Ecoboost automatic mpg

[Reaper]

If we're talking about making maximum power, I'd agree that, in general, this is the case (with the exception of the higher RPM statement). We're discussing gas mileage however, so that really doesn't have anything to do w/ the topic at hand. Also, to answer your question...tune and a small turbo. These are already being addressed by the aftermarket...however again this has nothing to do w/ MPGs.

You state that the comments have nothing to do with this MPG discussion multiple times, displacement is related based on Zack's inclusion, so how do you just ignore it? The turbo is part of the reason EB drivers are getting poor MPG, so again, how is that unrelated?

If he had some technical explanation for his opinions, I'd feel differently, but he doesn't provide anything of the sort. I'll agree that he posts a lot...but 'contributions' is stretching it, imo.

Do you hyper-analyze everyone's opinions, when they are just that, opinions? Maybe he just doesn't like the EB or dealing with a turbo, who cares?

(Sorry that I feed a Troll)

Someone asked him a question about his vette in which he replied so how is he a troll? Sure, maybe he would be better served in a vette forum now that he has "gone to the dark side" but he's not a troll...

I can't follow what your point is. You talk about displacement, then power and high rpm, then...well, I'm not sure. I'm more than willing to explain the thermodynamics, I just need to be able to understand what it is you don't understand. ..

The turbo 'could' be a reason for poor mileage, but there are other variables at work, such as driver input. It's not reasonable to make a conclusion w/o first identifying all of the variables.

If by 'hyper-analyze' you mean 'read', yes. I always thought that's what forums were for, but it seems some think they're a place to just 'talk' and not 'listen' and comprehend. Also, if he doesn't like the EB or give any technical reasoning/advice, why is he posting in this thread? Pretty sure I read in the rules that we're not allowed to talk poorly about these cars unless they were constructive criticisms...

Post 20. No one asked about his Vette.

I am sure everyone got it now that BRENT302 has a Corvette now. I am happy for you! How is it as a daily driver? No? Most of us who are using the Mustang as a daily driver is a V6 or EcoBoost more than enough. I could post now a picture if someone like where it shows 38 mpg on my EcoBoost because I drove only 55 mph/90 km because of the icy roads we had. Posting pictures doesn't show real day living. I am sure when Brent302 puts the pedal down the 34 mpg are gone in smoke too. Absolutely nobody needs a 6.x liter engine as a DD anyway. (Sorry that I feed a Troll)

I'm sorry that my opinion seems to have offended you. My Vette as a DD is excellent! Claiming you don't need a 6.2L as a daily well I could say you don't need a 2.3 or 3.7 according to your logic so a Fiesta with the 1.0L is more then enough for DD. [emoji106]

You're not feeding a troll at all. I do notice that there are many sensitive people here that don't like to hear that other vehicles do things better. Please don't go to a Cars and Coffee because you will be surrounded by other "Better" cars that people will be discussing.

Look - I don't know who you are, your background, your education, or even what you drive and that's fine. There's no need to patronize me as I don't need to explain myself to you either.

My point is that you seem to write off anyone who comes into the conversation with a different view, right or wrong. Maybe I wasn't clear enough with my response but maybe you should stop claiming that I don't understand when you don't make an effort to elaborate yourself (such as why my points have "nothing to do w/ MPGs").

The turbo 'could' be a reason for poor mileage, but there are other variables at work, such as driver input. It's not reasonable to make a conclusion w/o first identifying all of the variables.

Please reread my posts as I agree with you and basically say the same thing.

If by 'hyper-analyze' you mean 'read', yes. I always thought that's what forums were for, but it seems some think they're a place to just 'talk' and not 'listen' and comprehend.

Again - the whole patronizing thing you have going on. To clarify, you seem overly critical when it comes to others opinions. I also think you are taking the rules a little too literally but I understand where you are coming from.

Check post #27. For someone that sounds well-read and sure of himself, you should review the facts.

:focus:

To get my post back on track rather than continue to argue semantics, ZeeVee, Herr's advice below is sound.

I know when the F150 EBs first came out there were complaints of poorer than expected mileage. Two factors seem to have contributed...stay out of boost and also give it 5000 or so miles. Many people said their mileage improved drastically after that point. Not sure if a reason was ever determined, but the effects were seen. Give it some time before jumping to conclusions.

Give the EB some time/miles to break in and maybe it will work itself out. Otherwise, you could get it checked out anyway for piece of mind (hopefully not like Obie's experience).

You might also want to check the airbox for debris or lose fittings just in case. A while ago, my mom was having some MPG/power problems in her old Explorer. I took a look and it turned out to be a birds nest in the air intake chamber because she let it sit for too long :doh:.

Certainly we can agree w/ the cause and effect nature of the fact that if the unsolicited Post 20 hadn't of happened, Post 27 never exists...

Also, yes, I think opinions should be based on facts and should be able to be defended. That's how knowledge is attained, correct? Not all opinions should be treated w/ equal respect. Those that hold up to scrutiny sometimes even become 'fact'...but this is hardly the place for an epistemological debate...

but for the most part the more engine displacement, the easier it is for it to make power (especially at higher RPM's).

Think of it this way, all things being equal, it takes 'x' amount of energy to move a car from A to B. In essense, the same amt of fuel is consumed.

This is going to be grossly oversimplified, but hopefully the idea gets across.

Now, for the same car, let's say it takes 30 hp to sustain 55 mph. Assume the large engine makes this much power right off idle, say 1200 rpm, whereas the smaller engine makes it at 1700 rpm. So what we find is that over the distance from A to B the same amount of air, and therefore fuel, is displaced/consumed.

The smaller engine has to turn more rpm to displace the same volume of air and fuel as the larger engine to do the same amt of work, but ultimately, the same amt of work is being performed.

Again, greatly oversimplified.

When speaking about max hp, the same idea applies. Want 4.6L hp out of a 2.3, turbo it w/ another atmosphere of pressure. Want a 302 to make the same power as a 351, spin it another 1000 rpm. It's all about volume displaced.

Last point, in general it's usually easier for smaller engines to make more power per their displacement. Smaller = light. Reciprocating assemblies are easier to accelerate and valvetrain is much easier to control at high rpm.

Hope this helps.

i think just me reading this forum i might become a car wizard soon

Didn't Car & Driver do an article where they found the economy gauges where not always accurate? I don't know if anyone mentioned it but the fuel economy ratings are not real world results but a way to compare cars when shopping.

I don't think anybody has a problem with your 'Vette! They're fantastic cars. I couldn't get one because the plastic body would be absolutely destroyed in NYC -- and also because there are some limitations to it for hauling groceries or luggage for roadtrips and whatnot -- but it's an amazing car and I'm sure you're really happy with it!

Nobody goes by the economy gauges to mark out fuel economy -- you take the mileage since last fillup and do the math when you fill the tank.

A few people walk around here with pitch forks and need to get over it is all. Like I said some of these guys I feel very sorry for. If they showed up to a Car Meet they would not be welcomed back for the "I must be right" "ignorance is fun" attitudes but hey keyboard warriors am I right lol

All, enough with the personal commentary between individual members and all the off-topic discussion. Let's get back on track.

My wife's Edge gets 18city 28hwy. It's a V6 and weighs 4,000lbs.
Why are some of the EBs getting bad mpg? heavy foot?

Obie is your arm typically hanging out the window...causing drag?

I still haven't driven one yet but common sense tells me the Ecoboost is a lot of car for such a tiny motor to try and move w/o help (boost). My 2005 Scion tC with a 2.4L had a 5th gear so short that at 70mph you'd be more than halfway through the powerband. And THAT thing got 29 on the highway.
