No, not "at the right place at the right time", but spark timing instead

I performed a full-advance over the summer and didn't have much of a problem with detonation (but a decent bump in FE) and improved low-RPM efficiency.

Now, loads are bit higher (likely due to the colder weather, and the varied resistance from a variety of operating sources -- rolling, viscous, wind, etc.) I hear pinging quite often these days -- so what to do?

- Retard the timing a bit
- Wait for colder weather
- Change the Oil, it's due
- Run 89 Octane (at 10-cents more/gallon, it would only be about $1 every 2-weeks)

The latter has been on my mind -- is the FE bump worth a buck or 2? ...Or is there option "E"?
