#141 of 740 2013 Escape SEL 2.0 AWD Gas Mileage
Sep 10, 2012 (7:33 am)
Just curious about what kind of MPG other owners are getting?
So my wife has had her Escape for 5 weeks. It has 1617 miles and I was ignoring the computer that says she is averaging 19.1 MPG becasue I know how much those numbers flucuate based on conditions. Her Trip B has not been reset since we have owned it and that says 17.9 average.
Well then I saw her CC statement. She has spent $312 on gas since we picked up the car. There is $272.54 in charges on her card and $40 cash on Monday. Her statement does not list how many gallons she has purchased or even the price per gallon just the total. But we buy gas almost always on base and it averages .20 cheaper than a typical gas station. Im guessing about $3.65 average per gallon. Then take into account it had a full tank when we got it, she has half a tank left now and I am estimating between 85-90 gallons.
Now I know 1617 miles in 5 weeks is a lot. Here is a quick breakdown of her usage.
390 miles round trip twice to visit her sister (99% highway driving)=780
454 miles to visit my parents, again over 90% highway driving. = 454
For work she drives 11 miles each way 8 of which are on the highway.
She only works 14 days a month and has driven her escape to work 11 times since she has owned it. 11x22=242
total of 1476 so that leaves 141 miles of her going shopping and local errands.
I am just thinking with over 90% highway driving she should be above 25 mpg average. Oh and also, she does have the Eco award for anticipation and acceleration on her dash if anyone thinks that matters.
I had posted this on a ford forum two weeks ago and have only received one reply so I figured to give this forum a shot.
So she has had her Escape now for almost 8 weeks and still getting horrible MPG. She now has 1920 miles and shows 19.2 on the trip A (reset after each fill up) and 20.8 on trip B (never reset). Again she still has the Eco Award.
As if the bad MPG wasnt annoying enough she told me last night after getting home from work that it stalled while she was at a red light and when she started it back up her Myford touch screen was blank. So I am starting to think we got a bad one. Anyway we are going to the dealership in a few minutes to see if they can get her touch screen back on and I will be mentioning the bad MPG also.
Any thoughts or suggestions are appreciated, Thanks

"...As a general rule....8:1 effective....cam intake closing event...would need 13.2:1...."
Why are you using an Atkinson engine specification to justify an Ecoboost engine not being detuned..?

What are you talking about? The example in the article was actually for a small-block Chevy. Standard Otto-Cycle.
Why are you claiming a naturally aspirated engine can compress less than 1ATM of air to its static compression ratio?
Do you think an engine is getting 12:1 Effective CR in total vacuum? (I.e outer space?)
What exactly is an engine compressing? AIR.
Less than atmo, your beloved Skyactiv is NOT getting 12:1 Effective CR and you know it. It is not possible
Boosted engines, on the other hand, frequently exceed their static CR, and have a range of effective CRs under boost, up to double their base CR (bone stock, in regular gas)
That is NOT specific to Atkinson engines. Don't tell me you have your patents screwed up in your head again?
This is true of ALL 4-strokes.
ANY boost calculator on any boosted engine shows that more air in the chamber = a higher ECR.
Effective CR / Static CR = air chamber pressure / 1ATM. Simple calc that shows that under vacuum, ECR less than SCR. Above vacuum, ECR greater than SCR.
So yeah, your 'detuned' argument falls flat on its face.

I can speak for the 3.5 Ecoboost in that it has to be broken in.
The first 6 months I got 17 highway mpg. Now it's more like 23 average highway trip (granted, I'm in the non-economical F-150).
Of it is stalling at lights as well, that needs to be looked at.
Sorry cant help more.

I have a 2.0L Titanium and my Fulley stats show I'm averaging 25.8 with 50/50 driving. The one thing I noticed is you have to be light on the accelerator from stops or mpg's suffer.

No, a DFI engine with a compression ratio lower than 10:1 is NOT efficient. SkyActive DFI engines are running a CR as high as 14:1. Yours would probably get much closer to 40 MPG were it not for the EcoBoost engines being so severely "detuned" in simple cruise mode, off-boost.
To summarize, NO.
Skyacyiv under 'cruising' will have a Dynamic Compression Ratio of only 7.9-8.9: :1 depending on throttle position.
Whereas Ecoboost will have a cruising ECR of 9.5-11:1 CR. On average, higher than Skyactiv.
ALL the literature out there supports this. I can link I you like, but maybe another thread would be better so the good people of the Ford Escape forum don't have to hear your ridiculous theories
#147 of 740 I must be LUCKY!

OR, only the people with problems post. I Purchased A white tricoat SEL 2.0 With touch, park assist, Navigation, sunroof, blis, (loaded) In July. I now have over 4,800 miles on it Average gas (my calculations) mpg is 28. I had 1 problem with the car stalling on a hard acceleration(not good) 1 trip to dealership who talked with ford while they were troubleshooting, never saw the problem again and that was in the first week of ownership. My Ford Touch works fine for me. It took a while of sitting in the car with the instruction manual and several errors on MY part to get it. Nobody, but maybe Bill Gates, is going to hit the ground running with a new operating system like this. If you own one or are test driving one, the best place to start is ask: "what can I say?" read the screen, find what you deem useful and go from there. If your trying to learn and drive at the same time, GOOD LUCK. My favorite so far is to tell her "I'm Hungry" she ask local or in town and away we go to dine, actually found some great restaurants that i did not know about. But probably the most important thing MyFord Touch has done for me was getting myself to an ER after an injury. I didn't know where the closest hospital was, (wasn't life threatening, just painful) but i declared an emergency, then hospital, and the car guided me to help. It wasn't a lifesaving event by any means, but I think I appreciate this new technology a little more.
To sum "I like my new Escape"

I have had mine since 24th of August just a few days past 2 weeks and display shows consistently now just over 27 mpg. Titanium 2.0 fwd.
Lot of local 15-20 mile trips with not much stop and go and 90 % Interstate and the rest suburban driving 40-45 mph. Using a calculator the mpg is a little over 2 mpg less. I have seen the drving style awards on MFT and not sure how they are calculated but have them on my display. I have seen almost 29 mpg on longer Interstate trips. I only have 700 miles on mine so seems like the EPA sticker is pretty accurate. They may be able to put your car on the diagnostic system and tweak a few things that relate to mpg. AWD will be slightly less mpg than fwd. I really like the vehicle more than anything I have owned and I hope your problems are resolved soon and to your satisfaction.
#150 of 740 Native vs effective Compression ratio.
Sep 10, 2012 (7:04 pm)
I have always espoused that effective compression ratio is equal to native/base compression ratio at WOT. Otherwise the effective CR is a function of throttle plate position.
The issue of atmospheric pressure, as even in the vacuum of space, was brung up.
So what is the effective compression ratio vs native compression at at sea level/WOT vs 1000ft altitude/WOT..??
It is my opinion that the effective compression ratio does not change as a function of atmospheric pressure. There may be less "air" to compress, but what air there is will be compressed at the sae ratio as at sea level.
