Ecoboost freeway observations

I drove the TT and family south of Portland on I5 for a few hours. It's a relatively flat stretch of freeway. 55-60 mph, 11.5 mpg, 1500 rpm and very quiet. Usually I drive over mountain passes so this was the first long flat stretch for me so thought I would share the numbers.

You must have been running in 6th. I ran mine 3500 miles over the past three weeks, mostly at 90kph (about 50mph) in 5th in tow/haul. We averaged right around 13-14mpg (Canadian gallon). Truck seemed to be lugging in 6th and noticed no difference in mileage to run in 5th. As I got down south near Saskatoon and Regina, I ran at 100kph (62mph), the mpg dropped to 10-11.

Just for comparison, last summer, we pulled that trailer to Whitehorse with our old 1997 Suburban, gas 350, got around 9-10, engine running around 24-2500. The old girl used about 3/4 of a liter of oil every day. It doesn't use any when not pulling a trailer.

Our truck pulled the trailer like you say, very quiet. Ours is a 6.5' box, Supercrew 4x4 XTR.

Because the truck shows everything in US gallons, I add about 20% to what the instrument shows. I have verified the mileage by actual fill, drive and fill, then calculate the true mpg. It is actually pretty close if I add 20% to what it shows on the dash.

I started a firestorm of insults and Ecoboost bashing on another forum when I posted what mileage i got on a trip with no trailer. Got called out as a liar, etc. We do live in interesting times!

The ecoboost has one of the most zealous following of purists I can ever recall. I suspect I read that thread. Never heard that kind of bickering when it was just the trusty old 5.4 and 4.6 mod motors.

As far as the manufacturers mileage ratings are concerned, my belief is that they (car companies) all overstate their numbers as far as they can without being sued. With that being said, I really never expected to achieve the EPA mileage ratings on the sticker. With the EB people are either thrilled with their mileage or terribly disappointed. Power comes with a price and I bought my EB for the power and nothing else. In the torque, HP and 0-60 times I have been very satisfied. The thing tows like an ox with a cattle prod jammed where the sun don't shine.

All I hear is great things about the EB, but I HATED the one I test drove - felt underpowered unless I put my foot in it, and then it felt overpowered. What am I missing?

I always snicker when I read these posts. Reminds me of the mid/late 1960's. My car is faster than your car... no it is not. Well back then it was settled in a 1/4mile (.155342798km?). I was always a GM guy, with no other engine but BIG blocks (427, 425,455CID). Here is an interesting note, my 1965, Oldsmobile 442 off the show room floor turned 13.65 in the 1/4mile, while a ecoboost off the show room floor beat that time. Granted, the 65 melted half the tires before getting any where, but a V6 with twin turbos... not bad! (After getting tires/engine mods the 65 ran constantly in the low 12's)

So, after researching my TV options (GM, Toyota, RAM....V8's, 150's 250's...) for a few months, I decided on the Ford ecoboost. Since less than 10% of my mileage was going to be towing, a diesel engine was eliminated.

Am I happy, yes!!! But to me what ever you decide on as a TV, is probably best for your needs. Will I buy another ecoboost...? Don't know, that will be based on current technology at that time.

Just my thoughts
Don

The F150 has the adaptive transmission PCM control thingy that constantly learns and adjusts to your driving style. The one you test drove was learning how to run from a clean slate..just learning its ABC's and how to count, if you will. The more you drive it the more it learns and adapts to your driving style.

Two identical trucks, one driven by a high school boy who got it from mom and dad for his 16th birthday and the other driven by a 70 year old retiree back and forth to Golden Agers Club meetings will perform very differently. If the two people traded vehicles for a month they would adapt to their respective drivers habits and perform accordingly.

I had my EB's PCM re-flashed when it was a year old and boy did it act different until I whipped it back into submission.

I have been driving V8 pickup trucks since I learned to drive, so it was a huge leap for me to go to the ecoboost. I've been pleased with it so far, but I didn't buy it for the mpg. I think that people who buy it thinking they're going save big at the pump are setting themselves up for disappointment. Also, the early ecoboosts had their share of issues that gave them a black eye from the start. Personally, I love how quiet the engine is and I love the whistle of the turbo. I have never owned a truck that was more comfortable than my 2013 crew cab, or that was as fun and effortless to drive. This truck drives like a sports car, but rides like a Cadillac!

Great explanation, thanks!
