Improved gas - cheating or saving? Which is better to pour? GDrive, EKTO, Ultimate.

There is little eternal debate about which gasoline to pour 92-95-98-100, so there are also "improved" versions of these gasolines. Ecto, Gdrive, Ultimate and other marketing temptation.
Today we will not disassemble gasoline with which octane rating to pour. A few days ago, we talked about this. I hope everyone made the right conclusions. Today we’ll talk about whether it is worth using the so-called “improved” gasoline?
It’s worth more, but how firm are the firm promises to increase power to 14.7%, to increase acceleration to 9.9%. Will they give the engine of your car "superpower" or "cure" a worn motor?
What do marketers promise us? And they promise us: Fuel economy, super dynamics, engine cleanliness and a bunch of goodies. And even the most complete pimped in advertising turns into a super car.
I will not sort out advertising promises and marketing figures. Because it's just advertising. And in a working new car, you will not feel anything. The placebo effect is nothing more. But on the other hand, there is still an effect.
I will just tell my story.
