STIHL 23-jka Chainsaw: Optimal Octane Level for Fuel - 95, 98 or 100?

I normally put 95 and as the instruction says a mixture with red oil stihl 1:50. If I can't buy stihl oil, the mixture says 1:25.

Yeeeeeeeeeeeeeeee! Two and a half horses make four. Seriously, there is a difference there, but is it worth buying a miracle saw fuel .....

Where does this conversion come from? Who's pushing you ... nonsense about the dryness of high-octane fuel? Gasoline is all dry and has no use for lubricating the engine - the engine lubricates itself with oil and its quality is important. Octane is a fuel parameter that describes the resistance of the fuel to detonation combustion, not its lubricating properties.
Most Stihl's manual says 1:50 stihl oil, 1:25 other oil, and that's it.
As a curiosity, I will say that the stihla saw fed with orlen 1:50 oil gave up the ghost after 3 months of work in the forest. But there is something about their oil.
