Hey, the title pretty much says it. Just curious if anyone on the boards has had any experience with the new 3.7 in an F150? 300 HP and 17/23 mpgs (4X2) is pretty impressive in my book. Hoping to get another year or two out of my tired 4.2 and pick one of these up used if it's as good as it seems. Would appreciate the feedback from anyone who has driven or owns one of these.

Thanks!

I drove one for a couple thousand miles, but did not tow with it. I would imagine it would be just fine for towing a 3-4k lb trailer on mostly flat ground. But even without a trailer, it downshifted a lot in the hills of Virginia. Overall, Florida to Virginia and back, it got 21.5 mpg even with all the miles at 70-80 mph. Had a small load in the back up and a little bigger on the way back. It does have pretty impressive acceleration. The 1-2 shift occurs at about 6700 at WOT.

With that said, if I am buying a new F150 that will be used quite a bit for towing, it will be either a 5.0 or EcoBoost.

My buddy has one and I have the older(2010) 3v4.6. Its pretty close to mine with power. We both have mustangs and pulled out of a toll both towing them to the track. He was door to door with my truck pulling it to 60. The fuel mileage on the other hand is almost identical on the hwy with loads both of our obc said 15ish on the hwy when we got to the track and back.(about 30 miles one way).
I have the nls 3.31 rear end and he has nls 3.73 gear so it helps him out a little.

My Brother just got a 4x4 fx4 with the longer 6.5' box and ecoboost. I think he has the "TowMax" package too...different gears, mirrors and whatever else.

Pulls his racecar with a long tounge and storage box/tire rack on the front of the trailer every weekend a couple hundred miles a weekend.

He also just hauled a 33' bumper pull camper for about 5 hours last weekend.

I know he LOVES the power and comfort of the truck. The mpg's are about 17 if I remember correctly when pulling, and 22 unloaded.

That's pretty good mileage going at those speeds. The best I get out of my 4.2 doing all highway from Vegas to California is about 17-18 going about 80 the whole way, some good hilly stretches on that drive too. Next time I might slow it down to see if I can get 20 :) Wonder how it does with mostly city driving as that's mainly what I do. I get about 14-15 in the city unloaded right now, around 12 pulling a #2500 trailer.

I read a good post a while back on here, the "V6 work truck shootout":

It's a pretty slanted review as they're comparing Ford's new V6 and trans combo to Dodge & GMs yet to be updated ones. They did mention that Ford's 3.7 got around 20 in the city, but dropped a lot towing just a few thousand pounds, down to 14-15 so that sounds about right. Thanks for the response!

I get about 14-15 in the city unloaded right now, around 12 pulling a #2500 trailer.

Only about half the miles were at those speeds. I calculated the fuel used for the entire trip and that's what it got. Now watching the trucks mpg screen, it seemed to be in the 19.5-20 mpg when on the interstate. Rural highways brought the number up.

I've made this same trip three times in trucks, and once in a Trailblazer. The SUV was right at 20mpg. The 4x4 F150 was a 2006 with the heavy payload package. It had the 5.4 and 4.10 gears. It was right at 16.5 mpg. And the other was a Chevy 4x4 with the 4.8 V8. It got a little over 18 mpg.

So this truck was quite a bit better than any of the others. It was a crew cab 2wd with 3.73's. When I got it in it and drove off the lot, I wasn't sure that it wasn't a V8. The little engine runs pretty good.

I would go with the idea of them not being updated except that GM has not updated their V6 in what? 2 decades? They still haven't set up any real updates... even their V8s are getting long in the tooth and falling behind the times... ;)

I just bought my 11' 3.7... Great truck!! But i gotta take it back to get the transfer case checked out.. I have a hard time keeping the 4low from popin out of gear.. Great truck muuuch better pick up power than my old 5.4.. Cant even feel the trailer or the boat.. Big plus too on the large fuel tank.. Takes $110 to fill up from empty but lasts a good 600miles.. Good truck!!

Hey Evergreen, glad to hear it! Out of curiosity, which 5.4 are you comparing it to? I'm guessing you had the older gen 2 valve? And approx how much weight are you pulling with the new truck? The trailer and boat you mentioned.

Thanks!

Thing is I have a 01 gmc yukon xl with a 5.3, 3.42 rear, 4wd, and I get 20.7 mpg pulling a popup camper doing 75 upstate NY. For .8 mpg more I'll pass on the 3.7 6 cyl and stay with the 5.3 8 cyl and 8000 lb tow rating.

I have a hard time believing that you're getting that kind of mileage towing with that thing but if you say so...

my boat is by far the heaviest trailer ive pulled.. its a 21' Robalo with a 175 evinrude, hauls it very nice and pulls out of the water with ease.. the 5.4 i traded for this one was an 05' and all the tritons ive ever driven have been hogs they dont have very much pickup power (0-60).. im telling you man the new 3.7 is the real deal :weightlifter: .. hauling the boat yesterday i was getting 15.8mpg

Hey Evergreen, I was asking about the base V6 3.7 in this thread, not the 3.5 Ecoboost, but glad that you're happy with the EB.

It has nothing to do with this thread, and he must be pushing the wrong buttons on his calculator.

My dad has a 2010 GMC 1500 Ext Cab Short Bed 4x4 with 3.42 rear, 5.3L. He and I took a trip to Arkansas 400 mile round trip hunting a few months after he bought it. It got 16 mpg empty running 70 mph the entire trip.

My 4.6L F150 SC 2010 with 3.55 rear gets about the same as yours.

Uphill both ways too!

You have to drive with a light foot. No drag race starts. Soon as you see a red light pull your foot off the gas. Heading into a turn back off the gas so enough speed scrubs off so you don't use the brakes. Maintain a steady speed and I mean steady. On the steepest hills you trade off a few seconds loss of speed to keep the engine in overdrive. If the hill is that steep to prevent transmission hunting for the right gear down shift out of OD. Then hold it at 65 mph. As approach the top of the grade past point of transmission hunting shift back into OD and let the speed slowly pick up. Don't let the down hill grade take you faster then your desired speed, back off throttle to not waste gas.

In other words learn how to drive.

In other words learn how to buy a truck. Don't buy 4.11 rears, your not pulling the Queen Mary. Don't fall into the trap of buying too much engine and wasting to much gas.

At any rate you're just trolling man. I was asking people about their experience with the new Ford engine, not your Yukon. Not interested in a flame war here but come on.

Not saying GMs are better then Fords. Never intended to start a flame war.

Life experiences have shown 1960's v8 283's in full sized cars and pick ups not only gave better performance but gave better mpg smoother running and longer running then straight 6 250's.

History repeated itself back in the 1980's when GM was putting 3.8 and 4.3 v6's in full sized cars and again the option 5.0 v8's gave better performance
but gave better mpg smoother running longer running then the v6's.

The same old story not enough engine is just as bad as too much engine. Also the same with going for a higher rear end ratio then needed.

Now being you don't want to share my life's experiences. I no longer will do so.

I had a 2011 3.7L 4x2 reg cab, long bed, only option was limited slip rear.
It got decent mpg when unloaded, but I usually had 1,000lbs in the bed, then it got much worse mpg. I have a 6.5turbo diesel in a 1ton chevy, it uses less fuel on average than the 3.7L did (because its usually is hauling stuff). If you are going to get an f150, I recommend the V8 if you tow or usually haul weight, you will probably get better mpg with the V8 vs v6 when loaded.

I guess if your a "Grass Guy" a gasser v-6 may suffice but if you need to haul mulch, plants, and other stuff your going to be screwed. Real work trucks have no spark plugs. Why buy a home owner quality truck when you can buy a commercial quality Diesel that will last 2-3 times longer?

You couldn't give me a diesel pickup made after about 2008. I don't see those trucks lasting nearly as long as the older bulletproof 7.3 Fords and 5.9 Cummins. With all the emission garbage these things will be a nightmare to keep running right over the long term unless you tear all the smog stuff off. My 6.0 Chevy does not have the pulling power or fuel mileage of a diesel, but it pulls any load I need it to just fine and is stone reliable. Just change the oil and put gas in it. It should last 150K miles or more, and when the time comes I can rebuild the whole motor for what it costs to replace a set of fuel injectors in a newer diesel.

My 09' with a 6.7 is minus the DPF, EGR, and Nox converter. But there are also a lot of hot shotters with the emissions intact running around with 200,000 - 300,000 plus miles who never had any major issues. The first 2007.5' trucks had some bugs to work out but by 08' & 09' things were in pretty good shape. The 6.0 in the Fords and the early Duramax 6.6 had injector issues but that was about it. The Bosch injectors in the Cummins last just about forever.
