I would like to know what is the relationship between octane rating and compression ratio.

What i know is that octane rating is a measure of anti detonation of a fuel. Diesel fuel have an octane rating of ~20 and its compression ratio is ~20:1. Gasoline however have an octane rating of ~80 and compression ratio of ~8:1.

So i would like to assume that lower octane rating will give high compression ratio.

ive got 2 question :

1) I dont understand when using an alcohol+gasoline(say e85,its octane rating is 105) fuel, the engines compression ratio should be ~14:1.
2) What happens in an e85 car when im not using the correct fuel percentage?say maybe 15% alcohol
