If gas mileage is your biggest issue with the GT, then you should have purchased an Eco-Boost!

As a comparison...

My 24 Eco-Boost in town averages 19.5 to 20 MPG. On the highway at ≈70 MPH, it hovers around 35 to 36 MPG depending on terrain. This is with the FPT.
Have you even read his first sentence?

Does anyone see a difference when using 87 vs 89 vs 91 octane?

My car indicates to use 87 octane but I usually put 89 or 91

We can't get 93 here in the people's republic of California 🤬
