I don't doubt the EcoBoost produces more power with 93 but to what purpose? How many HP at 2000 rpm? Unless I'm drag racing Dodge Wildcats between stoplights on Hull Street Road that's the rpm the truck seems to cruise.
I find 93 makes no noticeable difference in normal driving or when towing my travel trailer. Including last month in the NC mountains with the camper behind.
As you know in Richmond 93 is always 60¢/gallon more than 87 regardless of the price of 87. $1.99 for 87, $2.69 for 93 a 30% increase in cost. When 87 was $3.00 93 was $3.60. Only 20% more cost but the same dollars. A typical 24 gallon fill is $14.40 extra for possible extra power I can't/don't use. I can get a 12-pack of beer for that.

We get in to this every time.
I never mentioned the cost...it isn’t a factor to me...sorry. I bought an 8 passenger boat. I expect fill-ups to not be cheap. I used to drive a diesel 250 when it got close to $5 a gallon. Everything below that is just a win.
As far as the power, I guess Car & Driver’s numbers must be wrong. Seems like a big difference across the board to me...but OK.
I feel the difference, so did the wife. The MPG increase slightly lessens the hit of the cost.
It is tuned now, so 93 or E85 depending on the tune.
Bottom line, if you want to see the stock advertised power on an EB powered Expedition, you need to run 93, or at-least 91...if that is all you have.
