetic Blend.

2. Is there something I should be doing to calibrate the mileage computer better and ensure accurate readings?

3. What is the best recommendation for tire pressure as it relates to mileage? I've always been a stickler for keeping my tires exactly to the recommended pressure, but I'm willing to try something different if it'll help increase fuel efficiency without sacrificing safety.

4. I would prefer to change my own oil, as I do for my Mustang and Explorer, but I've read that changing the oil for these EcoBoosts require special tools/equipment, and can be a very messy affair. Can anyone definitively shed some light on this for me?

5. Any other maintenance tips to help improve fuel efficiency?

Thanks everyone. Appreciate any help or advice you can offer.

 

I've had my 2013 F150 limited for only 1 week. I take a back road to work with hills and winding roads. I set the cruise to 45 mph and get 17 mpg. This morning I replaced the factory air filter with a K & N filter and got 20 mpg.

 

Does being in overdrive all the time help or hinder MPG?

 

It may not be a snowjob, but it is incorrect. You can just calculate the MPG yourself in any case. For one fill-up, your calculations might be off a bit, but if you average a few of them, you'll be pretty close to whatever you're getting overall. For years I've been in the habit of using Trip A for tracking miles since last fuel stop and Trip B for anything else.

As others have noted, mileage is a bit worse in the winter (that's my experience, too--up to a 10% drop).

 

Yea, I'm fine with my MPG.

 

My EDGE programmer got my MPG up. Plus if I want to do some doughnuts, "Extreme" mode helps out a lot.

 

If tuners improve economy so much why aren't they OEM?
