hahahaha. More "IM RIGHT, YOURE WRONG!"
I think you can't read very well. My argument, if you would calm down and actually read my post that you flipped out about, is that there will be negligible difference in fuel economy, but significant difference in horsepower when the weather is hot. Read your own Ford Maverick owner's manual, it will tell you the exact same thing... I know, its a conspiracy!
I am not sure that you know what "scientific" or "significant" mean. You cherry picked data, made wild assumptions, and then accused me of not understanding the process.I think you can't read very well.

You have no means of completely draining your fuel system to compare 87 and 93 octane horsepower, no means of performing a back to back test, and have yourself admitted that you did no scientific testing such as running on a dyno or doing various performance tests like Car and Driver did.
Someone else cited the F-150, and I showed a 20hp difference even under cool ambient conditions with the source, along with various other performance tests. I cited the Mazda because its one of the few manufacturers that actually publishes what the horsepower is with different octanes on their website, and its a similar 250hp four banger turbo engine, and again cited the source.I am not sure that you know what "scientific" or "significant" mean.

According to APR, a VW jetta with the 1.4T engine makes 122-125hp at the wheel on 87 and 127hp on 91 http://www.goapr.com.mt/products/ecu_upgrade_14tsi_ea211.html. I believe it says on the sticker on the inside of my fuel door that the engine requires premium for full power (150hp), but makes 147 on 87.
The thread is titled "Do I need premium gas?" I'm not sure how anybody is moving the goalpost, we're all posting data, from different sources, on different cars, under different conditions. We can extrapolate the data as much as we want, the only thing that is clear is that the answer to the OP's question is no.
We basically have same approach except I use Lucas fuel treatment = keep everybody happy with 1 oz/5gal or so. Definitely use in every tank for small engines and run them regularly. I don't winterize my riding mower as I ride it every other day at least 1600 feet to my mail box. Starts quickly with Lucas cranks longer without. May not need as often with hybrid (maybe more so?) Since it will start much more often. Since it attempts to run at optimum generating efficiency most of the time with the charging of the drive battery only getting the excess current above that needed until the battery gets to some state of charge (70%?) At which time the engine turns off. As I understand the engine may start initially to preheat itself and catalytic converters so it can operate in optimum mode as well as to preheat battery to help it get ready to accept rapid charging from spouses braking habits. I did not order engine block heater as I live in Texas but wonder if it might help. Anyone know how the oiling works in the transaxle/transmission with the drive motor at such a high rpm (surely not submerged)?
Ah yes, the ole riding lawn mower to end of the lane to get the mail. 1600 feet is pretty close to what my parents do too to get the mail. hahahaha.
Those who deny reason can't be conquered by it.
Because my post is that there wouldn't be a big difference in fuel economy, but that there would be a significant horsepower delta particularly in the summer. The response that my post was nonsense was ultimately defended by him claiming that while he doesn't have an ability to measure horsepower in anyway, that he is able to calculate fuel usage.
It’s actually saying the evidence you presented does not in anyway verify your claims. You have anecdotal evidence of correlation, nothing more. There is no claim to you being wrong and I never even took a position to be right about.
