The only difference i noticed was it cost more to fill up.

On my hybrid, I noticed a 2 mpg increase when running 91 octane.

On my hybrid, I noticed a 2 mpg increase when running 91 octane.

Just curious……….
From 30 to 32?
Or from 48 to 50?

From 35 highway to just over 37

On my Eco, 2 mpg gain with
93 octane NON Ethanol but that does not offset the higher per gallon cost.

So now basically I’m driving my Ecoboost like it wants to be driven, In The Power Band just above grandpa style and I’m getting 27 mpg.
I’m good.

Just about ready to fill mine up for the first time. I think I'll be somewhere around 25+ mpg.

87 TOP TIER fuel only. Better additives for engine performance.

I haven’t used anything more than 87 Octane since I got this little beast - I may try Sunoco 94 Octane if I decide to take her to the drag strip one day

So far 3 tanks worth of gas on my Lariat ECO. All city miles. Onboard gauge says 24.7 mpg using regular. My first road trip is next week Boise to Reno 422 miles. Will I make it on a full tank is my goal.

The 2.0 ecoboost engine is mapped to 91 octane. So to achieve the full 250hp rating you need to use 91 octane.

Using 87 will result in approximately a 10% reduction in power from the stated 250hp.

For city driving, I get 2 mpg more with 91 octane. For highway driving, very little difference.
