EcoBoost Mileage Better with Premium?

i am laughing till i cry. its 4.37 a gallon here and thats the cheep no name market (rotten Robbie's) and thats the cheep low grade stuff. if thay (the gas co.) post record profits again i just dont know how we should go about flogging them. i work in a oil based industry and there is just no call for it to be this high in cost.

There should not be much of a difference in economy from brand to brand, as all brands are supplied by the same suppliers/refineries (mainly corpus christi/houston for san antonio area)...The difference comes with the detergents additives that shouldnt have any effect on the performance of the gasoline itself.
Years ago the differences in brands were great, but due to stringent government standards and open market practices, really all gas is good and pretty much the same... That said, I'd look more at the station itself. My geologist buddy of mine does alot of work with the underground storage tanks at pump stations, and he says that many tanks are poorly designed, installed, and maintained. Bad tanks can produce excess condensation (water), deposits, and outside contamination, thus, hindering the properties of the gas.
Just my 2 cents

The same occured in my '05 Nissan Titan. I would only use Conoco when I lived in Abilene, TX. I ran Conoco in my '92 Ford Ranger, '94 Chevy C1500, '95 Ford F150 (4.9L) and '93 GMC 1500. I always try several brands of gas to find the one that gives the best mileage. I always received 1-1.5 mpg better using Conoco over Diamond Shamrock or Citgo. This was in the 90's when gas was 100%, no Ethanol added.
I always recommend friends and family try Conoco, Shell or Chevron when they mention receiving poor fuel mileage. They are usually running Sam's, Walmart, Valero or Citgo gas.
My youngest son bought a new '11 3.7L Mustang. He receives 2-2.3 mpg better fuel economy when running Conoco vs. Citgo. He lives in Snyder.
One Refinery may produce numerous brands of gas. The additive package is the key factor.
Run Valero if it work's for you. It doesn't work for me and it is usually cheaper than Shell in my area.
Enjoy your new truck.

Oh I am probably like the rest of people here and talk politics enough as it is, but I will be so royally pissed if those companies post more record profits again while we are stuck in a depression. Yeah and while I was stationed in southern CA a few years ago I saw real high prices, I wanted to just stay on deployment and not come back till gas and everything was back to normal but that couldn't happen, thanks IED's! (Sarcasm totally implied)
Anyways, while I am waiting for probably another month before I order my ecoboost I decided to try an ol trick on my current lifted 03 screw to get better mileage. I started driving 55mph on the highways again. Granted its like the 1970's again but with my setup and 33's I get sick of getting 12mpg. My wife has an 03 screw fx4 and she gets about 14 mph in hers driving normal so mine seems to be the hog. Has anyone tried driving 55mph in an ecoboost and see what the difference is? I'd like to know that along with the premium fuel improvements.

If I fill up and drive immediately home from work, I can get the avg. comp up to 23.1 and keep it there for about 17 miles at 55-57 mph. I'm at a half a tank and the avg. comp reads 20.1. It has fluctuated from 20.1 to 20.3 mpg for the last 5 days.

...
Regular at the Valero station was $3.70, premium was $4.00. That means that it would cost $96.20 to fill up on regular and $104.00 on premium from dead empty. That is a difference of $7.80 per tank. ...
$7.80/$3.70= 2.11...
2.11 gallans of regular of unleaded (x) 15mpg= 31.62 miles
31.62 miles/26 gallon tank =1.22 mpg improvement needed from premium fuel to breakeven on additional cost per gallon.

By your numbers:
Premium fuel is 8.1% more than regular fuel. ((4.00-3.70)/3.70 = .081 or 8.1%)
If fuel mileage is more than 8.1% better with premium, you are ahead. (15mpg x 8.1% = 1.2 mpg)
If less than 8.1% better, behind.
But will the mileage be better? It will be interesting to see. My guess, maybe if run hard or on a hot day, but I'd be pretty surprised to see an 8%+ increase in fuel economy.

Your calculations are way more complicated than it needs to be...
By your numbers:
Premium fuel is 8.1% more than regular fuel. ((4.00-3.70)/3.70 = .081 or 8.1%)
If fuel mileage is more than 8.1% better with premium, you are ahead. (15mpg x 8.1% = 1.2 mpg)
If less than 8.1% better, behind.

Higher Octane better power or mileage = MYTH
Higher Octane fuel does NOT improve HP or mileage.
What higher octane fuel does is burn slower to prevent denotation. That's it.
If your car/truck/whatever can run normal timing on 87 Octane... you will gain nothing at all from higher octane fuel except for paying higher prices for it.
Ecoboost will gain Zero from higher octane.

I don't know if Ford has released these numbers for the F150, but I think the SHO makes 10-15 more HP and torque on 93 vs. 87.

For most vehicles, that is true. For the EB (and many newer Ford engines), that is false. If an engine is tuned to check for the octane level and adjust timing due to the different octane level, it is possible to get more HP and better MPG if running higher octane gasoline.

for testing purposes, OP need to keep it at the same station (preferably the same pump) and run 2-3 tanks of 87 and 2-3 tanks of 93 to get more accurate results.

Get your whole rig recalibrated. Your truck's computer is set up for standard dia tires.. Plus the additional tire's contact patch equates to friction and those 4.10 gears ain't helping. You are getting 6.2 Raptor mileage
