"Spivey recommends using gasoline with an 89 or 93 octane rating, if you
can afford it. The fuel is slicker, which means it won't hang around on
your engine valves and other internal parts, eating away at the rubber."

Is this true?

Teh author also claims:

"Old fuel and various debris can collect inside gaskets in the
carburetor. Cleaning the gaskets is a simple process, but one that
should be carried out only by an experienced mechanic, as it involves
disconnecting the fuel tank from the rest of the mower."
