We are considering one of these trucks it would normally carry about 1600 pounds in the bed. Does anyone know what they get for mileage when it's loaded down in the bed, not a trailer?
Thanks

 

I'd venture to say you'll do better as far as MPG with the 5.0. The 3.5 EB will be in boost a lot more with that much weight. I haul up to about 1k lbs in the bed at least once a month. My 3.5 will drop about 3 MPG when I do that. I live in a hilly area though.

So, if performance isn't an issue, get the 5.0. That's coming from a 3.5 EB owner.

 

All depends on your right foot. If you stay out of both motors they should be close, if you get into them the 5.0 will be better.

 

I was probably unclear. I was considering buying whichever one I could find for a good value, I was just curious what each or either did when loaded down. I'm used to diesels, which don't honestly care what's in the truck. Bed

 

Weight in the bed has little effect on mileage for steady highway driving for any motor.

I'm a huge fan of the ecoboost for its effortless power, much like a diesel. However mileage while under load is significantly worse than a diesel. Best way to think of that engine is that it can be Eco OR Boost.

It takes fuel to make all that power.

 

+1 to what seventyseven says. Even when I tow a lot, it is still 5-10% of my total driving. When the EcoBoost is not towing, I typically get 21-22 MPG; especially if I'm on the freeway. When I got fuel at a mountaintop gas station a couple weeks ago, the LoM was showing 45(+) MPG until I got down into town.

When I tow our TT, it is more like 14 MPG. None-the-less, there is zero drama pulling the TT. The power feels like a diesel under these conditions.

 

The 5.0 will have better mileage loaded up. The ecoboost has to use all of its power on tap to make it go down the road loaded, so much more has spent.

 

how exactly does the EB have to use 100% power to operate? If you're not flooring it then it's only using what is requested by the pedal.

 

If you guys had a monitor showing spark advance you would see the difference between a supercharged engine and a non supercharged one. Any time you lean at all on the Eco boost its advance goes to zero or close to it. The turbos make up for it but they cause heat and additional fuel. The 5.0 does react similar but not as mich. it's all in the computor controls to save the engine. Ford is pushing Eco's like crazy. I cannot find a 5.0 Lariat on any lot so ordered one here in So Cal, actually any model for that point. A 6.5' bed must be ordered, I guess guys don't use them as pickups much. Good luck.

 

The difference between the two will be in the weeds. It will take the same amount of energy (fuel) to move the load down the road. Both engines, as well at the 2.7EB, will haul it just fine.

 

This.


The bigger question, OP, that you might consider asking is how to option your truck. With 1600# in the bed, my F150 would already be overweight....without me even in it. My payload (driver, passengers, + all cargo) is 1564#.

Maybe you already have this worked out, if not, add it to the list of questions you need to research.

 

That’s a good point. I my CC short box had 1,500lbs remaining capacity as shipped from the factory. Maybe the HD version adds significantly more hauling capacity. I’ve gone well over the 1,500lbs with dirt for a short drive while the leave springs rested on the bump stops. Not fun, but no problems. Not sure I’d do it on a regular basis however with this truck. The current gen F-150s are know for liking to squat. I loose an inch loaded with just weekend camping gear. A SD might be a better option.

 

From what I understand the 5.0s and 3.5s can all hold about 2k in payload. That should be adequate.

 

Load capacity will range (approximately) from 1500-2500#.
Since you are still shopping, you can just look at the yellow sticker next to the driver's door striker. It's on all new trucks. Just try to pick a truck that meets your weight needs since it's a primary consideration.

Heck, it might make your decision easier because if you like a couple of them, just pick the one with the highest capacity.
