It's amazing that most everybody else here is reporting 11-13 mpg at typical highway speeds, yet you are able to achieve 11.8 going 80-112 mph in the mountains, and he can get 12.5 at 90+. Perhaps your mountain highway was all downhill. Here in the soaring mountains of Lower Alabama, mine gets 12-13 mpg, unloaded, driving in the low 70's. Wind resistance is proportional to the velocity squared, and F250's and Excursions have roughly the aerodynamics and frontal area of a small shed. Excuse me if I'm skeptical.

 

Yep, I was mistaken. I have Bridgestone Revo 2s on my truck and I guess they have an R rating, so 106 mph. Makes me wonder which tires I though I saw that on, maybe it was some trailer tires.

 

i have it logged, at typical highway speeds i can get 13.5-14.1 MPG. real world numbers with my '02 3.73 4x4 Excursion with a SCT3 tune.



big red excursion Fuel-up Log | Fuelly

After looking over my logs from 2012, on the way up when i was running real fast was 11.3 MPG and on the way back also running hard but not as hard i got 11.7 MPG hand calculated, gallons divided by miles traveled. I run the same size as stock (around) tires so my odometer is correct.

think whatever you want, i know what i get as I've made the same trip in my previous Excursion also (same V10, 3.73s and 4x4 with same tune) and got 13.8 MPG when running closer to the speed limit (65-75 mph)

on other trips with lower speed limits running around 63mph i was able to obtain 14.1 MPG but driving that slow kills me.

 

Let me guess: you were transporting hungry, orphan children to their chemo treatments...?

 

Nope, hardly any traffic and i wanted to beat my best time getting up there. Thats all

 

If by typical highway speeds you mean 65-75, then mileage in the 13's is certainly possible, I usually run in the low 70's and can depend on 12-13 unloaded. And if you're running around 80, then I can believe your 11.3-11.7 numbers. If you spent any time at all at 112, it would absolutely kill your mileage, because you'd be lucky to get 5 mpg at that speed.

But, there is no way these things will get 12.5 mpg at 90 mph, which is what I was saying in the first place, and if you can only get 14.1 mpg by running at 63, then I would think you'd have to agree that 12.5 at 90 isn't credible.

 

<p><br /><br />Take it or leave it. I don't give a **** if you believe me or not. 12.5 is still terrible mileage. I only reported my ENTIRE trip total. thats 1400 miles freeway, approx 200 miles around So-cal. My 2001 was 8-10 all day long rolling 42's. My next questions are:<br />A. Why would somone lie about MPG on a V10??? not trying to sell you my truck, or get you to buy my gas for the year, so what gain?<br />&nbsp;</p>

 

Spent a whole mile at 112, then plenty of passes at 90-100. but you have to remember this is over 400 miles, so there was periods of 45-55 when going through construction zones..ect. it all came out in the wash it seems.

Considering my V10 is a 2V and 4 speed tranny, i believe a 3V and 5 speed could get 12ish at 90.

 

13.5 mpg at 80 mph with my 3v so I'd say 12 at 90 wouldn't be far off. The 95 mph cut out needs to go away on my truck, it's very rare that I go that fast but when it's needed its 95 and pulling hard then bam no more speed for you.

 

<p><br /><br />Thanks for your civil response.<br /><br />In your original post you said you got 12.5 at 90 mph, and I just said that this is extremely unlikely. You are now crawfishing and saying that the 12.5 was a trip average, and that's not the same thing as 12.5mpg at 90 mph.<br /><br />A. You'll have to answer that.<br />B. If you're going to get all offended when people point out misleading statements, just don't make them.</p>

 

I think he did say average.

He did answer it.

 

Exactly, same as i said i ran really hard on a road trip with speed up to..whatever speed and i averaged over the whole trip whatever milage. Pretty simple.

I assumed this was how it would also be read.

 

What reason do you have to lie AlaskanEx? good story for a hundred of strangers on the website? LOL. Some people are just so angry in life they can't possibly let other people enjoy it. Thanks for the help from the go with these troll idiots.


Vwags, thank you for pointing out the obvious for me while I'm to busy to defend myself from net trolls. I appreciate it.

I'm starting to hate the internet. I'm not a fisherman ( I fish like crazY) but I don't tell stories. I work in a very professional field where a tall tale would get you beat within an inch of your life. Matter of fact the only thing that would get you in more trouble is calling someone a liar. Exactly what YOU did. I provided information of a recent trip for people to review looking for info on the V10, you out and out call me a liar.
Furthermore; Im a fairly successful guy, with a beautiful wife and three kids. A great career that pays me WAY to much. So tell me again if I were going to lie why would it be to a group of strangers on the internet? And why would I lie about my gas mileage? what exactly is the point? I have receipts, and store locations of EVERYWHERE I bought gas. I can prove at any point in time that I did in fact average 12.5 (well, actually 12.47 EXACTLY). Can you prove I didn't?

Also, go read the front page of this thread. people are reporting 14-15 MPG. and even some easy drivers reporting 12 with a load. GO call all of them liars. My truck is the 5r110 and 90 MPH in final is only about 2800 RPM's The V10 loves to maintain RPM. On the flat freeway between here and Vegas and the three little climbs between them and California it didn't have to do a lot of accelerating, just stick it and stay.

 

Wait now you claim you work, are married and have kids? Now I call b.s.. Just kidding. Actually we had a 2003 Tahoe with a custom ecm tune that averaged 23 mpg for the 2500 trip we took to Oregon and did the same on the 3000 mile trip we took earlier, in a vehicle that was epa rated for 18 on the highway. Sometimes good things happen.

 

Alright enough of this hogwash

Seeing as this thread states "Real world MPG of your v10", here is my real world MPG tracked. Of course I'm probably lying with the numbers in my app too. Ha. Proof in my numbers, but mine will be worse with the dual rear wheels and it's constantly attached to a trailer.

Here lies the problem with this. This is MY real world mpg. Maybe your real world is all highway driving. If so my mpg has no bearing on what "average" is for someone else. Right?

Good day fellas. Lets all just be nice and not name call, no reason for that stuff.
