There is a widespread belief that “improved gasoline is money down the drain.” Who cares, what kind to fill, there would be a gas station of a well-known brand, where they monitor the quality, and the engine will consume everything, maybe even additional chemistry will harm it. From the point of view of chemistry, it is unlikely that the 95th gasoline with a prefix in the name would give a significant increase in power and quality characteristics of the engine.
And in the instructions for cars, manufacturers do not recommend filling in “enhanced” fuel.
Expert opinion
Mikhail Kolodochkin, Reviewer “Behind the wheel”:
– In practice, however, such gasolines have advantages, which is especially noticeable in engines with divided fuel injection. Fuel additives clean the intake valves, combustion chamber and injectors.
In direct injection engines, they operate less efficiently because the fuel is supplied to the combustion chamber directly after the intake valves.
Detergents work differently than car shampoos. They coat the rubbing surfaces with radicals that reduce friction and remove carbon particles. This leads to some increase in engine power.

Whether to buy fuel more expensive – everyone decides for themselves. But it still has meaning. Each fuel company pursues similar goals when developing a proprietary additive package: removing carbon deposits from parts, protecting against corrosion and improving lubrication. The result of all this can be improved fuel efficiency.
