Sometimes you have to refuel where you need to. And there are situations when the 95th is just not at the gas station and there is no other way out, how to add AI-92. But is it possible to mix 95th and 92nd gasoline in one tank?
It is believed that since gasolines with different octane numbers have different densities, they also delaminate in the tank and still do not mix.
Expert opinion
Mikhail Kolodochkincolumnist “Behind the wheel”:
— According to the standard, the density of gasoline has nothing to do with the octane number. And that’s why it won’t hurt if you dilute the 95th gasoline with the 92nd.
Unless, of course, we’re talking about conditioned fuel. But a normal motorist will never fill up with suspicious petrol, even if it is at least half the price.
Conclusion
So is it possible to mix 92nd and 95th gasoline?
If you add AI-95 to AI-92 nothing bad will happen, but in the opposite direction (adding to the 95th) it’s also possible, but not often. Mixing a few times won’t hurt, but if misused it can lead to poor engine performance.
How exactly? The answer is here.
It is optimal to use the fuel recommended by the manufacturer in the instructions and indicated on the back of the tank hatch.
