I have now read hundreds of posts about MPG's and the common theme seems to be that the 3.5 EB gets the worst mileage, and the 5.0 gets just as good milage as the 2.7 (21-23 mpg tops). What is goin on here? I don't them think everyone is lying. What is the point of the 2.7 if it gets only 1 mpg better than the 5.0 in many reports, and even worse milage in a substantial amount of responses?

 

With about 500 miles on my 2015 5.0 XLT 4x4, I'm getting a little over 20 mpg. My driving is approximately 80% highway and 20% city. I haven't done any towing yet.

I got the V8 because I worried about the longevity of the turbos.

Plus I liked the sound.

 

Honestly, I think most people don't know how to drive the turbo motors. I'm not saying to drive slow, but they don't need reved up to get just as fast as other vehicles. People tend to get in habits on how hard to accelerate, and it has little to do with speed or actually acceleration, but rather the acceleration "feel". Because of this, folks keep hitting the gas harder than they need to and mileage goes down. Why make the 2.7? Well because on paper it's good. It's best in class gas motor. It shines more in town because of the shut off, if our samples don't represent that then we are ignoring its designed value. It can be more efficient than the other motors if driven right. While I don't care about fuel consumption, some people do. Thats why some people get 10 mpg better than I do in my Fiesta. The 3.5 IS more efficient and powerful than the 5.4 it replaces. It was never meant to be a fuel sipper compared to the overall line.

I also think perception matters. I don't think people are lying, but if you get a 2.7 you expect great mileage. If you get a v8, then you don't. People comment on something different than their expectations. So V8 folks comment with how happy they are and 2.7 folks comment on how they expected more. The folks getting what they expect don't say as much.

 

This is what I am talking about. I see reports of the 2.7 getting 16-17 mpg.

 

I want the 2.7 but I also want an Screw 6.5' bed so I'll be getting the 5.0 unless I go Scab 6.5

I live in rural northern MI where it seems highway drivers are doing 50-55 everywhere. I got 24 mpg with a 2015 5.0 for a few days on my run to work and back. From what I've read, the 2.7 would get me 28 mpg driving Grandpa style up here after a short break in. Not many are willing to drive that way.

 

Highest I have read for the 2.7 is 23-24 mpg, and that has even been rare.

 

Over on another F150 forum there's a huge 2.7 mpg thread where "matt" has been documenting hand calculated 28-31 mpg over 9000 miles or so driving like me. I'd link it but have not read the rules here and don't want to violate. Won't take you long to find it.

 

Gas is $2 a gallon or less these days step on the go pedal and have some fun ........save the complaining for when it's pushing $4 a gallon

 

$2.49 here today. $3.69 one year ago and have seen $4.99 in the not too distant past. Anyway, I'm not complaining, I'm praising the potential of all these engines in these heavy boxy trucks.

 

It's nothing short of amazing the engines all manufacturer's are making these days......it wasn't that long ago you'd have to do some serious aftermarket beefing up to get the horsepower these modern engines are cranking out and you can bet the mpg wouldn't come close to what's going on now.......I just think people expect to much when in reality theres never been a better selection of trucks to buy from all the manufacturers

 

I had a 1986 F-150 XL 4x4 with the 300 I-6 and 3.08 axles. The truck was a Reg cab and weighed 3800 pounds. The best mileage I ever got was 17-18 at 65 mph. The 300 mated to 3.08's through an M4OD transmission is a pure gutless turd.

The point? Be happy with our choices, they are amazing when compared to trucks of even 10 years ago.

 

There's no rule against linking to another forum as long as it's relevant to the topic at hand.

 

Yep................

 

I'm getting a solid 17.5 MPG out of mine, with most of that being highway at 70 MPH. I drive like the grandpa I am and use the cruise extensively. But, it's a truck and will haul or tow anything I care to load or couple up. And, the 7.5 miles of towing I've done, bringing our 6000 lb boat/trailer combo home from the lake, proves it is quite capable. I'm pleased overall, but am not getting the MPG I was led to expect.

 

OK, here's that link. It can be skimmed if you don't have an hour of your life to sacrifice. Seems mileage improves greatly around 4000 miles.

For me I think I'll go with the 5.0 but the 2.7 is capable of more with a gallon of gas.
