Anybody run the maverick on strictly premium fuel?

92 almost exclusively. The power difference is most noticeable in the summer heat with my heavy tires. I also drive over at least one mountain pass to go camping multiple weekends a month, so it's worth the money to me.

For an EB (or any FI engine), that would only apply under no-boost conditions. Under boost, cylinder pressure is very consistent, regardless of altitude.

Compressors have a finite speed and a finite ability. At a high-enough altitude it is conceivable that a turbo would not even be able to reach the wastegate pressure. I’m not saying the EcoBoost is designed this way, but just that of course all turbo engines are not going to deliver 100% power at all altitudes.

The Ford spec's for peak HP/TQ on the EB are based on 91 octane fuel. If you don't need/want maximum performance (towing, hauling heavy, peak acceleration, etc..), then you don't need to buy 91/93 fuel. There is no danger to your engine, you will just be down on peak power 10-15%. If, on the other hand, you need/want maximum performance from your engine, then 91/93 fuel is required. .

I don't know why this concept is so difficult for so many....

X2 Couldn't have said it better Myself!!

If you read the Owners Manual, under Fuel, it states that the EcoBoost REQUIRES at least 91 octane fuel to prevent engine damage, and that 91 octane non-ethanol fuel is recommended.

B.S. It says nothing of the sort.

I run my 22 non hybrid on 87 reg fuel. Hearing people get more horsepower and better for engine to run on high test. Any opinions?

My opinion- Documented truthful and accurate by small town Karen's International....

I get 34 highway, 46 city.... A tank lasts me a month or more.
within 5 miles of my house there are 8 gas stations. 7 of them are in lock step..SAME PRICE
the one that is cheapest is the Grain Co-op.. They have 1975 vintage pumps and you have to walk into a dumpy farm store and give them your credit card, return to the truck, pump then return to the Co-op, sign the register slip and retrieve you card. They are only open 8-5 M-F 8-Noon Saturday and Closed Sunday.
Save 8-10 cents a gallon and my tank is what 14 gallons?? Oh YES, I almost forgot I have to pass 2 gas stations to go to the Co-op..

In my 76 years, this Maverick gets the best mileage of any vehicle I've owned. I've been poorer, gas has been more expensive and less available in years past. I've learned to economize before it was fashionable. My mother was a coal miners daughter..

College educated Karen #27 asked.. How do you know you're pumping 91 or 93 octane? As did the station owner slip a few bucks to the delivery guy to top off the 91 tank with 87?
Then she posed this question- If all blends of gas are delivered through the same hose, the blending takes place before it gets to that hose, therefore you are never going to get 100% premium. Right?

Here is the moral of the story...

If you wanted fantastic gas mileage you should of bought the hybrid.. In 2022, the hybrid was base, and you just had to pay more for the gas guzzler you did buy, didn't you?? Sounds like buyers remorse..
Whereas, I paid extra for my hybrid, and I'm glad I did...

Just found a station 5 miles from my house added ethanol free gas. But it is $1.50/ gallon more than 93 octane and $2.50 more than 87.

Let me guess, they bill it as "recreation fuel" specifically engineered for off road use....at least that is what the Sunoco station in my home town down by the marina claims....

The highest the pump offers from day one. Don't know if it makes any difference on mileage or engine longevity. Never used the low end stuff so can't comment on any difference. 23 XLT AWD

If you read the Owners Manual, under Fuel, it states that the EcoBoost REQUIRES at least 91 octane fuel to prevent engine damage, and that 91 octane non-ethanol fuel is recommended.

If you read the Owners Manual, under Fuel, you would realize it doesn't state anything like this.


Selecting the Correct Fuel

Your vehicle operates on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in high altitude areas, offer fuels posted as regular unleaded gasoline with an octane rating below 87. The use of these fuels could result in engine damage that will not be covered by the vehicle Warranty.
For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer. See Towing a Trailer.
Do not be concerned if the engine sometimes knocks lightly. However, if the engine knocks heavily while using fuel with the recommended octane rating, contact an authorized dealer to prevent any engine damage.

Of course, but we are not talking in the realm of extremes here...no one is driving their Maverick at the top of Everst.

The biggest effect of (reasonable) altitude on FI is spool time, or lag. Peak boost will take longer to build, but the peak cylinder pressures remain constant, thus the need, still, for higher octane gas, even at higher altitudes, if maximum performance is desired.

I've had my XLT Tremor for 2 1/2 years and always use non ethanol 91 octane. I'd probably try 87 octane if it was non ethanol which is not available locally but mine can sit for a couple weeks and I have a hang up on using ethanol gas. I have 8500 miles on it and it has gotten 28.5 MPG overall which is way above the EPA estimate and most tankfulls I get over 30 on mostly rural 2 lane roads.

Only premium, no ethanol for me.

Not as important as dropping a bottle of 12 ounce Techron into the tank every four tank fills.

When I had my 2022 2.0 EB I tried both 87 and 91. It seemed to be a little quieter and smoother running 91 but I did not see a difference in mpg. If I recall correctly, the 2022 owner's manual recommended 91 for the EB so if I were to tow or do more than comute, I would follow the recommendation for 91.

No such thing as ethanol free gas here in MA. I run my 2024 EB on 87 (buy my gas at BJ'S most of the time) as I did with my 2015 Edge EB and my 2020 Escape EB, unless I am towing, then I up grade. I tow to northern ME often in the winter and their ethanol free is available as most stations as premium (91 or 93) as they sell a lot of gas to the snowmobile market up there. My snowmobile requires premium, but then I often add ethanol to reduce the possibility of water in the fuel freezing, especially in very rural locations where they often have tanks that sit above ground.
