ecoboost mpgs

[aerostealth]

All mpg is contextual. With a Herndon Aerolid and a Cd of .34 my getting 30 mpg was just a milestone. I have done 29 mpg before. With the warmer weather I am seeing higher numbers with the lower air density. Relax guys I am getting ready for a round trip to Monahans TX from Las Cruces NM and I will have a report on the trip with bona fidas. Until then I am excited to see these high numbers without the boat tail. For those of you who think the eco boost is a joke try making a 6,000 lb anything get 30 mpgs at 55 mph then you will have a leg to stand on.

I have done 29 mpg before.

The log only says 18. Incidentally, that's no better than my 21 year old 5.0 4x4.

What do you tell everybody- 18 or 34?

Hey! I get 70 mpg with my Tempo!

Let's cut the hating. EcoBoost can potentially give some decent numbers, his are on the high end but plausible to me. Let's welcome someone who cares to watch their MPG, eh?

I just spent a month in a '14 F150 5.0. The fe gauge was in 1-6 bars. Damn near impossible to hold 6 bars for a trip segment no matter what speed, although they could be had for small distances, barely perceptible downhill grades, barely perceptible deceleration, and favorable winds.

These small insignificant snapshots of a little slice of perfect conditions mean what?

While I agree with the haters that it would be nice to see a fuel log; I also appreciate that you are paying attention and working toward a goal. It's nice to see that you can get mid-30s in a vehicle that large. Yes, it is just a snap shot but the more see that snapshot the closer the average comes to it. Keep up the good work, would love to see how much you are able to squeeze of that package.

It'll be interesting to see what the new 2.7 ecoboost gets. Thats a tiny engine for a full size pickup.

Also, Ram Ecodiesel.

A 3.5 liter ecoboost is only 213 cubic inches. I can routinely get 24 mpg at 65 mph and 27 mpg at 55 mph. Of course any city driving kills the averages. My latest composite average for the last tank in the warmer weather is 19.7 mpg. I thought the goal here at ecomodder was improved mpg's through aero not hating on Fords or anything else?

You're doing great. Keep up the good work. Aero is one of the multifaceted emphasis's of this site. People just like to see long term sustained results with documentation. There's nothing wrong with getting excited about the aero benefits you're seeing, but you would have more positive feedback with more information and more details about long term mileage gains. Thanks for posting

I have and I will. In fact I just posted a graph of my composite averages through the winter and they are not great. Cold weather and higher air densities are a mpg killer. Any of you guys tracking through the winter should know that? My upcoming trip in warm weather should tell a significant story. City driving in a mix kills mileage. The combined mpg sticker on the truck is 17 mpg. If I am now producing over 19 mpgs as a composite average that shows what the aero is doing. The high mpg returns on the highway are dragging the averages up. That is valuable information. A trip log of the last 5 months while interesting is not that indicative of the benefits of aero because of the air density problem. I will have some trip results on the 13th or 14th for you all. From now until October is when you should be trying to get good data.

Yep. My winter mileage suffered tremendously. Here's my graph from the garage. As you can see things went way south around November.
