Initially, the native engine of the D-250 motor block of the Motor Sich was deformed for cheap 80th gasoline, but since it is not found in our country, I'm lyinol 95 spirit, which in turn is fraught with burnout of the exhaust valve seat (chances are small, but possible ). It was decided to increase the compression ratio in the combustion chamber and thereby adapt the engine to high-octane gasoline. Perhaps the power has increased, but so far there is no way to check it.
