EcoBoost?

[613GT500]

Another thing to consider when buying the 2.3l.
Final performance numbers will depend on the fuel you purchase, and timing may dial itself back with the use of regular.
Not uncommon with turbocharged, or higher compression engines.

Which is also the same case for the 3.5L EB.
Advertised HP and TQ are based on 91 octane or higher.

Same deal with the 3.5 EcoBoost. Ford's advertised horsepower rating is with the use of premium fuel. You can expect less power when running regular gas due to knock sensors dialing back ignition timing.

On another gasoline-rated topic, a new study shows benefits using "Top Tier" gasoline:

After a few regular octane fill ups I filled with premium last night. I instantly felt the acceleration get buttery smooth. I'm pretty sure it wasn't placebo either. For the extra $5, I think I'll continue filling premium for now. Either way, the car handles great with regular also.

There are many opinions on the premium vs regular gas debate. The Manuals for the 5th generation Explorer, regardless of engine, state that 87 octane is the recommended gasoline. The HP and Torque numbers advertised were achieved using 93 octane as mentioned in Ford's literature. 93 octane will improve performance but is not required. I noticed no difference between using 91 and 87 for my regular diving needs. Most gasolines sold have a certain amount of cleaning agents in them, at least in Canada they do. At the station I use (Petro Canada) the amount of cleaning agent increases with the jump in octane levels. I have no plans to go back to using anything other than 87 octane in my Ecoboost.

Keep in mind also, that the lower grade fuels contain up to 10% ethanol; which is another reason I fill up min of 91 octane.

Actually, all fuel, including 93 octane fuels around here are blended with 10% ethanol. Ethanol has nothing to do with lower grade fuels. In fact, ethanol can increase octane figures.

Non ethanol fuel for marine or two stroke use is available, but the highest octane level available is 91. It is also an extra dollar a gallon.

Yup, that's why I frequent only a few gas stations in my neck of the wooks, where 91 octance and higher has 0% ethanol...just a personal preference I guess

I believe all fuel, regardless of octane contains 10% ethanol here. There are a few exceptions. http://pure-gas.org/

That's correct and I only visit those that offer pure gas, in which the pumps are labelled accordingly. I see that you reside in Ottawa and can take advantage of 3 cents off per liter at Ultramar every Thursday.

10% Ethanol doesn't effect the performance of a four stroke engine.. Or so they say...and I believe that. But, I did have a friend of mine blow up his boat engine (GM 350), and his mechanic said it was from running hard and using gasoline with ethanol.
That was enough for me.

From his experience, I run ethanol free in the toys. Like you guys, it makes me feel better.
There is also a corrosive nature with ethanol when you store a vehicle without treating the gasoline. Remember to use ethanol stabilizer if you guys store your stuff over the winter.

I get 12 cents off per litre at Petro Can every time I fill up using the Petro Points fuel savings card (10 cents) and my Petro Canada MasterCard (2 cents). I currently have 1.7 million Petro points. That is the only gas I use (used to be Sunoco).
