How’s your gas mileage?

[antzman]

I just cracked 450 mikes on my Mustang GT yesterday. It’s been a combo of local driving with a bit of highway mileage. Yesterday I made a roughly 160 mile round trip drive that was primarily two lane highways. When I got home I looked at my average gas mileage and I was sitting at 20.8. Frankly I’m really happy with that number.

If I'm not mistaken, I saw a caption on a @All Terrain NAtion video where they got 24 highway MPG driving their car from MI to TN.

That's right about what Ford advertises.

I should have put the caveat that I never get good gas mileage this early in an engines life. Typically it takes me 1000-2000 miles before the engine settles in. That’s probably my biggest surprise. I replaced a 2020 Ford Explorer ST with my mustang and so far I’m getting right around the same gas mileage that I did with the Explorer with a much bigger engine. I’ll take that any day

The one video I did watch, as they were leaving Michigan, they were only going 65-70 MPH.

So that could have been part of the reason they got relatively good mileage as well.

I'm a speed demon (having learned how to drive in Detroit and now driving in Dallas, it comes naturally at this point), so can't say I will be taking it nearly as slow on my cross-country drive.

I’m curious to know what was the octane rating of your fuel? I know this was discussed in June. Highest in Canada is 94 at Sunoco and Petro Canada.

We did Average 24.2 from MI to Middle TN running 75-80 the whole way

I’m not sure what the dealership put into it at delivery, but I’ve used 89 octane the two fill ups that I’ve had to do so far

Personally I would bump it up it up to at least 91 or 93. Manual says 87 is ok. It is a high performance engine and over time will be detrimental to your engine. This was discussed thoroughly in June and consensus was the higher the better. Try a tank or 2 you will feel the difference.

Thanks for that, I’m waiting for my GT to come in, and sold my Explorer ST. Was happy with the mileage on the ST, so should be good with the GT

I just rolled my 24’ GT to 657 miles tonight. I’m averaging 17.6mpg, I’m doing a lot of stop and go driving as well as I’m not being super gentle on the car throttle wise. Not saying I’m mashing it everywhere but if the roads are curvy I definitely get speed going and play like it’s meant to play. Figured ford said run it how it should be ran, no break in needed so I’m holding them to the test lol.

I find these numbers a bit disturbing. My 96 GT gets around 22 miles per gallon in town and the run between Los Angles and Phoenix I was able to get an even 30 miles per gallon. The RPMs for a given speed will pretty well match up with my new Dark Horse.
Now I am an easy driver. I set the cruse control at the speed limit and don't touch the brakes or gas unless traffic forces me to. I would have hoped in that in 27 years Ford might have improved the milage at least a little. I will find out in a few weeks when my car shows up.

well the gas mileage didn't go up much but the horsepower nearly doubled lol

everything past the first sentence is wrong

No, the new engine is almost 2.5 times more powerful. The original 4.6 GT engine output just a little over 200 horsepower. It was a lot and earned you higher insurance rates but even economy cars generate that much or more horsepower today.

The only difference you will feel is the placebo effect that's kicking in.

When giving you 10 Mustangs to drive and after the drive you can't tell me which one is 87 and which one is 93.
