I don't know how great they work, but i keep using them.
I own a 2021 Toyota Sienna Hybrid, which it is supposed to give me an impressive gas/mileage performance (mind the driving habits). One day, I noticed that when I filled my tank in the cheapest station in the area, and with regular 87 Octane gas, the gas mileage was extremely mediocre for a van that is supposed to shine on that aspect. I did some research and found out that better gasoline with higher octane will help improve this dramatically. So now I always use premium gas 93 or over, and one of these bottles between fills. The gas mileage is what it should be in my car, so the extra money I'm spending to fill up the tank, gives me extra mileage and it compensates, not to mention that supposedly it keeps the engine components cleaner.

Gas Is Expensive!
Gasoline is expensive and so are octane boosters! For the price point, this is a good value. This product treats 20 gallons with a octane increase of 2 points. I use this in a 5.7L Hemi with 282,000 miles on it. Give it some time. I sense it works well. Quick start ups,acceleration, smooth idle. Gas mileage increase, not so much.

helped my car's indigestion when premium wasn't available
I have a 91' that supposedly can use regular fuel. Was out in the boonies and really needed gas but didn't have what I preferred. I recall the manual didn't say I needed premium so I got what they had. Good thing I have some paranoia about stuff and had a bottle of this in the glove for emergencies. The next start the car ran rough and struggled to idle. Poured this in and cranked it. It took some throttle to get it sputtering but once the crap gas passed thru the line, the idle evened out. I figured booster ups the rating a couple numbers or maybe 3 (87 = 89 or 90) so it was close enough to stop the hiccups. This stuff worked. I ordered more so I have a spare in the glove again and one in my garage.
