Gas mileage ?

All about towing and tow vehicles

Re: Gas mileage ?

Postby Camp4Life » Thu Jul 13, 2017 11:54 am

Wishing that I had been able to build my TTT this year, but for health reasons I decided to pick one up that I found for a really good price.

My 2015 F-150 with 2.7L Ecoboost engine gets me 26-29 MPG on the highway.

With my camper, I get around 9.5 MPG :(
The camper is not very aerodynamic, and weighs in around 4500 lbs. But it's due to go on a diet as I get rid of a few things that I don't need : hot water tank, heater, air conditioner and possibly entire bathroom including black water tank if the wife allow it. I'm also going to drop one of the two propane tanks since it's overkill. The fridge hardly uses propane and we don't cook inside.

If I might suggest: A cap when towing and
perhaps an air wing at the end of it.

Its the frontage 'Air Dam' that kills things.

Also at what speed are you towing?

Wow that trailer probably weighs as much as the truck if not more.

I forgot ford put such a sad little motor in some F150s.

Btw weight vs wind resistance is a fair bit off.

If your where its basically flat terrain then its mostly wind resistance which still isnt a big deal till speed above cruising around town.

Highway it plays a good sized part but weight becomes an even bigger issue when you have hills and mountains to deal with. Towing up hill with a vehicle that doesnt have a sizeable amount of torque will loose around 50% of its fuel mileage. No different than a noticeable fuel mileage loss between just the driver versus full of adults in a vehicle.

My Tacoma gets ~21-22 without the trailer and ~18-19 with. Trailer weighs 1640 lbs with probably another few hundred pounds of gear in it and a few hundred lbs in the bed as well. Have to tow in 3rd on the freeway (4 speed auto) because the little 4 cyl engine won't maintain speed doing 2000 rpm at 60 mph with all the weight.

Now that this truck is no longer my daily driver, I wish I had the V6 as I would gladly give up a few mpg for more power.

not to say that I am a Ford fan-which I am not, BUT "....sad little motor in some F150s" ? that 'little' motor is why that BIG full sized truck gets such good MPG with no load and the question should asked, how can such a "small" motor even be able to tow such a heavy trailer along with powering such a big truck?? 2.7 liters equals about 165 cubic inches - YES that is a SMALL motor!!! But believe it of not, it produces about 325 HP and a lot of torque to go with it - if I remember right it has duel turbo's on it and yes, when you need or use all of it's power when towing the gas mileage drops a whole lot but no matter what size of motor or brand of vehicle you have when towing something that heavy/air resistance your mileage is going down!!! a lot!!!. I am still total awe of the power being produced by the Ford's nowaday engines along with them, for the most part being so dependable. They seen to be holding up just fine so far. Next time you see a Ford Explorer police vehicle - and there are a lot of them!!, think about what is under it's hood - a 3.5 liter V-6 producing 365 HP and 420 lbs of torque - that's only about a 213 cubic inch motor!!! and some of the newer versions of this motor are over 400 HP now!!! ... Sad little motor ???? :thinking: (Sure glad my brother-in-law does not read this forum-I would NEVER hear the end of this if he found out I am defending FORD ;) ) :beer:

Im not a specific brand person anymore. Ford and jeep growing up. Becoming an ASE tech, messing around with imports and such I learned a lot. And since I still do it on the side (helping friends that have a shop but they dont keep up with the advancements like I do, so I usually handle the newer vehicles)

Turbo motors in a truck that arent part of a diesel is just wrong. And almost 6000 rpm to get to that output. Thanks for making me look all that up, drove me further away from ford lol. And i really like the looks of the newer trucks. Not meant derogatory towards you in ANY way. First thought when i looked at the newer fords in detail now all I could think is Id have to burn my man card if i wanted to drive one. And right now we drive:

My work vehicle is a POS 1999 caravan short body thats a blueish purple (got it for $200, have less than 1000 in it total, bought it to haul mountain bikes and tools)

Wife has a 2007 Honda Odyssey (i let her think its hers, I bought it, shes getting her Sienna she wants probably this fall)

I kind of want a 4 door pickup but to have a real engine means older, no modern transmission or OHC/OHV for power and mileage. Not unless I want to pay half the cost of a nice house.

Trucks are going the way of the SUVs. Minivans drove moms to SUVs, which went from sport utility vehicles to useless, pretty looking urban kid haulers (with a few exceptions). Except trucks are turning into purely an "image" thing as well. Awesome numbers for a motor that belongs in a sports car. For DYI Dads that want to look the part. Again theres some exceptions.

I understand it and hopefully no one takes offense. To each their own. Just irritating that most vehicles are becoming simply luxury kid haulers that are nearly useless for the tasks they grew up doing. SUVs was offroad capable, rugged, outdoors off the beaten path lifestyle. Trucks is a haul or tow what you need to get the job done. Not look pretty, not under powered and built soft, meant to go to work, get it done.

I wouldnt be poking fun at ford if that motor was in a ford ranger or equivilant. Would make some sense at least.

When it comes to work load power, there is no replacement for displacement. But great mileage unloaded can still be had. Honda and toyota have been doing it for decades

Guess we all have our opinions and at least I do not put down other folks choices her. My 2012 F150 Lariat pulls my loaded converted CT trailer, goes in the woods with me, drives the sands of Cape Hatteras, holds my front mounted surf rods safely and conveniently, keeps my old bones comfortable and the heated seats soothe my bad back (need surgery someday). Turbo gas mileage is not so good, but I am at the stage of life where I say, so what? And yes, my eyes were open. I strive to keep up with no none of the Jones', but I have a TV which suits my wants and needs. I never burned my draft card and if I did have such a thing as a "man card" (I guess to go with my " man bag"....ha!, I would not be caught dead with one), I would not burn that either. If I want, I can drive and tow at all Interstate's speed limits. Trust me, the power is there, more then is needed. Ever spin your tires towing a heavy trailer?

Oh and afterwards, when I clean it up, it serves as my family vehicle carrying 5 passengers very well. Do not need another vehicle to serve that function. So what is the issue, really?

With my truck cab, it carries my "goods" dry and protected. Yes it could have a little more of a throaty sounds, but,then again, I did not buy it for sound, but for function. If I need the sound, I could get a Harley, but then again, someone would pick on my choice there too.

Buy what you want, but do not put my choice down.
Bob

  • That little 2.7 liter engine probably is fighting it's little heart out everytime you start from a stop, just to get the trailer rolling. Your truck is probably running on 17-18" tires, using 3.73 gears (at best), and gulping gas while the turbo screams away...meanwhile, my 2500HD Chevy, with a 6.0 liter engine, on 16" tires with 4.10 gears, slowly gets rolling, but doesn't gulp the gas until higher speeds. Unloaded, it might get 14 mph at 70 mph, but when loaded only gets 11-12 mph, regardless if the load is 2000 lbs (my TTT), or 4500 lbs (my wife's 20 ft Puma...much taller and wider, too). I've also towed to drag races, with 2000 lbs in my truck bed, and 7000 lbs on the open carhauler, and never dropped below 10 mpg, even at 75 mph. The key is that the smaller tires combined with the steeper gears keep my 6.0 liter engine in its' optimal power range, and the heavier rotating mass of the larger displacement 6.0 l engine keeps the "train a rolling", but also never gets great mpg, for the same reasons. So, while your modern-tech engine can pull a heavy load, it is best suited for lighter-duty, else the turbo has to force consumption of more gas to achieve what better gearing and larger engines do well, in moving heavy loads.
  • "There is no replacement for displacement", and "steeper gearing is better", both variants of "go big or go home"... were a couple of maxims I swore by in dragracing, that applied to going down the track, or towing my cars to it. New technology makes more power than the old tech did, using computers and the like, but, sometimes you just can't get power and gas efficiency at the same time...that's when the old, proven, tech wins, at least in my experience. No surprises. I'll never get good gas mileage in my old truck, but always get about the same, regardless of what I'm towing. It hardly notices any difference, no matter what's following behind. Just my opinion, yours may vary.

I wasnt putting "choices" down, just Fords. Sorry if you didnt see the humor. I figured everyone did when i admitted yo what we have for vehicles lol. Not very "manly" but do the job. And I used to own ford pickups exclusively. Ecoboost trucks is where i lost respect for them.

And a 2012 is still a truck. I am just not a fan of american made newer vehicles in general. Too many have gone the "Suburban Family" style and much of that makes a truck or SUV what they used to be is lost. But I cant help but poke fun at new Fords.

Sorry if anyone took offense to a little "ford" humor.

Well that was interesting. Just keep in mind that north america is the only place in the world where people think that an engine should be able to handle all its work load at an idle and you shouldnt tow with anything other than a 1 ton dually or bigger.
Anyhow, vehicles are designed to meet the expectations of buyers. The buyers of f-150's are commuters that will never haul any load, soccer moms, government/union employee company vehicles and commuters who use it to tow a boat twice a year.
Thats what their designed for. What they can do is different, but their made to keep 1 person comefortable with an empty or lightly loaded box. Thats who their buyers are. But just because thats what their made for doesnt mean they cant or shouldnt be used as a truck. Thats what the rest of the world would do with it.

Speed limits are 60mph where I travel and that's what I do. My 2nd trip netted better mileage and I did around 13 MPG. I must have been hitting some good headwinds on my first trip.

Truck weighs just over 5000 lbs, but it can still tow up to 8500 lbs. Like I mentioned above, I got better mileage on my 2nd trip so for sure I was going into some winds before. Funny enough, my truck tows my 7500 lb boat (weight includes trailer) easily and gets better mileage, but it's a lot more aerodynamic so...

And the 2.7 is twin turbocharged which gets my 325 hp and 385 torque. More than enough for my needs.

My tires are 20" for the record, and yes I have 3.73 gearing and the tow package. And the turbos create torque at low RPM. Most vehicles in Europe are turbocharged, and they've been doing it for decades with no issues (diesel and gas). No screaming when pulling from a start unless I put the pedal to the floor, but I would never drive like that when towing anyways, nor do I need to. If not towing, I'll just burn rubber if my traction control is off, so the tires are the only thing screaming lol

I rarely tow, which is why I picked this engine. But I do need the bed for gear, for both hobby and work and home stuff. And since I rarely do tow, I enjoy getting 26-29 MPG's for most of the calendar year save for the few days when I tow. So I'd rather take than any day. I have a 36 gallon fuel tank, and I've been on a trip a few provinces over and made it the 750 miles there on one tank. And that's the goal : Long trips, less stops to refuel, good mileage. So I'll take slightly lower towing mileage over mediocre everyday mileage any time.

I have 72k on the odometer so far and I've had zero problems with this truck. I've only ever taken it in for regular services. I tow my 7500 lb boat, and this trailer with no issues. The max I can tow is 8500 lbs but that's complete overkill for me especially since I'm getting rid of the boat. No other gas half-ton or larger can give me the everyday-mileage I get so I've got zero regrets with my choice. :beer:

For your needs that is the perfect Pickup. Sounds like a perfect light/mid duty truck while being comfortable and affordable to drive every day.

They are nice looking trucks, but sadly they have a ford emblem.

Jking, actually have me curious, maybe Ford did pull their heads outta their butts with these newer trucks.

Haha, yes this is my 2nd Ford. My first one was an early 80's Bronco that was used and in rough shape. Needed wheels, did the job for a year. I considered a pickup for a while but was never interested in F150's until 2015 when they changed the look and came out with the 2.7L. THAT's what caught my attention and made up my mind. That and doing 0-60 in 6.3 seconds on a test drive :?

So far so good, Ford has been good to me, and I might not go back to Nissan again...

Id never go to nissan personally lol. Too many problems with their transmissions (my in laws have been going through nissans about once every 3 years because of their problems)

If we get a truck again Ill probably go American, but anything else its honda or toyota.

My first teardrop weighed 880 lbs, was 10' x 54", fit in the wind shadow of my chevy Astro van and cost me nothing to pull (15 mpg towing or not).

My new teardrop is 5' x 10' and weighs 1380 pounds. I pull it with a 2011 Subaru Outback 2.5i. Without the trailer I get 25 mpg. With the trailer I get 20 mpg. I figure it costs me 1 gallon of gas to pull the teardrop 100 miles.
