Gas Mileage Comparison

[GrabThatBlue]

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?

Yes I did.

Yes I did.

He wrote it so that people like you wouldn't say this. But even then there are people who still say it.

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

4600ish miles averaging 22.5, highest 26.
3/4 of my miles are highway at around 65mph.
i play a little daily, enough for a grin or two, sometimes three . Had her for about 10 weeks.

My average over 18 months is 13.4 L/100kms. Best was 8.6 ( a unicorn maybe, usually low 10's), worst was 19.

First, let me say that I didn't but my2024 GT Vert Premium for the gas mileage, But I am interested in hearing from the community on their experience with mileage. I started out stock and added a bunch of Steeda suspension parts which I love. Using mostly Normal mode and Sport mode, usually around town and on local freeways, I was averaging about 17.5 mpg always on 93 Sunoco Gas. Along about January of this year, that suddenly dropped to about 15.8 MPG average in all the same conditions. In May, I had a Whipple stage 2 installed along with Kooks long tube headers and Kooks high temp green cats. I did this knowing full well mileage would take a hit, but again, I didn't do any of this to get mileage. After Whipple and header install, I'm now averaging about 13.5 MPG. I don't track it and don't do any hard pulls. Just curious what others are seeing in the GT Premium configurations.

i’ve been getting around 17 to 20 miles per gallon around town if Eye Dr. sensible

i’ve been getting around 16 or 20 MPG if I drive sensible. Even with the AC on.
BUT,
Sometimes I have a Lead Foot.
My Mileage can be all over the place.
I only use TOP TIER Gasoline .
It costs more but worth it to me.
The most I ever have got is 27-28 MPG.
Colorado has some very Steep Hills to go down.
Mileage is very Subjective.
Probably 12-16 would be the best Average for me.

After one year, 13,700 miles. Mostly 80+ mph. Average 23.5 mpg. I run 91 octane E-0. highest mpg 29.3, lowest 12.6.

I just hit 1000 miles on my '25 DHP 10R80 with a stage 1 Whipple with extra cooling, dual fans, Bosch high flow coolant pump, Lethal double H pipe with high flow resonators, vapor catch can, and a Steeda Stop-the-Hop kit. I cruise my neighborhood in Sport mode and a little bit of full throttle from time to time. I'm right at 17.5 MPG. Love the way it pulls and corners. I didn't buy it to baby it, but I'm not surprised at my mileage.

First let me say I don't care about gas mileage, I didn't buy it for that. My 2018 mustang gt PP had 355 gears. Over 15k miles it averages 22.5 MPG. The 10 R very quickly up shifted in normal driving. My 24 Mustang has 3.15 and over 14k miles it has averaged 20 MPG. I attribute it to the 10R. This car even in slow acceleration holds gears until almost 3K RPM. This car feels 10 feet tall in normal driving in suburban driving. Much better then the 2018 GT pp. Wide open I can't tell the difference. Thank you Ford for recalibrating the 10R.

 

[glenng6]

As always. It depends....
My record is 3.9 mpg.

You know you don't have to race, all the time! Glenn

No difference noted between 95 and 98 here. That's your 91 and 93

I've been tracking all my fill-ups since the day I drove it off the lot and my average is 18.5 MPG and I drive it like someone else is paying for it. My highest is 34 MPG but that happens every year in March as I spent 2 weeks in Florida on a spring training trip for baseball.

 

[Ducatti20]

~19mpg in town and ~24mpg overall highway. It's been very consistent for me actually. I did a long road trip and got 26mpg on on tank one time but then I decided to get there faster lol.

 

[2026DHCARB]

I’m not achieving more than 11 mpg, I’m getting concerned about my carbon trap removal and K&N filters installation I did myself can have something to do. Car was new as were the filters.

I may have a leak.

While I don’t mind efficiency since my other car is a Tesla, I care if something is working improperly.
