As you would expect with a turbocharged engine's fat torque curve, RPM's were in the 3-4k range. Not as low as a diesel, but lower than the normally aspirated engines. Seems like it will be quite satisfactory.
Interesting. So you all are cool with 3000 -4000 RPM ?

What is the recommended oil change interval and what weight of oil do you run in the engine ? And sounds like you can run regular unleaded gasoline too?

Intriguing, Just asking.

Have a good one,

7500 miles is the recommended oil change interval. I have gone into Ford a couple of times to change it sooner and they say I would be wasting my money. They use a synthetic blend of oil.
The turbo's only kick in when they are needed and the 3-4000 rpm range is only used on very steep upgrades which do not go on forever. 90% of the time you are on flat to rolling hills terrain.

Ford F-150 Eco-Boost.

Now that fact about the turbos I find interesting. When driving untowed, with the windows down, there's a pitched hiss I've always assumed to be the turbos. A comforting, reassuring, "the engine is still mounted and operating" kind of hiss....

As soon as exhaust gas is generated, a turbo charger starts spooling up. Thus the need for immediate oil flow to the turbo bearings when the engine starts. Blipping the throttle before oil pressure comes up is a good way to ruin the bearings in the center section.

Also, one should consider installing an EGT (exhaust gas temperature gage) and get the temperature down to under 375 degrees before turning off the motor so the oil does not bake onto the turbine shaft and bearings (a process called coking). This idle time also allows the turbo to spool down to much lower rpm so when the engine stops and oil pressure drops to zero, the bearings do not get scored.

Since these are small turbo blades, they could be spinning over 200,000 rpm under full load. Both of our 6" turbos would spool up to 80,000 rpm on the Continental V12 M-60 tank engine.

In a new vehicle with good insulation, the turbine whine will not be very noticeable. Get a lot of miles and age and the noise will become apparent as the sound and heat insulation breaks down over time.

These turbos are also cooled by a water jacket that has been designed to allow coolant to circulate by convection after the engine is shut off. Therefore you should not have the same problem with coking that is possible with others. Having the water jacket should keep the turbos temp lower to start with and would remove excess heat very quickly. If you pull off the highway to buy gas, I would think the temp is already way down in the turbos.
I change my oil at about 12,000 km and use regular Ford oil, not synthetic.
Now have 140,000 km on the clock and no issues.

A little spool down time is far cheaper that the replacement cost of an out of warranty turbo charger and in this model's case, two turbo chargers.

We just returned from our trip from Los Angeles to Zion, North Rim Grand Canyon, Williams Arizona and back. I averaged with my 2012 ecoboost-max tow package-10.4 mpg. I drove 1,320 miles, used 126 gallons of fuel. I was averaging 11.5 for all of the trip until I left Williams for home yesterday. The head winds on I-40 from Kingman, AZ through Barstow, CA were unbelievable! If any of you have done that drive, you know that is a long tow through nothingness. We did encounter one big rig that was blown over. I think my mileage would have done better if conditions were more favorable. All in all, the ecoboost with tow package is my new favorite set up! The only 'problem' I had was driving too fast...uphill!

"nothingness" is right...it's not a place I would want to breakdown...what was your average speed? I usually tow at 65-68mph...occasionally at 70 when straight and "nothingness" is all there is...my 2012 is 4X4, but I still don't average quite as good as your reporting...

Check this link out:

Can the new 2015 Ford F-150 2.7-liter really tow?

Our Airstream-owning engineer puts EcoBoost to the test.

My truck is also a 4X4 157" wheelbase, and I set the cruise at 70, until I hit Calif. where the max trailer towing speed limit is 55- so I went around 62. I stayed around 1,800 rpm's.

Seems like Ford has a 2.7L Ecoboost F150 version now.

The 2015 "Build and "Price" tool is online. I managed to build a well equipped ecoboost 2015 Lariat SuperCab for $53,400.

Along with power heated/cooled driver passenger seats, leather, navigation, etc, the build included the max trailer tow package $795, technology package (back-up camera) $905, extended range fuel tank (33 gallons) $195, side steps $325, power trailer tow mirrors $165, adaptive cruise control system $1,250.

It also appears that 3.55 is the highest final drive, didn't see a 3.73 option. Looks like horsepower/torque on the 3.5 ecoboost is unchanged.

Review of 2015 F150 with 2.7 Liter ecoboost engine by Consumer Reports. Tom Mutchler test tows an Airstream. Pretty positive review.

I believe that at this time you can only build a F250 Super Duty also the 3.73 rear ends should be available. You can go to a dealer an order a 2015 and they have all the up to date info.
