I keep going back and forth about whether I’m imagining it gives better performance or it actually does 😅
I vaguely knew “higher octane” didn’t mean higher percentage of 8-C hydrocarbons but definitely believed the misconception that it was higher energy density. Hm.
It definitely doesn’t have much in the way of sensors (though it does seem to adjust the idle speed in cold weather through some mechanism). It has spark plugs and a carburetor so no dice on coil on pack ignition or fuel injection.
The mechanic I took it to did say he thought it would run better in cold weather with higher octane fuel but didn’t elaborate.
It’s probably a difference of ~20¢ when I fill it yeah, lol. And doesn’t seem to be causing any knocking or other ill effects so no change at worst and real/perceived improvement at best yeah
Knocking is usually pre-ignition and higher octane fuel will reduce that. Knock sensors are one of inputs to the engine control algorithm’s “how much can I mess with timing” game.

There’s very little to run at your fuel consumption rate, so go for it!
