It’s always weird how that works. My wife when I got her her 2.0 ecoboost edge. She drove it the first time and said. “It’s not fast like your truck” well I have over 500whp. I asked do you want it tuned? She said yes. So she got 93 and e30. The e30 was supposed to be for me. But she drove it one time on 93 after the first e30 tank and said nope put it back. She had blended her own e30 for over 200k miles now. She gets terrible fuel mileage.I hear ya! My wife has a heavy right foot too.
Driving vehicle is the same as playing a violin, drums, checking blood sugar, put smile on wife, etc, etc. Some people pay attention, most do not on most things. Some can "feel" the difference in "playing" their vehicle with a passenger or two than without them maybe while adjusting for windage differences. If driving 75mph with a crosswind they remember the position of their steering wheel with 35 mph crosswind. I don't like to drive with a tach because I am compelled to check go pedal position with rpm at certain speeds, (is there a headwind?).
I like the fact that people seem to be able to argue with respect on this forum. I'm taking a bit different approach here. Other than just my opinion, which is that it matters if it matters to you, but there IS a difference between 87 and 91 octane (Ford even said so). Take a look at the three sources below. They come from radically different sources...but still agree.
The Cliffs Notes are that if your vehicle can take advantage of more timing at a higher octane than it will gain power and economy from that. Whether it's worth it to you, as the driver is up to you.

I see a number of posts that are suggestive of this, but haven't seen a direct statement.
The gas engine in the Ford Maverick Hybrid is not Direct Injection. It is sequential multiport fuel injection (SMFI). Atomized fuel flows past the intake valves. Carbon build up isn't normally a problem when the gas/air mixture flows past the intake valves.

I believe you'll notice right away and it will only get better as the detergents in high test clean up any carbon from running 87. The slower burn of high test will also lead to less internal stresses.
In our 2023 Hybrid Lariat I run exclusively Ethanol Free "Clear gas". In Utah ethanol free gas is 91 octane. We consistently get 37 to 42 mpg on the freeway (80 mph speed limit in Utah) and 56-65 mpg hybrid local trips. Some local hybrid trips are incredibly fuel efficient!
Best way to illustrate 87 vs. 92 is running up a long steep hill. Try that and you'll understand why some say 87 is junk. The other way is get a test lab and run 2 identical engines under identical stress for 10K miles, disassemble and measure wear. First way is cheaper.
Well I hope you use crap oil or at least are in a salty area because you'll be driving that Maverick when the rest of us are beaming to our destination.In our 2023 Hybrid Lariat I run exclusively Ethanol Free "Clear gas".

On my 22EB, I ran top tier 87 most of the time and the 2.0 had plenty of spunk. No knocking, no issues under daily driving suburban and freeway.
I ran 91 a few times [that is the max in SoCal at most stations] and there was hardly any difference except in my wallet - 91 costs 40 cents more per gallon.
You can do your own test. You might settle for 87 one fill and then 91 or whatever, the next.
Unrelated to this post - in my 2024 hybrid, the engine sounds smoother and the exhaust noise has less "growl" when I use 91. But my mpg isn't any different so it doesn't justify the cost difference.

If you see a decrease in fuel economy when switching between octanes then something else is going on. There is no more energy in higher octane fuel than lower octane. If better fuel economy were on tap with premium then the manufacturer would require it use to meet federal fuel economy standards.

Instant indications from the computer are meaningless. The only way to truly test is over several tankfuls to average out all the variables.
Well I have owned a 52 year old classic muscle car for 32 years,and also have two 15 year old dodges. Have run 87 in them.no problems. You'd think there would be a problem in over 32 years!
