Octane < Carbon tetrachloride < Methanol
It has no octane rating.
Methanol is often added to petrol as a way to increase the overall octane rating of the fuel, which can improve engine performance and efficiency. Additionally, methanol blending can help reduce harmful emissions and support the use of renewable fuels.
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.

Increasing branching in a hydrocarbon generally increases its octane rating. This is because branching reduces the likelihood of pre-ignition or knocking in the engine, which is a common issue with straight-chain hydrocarbons. Branching increases the efficiency of combustion, leading to a higher octane rating.
