Octane vs Compression Ratio...

Hello All,

A question about Octane vs Compression ratio:
With the prices of gasoline going sky-high, and the possibility of running lower-octane,
what is the relationship between the two?

If you are going to rebuild an engine, should the compression ratio be high or low if you run 89 octane?
