Simple,
If you engine requires 91 octane, and you put 87 in it, you will experience a degradation of engine performance, due to the lower octane having faster burn properties.
If your engine requires 87 octane and you put high octane (90-91 octane) fuel into it, you will NOT see a performance boost, and may even see a slight decline in performance.
What 99% of all people don't know is that High Octane fuel actually burns more slowly, than lower octane fuel. This property, allows higher compression prior to detonation, hence more performance at combustion.
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115
It has no octane rating.
As long as they are of the same octane rating, there should be no adverse effects.
Increasing branching increases octane rating.
Octane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane rating of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
